    We report on the successful demonstration of the world's first kW average power, 100 Joule-class, high-energy, nanosecond pulsed diode-pumped solid-state laser (DPSSL), DiPOLE100. Results from the first long-term test for amplification will be presented; the system was operated for 1 hour with 10 ns duration pulses at 10 Hz pulse repetition rate and an average output energy of 105 J and RMS energy stability of approximately 1%. The laser system is based on scalable cryogenic gas-cooled multi-slab ceramic Yb:YAG amplifier technology. The DiPOLE100 system comprises three major sub-systems, a spatially and temporally shaped front end, a 10 J cryo-amplifier and a 100 J cryo-amplifier. The 10 J cryo-amplifier contain four Yb:YAG ceramic gain media slabs, which are diode pumped from both sides, while a multi-pass architecture configured for seven passes enables 10 J of energy to be extracted at 10 Hz. This seeds the 100 J cryo-amplifier, which contains six Yb:YAG ceramic gain media slabs with the multi-pass configured for four passes. Our future development plans for this architecture will be introduced including closed-loop pulse shaping, increased energy, higher repetition rates and picosecond operation. This laser architecture unlocks the potential for practical applications including new sources for industrial materials processing and high intensity laser matter studies as envisioned for ELI [1], HiLASE [2], and the European XFEL [3]. Alternatively, it can be used as a pump source for higher repetition rate PW-class amplifiers, which can themselves generate high-brightness secondary radiation and ion sources leading to new remote imaging and medical applications.

    International audience; Metal atoms in solid and liquid helium-4 have attracted some interest either as a way to keep the atoms in a weakly perturbing matrix, or using them as a probe for the helium host medium. Laser sputtering with nanosecond pulsed lasers is the most often used method for atom production, resulting however in a substantial perturbation of the matrix. We show that a much weaker perturbation can be obtained by using femtosecond laser pulses with energy as low as 10 µJ. As an...

  3. Calculation of decay widths of pp{mu}{sub {nu}}{sub ,J}{sup *} ion in non-adiabatic approach

    We calculate decay widths of the metastable pp{mu}{sub {nu}}{sub ,J}{sup *} molecular ion in non-adiabatic approach. The muonic molecular ion can be formed in collision of the excited p{mu}(2s) atoms with H{sub 2}. Then, the decay of the pp{mu}{sub {nu}}{sub ,J}{sup *} system opens a path for the muon from p{mu}(2s) to p{mu}(1s). We employ trial wave function which includes non-adiabatic terms to calculate some radiationless decay widths. The present results of the widths do not agree well with those given in our previous work, however they are more close to recent data of other researchers. (author)

  4. Megajoule-class single-pulse KrF laser test facility as a logical step toward inertial fusion commercialization

    The cost and efficiency of megajoule-class KrF laser single pulse test facilities have been examined. A baseline design is described which illuminates targets with 5 MJ with shaped 10-ns pulses. The system uses 24 main amplifiers and operates with an optics operating fluence of 4.0 J/cm 2 . This system has 9.0% efficiency and costs $200/joule. Tradeoff studies indicate that large amplifier modules and high fluences lead to the lowest laser system costs, but that only a 20% cost savings can be realized by going to amplifier modules larger than 200 kJ and/or fluences greater than 4 J/cm 2 . The role of the megajoule-class single-pulse test facility towards inertial fusion commercialization will also be discussed

    This note presents an update of the B$^0$ $\\rightarrow$ J/$\\psi$($\\mu\\mu$)K$^0_S$($\\pi^+\\pi^-$) analysis in order to obtain the LHCb sensitivity to sin(2$/beta$). We present two selection criteria, one considering only lifetime unbiased cuts and another which includes lifetime biased cuts to reduce further the background contamination. For an integrated luminosity of 2 fb$^-1$ and after L0 trigger, we estimate a yield of 193k events for the B$^0$ $\\rightarrow$ J/$\\psi$($\\mu\\mu$)K$^0_S$ channel with the lifetime unbiased selection criteria, with a total background to signal ration 3.43. For the lifetime biased selection, the signal yield is 208k events and the background to signal ratio is to 0.63. The statistical sensitivity on sin(2$/beta$) is found to be 0.023 and 0.020 for the unbiased and biased selections, respectively.

    Observation of 16 mu /sup +/ mu /sup -/ pairs of invariant mass greater than 2.7 GeV/c/sup 2/ in the reaction pp to mu /sup +/ mu /sup -/+anything at square root s=52 GeV at the CERN Intersecting Storage Rings (ISR) is reported. These events can be interpreted as originating from J(3.1) decay into mu /sup +/ mu /sup -/. Their p/sub T/ distribution suggests a hadronic production. The cross section for J production is given and compared to the cross section for single lepton production. It is concluded that J(3.1) production cannot fully account for single lepton production.

    The direct $C\\!P$ asymmetries of the decays $B^0 \\rightarrow K^{*0} \\mu^+ \\mu^-$ and $B^+ \\rightarrow K^{+} \\mu^+ \\mu^-$ are measured using $pp$ collision data corresponding to an integrated luminosity of 3.0$\\mbox{fb}^{-1}$ collected with the LHCb detector. The respective control modes $B^0 \\rightarrow J/\\psi K^{*0}$ and $B^+ \\rightarrow J/\\psi K^{+}$ are used to account for detection and production asymmetries. The measurements are made in several intervals of $\\mu^+ \\mu^-$ invariant mass squared, with the $\\phi(1020)$ and charmonium resonance regions excluded. Under the hypothesis of zero $C\\!P$ asymmetry in the control modes, the average values of the asymmetries are \\begin{align} {\\cal A}_{C\\!P}(B^0 \\rightarrow K^{*0} \\mu^+ \\mu^-) &= -0.035 \\pm 0.024 \\pm 0.003, \\cr {\\cal A}_{C\\!P}(B^+ \\rightarrow K^{+} \\mu^+ \\mu^-) &= \\phantom{-}0.012 \\pm 0.017 \\pm 0.001, \\end{align} where the first uncertainties are statistical and the second are due to systematic effects. Both measurements are consistent with t...

    A measurement of the $C\\!P$ asymmetry in $B^+ \\rightarrow K^+ \\mu^+ \\mu^-$ decays is presented using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb $^{-1}$, recorded by the LHCb experiment during 2011 at a centre-of-mass energy of 7 TeV. The measurement is performed in seven bins of $\\mu^+ \\mu^-$ invariant mass squared in the range 0.05 < $q^{2}$ < 22.00 GeV$^{2}/c^4$, excluding the ${J\\mskip -3mu/\\mskip -2mu \\psi\\mskip 2mu}$ and $\\psi{(2S)}$ resonance regions. Production and detection asymmetries are corrected for using the $B^+ \\rightarrow J\\mskip -3mu/\\mskip -2mu \\psi\\mskip 2mu K^+$ decay as a control mode. Averaged over all the bins, the $C\\!P$ asymmetry is found to be ${{\\cal A}_{C\\!P} = 0.000\\pm 0.033\\mbox{ (stat.)} \\pm0.005 \\mbox{ (syst.)} \\pm 0.007\\mbox{ }(J\\mskip -3mu/\\mskip -2mu \\psi\\mskip 2mu K^+)}$, where the third uncertainty is due to the $C\\!P$ asymmetry of the control mode. This is consistent with the Standard Model prediction.

    The products of the electron width of the J/psi meson and the branching fraction of its decays to the lepton pairs were measured using data from the KEDR experiment at the VEPP-4M electron-positron collider. The results are GAMMA{sub ee}xGAMMA{sub ee}/GAMMA=0.3323+-0.0064(stat.)+-0.0048(syst.) keV, GAMMA{sub ee}xGAMMA{sub m}u{sub m}u/GAMMA=0.3318+-0.0052(stat.)+-0.0063(syst.) keV. Their combinations GAMMA{sub ee}x(GAMMA{sub ee}+GAMMA{sub m}u{sub m}u)/GAMMA=0.6641+-0.0082(stat.)+-0.0100(syst.) keV, GAMMA{sub ee}/GAMMA{sub m}u{sub m}u=1.002+-0.021(stat.)+-0.013(syst.) can be used to improve the accuracy of the leptonic and full widths and test leptonic universality. Assuming emu universality and using the world average value of the lepton branching fraction, we also determine the leptonic GAMMA{sub ll}=5.59+-0.12 keV and total GAMMA=94.1+-2.7 keV widths of the J/psi meson.

    Most millisecond pulsars, like essentially all other radio pulsars, show timing errors well in excess of what is expected from additive radiometer noise alone. We show that changes in amplitude, shape, and pulse phase for the millisecond pulsar J1713+0747 cause this excess error. These changes appear to be uncorrelated from one pulse period to the next. The resulting time of arrival (TOA) variations are correlated across a wide frequency range and is observed with different backend processors on different days, confirming that they are intrinsic in origin and not an instrumental effect or caused by strongly frequency-dependent interstellar scattering. Centroids of single pulses show an rms phase variation Almost-Equal-To 40 {mu}s, which dominates the timing error and is the same phase jitter phenomenon long known in slower spinning, canonical pulsars. We show that the amplitude modulations of single pulses are modestly correlated with their arrival time fluctuations. We also demonstrate that single-pulse variations are completely consistent with arrival time variations of pulse profiles obtained by integrating N pulses such that the arrival-time error decreases proportional to 1/{radical}N. We investigate methods for correcting TOAs for these pulse-shape changes, including multi-component TOA fitting and principal component analysis. These techniques are not found to improve the timing precision of the observations. We conclude that when pulse-shape changes dominate timing errors, the timing precision of PSR J1713+0747 can be only improved by averaging over a larger number of pulses.

    AUTHOR|(INSPIRE)INSPIRE-00266880

    This thesis reports the branching fraction measurement of the rare Cabibbo-suppressed decay $\\Lambda_{b}\\rightarrow p\\pi^{-}\\mu^{+}\\mu^{-}$. The decay is observed for the first time with a $5.5\\sigma$ deviation from the background-only hypothesis. This is the first observation of a $b\\rightarrow d$ quark transition in the baryon sector. The dataset used for the measurement corresponds to 3 $\\mathrm{fb}^{-1}$ of $pp$ collisions collected at the LHCb experiment at CERN. The branching fraction is measured using $\\Lambda_{b}\\rightarrow J/\\psi(\\rightarrow\\mu^{+}\\mu^{-}) p \\pi^{-}$ as a normalisation channel and is measured as \\begin{equation*} \\mathcal{B}(\\Lambda_{b}\\rightarrow p\\pi^{-}\\mu^{+}\\mu^{-}) = (6.9 \\pm 1.9 \\pm 1.1^{+1.3}_{-1.0})\\times 10^{-8}, \\end{equation*} where the first error is the statistical uncertainty, the second is the systematic uncertainty and the third is the uncertainty on $\\mathcal{B}(\\Lambda_{b}\\rightarrow J/\\psi(\\rightarrow\\mu^{+}\\mu^{-}) p \\pi^{-})$. The measurement of $ \\mathcal{B}...

    The observation of the $\\mathrm{Z}$ boson rare decay to a $\\psi$ meson and two oppositely charged same-flavour leptons, $\\ell^+ \\ell^-$, where $\\psi$ represents the sum of $\\mathrm{J}/\\psi$ and $\\psi(\\mathrm{2S})\\to\\mathrm{J}/\\psi\\, X$, and $\\ell=\\mu,\\mathrm{e}$, is presented. The data sample used corresponds to an integrated luminosity of $35.9\\,\\mathrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of $13\\,\\mathrm{TeV}$ accumulated by the CMS experiment at the LHC. The signal is observed with a significance in excess of 5 standard deviations. Removing contributions from $\\psi(\\mathrm{2S})$ decays to $\\mathrm{J}/\\psi$, the signal is interpreted as being entirely from $\\mathrm{Z}\\to\\mathrm{J}/\\psi\\,\\ell^+\\ell^-$, with its fiducial branching fraction relative to that of the decay $\\mathrm{Z}\\to\\mu^+\\mu^-\\mu^+\\mu^-$ measured to be $$\\frac{\\mathcal{B}(\\mathrm{Z}\\to\\mathrm{J}/\\psi\\,\\ell^+\\ell^-)}{\\mathcal{B}(\\mathrm{Z}\\to\\mu^+\\mu^-\\mu^+\\mu^-)}=0.70\\pm 0.18\\, \\mathrm{(stat)} \\pm 0.05\\, \\mathrm{(s...

    This thesis shows the strategy to extract the $B_s\\rightarrow\\mu^{+}\\mu^{-}$ branching ratio from the LHCb data, calibrating all the steps using control channels and not relying on the simulation. This branching ratio is very sensitive to New Physics effects, and can get large enhancements within SuperSymmetry or other Standard Model extensions. The signal is separated from background according to three properties: the invariant mass, the muon identification, and the geometrical properties of the decay. The multivariate analysis designed to combine the geometrical properties is also shown here. The ration of offline reconstruction efficiencies between signal ($B_s\\rightarrow\\mu^{+}\\mu^{-}$) and normalization channels ($B^{+}\\rightarrow J/\\psi(\\mu^{+}\\mu^{-}K^{+}$ and/or $B_d\\rightarrow K ^{+}\\pi^{-}$ ) can be extracted using the ratio of different control channels (for instance, $B_d\\rightarrow J/\\psi (\\mu^{+}\\mu^{-}) K^{*0}(K^{+}\\pi^{-}))$ with a few percent precision. The ratio of trigger efficiencies can b...

    Radiation effects in high temperature superconducting (HTSC) films, influenced by pulse electron and ion beams, are considered. The electron beams had kinetic energies E = 200-300 keV, current densities j = 10-2000 A/cm{sup 2} and pulse duration t{sub p} = 0.3-1.2 {mu}s; and ion beams of carbon, copper and silver with E = 200-350 keV, t{sub p} = 0.3 {mu}s and j = 5-15 A/cm{sup 2} were used in the experiments. The results of resistive threshold characteristics measurements by HTSC are described. Questions about the increase of critical current and electric strength of vacuum gaps with electrodes from HTSC are discussed. (orig.).

    The differential branching fraction of the decay $\\Lambda_b^0\\rightarrow\\Lambda\\mu^+\\mu^-$ is measured as a function of the square of the dimuon invariant mass, $q^2$. A yield of $78\\pm12$ $\\Lambda_b^0\\rightarrow\\Lambda\\mu^+\\mu^-$ decays is observed using data, corresponding to an integrated luminosity of 1.0,fb$^{-1}$, collected by the LHCb experiment at a centre-of-mass energy of 7\\,TeV. A significant signal is found in the $q^2$ region above the square of the $J/\\psi$ mass, while at lower-$q^2$ values upper limits are set on the differential branching fraction. Integrating the differential branching fraction over $q^2$, while excluding the $J/\\psi$ and $\\psi(2S)$ regions, gives a branching fraction of $B(\\Lambda_b^0\\rightarrow\\Lambda\\mu^+\\mu^-)=(0.96\\pm 0.16(stat)\\pm 0.13(syst)\\pm 0.21 (\\mathrm{norm}))\\times 10^{-6}$, where the uncertainties are statistical, systematic and due to the normalisation mode, $\\Lambda_b^0\\rightarrow J/\\psi\\Lambda$, respectively.

    We study the resonant contributions in the process anti B{sup 0} {yields} K{sup -} {pi}{sup +}{mu}{sup +}{mu}{sup -} with the K{sup -}{pi}{sup +} invariant mass square m{sup 2}{sub K{pi}} element of [1, 5] GeV{sup 2}. Width effects of the involved strange mesons, K{sup *}(1410), K{sup *}{sub 0}(1430), K{sup *}{sub 2}(1430), K{sup *}(1680), K{sup *}{sub 3}(1780) and K{sup *}{sub 4}(2045), are incorporated. In terms of the helicity amplitudes, we derive a compact form for the full angular distributions, through which the branching ratios, forward-backward asymmetries and polarizations are attained. We propose that the uncertainties in the B {yields} K{sup *}{sub J} form factors can be pinned down by the measurements of a set of SU(3)-related processes. Using results from the large energy limit, we derive the dependence of branching fractions on the m{sub K{pi}}, and find that the K{sup *}{sub 2} resonance has a clear signature, in particular, in the transverse polarizations.

    A search for the decays $B^0_s \\to \\mu^+\\mu^-\\mu^+\\mu^-$ and $B^0 \\to \\mu^+\\mu^-\\mu^+\\mu^-$ in a data sample of 1.0 inverse femtobarns collected with the LHCb detector in 2011 is discussed. In the SM, the non-resonant $B^0_s \\to \\mu^+\\mu^-\\mu^+\\mu^-$ branching fraction is expected to be < 10$^{-10}$. One signal candidate is observed in the $B_d$ channel, and no signal candidates are observed in the $B_s$ channel. These observed events are consistent with the expected backgrounds and upper limits on the branching fractions are set at $\\cal{B}(B^0_s \\to \\mu^+\\mu^-\\mu^+\\mu^-) < 1.3 \\times 10^{-8}$ and $\\cal{B}(B^0 \\to \\mu^+\\mu^-\\mu^+\\mu^-) < 5.4 \\times 10^{-9}$ at 95 % CL.

  3. Research and Development for the Mu2e Extinction Monitor

    2016-01-01

    Mu2e is a planned experiment to search for flavor-violating conversion from a muon to an electron. The experiment will use a pulsed 8 GeV proton beam to produce muons which will then stop in an aluminum target. Mu2e will search for the $\\mu^- + Al \\rightarrow e^- + Al$ process. For Mu2e, an extinction rate of 10$^{-10}$ is required to reduce the backgrounds to an acceptable level. Extinction is the ratio of the amount of protons striking the production target between beam pulses to the number striking it during the beam pulse. One of the backgrounds, off-target interactions, was simulated using G4beamline and Fermilab's Grid setup to confirm that an extinction rate of 10$^{-10}$ is possible. The extinction level will be measured by the extinction monitor which will include scintillation counters read out by photomultiplier tubes. In order to build a beam time profile, low fake responses (after pulses) are needed in the photomultiplier tubes. This thesis determines the best combination of resistors, voltage, and other components that provide the lowest after pulse rate.

    A 1J LD pumped Nd;YAG pulsed laser was designed. The laser uses an oscillation and two-staged amplification structure, and applies diode bar integrated array as side-pump. The TEC temperature control device combing liquid cooling system is organized to control the temperature of the laser system. This study also analyzed the theoretical threshold of working material, the effect of thermal lens and the basic principle of laser amplification. The results showed that the laser system can achieve 1J, 25Hz pulse laser output, and the laser pulse can be output at two width: 6-7ns and 10ns, respectively, and the original beam angle is 1.2mrad. The laser system is characterized by small size, light weight, as well as good stability, which make it being applied in varied fields such as photovoltaic radar platform and etc

  6. Transmission of laser pulses with high output beam quality using step-index fibers having large cladding

    An apparatus and method for transmission of laser pulses with high output beam quality using large core step-index silica optical fibers having thick cladding, are described. The thick cladding suppresses diffusion of modal power to higher order modes at the core-cladding interface, thereby enabling higher beam quality, M.sup.2, than are observed for large core, thin cladding optical fibers. For a given NA and core size, the thicker the cladding, the better the output beam quality. Mode coupling coefficients, D, has been found to scale approximately as the inverse square of the cladding dimension and the inverse square root of the wavelength. Output from a 2 m long silica optical fiber having a 100 .mu.m core and a 660 .mu.m cladding was found to be close to single mode, with an M.sup.2=1.6. Another thick cladding fiber (400 .mu.m core and 720 .mu.m clad) was used to transmit 1064 nm pulses of nanosecond duration with high beam quality to form gas sparks at the focused output (focused intensity of >100 GW/cm.sup.2), wherein the energy in the core was laser pulses was about 6 ns. Extending the pulse duration provided the ability to increase the delivered pulse energy (>20 mJ delivered for 50 ns pulses) without damaging the silica fiber.

    We will present the integral measurement of the neutron inelastic cross section of ^235U leading to the 26-minute, E*=76.5 eV isomer state. Small samples (5-20 microgm) of isotope-enriched ^235U were activated in the central cavity of the CALIBAN pulsed reactor at Valduc where a nearly pure fission neutron spectrum is produced with a typical fluence of 3x10^14 n/cm^2. After 30 minutes the samples were removed from the reactor and counted in an electrostatic-deflecting electron spectrometer that was optimized for the detection of ^235mU conversion electrons. From the decay curve analysis of the data, the 26-minute ^235mU component was extracted. Preliminary results will be given and compared to gamma-cascade calculations assuming complete K-mixing or with no K-mixing.

    Two magnetic pulse compression circuits (MPCC), for two different plasma devices, are presented. The first is a 20 J/pulse, 3-stage circuit designed to trigger a low pressure discharge. The circuit has 16-18 kV working voltage, and 200 nF in each stage. The saturable inductors are realized with toroidal 25 {mu}m strip-wound cores, made of a Fe-Ni alloy, with 1.5 T saturation induction. The total magnetic volume is around 290 cm{sup 3}. By using a 25 kV/1 A thyratron as a primary switch, the time compression is from 3.5 {mu}s to 450 ns, in a short-circuit load. The second magnetic pulser is a 200 J/pulse circuit, designed to drive a high average power plasma focus soft X-ray source, for X-ray microlithography as the main application. The 3-stage pulser should supply a maximum load current of 100 kA with a rise-time of 250 - 300 ns. The maximum pulse voltage applied on the plasma discharge chamber is around 20 - 25 kV. The three saturable inductors in the circuit are made of toroidal strip-wound cores with METGLAS 2605 CO amorphous alloy as the magnetic material. The total, optimized mass of the magnetic material is 34 kg. The maximum repetition rate is limited at 100 Hz by the thyratron used in the first stage of the circuit, the driver supplying to the load about 20 kW average power.

    The differential branching fraction of the rare decay $\\Lambda^{0}_{b} \\rightarrow \\Lambda^0 \\mu^+\\mu^-$ is measured as a function of $q^{2}$, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to an integrated luminosity of $3.0 \\mbox{ fb}^{-1}$, collected by the LHCb experiment. Evidence of signal is observed in the $q^2$ region below the square of the $J/\\psi$ mass. Integrating over $15 < q^{2} < 20 \\mbox{ GeV}^2/c^4$ the branching fraction is measured as $d\\mathcal{B}(\\Lambda^{0}_{b} \\rightarrow \\Lambda^0 \\mu^+\\mu^-)/dq^2 = (1.18 ^{+ 0.09} _{-0.08} \\pm 0.03 \\pm 0.27) \\times 10^{-7} ( \\mbox{GeV}^{2}/c^{4})^{-1}$, where the uncertainties are statistical, systematic and due to the normalisation mode, $\\Lambda^{0}_{b} \\rightarrow J/\\psi \\Lambda^0$, respectively. In the $q^2$ intervals where the signal is observed, angular distributions are studied and the forward-backward asymmetries in the dimuon ($A^{l}_{\\rm FB}$) and hadron ($A^{h}_{\\r...

    A search for the decays $B^0_{s}\\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-$ and $B^0 \\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-$ is performed using data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected with the LHCb detector in 2011. The number of candidates observed is consistent with the expected background and, assuming phase-space models of the decays, limits on the branching fractions are set: ${\\cal B}(B^0_{s}\\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-) < 1.6 \\ (1.2) \\times 10^{-8}$ and ${\\cal B}(B^0 \\rightarrow \\mu^+ \\mu^- \\mu^+ \\mu^-)< 6.6 \\ (5.3) \\times 10^{-9}$ at 95% (90%) confidence level. In addition, limits are set in the context of a supersymmetric model which allows for the $B^0_{(s)}$ meson to decay into a scalar ($S$) and pseudoscalar particle ($P$), where $S$ and $P$ have masses of 2.5 GeV/c$^2$ and 214.3 MeV/c$^2$, respectively, both resonances decay into $\\mu^+\\mu^-$. The branching fraction limits for these decays are ${\\cal B}(B^0_{s}\\rightarrow SP) < 1.6 \\ (1.2) \\times 10^{-8}$...

  12. Research and Development for the Mu2e Extinction Monitor

    Mu2e is a planned experiment to search for flavor-violating conversion from a muon to an electron. The experiment will use a pulsed 8 GeV proton beam to produce muons which will then stop in an aluminum target. Mu2e will search for the μ - + Al → e - + Al process. For Mu2e, an extinction rate of 10 -10 is required to reduce the backgrounds to an acceptable level. Extinction is the ratio of the amount of protons striking the production target between beam pulses to the number striking it during the beam pulse. One of the backgrounds, off-target interactions, was simulated using G4beamline and Fermilab's Grid setup to confirm that an extinction rate of 10 -10 is possible. The extinction level will be measured by the extinction monitor which will include scintillation counters read out by photomultiplier tubes. In order to build a beam time profile, low fake responses (after pulses) are needed in the photomultiplier tubes. This thesis determines the best combination of resistors, voltage, and other components that provide the lowest after pulse rate.

    A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets ($\\mu^\\pm \\mu^\\pm \\mathrm{j j}$). The data correspond to an integrated luminosity of 19.7 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. No excess of events is observed beyond the expected standard model background and upper limits are set on $|V_{\\mu\\mathrm{N}}|^2$ as a function of Majorana neutrino mass $\\mathrm{m}_{\\mathrm{N}}$ for masses in the range of 40-500 GeV, where $|V_{\\mu\\mathrm{N}}|$ is the mixing element of the heavy neutrino with the standard model muon neutrino. The limits obtained are $|V_{\\mu\\mathrm{N}}|^2 \\le 0.00470$ for $\\mathrm{m}_{\\mathrm{N}} = 90$ GeV, $|V_{\\mu\\mathrm{N}}|^2 \\le 0.0123$ for $\\mathrm{m}_{\\mathrm{N}} = 200$ GeV, and $|V_{\\mu\\mathrm{N}}|^2 \\le 0.583$ for $\\mathrm{m}_{\\mathrm{N}} = 500$ GeV.

  14. Development of optical parametric chirped-pulse amplifiers and their applications

    In this work, optical pulse amplification by parametric chirped-pulse amplification (OPCPA) has been applied to the generation of high-energy, few-cycle optical pulses in the near-infrared (NIR) and infrared (IR) spectral regions. Amplification of such pulses is ordinarily difficult to achieve by existing techniques of pulse amplification based on standard laser gain media followed by external compression. Potential applications of few-cycle pulses in the IR have also been demonstrated. The NIR OPCPA system produces 0.5-terawatt (10 fs,5 mJ) pulses by use of noncollinearly phase-matched optical parametric amplification and a down-chirping stretcher and up-chirping compressor pair. An IR OPCPA system was also developed which produces 20-gigawatt (20 fs,350 {mu}J) pulses at 2.1 {mu}m. The IR seed pulse is generated by optical rectification of a broadband pulse and therefore it exhibits a self-stabilized carrier-envelope phase (CEP). In the IR OPCPA a common laser source is used to generate the pump and seed resulting in an inherent sub-picosecond optical synchronization between the two pulses. This was achieved by use of a custom-built Nd:YLF picosecond pump pulse amplifier that is directly seeded with optical pulses from a custom-built ultrabroadband Ti:sapphire oscillator. Synchronization between the pump and seed pulses is critical for efficient and stable amplification. Two spectroscopic applications which utilize these unique sources have been demonstrated. First, the visible supercontinuum was generated in a solid-state media by the infrared optical pulses and through which the carrier-envelope phase (CEP) of the driving pulse was measured with an f-to-3f interferometer. This measurement confirms the self-stabilization mechanism of the CEP in a difference frequency generation process and the preservation of the CEP during optical parametric amplification. Second, high-order harmonics with energies extending beyond 200 eV were generated with the few

    This paper presents a novel, fully integrated transmitter for 3-5 GHz pulsed UWB. The BPSK modulation transmitter has been implemented in SMIC CMOS 0.13 μm technology with a 1.2-V supply voltage and a die size of 0.8 x 0.95 mm 2 . This transmitter is based on the impulse response filter method, which uses a tunable R paralleled with a LC frequency selection network to realize continuously adjustable pulse parameters, including bandwidth, width and amplitude. Due to the extremely low duty of the pulsed UWB, a proposed output buffer is employed to save power consumption significantly. Finally, measurement results show that the transmitter consumes only 16.3 pJ/pulse to achieve a pulse repetition rate of 100 Mb/s. Generated pulses strictly comply with the FCC spectral mask. The continuously variable pulse width is from 900 to 1.5 ns and the amplitude with the minimum 178 mVpp and the maximum 432 mVpp can be achieved. (semiconductor integrated circuits)

    A search for $C\\!P$ violation in the rare decay $\\Lambda^0_b \\to p K^- \\mu^+ \\mu^-$ is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and is potentially sensitive to new sources of $C\\!P$ violation. The study is based on a data sample of proton-proton collisions recorded with the LHCb experiment, corresponding to an integrated luminosity of $3\\mathrm{fb}^{-1}$. Two observables that are sensitive to different manifestations of $C\\!P$ violation are measured, $\\Delta\\mathcal{A}_{C\\!P} \\equiv \\mathcal{A}_{C\\!P}(\\Lambda^0_b \\to p K^- \\mu^+ \\mu^-)-\\mathcal{A}_{C\\!P}(\\Lambda^0_b\\to pK^- J/\\psi)$ and $a_{C\\!P}^{\\widehat{T}_{\\mathrm{odd}}}$, where the latter is based on asymmetries in the angle between the $\\mu^+\\mu^-$ and $p K^-$ decay planes. No evidence for $C\\!P$ violation is found.

    An experimental investigation has been made on plasma closure in pinholes irradiated by Nd glass laser pulses; 300--500-..mu..m diam pinholes of various materials and thicknesses have been irradiated by 20--100-J 300-psec FWHM pulses on the Janus laser system. Calorimetry measurements have yielded data on pinhole energy transmission and intensity loading on the periphery of the pinhole. Ultrafast streak photography measurements indicate effective closure velocities of 2--5 x 10/sup 7/ cm/sec. Scattered light measurements have shown the transmission loss through a typical spatial filter configuration to be primarily refractive in nature.

  19. Toward the first study of chemical reaction dynamics of Mu with vibrational-state-selected reactants in the gas phase: The Mu+H2*(v=1) reaction by stimulated Raman pumping

    Stimulated Raman pumping (SRP) is used to produce H 2 in its first vibrational state, in order to measure, for the first time, the Mu+H 2 *(v=1)→MuH+H reaction rate at room temperature, as a prototypical example of new directions in gas-phase muonium chemistry, utilizing the pulsed muon beam and a new dedicated laser system at the RIKEN/RAL Laboratory. Reported here is a preliminary result but the final results are expected to provide definitive new tests of reaction rate theory on the highly accurate H 3 potential energy surface. The major difficulty in this experiment, compared to the standard SRP process, is to ensure a homogeneous excitation over a volume of several cm 3 and of sufficient intensity to ensure a measurable Mu relaxation rate. The techniques used to accomplish this are described. The experiment utilizes the 2nd harmonic output of a Nd:YAG laser (532 nm) with pulse energies up to 500 mJ at a repetition rate of 25 Hz. Different optical setups have been constructed and tested in order to optimize the number of laser-pumped H 2 molecules and their overlap with the stopping profile of the muon beam in the reaction cell (total volume ∼100x40x4mm 3 ). The first result of this experiment gives a measured relaxation rate due to laser excitation of λ*=0.085±0.051μs -1 , consistent with theory but limited by both low statistics and particularly a high background relaxation rate.

    A search for the rare decays $B_s^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-$ and $B^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-$ is performed in a data set corresponding to an integrated luminosity of 3.0 fb$^{-1}$ collected by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. Decay candidates with pion pairs that have invariant mass in the range 0.5-1.3 GeV/$c^2$ and with muon pairs that do not originate from a resonance are considered.

    Pulse repetition rates and the number of laser pulses are among the most important parameters that do affect the analysis of solid materials by laser induced breakdown spectroscopy, and the knowledge of their effects is of fundamental importance for suggesting analytical strategies when dealing with laser ablation processes of polymers. In this contribution, the influence of these parameters in the ablated mass and in the features of craters was evaluated in polypropylene and high density polyethylene plates containing pigment-based PbCrO{sub 4}. Surface characterization and craters profile were carried out by perfilometry and scanning electron microscopy. Area, volume and profile of craters were obtained using Taylor Map software. A laser induced breakdown spectroscopy system consisted of a Q-Switched Nd:YAG laser (1064 nm, 5 ns) and an Echelle spectrometer equipped with ICCD detector were used. The evaluated operating conditions consisted of 10, 25 and 50 laser pulses at 1, 5 and 10 Hz, 250 mJ/pulse (85 J cm{sup -2}), 2 {mu}s delay time and 6 {mu}s integration time gate. Differences in the topographical features among craters of both polymers were observed. The decrease in the repetition rate resulted in irregular craters and formation of edges, especially in polypropylene sample. The differences in the topographical features and ablated masses were attributed to the influence of the degree of crystallinity, crystalline melting temperature and glass transition temperature in the ablation process of the high density polyethylene and polypropylene. It was also observed that the intensities of chromium and lead emission signals obtained at 10 Hz were two times higher than at 5 Hz by keeping the number of laser pulses constant.

    We demonstrate an Er-doped fiber laser (EDFL) mode-locked by a MoS2 saturable absorber (SA), delivering a 256 fs, 2 nJ soliton pulse at 1563.4 nm. The nonlinear property of the SA prepared by magnetron sputtering deposition (MSD) is measured with a modulation depth (MD) of ∼19.48% and a saturable intensity of 4.14 MW/cm2. To the best of our knowledge, the generated soliton pulse has the highest pulse energy of 2 nJ among the reported mode-locked EDFLs based on transition metal dichalcogenides (TMDs). Our results indicate that MSD-grown SAs could offer an exciting platform for high pulse energy and ultrashort pulse generation.

    MuSEUM is an international collaboration aiming at a new precise measurement of the muonium hyperfine structure at J-PARC (Japan Proton Accelerator Research Complex). Utilizing its intense pulsed muon beam, we expect a ten-fold improvement for both measurements at high magnetic field and zero magnetic field. We have developed a sophisticated monitoring system, including a beam profile monitor to measure the 3D distribution of muonium atoms to suppress the systematic uncertainty.

    A neodymium-glass diode-pumped amplifier with a zigzag laser beam propagation through the active medium was elaborated; the amplifier is intended for operation in a repetitively pulsed laser. An amplifier unit with an aperture of 20 Multiplication-Sign 25 mm and a {approx}40-cm long active medium was put to a test. The energy of pump radiation amounts to 140 J at a wavelength of 806 nm for a pump duration of 550 {mu}s. The energy parameters of the amplifier were experimentally determined: the small-signal gain per pass {approx}3.2, the linear gain {approx}0.031 cm{sup -1} with a nonuniformity of its distribution over the aperture within 15%, the stored energy of 0.16 - 0.21 J cm{sup -3}. The wavefront distortions in the zigzag laser-beam propagation through the active element of the amplifier did not exceed 0.4{lambda} ({lambda} = 0.63 {mu}m is the probing radiation wavelength).

  5. Rare Variants in Genes Encoding MuRF1 and MuRF2 Are Modifiers of Hypertrophic Cardiomyopathy

    Full Text Available Modifier genes contribute to the diverse clinical manifestations of hypertrophic cardiomyopathy (HCM, but are still largely unknown. Muscle ring finger (MuRF proteins are a class of muscle-specific ubiquitin E3-ligases that appear to modulate cardiac mass and function by regulating the ubiquitin-proteasome system. In this study we screened all the three members of the MuRF family, MuRF1, MuRF2 and MuRF3, in 594 unrelated HCM patients and 307 healthy controls by targeted resequencing. Identified rare variants were confirmed by capillary Sanger sequencing. The prevalence of rare variants in both MuRF1 and MuRF2 in HCM patients was higher than that in control subjects (MuRF1 13/594 (2.2% vs. 1/307 (0.3%, p = 0.04; MuRF2 22/594 (3.7% vs. 2/307 (0.7%; p = 0.007. Patients with rare variants in MuRF1 or MuRF2 were younger (p = 0.04 and had greater maximum left ventricular wall thickness (p = 0.006 than those without such variants. Mutations in genes encoding sarcomere proteins were present in 19 (55.9% of the 34 HCM patients with rare variants in MuRF1 and MuRF2. These data strongly supported that rare variants in MuRF1 and MuRF2 are associated with higher penetrance and more severe clinical manifestations of HCM. The findings suggest that dysregulation of the ubiquitin-proteasome system contributes to the pathogenesis of HCM.

  6. 50 MW C-band pulse klystron; 50MW C band pulse klystron

    C-band pulse klystron E3746 with an output of 50 MW class was developed jointly with the High-Energy Accelerator Research Organization in the Ministry of Education as the klystron for a linear accelerator. For a large-sized linear accelerator in the next generation, a klystron with higher operating frequency has been required to obtain a compact and efficient accelerator. In E3746, the problem of power resistance during high-frequency operation was solved by mounting a traveling-wave multi-cell output circuit. Moreover, stable operation in the pulse width of 2.5 {mu}s and the output of 54 MW was performed at the same operation efficiency (44%) as the conventional S-band tube by using the frequency (in a C-band frequency band) that is two times as high as the conventional general accelerator.

    A search for the rare decays B0s->pi pi mu mu and B0->pi pi mu mu is performed in a data set corresponding to an integrated luminosity of 3.0 fb-1 collected by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7 and 8TeV. Decay candidates with pion pairs that have invariant mass in the range 0.5--1.3 GeV/c2 and with muon pairs that do not originate from a resonance are considered. The first observation of the decay B0s->pi pi mu mu and the first evidence of the decay B0->pi pi mu mu are obtained and the branching fractions, restricted to the dipion-mass range considered, are measured to be Br(B0s->pi pi mu mu) = (8.6 +/- 1.5 (stat) +/- 0.7 (syst) +/- 0.7 (norm))*10^-8 and Br(B0->pi pi mu mu) = (2.11 +/- 0.51 (stat) +/- 0.15 (syst) +/- 0.16 (norm)) *10^-8, where the third uncertainty is due to the branching fraction of the decay B0->J/psi K*, used as a normalisation.

    In this paper, we report radio observations of the Galactic Center magnetar PSR J1745–2900 at six epochs between 2014 June and October. These observations were carried out using the new Shanghai Tian Ma Radio Telescope at a frequency of 8.6 GHz. Both the flux density and integrated profile of PSR J1745–2900 show dramatic changes from epoch to epoch, showing that the pulsar was in its “erratic” phase. On MJD 56836, the flux density of this magnetar was about 8.7 mJy, which was 10 times larger than that reported at the time of discovery, enabling a single-pulse analysis. The emission is dominated by narrow “spiky” pulses that follow a log-normal distribution in peak flux density. From 1913 pulses, we detected 53 pulses whose peak flux densities are 10 times greater than that of the integrated profile. They are concentrated in pulse phase at the peaks of the integrated profile. The pulse widths at the 50% level of these bright pulses were between 0.°2 and 0.°9, much narrower than that of the integrated profile (∼12°). The observed pulse widths may be limited by interstellar scattering. No clear correlation was found between the widths and peak flux density of these pulses and no evidence was found for subpulse drifting. Relatively strong spiky pulses are also detected in the other five epochs of observation, showing the same properties as those detected in MJD 56836. These strong spiky pulses cannot be classified as “giant” pulses but are more closely related to normal pulse emission.

    The complex AC susceptibility of high T{sub c} superconducting materials has been described in terms of the first seven harmonic component of Fourier series. Has been measured the {chi}{sub n} (n=1,7) of sintered YBa{sub 2}Cu{sub 3}O{sub 7-x} (YBCO) bulk oxygen and hydrogen loaded samples versus amplitude and frequency of AC magnetic field at fixed temperature. The sample have been loaded by {mu}s current pulses electrolysis in an aqueous solution (0.3N LiOH+H{sub 2}O) at room temperature. In addition to the simplicity of the experimental setup, this procedure allows to obtain extremely high equivalent hydrogen/oxygen gas pressure on the surface of the electrodes. The YBCO electrode is polarized by short pulse width (0.5-10 {mu}s) and high power (120 W) peaks with a variable repetition rate (0.1-10000 Hz). The pulses are obtained by an home.made pulse generator. The difference in the behavior of the susceptibilities harmonic component between the deficiency and oxygen or hydrogen loaded samples give us the possibility to connect the susceptibilities with variations of the flux pinning in respect to normal losses in the superconducting materials. The loading can be a good probe to have information on the mechanism of the processes that sustain the critical current density Jc in this situation these affects appear strongly dependent on the loading conditions. By comparison of this measurements has been observed drastic change in behavior of susceptibility.

    The plasma closure of spatial filter pinholes is a critical parameter in the performance of high energy glass laser systems. Using 50 to 100 J, 300 psec FWHM laser pulses on the Janus laser, an investigation has been made on closure effects in 300 ..mu..m to 500 ..mu..m diameter pinholes of various materials and thicknesses. Calorimetry measurements have yielded data on pinhole transmission and intensity loading on the periphery of the pinhole. Ultrafast streak photography measurements indicate effective closure velocities of 2 x 10/sup 7/ cm/sec to 5 x 10/sup 7/ cm/sec. Scattered light measurements have shown the transmission loss through a typical spatial filter configuration to be primarily refractive in nature.

  14. Generation of stable Ps, mJ pulses at high repetition rate for ultrafast diagnostic experiments: Final report

    International Nuclear Information System (INIS)

    Mourou, G.

    1986-10-01

    Nd:Glass amplifiers have very good energy storage capabilities (5 J/cm 2 ), but, the energy extraction is extremely inefficient for short-pulse amplification. At relatively high peak intensities of ∼ 10 GW/cm 2 , nonlinear phase shifts occur, leading to beam wavefront distortion which can result in filamentation and irreversible damage. In order that the peak intensity in the amplifier remain below this damage level, a picosecond pulse can be amplified only to an energy density of ∼ 10 mJ/cm 2 , two orders of magnitude less than the stored energy level of 5 J/cm 2 . We have developed an amplification system, which uses an optical pulse compression technique to circumvent this peak power limitation. This technique is analogous to a method developed over forty years ago for the amplification of radar pulses. Briefly: a long optical pulse is deliberately produced by stretching a short, low-energy pulse, amplified and then compressed. The frequency chirp and the temporal broadening are produced by propagating a high-intensity pulse along a single-mode fiber. At the beginning of the fiber, the pulse undergoes self-phase modulation which produces a frequncy chirp. The chirp is then linearized by the group-velocity dispersion of the fiber. This long, frequency-chirped, pulse is amplified, and then compressed to a pulsewidth approximately equal to 1/Δf, where Δf is the chirped bandwidth. With this system, short pulses can reach the high saturation energy levels, with moderately low peak power levels being maintained in the amplifying medium

    A quasi-continuously pumped picosecond oscillator-amplifier Nd:GdVO 4 laser system based on two identical slabs in a single bounce geometry is reported. Pulse duration is from 160 to 55 ps resulting from the pulse shortening along the extended mode locked train from passively mode locked oscillator, which was measured directly from a single laser shot. The shortest 55 ps long cavity dumped single pulses from the oscillator with the energy of 15±1 μJ and the contrast better than 10 -3 were amplified to the energy of 150 μJ with the contrast better than 10 -3 after the single-pass amplification and to the energy of 400 μJ after the double-pass amplification

    We present photometry in the R-band and linear polarimetry of two cataclysmic variables, namely IPHAS J025827.88 + 635234.9 and IPHAS J051814.33 + 294113.0. The data were obtained from 1-m class tele-scopes of the Aryabhatta Research Institute of Observational Sciences (ARIES; Nainital, India). In addition to the deep eclipse, strong short-period oscillations are also found. We derived a pulse period of (1203 ± 25) s for IPHAS J025827.88 + 635234.9 and (3277 ± 81) s for IPHAS J051814.33 + 294113.0. The presence of both orbital and spin modulations in these systems indicate that they belong to a class of intermediate polars. The full width at half depth of the eclipse is also found to be variable from epoch to epoch for IPHAS J025827.88 + 635234.9. The presence of a variable linear polarization of high value in these two sources indicates that these systems possess a strong magnetic field.

  18. Optimized transmission-line impedance transformers for petawatt-class pulsed-power accelerators

    Full Text Available We have developed 1D analytic and 2D fully electromagnetic models of radial transmission-line impedance transformers. The models have been used to quantify the power-transport efficiency and pulse sharpening of such transformers as a function of voltage pulse width and impedance profile. For the cases considered, we find that in the limit as Γ→0 (where Γ is the ratio of the pulse width to the one-way transit time of the transformer, the transport efficiency is maximized when the impedance profile is exponential. As Γ increases from zero, the optimum profile gradually deviates from an exponential. A numerical procedure is presented that determines the optimum profile for a given pulse shape and width. The procedure can be applied to optimize the design of impedance transformers used in petawatt-class pulsed-power accelerators.

    A search for $B^0_s \\to \\mu+ \\mu^-$ and $B^0 \\to \\mu^+ \\mu^-$ decays is performed using $1.0$ fb$^{-1}$ of $pp$ collision data collected at $\\sqrt{s}=7$\\,TeV with the LHCb experiment at the Large Hadron Collider. For both decays the number of observed events is consistent with expectation from background and Standard Model signal predictions. Upper limits on the branching fractions are determined to be $BR(B^0_s \\to \\mu^+ \\mu^-)< 4.5 \\,(3.8) \\times 10^{-9}$ and $BR(B^0 \\to \\mu^+ \\mu^-) $<1.0\\, (0.81) \\times 10^{-9}$ at 95\\,\\% (90\\,\\%) confidence level.

    The Department of Navy has been pursuing a technology development program for advanced, all-fiber, Ultra Short Pulsed Laser (USPL) systems via Small Business Innovative Research (SBIR) programs. Multiple topics have been published to promote and fund research that encompasses every critical component of a standard USPL system and enable the demonstration of mJ/pulse class systems with an all fiber architecture. This presentation will summarize published topics and funded programs.

  1. Search for the rare decays Bs->mu+mu- and Bd->mu+mu- with the LHCb experiment

    Decays of the B0 and B0s mesons into two muons are extremely rare in the Standard Model as they occur only via helicity suppressed loop diagrams. Their amplitudes can be significantly different in many New Physics models, especially with an extended Higgs sector. Therefore, the search for these decays provides a sensitive probe of physics beyond the Standard Model. A search for the decays B0s ->mu+mu- and B0 ->mu+mu- is performed with about 37 pb-1 of pp collisions at sqrt(s) = 7TeV collected by the LHCb experiment at the Large Hadron Collider at CERN. The analysis relies mostly on control samples with minimal use of the simulation. The observed numbers of events are consistent with the background expectations. The resulting upper limits on the branching ratios are B(B0s->mu+mu-) < 56x10-9 and B(B0->mu+mu-) < 15x10-9 at 95% confidence level. The analysis is presented and prospects are also given for the coming run.

    We have investigated the ultra-fast microdrilling of metals using a compact and cheap fiber amplified passively Q-switched microchip laser. This laser system delivers 100-ps pulses with repetition rates higher than 100 kHz and pulse energies up to 80 {mu}J. The ablation process has been studied on metals with quite different thermal properties (copper, carbon steel and stainless steel). The dependence of the ablation depth per pulse on the pulse energy follows the same logarithmic scaling laws governing laser ablation with sub-picosecond pulses. Structures ablated with 100-ps laser pulses are accompanied only by a thin layer of melted material. Despite this, results with a high level of precision are obtained when using the laser trepanning technique. This simple and affordable laser system could be a valid alternative to nanosecond laser sources for micromachining applications. (orig.)

    A search for the lepton flavour violating decay $\\tau^-\\rightarrow\\mu^-\\mu^+\\mu^-$ is performed with the LHCb experiment. The data sample corresponds to an integrated luminosity of 1.0 fb$^{−1}$ of proton-proton collisions at a centre-of-mass energy of 7 TeV and 2.0 fb$^{−1}$ at 8 TeV. No evidence is found for a signal, and a limit is set at 90% confidence level on the branching fraction, $\\mathcal{B}(\\tau^-\\rightarrow\\mu^-\\mu^+\\mu^-)<4.6\\times10^{−8}$.

    The ATLAS Experiment has conducted a search for the rare decays of Bs and Bd into mu+mu-. 25 fb−1 of integrated luminosity of proton-proton collisions collected during LHC Run 1 were studied to provide new results presented in this talk. An upper limit is set on the branching ratio BR(Bd to mu+mu-) < 4.2×10−10 at 95% confidence level. For Bs, ATLAS measurement yields the branching ratio BR(Bs to mu+mu-)=(0.9+1.1−0.8)×10−9. The result is consistent with the Standard Model expectation and other available measurements.

    Detailed research on the interaction of a 0.53 {mu}m laser pulse with millimeter-scale plasmas produced by a gasbag target on the Shengguang-II facility is presented. The x-ray pinhole images confirm that millimeter-scale plasmas are generated and the x-ray framing images show a temporal window of 0.6-1.1 ns during which the millimeter-scale plasmas exist. The electron temperature is measured with a collective Thomson scattering system, providing 0.64 keV for C{sub 5}H{sub 12} and 1.8 keV for Xe plasmas. The electron density is inferred from the stimulated Raman scattering spectra. The experimental spectra show large differences for C{sub 5}H{sub 12}- and Xe-filled gasbags. A one-dimensional code based upon steady-state, kinetic linear theory is applied to calculate the stimulated Raman scattering spectra. Excellent agreement between the calculated and experimental results shows that the plasma parameters, especially the electron density and the temperature, dominate the disruption behavior of stimulated Raman scattering. The results also indicate that stimulated Raman scattering is probably located within specific region of the gasbag. The time-integrated reflectivity of both the stimulated Raman and Brillouin scattering is at a low level, even in the conditions of high laser intensity (1.5 Multiplication-Sign 10{sup 15} W/cm{sup 2}) and no beam-smoothing. The experimental results are promising for future ignition experiments with a 0.53 {mu}m laser as the driver.

    A recently developed source of ultraviolet radiation, based on optical soliton propagation in a gas-filled hollow-core photonic crystal fiber, is applied here to angle-resolved photoemission spectroscopy (ARPES). Near-infrared femtosecond pulses of only few {\\mu}J energy generate vacuum ultraviolet (VUV) radiation between 5.5 and 9 eV inside the gas-filled fiber. These pulses are used to measure the band structure of the topological insulator Bi2Se3 with a signal to noise ratio comparable to ...

  8. Microwave pulse generation by photoconductive switching

    Laser activated photoconductive semiconductor switching shows significant potential for application in high power microwave generation. Primary advantages of this concept are: small size, light weight, ruggedness, precise timing and phasing by optical control, and the potential for high peak power in short pulses. Several concepts have been suggested for microwave generation using this technology. They generally fall into two categories (1) the frozen wave generator or (2) tuned cavity modulation, both of which require only fast closing switches. We have been exploring a third possibility requiring fast closing and opening switches, that is the direct modulation of the switch at microwave frequencies. Switches have been fabricated at LLNL using neutron irradiated Gallium Arsenide which exhibit response times as short as 50 ps at low voltages. We are in the process of performing high voltage tests. So far, we have been able to generate 2.4 kV pulses with approximately 340 ps response time (FWHM) using approximately a 200..mu..J optical pulse. Experiments are continuing to increase the voltage and improve the switching efficiency. 3 refs., 6 figs.

    A search is performed for the lepton number violating decay $B^{+}\\rightarrow h^- \\mu^+ \\mu^+$, where $h^-$ represents a $K^-$ or a $\\pi^-$, using data from the LHCb detector corresponding to an integrated luminosity of $36pb^{-1}$. The decay is forbidden in the Standard Model but allowed in models with a Majorana neutrino. No signal is observed in either channel and limits of $B(B^{+} \\rightarrow K^- \\mu^+ \\mu^+) < 5.4\\times 10^{-8}$ and $B(B^{+} \\rightarrow \\pi^- \\mu^+ \\mu^+) < 5.8\\times 10^{-8}$ are set at the 95% confidence level. These improve the previous best limits by factors of 40 and 30, respectively.

    We report on the generation of high energy femtosecond pulses at 1 MHz repetition rate from a fiber laser pumped optical parametric amplifier (OPA). Nonlinear bandwidth enhancement in fibers provides the intrinsically synchronized signal for the parametric amplifier. We demonstrate large tunability extending from 700 nm to 1500 nm of femtosecond pulses with pulse energies as high as 1.2 muJ when the OPA is seeded by a supercontinuum generated in a photonic crystal fiber. Broadband amplification over more than 85 nm is achieved at a fixed wavelength. Subsequent compression in a prism sequence resulted in 46 fs pulses. With an average power of 0.5 W these pulses have a peak-power above 10 MW. In particular, the average power and pulse energy scalability of both involved concepts, the fiber laser and the parametric amplifier, will enable easy up-scaling to higher powers.

    The Flavour Changing Neutral Current decay B to mu mu K, which only occurs via loop processes in the SM, is sensitive to contributions from a variety of possible new physics sources. LHCb, the dedicated b physics experiment at the LHC, will record an unprecedented number of B to mu mu K decays, allowing precision measurements of a large number of variables, which will provide evidence or place constraints for physics beyond the SM. This poster gives a short overview of the detector, introduces some of these variables and presents a selection for B to mu mu K.

    A constant-time, Carr-Purcell-Meiboom-Gill (CPMG) transverse relaxation, R{sub 2}, dispersion experiment for carbonyl carbons was designed and executed to detect {mu}s-ms time-scale dynamics of protein backbone carbonyl sites. Because of the large (ca. 55 Hz) C{sub {alpha}}-C' J-coupling, the carbonyl signal intensity is strongly modulated as the spacing between CPMG pulses is varied, in uniformly {sup 13}C enriched proteins, unless care is taken to minimize the perturbation of the C{sub {alpha}} magnetization by the CPMG pulses. CPMG pulse trains consisting of either a band-selective pulse, such as RE-BURP, or rectangular (with an excitation null in the C{sub {alpha}} region of the spectrum) pulses were employed in order to minimize C' signal modulation by C{sub {alpha}}-C' J-coupling. The performance of these types of CPMG refocusing pulses was assessed by computer simulation, and by comparing dispersion profiles measured for (1) uniformly [{sup 13}C,{sup 15}N, {sup 2}H] ({sup 2}H at non-labile hydrogen sites) labeled, and (2) uniformly {sup 15}N/selectively-{sup 13}C' labeled samples of HIV-1 protease bound to a potent inhibitor, DMP323. In addition, because the uniformly {sup 13}C/{sup 15}N/{sup 2}H labeled sample was well suited to measure {sup 15}N and {sup 1}H R{sub 2} dispersion as well as {sup 13}C' dispersion, conformational exchange in the inter subunit {beta}-sheet hydrogen-bond network of the inhibitor-bound protease was elucidated using relaxation dispersion data of all three types of nuclei.

    For the non-destructive identification of pigments and colorants in works of art, in archaeological and in forensic materials, a wide range of analytical techniques can be used. Bearing in mind that every method holds particular limitations, two complementary spectroscopic techniques, namely confocal {mu}-Raman spectroscopy ({mu}-RS) and {mu}-X-ray fluorescence spectroscopy ({mu}-XRF), were joined in one instrument. The combined {mu}-XRF and {mu}-RS device, called PRAXIS unites both complementary techniques in one mobile setup, which allows {mu}- and in situ analysis. {mu}-XRF allows one to collect elemental and spatially-resolved information in a non-destructive way on major and minor constituents of a variety of materials. However, the main disadvantages of {mu}-XRF are the penetration depth of the X-rays and the fact that only elements and not specific molecular combinations of elements can be detected. As a result {mu}-XRF is often not specific enough to identify the pigments within complex mixtures. Confocal Raman microscopy ({mu}-RS) can offer a surplus as molecular information can be obtained from single pigment grains. However, in some cases the presence of a strong fluorescence background limits the applicability. In this paper, the concrete analytical possibilities of the combined PRAXIS device are evaluated by comparing the results on an illuminated sheet of parchment with the analytical information supplied by synchrotron radiation {mu}-X-ray diffraction (SR {mu}-XRD), a highly specific technique.

    We report on a search for B0(s) --> mu+ mu- and B0(d) --> mu + mu- decays in pp collisions at square root(s) = 1.96 TeV using 364 pb(-1) of data collected by the CDF II detector at the Fermilab Tevatron Collider. After applying all selection requirements, we observe no candidates inside the B0(s) or B0(d) mass windows. The resulting upper limits on the branching fractions are B(B0(s) --> mu+ mu-) mu+ mu-) < 3.9 x 10(-8) at 90% confidence level.

  17. Development of 700 pps high-duty-cycle line-type pulse modulator

    The high-duty-cycle line-type pulse modulator has been developed to drive the 5.5 MW S-band klystron at the 700 pps maximum repetition-rate and the 14 {mu}sec flat-top pulse-width. To keep an enough recovery time to the thyratron-tube, the command charging scheme was adopted. To do this, a charging SCR-bank has been developed, which is capable of handling the peak charging current of 50 A. The system achieved the world wide highest average output-power of 205 kW. Two modulators have been installed in a new high-duty-cycle electron linear accelerator, which has been started its business operation in March 1996 as an electron-beam-sterilization facility.

    The first measurements of the forward-backward asymmetry of the dimuon pair ($A_{FB}$), the triple-product asymmetry ($A_{2\\phi}$), and the charge-parity-conjugation asymmetry ($A_{CP}$), in $D^0\\to\\pi^+\\pi^-\\mu^+\\mu^-$ and $D^0\\to K^+K^-\\mu^+\\mu^-$ decays are reported. They are performed using data from proton-proton collisions collected with the LHCb experiment from 2011 to 2016, corresponding to a total integrated luminosity of 5 fb$^{-1}$. The asymmetries are measured to be \\begin{align*} A_{FB}(D^0\\to\\pi^+\\pi^-\\mu^+\\mu^-) &= (\\phantom{-}3.3\\pm3.7\\pm0.6)\\%,\\\\ A_{2\\phi}(D^0\\to\\pi^+\\pi^-\\mu^+\\mu^-)&= (-0.6\\pm3.7\\pm0.6)\\%,\\\\ A_{CP}(D^0\\to\\pi^+\\pi^-\\mu^+\\mu^-) &= (\\phantom{-}4.9\\pm3.8\\pm0.7)\\%,\\\\ A_{FB}(D^0\\to K^+K^-\\mu^+\\mu^-) &= (0\\pm11\\pm2)\\%,\\\\ A_{2\\phi}(D^0\\to K^+K^-\\mu^+\\mu^-)&= (9\\pm11\\pm1)\\%,\\\\ A_{CP}(D^0\\to K^+K^-\\mu^+\\mu^-) &= (0\\pm11\\pm2)\\%, \\end{align*} where the first uncertainty is statistical and the second systematic.

    This brief presents an ultra-wideband pulse generator topology featuring adaptive control of power spectral density for a broad range of applications with different data rate requirements. The adaptivity is accomplished by employing a limited monocycle precharge approach to control the energy use...... for validation. The measured results show that the pulse generator can be used for a wide pulse repetition rate range from 100 Mpps to 1 Gpps. In addition, the pulse generator consumes 0.76 pJ/pulse at 1 Gpps, equivalent to 760 μW and has a compact size of 0.09 mm2....

    An efficient acousto-optic Q-switched laser operation of Yb:(LuxGd1-x)3Ga5O12 (x = 0.062) (Yb:LGGG) crystal is demonstrated, producing stable pulses with repetition rate ranging from 1 to 20 kHz. Under the absorbed pump power of 8.75 W, the maximum average output power of 3.26 W is obtained at the pulse repletion rate of 1 kHz, corresponding to the slope efficiency as high as 52%. The pulse width of 14.5 ns is achieved with the pulse energy and peak power of 3.26 mJ and 225 kW, respectively. It indicates great potential of Yb:LGGG crystal for generating pulsed lasers.

  1. B^0_s -> mu^+ mu^- gamma decay in LHCb

    CERN Multimedia

    Dettori, F

    2009-01-01

    Being FCNC processes, the B^0_s -> mu^+ mu^- and B^0_s -> mu^+ mu^- gamma decays are suppressed in the Standard Model, but can be highly enhanced in case of New Physics which can come as new particles flowing in the loops. Both these decays occur with a branching ratio in the SM at the level of 10?9: the Bs -> mu^+ mu^- gamma in fact is suppressed by having one more vertex but enhanced by removing the elicity suppression. Prospects for the search of the B^0_s -> mu^+ mu^- gamma decay in LHCb are presented in this poster.

    A search for the decays B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -} and B{sup 0}{yields}{mu}{sup +}{mu}{sup -} is performed with 0.37 fb{sup -1} of pp collisions at {radical}(s)=7 TeV collected by the LHCb experiment in 2011. The upper limits on the branching fractions are B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -})<1.6 Multiplication-Sign 10{sup -8} and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -})<3.6 Multiplication-Sign 10{sup -9} at 95% confidence level. A combination of these results with the LHCb limits obtained with the 2010 dataset leads to B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -})<1.4 Multiplication-Sign 10{sup -8} and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -})<3.2 Multiplication-Sign 10{sup -9} at 95% confidence level.

  5. Symmetry issues in a class of ion beam targets using short direct drive pulses

    International Nuclear Information System (INIS)

    Mark, J.W.K.; Lindl, J.D.

    1986-01-01

    We address a class of modified ion beam targets where the symmetry issues are ameliorated in the regime of short bursts of direct drive pulses. Short pulses are here defined so that the fractional change in target radii of peak beam energy deposition are assumed to be small (during each such direct drive burst with a fixed beam focal radius). This requirement is actually not stringent on the temporal pulse-length. In fact we show an explicit example where this can be satisfied by a ≥ 60 ns direct drive pulse-train. A new beam placement scheme is used which systematically eliminated low order spherical harmonic asymmetries. The residual asymmetries of such pulses are studied with both simple model and numerical simulations

  6. Search for the lepton flavour violating decay $\\tau^-\\to\\mu^+\\mu^-\\mu^-$ with the LHCb detector

    2014-01-01

    A search for the lepton flavour violating decay $\\tau^- \\rightarrow \\mu^+ \\mu^- \\mu^-$ is presented. The analysis is performed using a data sample corresponding to $1.0 ~\\mathrm{fb}^{-1}$ of integrated luminosity, collected with the LHCb detector during 2011. No evidence for signal has been found and a limit has been set on the branching franction at $90\\%$ C.L.: $\\mathcal{B}(\\tau^- \\rightarrow \\mu^+ \\mu^- \\mu^-) < 8.0 \\cdot 10^{-8}$.

    A search for the rare decays $B^0_s \\to\\mu^+\\mu^-$ and $B^0 \\to\\mu^+\\mu^-$ is performed at the LHCb experiment. The data analysed correspond to an integrated luminosity of 1 fb$^{-1}$ of $pp$ collisions at a centre-of-mass energy of 7 TeV and 2 fb$^{-1}$ at 8 TeV. An excess of $B^0_s \\to\\mu^+\\mu^-$ signal candidates with respect to the background expectation is seen with a significance of 4.0 standard deviations. A time-integrated branching fraction of ${\\cal B}(B^0_s \\to\\mu^+\\mu^-) = (2.9^{+1.1}_{-1.0})\\times 10^{-9}$ is obtained and an upper limit of ${\\cal B}(B^0 \\to\\mu^+\\mu^-) < 7.4\\times 10^{-10}$ at 95% confidence level is set. These results are consistent with the Standard Model expectations.

    The decays $B_c^+ \\to J/\\psi D_s^+$ and $B_c^+ \\to J/\\psi D_s^{*+}$ are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 fb$^{-1}$ and 20.6 fb$^{-1}$ of $pp$ collisions collected at centre-of-mass energies $\\sqrt{s} = 7$ TeV and 8 TeV, respectively. Signal candidates are identified through $J/\\psi\\to\\mu^+\\mu^-$ and $D_s^{(*)+}\\to\\phi\\pi^+(\\gamma/\\pi^0)$ decays. With a two-dimensional likelihood fit involving the $B_c^+$ reconstructed invariant mass and an angle between the $\\mu^+$ and $D_s^+$ candidate momenta in the muon pair rest frame, the yields of $B_c^+ \\to J/\\psi D_s^+$ and $B_c^+ \\to J/\\psi D_s^{*+}$, and the transverse polarisation fraction in $B_c^+ \\to J/\\psi D_s^{*+}$ decay are measured. The transverse polarisation fraction is determined to be $\\Gamma_{\\pm\\pm}(B_c^+ \\to J/\\psi D_s^{*+})/\\Gamma(B_c^+ \\to J/\\psi D_s^{*+}) = 0.38 \\pm 0.23 \\pm 0.07$, and the derived ratio of the branching fractions of the two modes is $\\mathcal{B}_{B_c^+ \\to J/...

    2010-01-01

    We report on numerical and experimental characterization of the performance of a fiber link optimized for the delivery of sub-100-fs laser pulses at 1550 nm over several meters of fiber. We investigate the power handling capacity of the link, and demonstrate all-fiber delivery of 1-nJ pulses over...... a distance of 5.3 m. The fiber link consists of dispersion-compensating fiber (DCF) and standard single-mode fiber. The optical pulses at different positions in the fiber link are measured using frequency-resolved optical gating (FROG). The results are compared with numerical simulations of the pulse...... propagation based on the generalized nonlinear Schrödinger equation. The high input power capacity of the fiber link allows the splitting and distribution of femtosecond pulses to an array of fibers with applications in multi-channel fiber-coupled terahertz time-domain spectroscopy and imaging systems. We...

    Highlights: ► A double-fed control system is designed for J-TEXT 100 MVA pulse generator unit. ► The double-fed system can control the motor speed and reactive power individually. ► Experiment on a prototype motor shows a good control result. -- Abstract: The 100 MVA pulse generator unit is the main power supply of J-TEXT. This unit supplies energy for the toroidal coil, the ohmic heat coil and the divertor coil, with the maximum stored energy 185 MJ. For the difference of grid frequency between China and USA, the rotational speed and stored energy of this unit are less than the designed value. A double-fed control system for the unit is designed to raise them. This double-fed system has applied a control method using a rotational reference frame oriented by stator flux. With this control system, the speed and reactive power of motor could be controlled individually. Experiments on a prototype motor show a good control result

    We investigate hollow-core fibers for fiber delivery of high power ultrashort laser pulses. We use numerical techniques to design an anti-resonant hollow-core fiber having one layer of non-touching tubes to determine which structures offer the best optical properties for the delivery of high power...... picosecond pulses. A novel fiber with 7 tubes and a core of 30 mu m was fabricated and it is here described and characterized, showing remarkable low loss, low bend loss, and good mode quality. Its optical properties are compared to both a 10 mu m and a 18 mu m core diameter photonic band gap hollow......-core fiber. The three fibers are characterized experimentally for the delivery of 22 picosecond pulses at 1032nm. We demonstrate flexible, diffraction limited beam delivery with output average powers in excess of 70W. (C) 2016 Optical Society of America...

    2011-08-01

    Sub-250-fs pulses with energies of up to 650 nJ and peak powers up to 2.07 MW were generated from a cavity-dumped optical parametric oscillator, synchronously-pumped at 15.3 MHz with sub-400-fs pulses from an Yb:fiber laser. The average beam quality factor of the dumped output was M2 ~1.2 and the total relative-intensity noise was 8 mdBc, making the system a promising candidate for ultrafast laser inscription of infrared materials.

  16. Optimization And Single-Shot Characterization Of Ultrashort Thz Pulses From A Laser Wakefield Accelerator

    We present spatiotemporal characterization of μJ-class ultrashort THz pulses generated from a laser wakefield accelerator (LWFA). Accelerated electrons, resulting from the interaction of a high-intensity laser pulse with a plasma, emit high-intensity THz pulses as coherent transition radiation. Such high peak-power THz pulses, suitable for high-field (MV/cm) pump-probe experiments, also provide a non-invasive bunch-length diagnostic and thus feedback for the accelerator. The characterization of the THz pulses includes energy measurement using a Golay cell, 2D sign-resolved electro-optic measurement and single-shot spatiotemporal electric-field distribution retrieval using a new technique, coined temporal electric-field cross-Correlation (TEX). All three techniques corroborate THz pulses of ∼ 5 μJ, with peak fields of 100's of kV/cm and ∼ 0.4 ps rms duration.

  17. Prospects for measuring the branching ratio of the rare B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay with the ATLAS experiment

    The Large Hadron Collider (LHC) located at the CERN laboratory in Geneva provides p-p collisions at a centre-of-mass energy of {radical}(s)=7 TeV. The study of the rare B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay is among the research topics of ATLAS, one of the main experiments at the LHC. This decay is highly suppressed in the Standard Model of particle physics and may give an indirect evidence for New Physics models. This PhD thesis investigates prospects for measuring the branching ratio of the B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay with the ATLAS experiment. The analysis is based on Monte Carlo data, with p-p collisions generated at a centre-of-mass energy of {radical}(s)=10 TeV. The strategy employed is to calculate the B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} branching ratio relative to the branching ratio of the B{sup +}{yields} J/{psi}({mu}{sup +}{mu}{sup -})K{sup +} decay. The dominant background channel is the b anti b{yields}{mu}{sup +}{mu}{sup -}X combinatorial background. True B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -} decay candidates are separated from the much larger amount of combinatorial background events using several discriminating quantities. Upper limits on the B{sup 0}{sub s} {yields} {mu}{sup +}{mu}{sup -} branching ratio are computed using a Bayesian and a frequentist method. The expected precision of the branching ratio measurement is estimated for different values of the integrated luminosity. An expected upper limit on the branching ratio is computed to BR(B{sup 0}{sub s}{yields}{mu}{sup +}{mu}{sup -})<3.8 x 10{sup -8} at a 95% confidence level for 1 fb{sup -1}. The precision of the ATLAS measurement of the branching ratio will reach a level compatible with the best current measurements with about 2-5 fb{sup -1} of data.

  18. From a {nu} factory to {mu} super + mu super {minus} Colliders

    An important feature of a {mu}-storage ring {nu}-source is that it can be extended to the possibility of a future high-energy muon collider. The neutrino source provides a useful physics device that initiates key technologies required for future {mu}{sup +}-{mu}{sup {minus}} Colliders, but with much less demanding parameter requirements. These technologies include high-intensity {mu}-production, {mu}-capture, {mu}-cooling, {mu}-acceleration and multiturn {mu} storage rings. {mu}{sup +}-{mu}{sup {minus}} colliders require a similar number of muons, but they require that the muons be cooled to a much smaller phase space and formed into a small number of bunches, and both positive and negative bunches must be simultaneously captured. These differences are discussed, and the extension of the {nu}-source to {mu}{sup +}-{mu}{sup {minus}} collider specifications is described.

    The isospin asymmetries of $B \\to K^{(*)}\\mu^+\\mu^-$ decays and the partial branching fractions of $B^0 \\to K^0\\mu^+\\mu^-$ and $B^+ \\to K^{*+}\\mu^+\\mu^-$ are measured as a function of the di-muon mass squared $q^2$ using an integrated luminosity of 1.0 fb$^{-1}$ collected with the LHCb detector. The $B \\to K\\mu^+\\mu^-$ isospin asymmetry integrated over $q^2$ is negative, deviating from zero with over 4 $\\sigma$ significance. The $B \\to K^{*}\\mu^+\\mu^-$ decay measurements are consistent with the Standard Model prediction of negligible isospin asymmetry. The observation of the decay $B^0 \\to K^0_{\\rm\\scriptscriptstyle S}\\mu^+\\mu^-$ is reported with 5.7 $\\sigma$ significance. Assuming that the branching fraction of $B^0 \\to K^0\\mu^+\\mu^-$ is twice that of $B^0 \\to K^0_{\\rm\\scriptscriptstyle S}\\mu^+\\mu^-$, the branching fractions of $B^0 \\to K^0\\mu^+\\mu^-$ and $B \\to K^{*+}\\mu^+\\mu^-$ are found to be ($0.31^{+0.07}_{-0.06}) \\times 10^{-6}$ and ($1.16\\pm0.19) \\times 10^{-6}$, respectively.

    The production of $J/\\psi$ and $\\Upsilon$ mesons in $pp$ collisions at $\\sqrt{s}$ = 8 TeV is studied with the LHCb detector. The $J/\\psi$ and $\\Upsilon$ mesons are reconstructed in the $\\mu^+ \\mu^-$ decay mode and the signal yields are determined to fit to the $\\mu^+ \\mu^-$ invariant mass distributions. The analysis is performed in the rapidity range 2.0 < $y$ < 4.5 and transverse momentum range 0 < $pT$ < 14(15) GeV/$c$ of the $J/\\psi(\\Upsilon)$ mesons. The $J/\\psi$ and $\\Upsilon$ production cross-sections and the fractions of the $J/\\psi$ mesons from $b$-hadron decays are measured as a function of the meson $pT$ and $y$.

    We demonstrate laser driven acceleration of electrons at 1 kHz repetition rate with pC charge above 1MeV per shot using required for relativistic self-focusing low enough for mJ scale laser pulses to self- focus and drive strong wakefields. Experiments and particle-in-cell simulations show that optimal drive pulse duration and chirp for maximum electron bunch charge and energy depends on the target gas species. High repetition rate, high charge, and short duration electron bunches driven by very modest pulse energies constitutes an ideal portable electron source for applications such as ultrafast electron diffraction experiments and high rep. rate γ-ray production. This work is supported by the US Department of Energy, the National Science Foundation, and the Air Force Office of Scientific Research.

    Burns cause changes in the anatomical structure of the skin associated with trauma. The severity of the burn injury is divided into first, second and third-degree burns. The third-degree burns have been a major focus of research in search of more conservative treatments and faster results in repair for a functional and cosmetically acceptable. The conventional treatment is the use of topical natural or synthetic skin graft. An alternative therapy is the laser ablation process for burned tissue necrosis removal due to the no mechanical contact, fast application and access to difficult areas. The purpose of this study is to evaluate the feasibility of using high intensity femtosecond lasers as an adjunct treatment of burned patients. For this study, 65 Wistar rats were divided into groups of five animals: healthy skin, burned skin, two types of treatment (surgical debridement or femtosecond laser ablation) and four different times in the healing process monitoring. Three regions of the back of the animals were exposed to steam source causing third-degree burn. On the third day after the burn, one of the regions was ablated with high intensity ultrashort laser pulses ({lambda} = 785 nm, 90 fs, 2 kHz and 10 {mu}J/ pulse), the other received surgical debridement, and the last was considered the burn control. The regions were analyzed by optical coherence tomography (OCT), histology, attenuated total reflectance infrared spectroscopy using Fourier transform ({mu}-ATR-FTIR), two-photon excitation fluorescence microscopy (TPEFM) and second harmonic generation technique (SHG) on days 3, 5, 7 and 14 pos-treatments. The results showed that with the laser irradiation conditions used it was possible to remove debris from third degree burn. The techniques used to characterize the tissue allowed to verify that all treatments promoted wound healing. On the fourteenth day, the regeneration curve showed that the attenuation coefficient of laser ablated tissue converges to the values

    The GRENOUILLE traces of FLAME Probe line pulses (60mJ, 10mJ after compression, 70fs, 1cm FWHM, 10Hz) were acquired in the FLAME Front End Area (FFEA) at the Laboratori Nazionali di Frascati (LNF), Instituto Nazionale di Fisica Nucleare (INFN). The complete characterization of the laser pulse parameters was made using a new algorithm: GRenouille/FrOG (GROG). A characterization with a commercial algorithm, QUICKFrog, was also made. The temporal and spectral parameters came out to be in great agreement for the two kinds of algorithms. In this experimental campaign the Probe line of FLAME has been completely characterized and it has been showed how GROG, the developed algorithm, works as well as QuickFrog algorithm with this type of pulse class.

    A search for the rare decays $B^0_s \\to \\mu^+\\mu^-$ and $B^0 \\to \\mu^+\\mu^-$ is performed using data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples comprise 1.1 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s}$ = 8 TeV and 1.0 fb$^{-1}$ at $\\sqrt{s}$=7 TeV. We observe an excess of $B^0_s \\to \\mu^+ \\mu^-$ candidates with respect to the background expectation. The probability that the background could produce such an excess or larger is 5.3 x 10$^{-4}$ corresponding to a signal significance of 3.5 standard deviations. A maximum-likelihood fit gives a branching fraction of $BR(B^0_s \\to \\mu^+ \\mu^-) = (3.2^{+1.5}_{-1.2})$ x $10^{-9}$, where the statistical uncertainty is 95% of the total uncertainty. This result is in agreement with the Standard Model expectation. The observed number of $B^0 \\to \\mu^+ \\mu^-$ candidates is consistent with the background expectation, giving an upper limit of $BR(B^0 \\to \\mu^+ mu^-) < 9.4$ x $10^{-10}$ at 95% confidence level...

    A search for the $D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-$ decay, where the muon pair does not originate from a resonance, is performed using proton-proton collision data corresponding to an integrated luminosity of $1.0\\mathrm{fb}^{-1}$ recorded by the LHCb experiment at a centre-of-mass energy of $7\\mathrm{TeV}$. No signal is observed and an upper limit on the relative branching fraction with respect to the resonant decay mode $D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)$, under the assumption of a phase-space model, is found to be \\begin{align} \\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-)/\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)) < 0.96\\\\ \\end{align} at the $90\\%$ confidence level. The upper limit on the absolute branching fraction is evaluated to be $\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-) < 5.5 \\, \\times 10^{-7}$ at 90% confidence level. This is the most stringent to date.

    Study of J/{psi} production from the data recorded during 1991 with the L3 detector. The J/{psi} is identified by its decay J/{psi} - {mu}''+{mu}''- in the invariant mass spectrum of two muons. With our analysis results we have calculated the branching ratios Br(Z''0 -J/{psi} + X) = (3.4 +- 0.7 (statistic)+- 0.2 (systematic)) x 10{sup 3} and Br(b-> J/{psi}+ X) = (1.20 +- 0.25 (statistic) +0.15 (systematic))%.

    We present the first blind interferometric detection and imaging of a millisecond radio transient with an observation of transient pulsar J0628+0909. We developed a special observing mode of the Karl G. Jansky Very Large Array to produce correlated data products (i.e., visibilities and images) on a timescale of 10 ms. Correlated data effectively produce thousands of beams on the sky that can localize sources anywhere over a wide field of view. We used this new observing mode to find and image pulses from the rotating radio transient (RRAT) J0628+0909, improving its localization by two orders of magnitude. Since the location of the RRAT was only approximately known when first observed, we searched for transients using a wide-field detection algorithm based on the bispectrum, an interferometric closure quantity. Over 16 minutes of observing, this algorithm detected one transient offset roughly 1' from its nominal location; this allowed us to image the RRAT to localize it with an accuracy of 1.''6. With a priori knowledge of the RRAT location, a traditional beam-forming search of the same data found two lower significance pulses. The refined RRAT position excludes all potential multiwavelength counterparts, limiting its optical luminosity to L i ' 31 erg s –1 and disfavoring source models with luminous neutron stars.

    The well-known Giudice-Masiero mechanism explains the presence of a {mu} term of the order of the gravitino mass, but does not explain why the holomorphic mass term is absent in the superpotential. We discuss anomaly-free discrete symmetries which are both compatible with SU(5) unification of matter and the Giudice-Masiero mechanism, i.e. forbid the {mu} term in the superpotential while allowing the necessary Kaehler potential term. We find that these are Z{sup R}{sub M} symmetries with the following properties: (i) M is a multiple of four; (ii) the Higgs bilinear H{sub u} H{sub d} transforms trivially; (iii) the superspace coordinate {theta} has charge M/4 and, accordingly, the superpotential has charge M/2; (iv) dimension five proton decay operators are automatically absent. All Z{sup R}{sub M} symmetries are anomaly-free due to a non-trivial transformation of a Green-Schwarz axion, and, as a consequence, a holomorphic {mu} term appears at the non-perturbative level. There is a unique symmetry that is consistent with the Weinberg operator while there is a class of Z{sup R}{sub M} symmetries which explain suppressed Dirac neutrino masses.

    In a search for back-decay gamma rays from the shape isomer in 238 U following mu-minus capture, no candidates have been found with yields greater than 2 percent of the muon stoppings. The intensities of the gamma rays are insufficient to permit definitive lifetime measurements of individual peaks; however, for 500-keV energy ranges of gamma ray pulses, lifetimes have been determined that give results consistent with recent electron lifetime measurements.

    Metal atoms in solid and liquid helium-4 have attracted some interest either as a way to keep the atoms in a weakly perturbing matrix, or using them as a probe for the helium host medium. Laser sputtering with nanosecond pulsed lasers is the most often used method for atom production, resulting however in a substantial perturbation of the matrix. We show that a much weaker perturbation can be obtained by using femtosecond laser pulses with energy as low as 10 μJ. As an unexpected benefit, the atomic density produced is much higher.

    We have developed conceptual designs of two petawatt-class pulsed-power accelerators: Z 300 and Z 800. The designs are based on an accelerator architecture that is founded on two concepts: single-stage electrical-pulse compression and impedance matching [Phys. Rev. ST Accel. Beams 10, 030401 (2007)]. The prime power source of each machine consists of 90 linear-transformer-driver (LTD) modules. Each module comprises LTD cavities connected electrically in series, each of which is powered by 5-G...

    We describe the production of 2.2-mJ, ∼6 optical-cycle-long mid-infrared laser pulses with a carrier wavelength of 2.05 μm in a two-stage β-BaB 2 O 4 nondegenerate optical parametric amplifier design with a mixed phase matching scheme, which is pumped by a standard Ti:sapphire chirped-pulse amplification system. It is demonstrated that relatively high pulse energies, short pulse durations, high stability, and excellent beam profiles can be obtained using this simple approach, even without the use of optical parametric chirped-pulse amplification

  1. Generation of frequency-chirped optical pulses with felix

    Frequency-chirped optical pulses have been produced in the picosecond regime by varying the energy of the electron beam on a microsecond time scale. These pulses were then compressed close to their bandwidth limit by an external pulse compressor. The amount of chirp can be controlled by varying the sweep rate on the electron beam energy and by cavity desynchronisation. To examine the generated chirp we used the following diagnostics: a pulse compressor, a crossed beam autocorrelator, a multichannel electron spectrometer and multichannel optical spectrometer. The compressor is build entirely using reflective optics to permit broad band operation. The autocorrelator is currently operating from 6 {mu}m to 30 {mu}m with one single crystal. It has been used to measure pulses as short as 500 fs. All diagnostics are evacuated to prevent pulse shape distortion or pulse lengthening caused by absorption in ambient water vapour. Pulse length measurements and optical spectra will be presented for different electron beam sweep rates, showing the presence of a frequency chirp. Results on the compression of the optical pulses to their bandwidth limit are given for different electron sweep rates. More experimental results showing the dependence of the amount of chirp on cavity desynchronisation will be presented.

    The isospin asymmetries of $B \\to K\\mu^+\\mu^-$ and $B \\to K^{*}\\mu^+\\mu^-$ decays and the partial branching fractions of the $B^0 \\to K^0\\mu^+\\mu^-$, $B^+ \\to K^+\\mu^+\\mu^-$ and $B^+ \\to K^{*+}\\mu^+\\mu^-$ decays are measured as functions of the dimuon mass squared, $q^2$. The data used correspond to an integrated luminosity of 3 fb$^{-1}$ from proton-proton collisions collected with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV in 2011 and 2012, respectively. The isospin asymmetries are both consistent with the Standard Model expectations. The three measured branching fractions, while individually consistent, all favour lower values than their respective Standard Model predictions.

  3. Development of high damage threshold optics for petawatt-class short-pulse lasers

    The authors report laser-induced damage threshold measurements on pure and multilayer dielectrics and gold-coated optics at 1053 and 526 nm for pulse durations, τ, ranging from 140 fs to 1 ns. Damage thresholds of gold coatings are limited to 500 mJ/cm 2 in the subpicosecond range for 1053-nm pulses. In dielectrics, qualitative differences in the morphology of damage and a departure from the diffusion-dominated τ1/2 scaling indicate that damage results from plasma formation and ablation for τ≤10 ps and from conventional melting and boiling for τ>50 ps. A theoretical model based on electron production via multiphoton ionization, Joule heating, and collisional (avalanche) ionization is in quantitative agreement with both the pulsewidth and wavelength scaling of experimental results

    A search for the rare decays $B_s \\rightarrow \\mu^+ \\mu^-$ and $B_d \\rightarrow \\mu^+ \\mu^-$ is performed with data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples comprise 1.1 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s} = 8$ TeV and 1.0 fb$^{-1}$ at $\\sqrt{s}=7$ TeV. We observe an excess of $B_s \\rightarrow \\mu^+ \\mu^-$ candidates with respect to the background expectation. The probability that the background could produce such an excess or larger is $5.3\\times 10^{-4}$ corresponding to a signal significance of 3.5 standard deviations. A maximum-likelihood fit gives a branching fraction of $ {\\cal B} (B_s \\rightarrow \\mu^+ \\mu^-)$ = $(3.2^{\\,+1.5}_{\\,-1.2}) \\times 10^{-9}$, where the statistical uncertainty is 95 % of the total uncertainty. This result is in agreement with the Standard Model expectation. The observed number of $B^0 \\rightarrow \\mu^+ \\mu^-$ candidates is consistent with the background expectation, giving an upper limit of ${\\cal B}(B...

    We report the detection of {gamma}-ray pulsations ({ge}0.1 GeV) from PSR J2229+6114 and PSR J1048-5832, the latter having been detected as a low-significance pulsar by EGRET. Data in the {gamma}-ray band were acquired by the Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope, while the radio rotational ephemerides used to fold the {gamma}-ray light curves were obtained using the Green Bank Telescope, the Lovell telescope at Jodrell Bank, and the Parkes Telescope. The two young radio pulsars, located within the error circles of the previously unidentified EGRET sources 3EG J1048-5840 and 3EG J2227+6122, present spin-down characteristics similar to the Vela pulsar. PSR J1048-5832 shows two sharp peaks at phases 0.15 {+-} 0.01 and 0.57 {+-} 0.01 relative to the radio pulse confirming the EGRET light curve, while PSR J2229+6114 presents a very broad peak at phase 0.49 {+-} 0.01. The {gamma}-ray spectra above 0.1 GeV of both pulsars are fit with power laws having exponential cutoffs near 3 GeV, leading to integral photon fluxes of (2.19 {+-} 0.22 {+-} 0.32) x 10{sup -7} cm{sup -2} s{sup -1} for PSR J1048-5832 and (3.77 {+-} 0.22 {+-} 0.44) x 10{sup -7} cm{sup -2} s{sup -1} for PSR J2229+6114. The first uncertainty is statistical and the second is systematic. PSR J1048-5832 is one of the two LAT sources which were entangled together as 3EG J1048-5840. These detections add to the growing number of young {gamma}-ray pulsars that make up the dominant population of GeV {gamma}-ray sources in the Galactic plane.

    Fast ignition (FI) is a form of inertial confinement fusion in which the ignition step and the compression step are separate processes resulting in a reduction of the symmetry requirement for hot spot generation. One of the problems of FI so far are the accessibility of an ignition laser pulse into the assembled core in which the driver energy is converted into relativistic electrons produced in the laser-plasma interaction. We have experimentally demonstrated that a tailored-pulse-assembled core with a diameter of 70 μ m, originally a deuterated polystyrene spherical shell of 500 μ m diameter, is flashed by directly counter irradiating 0.8 J/110 fs laser pulses [Y. MORI et al., PRL 2016]. This result indicates that once the assembled core is squeezed into the target center, the heating lasers can access the core's; edges and deposit their energy into the core. In this talk, we will discuss the heating effects in relation to formation of the assembled core.

    The flavour changing neutral current decays can be interesting probes for searching for new physics. Angular distributions of $b \\to s \\ell^+ \\ell^-$ transition processes of both $\\mathrm{B}^0 \\to \\mathrm{K}^{*0} \\mu^ +\\mu^-$ and $\\mathrm{B}^{+} \\to \\mathrm{K}^{+} \\mu^+\\mu^-$ are studied using a sample of proton-proton collisions at $\\sqrt{s} = 8~\\mathrm{TeV}$ collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $20.5~\\mathrm{fb}^{-1}$. Angular analyses are performed to determine $P_1$ and $P_5'$ angular parameters for $\\mathrm{B}^0 \\to \\mathrm{K}^{*0} \\mu^ +\\mu^-$ and $A_{FB}$ and $F_{H}$ parameters for $\\mathrm{B}^{+} \\to \\mathrm{K}^{+} \\mu^+\\mu^-$, all as functions of the dimuon invariant mass squared. The $P_5'$ parameter is of particular interest due to recent measurements that indicate a potential discrepancy with the standard model. All the measurements are consistent with the standard model predictions. Efforts with more channels and more coming data will be con...

    Exclusive J/psi and psi(2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be sigma(pp -> J/psi(->mu+mu-))(2.0 mu +/-) <4.5) = 307 +/- 21

  10. J/psi production in pp collisions from ALICE

    CERN. Geneva

    2012-01-01

    The ALICE experiment studied J/psi production in the mu+mu- and e+e- decay channels. Inclusive cross sections were measured at both forward and central rapidity down to zero transverse momentum. The results are compared with NRQCD calculations and, for the pp sample collected at sqrt(s)=2.76 TeV, are used as a reference for the determination of nuclear effects on J/psi production in Pb-Pb. At central rapidity, the fraction of J/psi coming from B-decays has been evaluated down to p_T=1.3 GeV/c. In addition, the J/psi yield has been found to linearly increase as a function of the charged hadron multiplicity produced in the collision. Finally, the first LHC results on J/psi polarization, an essential observable for the understanding of the production mechanisms and for theory comparisons, will be presented.

    We report on the first 180 days of Rossi X-Ray Timing Explorer observations of the outburst of the black hole candidate IGR J17091-3624. This source exhibits a broad variety of complex light curve patterns including periods of strong flares alternating with quiet intervals. Similar patterns in the X-ray light curves have been seen in the (up to now) unique black hole system GRS 1915+105. In the context of the variability classes defined by Belloni et al. for GRS 1915+105, we find that IGR J17091-3624 shows the {nu}, {rho}, {alpha}, {lambda}, {beta}, and {mu} classes as well as quiet periods which resemble the {chi} class, all occurring at 2-60 keV count rate levels which can be 10-50 times lower than observed in GRS 1915+105. The so-called {rho} class 'heartbeats' occur as fast as every few seconds and as slow as {approx}100 s, tracing a loop in the hardness-intensity diagram which resembles that previously seen in GRS 1915+105. However, while GRS 1915+105 traverses this loop clockwise, IGR J17091-3624 does so in the opposite sense. We briefly discuss our findings in the context of the models proposed for GRS 1915+105 and find that either all models requiring near Eddington luminosities for GRS 1915+105-like variability fail, or IGR J17091-3624 lies at a distance well in excess of 20 kpc, or it harbors one of the least massive black holes known (<3 M{sub Sun }).

    In the first part of this work the inclusive cross section for J/{psi} production in inelastic {radical}(s) = 7 TeV pp collisions has been determined within vertical stroke y vertical stroke < 0.9 and in the decay channel J/{psi} {yields} e{sup +}e{sup -}. The result for the integrated value is: {sigma}{sub J/{psi}}(vertical stroke y vertical stroke < 0.9) = 10.7 {+-} 0.8 (stat.) {+-} 1.4 (syst.) {+-} 0.4 (lumi.) {mu}b. Together with the ALICE measurement in the {mu}{sup +}{mu}{sup -} decay channel at forward rapidities and data from other experiments this result fills the gap at mid-rapidity for a comprehensive measurement of the J/{psi} rapidity distribution. Furthermore, results of the differential analysis as a function of the J/{psi} transverse momentum were presented. Finally the data are shown together with various theoretical predictions representing the current status of the three most common theoretical approaches for the description of quarkonia production: the Color-Singlet Model, the Color-Evaporation Model and NRQCD.

    We present an analysis of angular distributions and correlations of the X(3872) particle in the exclusive decay mode X(3872)-->J/psipi+ pi- with J/psi-->mu+ mu-. We use 780 pb-1 of data from pp[over ] collisions at sqrt[s]=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. We derive constraints on spin, parity, and charge conjugation parity of the X(3872) particle by comparing measured angular distributions of the decay products with predictions for different J(PC) hypotheses. The assignments J(PC)=1++ and 2-+ are the only ones consistent with the data.

    A large-aperture (30-cm) kilojoule-class Nd:glass laser system known as Z-Beamlet has been constructed to perform x-ray radiography of high-energy-density science experiments conducted on the Z facility at Sandia National Laboratories, Albuquerque, New Mexico. The laser, operating with typical pulse durations from 0.3 to 1.5 ns, employs a sequence of successively larger multipass amplifiers to achieve up to 3-kJ energy at 1054 nm. Large-aperture frequency conversion and long-distance beam transport can provide on-target energies of up to 1.5 kJ at 527 nm

    Exclusive $J/\\psi$ and $\\psi(2S)$ vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be \\begin{equation*} \\sigma_{pp\\rightarrow J/\\psi (\\rightarrow \\mu^{+} \\mu^{-})} (2.0 <\\eta_{\\mu^{\\pm}}< 4.5) = 307 \\pm 21 \\pm 36~\\text{pb}, \\end{equation*} \\begin{equation*} \\sigma_{pp\\rightarrow \\psi(2S) (\\rightarrow \\mu^{+} \\mu^{-})} (2.0 <\\eta_{\\mu^{\\pm}}< 4.5) = 7.8 \\pm 1.3 \\pm 1.0~\\text{pb}, \\end{equation*} where the first uncertainties are statistical and the second are systematic. The measurements are found to be in good agreement with results from previous experiments and theoretical predictions. The $J/\\psi$ photoproduction cross-section has been measured as a function of the photon-proton centre-of-mass energy. The results are consistent with measurements obtained at HERA and confirm a similar power law behaviour for the photoproduction cross-se...

    A series of 3,8-diazabicyclo (3.2.1) octanes (DBO) (1) substituted at the nitrogen atoms by acyl and aralkenyl groups, were tested in in vitro binding assays towards mu and delta opioid receptors. The most representative terms (1a, 1d, 1g, 1j,) were also evaluated for the analgesic potency in vivo by the hot plate method. Among the compounds tested the most potent was the p.nitrocinnamyl DBO (1d) which displayed a mu/delta selectivity and an analgesic activity respectively 25 and 17 fold those of morphine. On the contrary, the m.hydroxycinnamyl DBO (1g) was markedly less active as agonist than the parent 1a, thus suggesting that structure 1 interacts with opioid receptors in a different fashion than morphine. Compound 1j isomer of 1a which is provided with high mu affinity, but lower analgesic potency, was found to possess a mixed agonist-antagonist activity.

    A search for the rare decay $D^0 \\to \\mu^+ \\mu^-$is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb$^{-1}$, of $pp$ collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The observed number of events is consistent with the background expectations and corresponds to an upper limit of ${\\cal B}(D^0 \\to \\mu^+ \\mu^-) < 6.2(7.6) \\times 10^{-9}$ at 90% (95%) confidence level. This result represents an improvement of more than a factor twenty with respect to previous measurements.

    Very high speed electronics technology is indispensable for the creation of industrial base technology which supports high grade informatizing in the 21st century. The state of light and electronics is controlled in the femto-second time domain. As to the development of femto-second light pulse generation/transmission technology, mode synchronous semiconductor laser was manufactured using the strain quantum well structure aiming at heightening profit, and the repeated frequency, 166GHz, was achieved. Relating to the pulse compression element, exciton photonic band was newly designed. A technology of coding was also studied. As to the development of technology of femto-second light pulse control/distribution, shortening of the wavelength down to 1.5{mu}m and a possibility of femto-second domain high speed response were indicated by the combined double quantum well structure. The quantitative measurement of spin relaxation characteristics was successfully made. By the Mach-Zehnder light switch, obtained was the world`s fastest light switching characteristic. To realize the femto-second class very high speed element, conditions were grasped on the crystal growth of Sb based ultra thin films operating in the 1.5{mu}m zone by studying the quantum well using transition among sub-bands. 242 refs., 280 figs., 12 tabs.

    A new type of pulse power system has been developed to obtain an efficient highly repetitive pulse-power generation. The system is constructed of a double pulse circuit (1st stage), step-up transformer and Blumlein pulse forming line (BL) and can generate high power pulse of 600 kV, 24 kA, 60 ns. In the system, discharge gap switches are replaced by magnetic switches. In addition, instead of Marx generator, a step-up transformer is utilized to generate high voltage pulse. The system is tested under the double pulse mode where two 1st stage capacitors are connected in parallel and switched with a interval of T{sub d}. The minimum value of T{sub d} is limited by the recovery of 1st stage gap switches and at T{sub d} {>=} 500 {mu}s (equivalent rep-rate of 2 kHz), the system is operated with good reproducibility. To enhance the recovery, magnetic switch is utilized, which enables operation at T{sub d} {>=} 30 {mu}s (equivalent rep-rate of 33 kHz). (author). 7 figs., 7 refs.

  3. UPPER LIMITS ON PULSED RADIO EMISSION FROM THE 6.85 s X-RAY PULSAR XTE J0103-728 IN THE SMALL MAGELLANIC CLOUD

    X-ray pulsations with a 6.85 s period were recently detected in the Small Magellanic Cloud (SMC) and were subsequently identified as originating from the Be/X-ray binary system XTE J0103-728. The recent localization of the source of the X-ray emission has made a targeted search for radio pulsations from this source possible. The detection of pulsed radio emission from XTE J0103-728 would make it only the second system after PSR B1259-63 that is both a Be/X-ray binary and a radio pulsar. We observed XTE J0103-728 in 2008 February with the Parkes 64 m radio telescope soon after the identification of the source of X-ray pulsations was reported in order to search for corresponding radio pulsations. We used a continuous 6.4 hr observation with a 256 MHz bandwidth centered at 1390 MHz using the center beam of the Parkes multibeam receiver. In the subsequent data analysis, which included a folding search, a Fourier search, a fast-folding algorithm search, and a single pulse search, no pulsed signals were found for trial dispersion measures (DMs) between 0 and 800 pc cm -3 . This DM range easily encompasses the expected values for sources in the SMC. We place an upper limit of ∼45 mJy kpc 2 on the luminosity of periodic radio emission from XTE J0103-728 at the epoch of our observation, and we compare this limit to a range of luminosities measured for PSR B1259-63, the only Be/X-ray binary currently known to emit radio pulses. We also compare our limit to the radio luminosities of neutron stars having similarly long spin periods to XTE J0103-728. Since the radio pulses from PSR B1259-63 are eclipsed and undetectable during the portion of the orbit near periastron, repeated additional radio search observations of XTE J0103-728 may be valuable if it is undergoing similar eclipsing and if such observations are able to sample the orbital phase of this system well.

  4. The Small Magellanic Cloud in the far infrared. I. ISO's 170 mu m map and revisit of the IRAS 12-100 mu m data

    The ISOPHOT experiment onboard the ISO satellite generated a complete view of the Small Magellanic Cloud (SMC) at 170 mu m with 1.5 arcmin resolution. The map is analysed using an automated photometry program enabling accurate photometric characterization of the far infrared (FIR) emitting regions. An integrated FIR luminosity of 8.5x 107 Lsun is obtained, leading to a star formation rate of SFRFIR=0.015 Msun/yr. With an average dust temperature of TD, 170/100}=20.5 K>, the total dust mass follows to MD=3.7x105 Msun. In this paper, the sources detected at 170 mu m are compared with those obtainable from the IRAS satellite data. For this purpose, the 12 mu m, 25 mu m, 60 mu m, and 100 mu m IRAS high resolution (HiRes) maps of the SMC are re-examined using the same method. In contrast to former studies, this provides an all-band ISO/IRAS source catalog which is no longer based on eyeball classification, but relies on an algorithm which is capable of automated, repeatable photometry, even for irregular sources. In the mid infrared IRAS bands numerous bright FIR emitting regions in the SMC are detected and classified: 73 sources are found at 12 mu m, 135 at 25 mu m (most of them with Fnu =2.0 Jy. Comparable numbers are found for the two FIR IRAS maps at 60 mu m (384) and 100 mu m (338) with fluxes up to 450 Jy. 70 of the 243 170 mu m sources are assigned a general SED type (``cold'', ``warm'', i.e., 30 K) for the first time. A comparison with earlier IRAS results suggests that many source flux densities in those studies have been under- or overestimated because of non-standardized fitting methods. Many sources with flux densities up to 40 Jy listed in former catalogs cannot be identified in our data.

    We present searches for the rare decay modes D{sup 0} {yields} e{sup +}e{sup -}, D{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}} in continuum e{sup +}e{sup -} {yields} c{bar c} events recorded by the BABAR detector in a data sample that corresponds to an integrated luminosity of 468 fb{sup -1}. These decays are highly GIM suppressed but may be enhanced in several extensions of the Standard Model. Our observed event yields are consistent with the expected backgrounds. An excess is seen in the D{sup 0} {yields} {mu}{sup +}{mu}{sup -} channel, although the observed yield is consistent with an upward background fluctuation at the 5% level. Using the Feldman-Cousins method, we set the following 90% confidence level intervals on the branching fractions: {Beta}(D{sup 0} {yields} e{sup +}e{sup -}) < 1.7 x 10{sup -7}, {Beta}(D{sup 0} {yields} {mu}{sup +}{mu}{sup -}) within [0.6, 8.1] x 10{sup -7}, and {Beta}(D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}) < 3.3 x 10{sup -7}.

    AUTHOR|(INSPIRE)INSPIRE-00400160

    This dissertation documents a study of very rare $B$-meson decays at the LHCb experiment, using data taken during the first experiment run of the Large Hadron Collider (LHC) and during the second experiment run until September 2016. The LHCb experiment was designed to test the Standard Model of particle physics and to search for New Physics effects that go beyond the scope of the Standard Model through the decay of $b$ hadrons produced in high energy proton-proton collisions at the LHC. The measurements described in this dissertation are made using data samples of proton-proton collisions with integrated luminosities of 1.0, 2.0 and 1.4 fb$^{-1}$, collected at centre-of-mass energies of 7, 8 and 13 TeV, respectively. The branching fractions of the very rare $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ decays and the effective lifetime of $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ decays are precisely predicted by the Standard Model and are sensitive to effects from New Physics.

The observed number of candidates is consistent with the background–only hypothesis, yielding an upper limit of $\\cal B(K_S^0 \\to \\mu^+ \\mu^−) < 11(9) × 10^{−9}$ at $95~ (90) \\%$ confidence level. This limit is below the previous measurement by more than a factor of thirty.

    The branching fractions of the decays $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ are highly suppressed in the Standard Model but can be modified by contributions from new physics models. The combined result from the CMS and LHCb Run 1 data for the $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ branching fractions is presented here. The measured results are $\\mathcal{B}(B_{s}^{0} \\to \\mu^{+} \\mu^{-}) = (2.8^{+0.7}_{-0.6})\\times 10^{-9}$ at $6.2 \\sigma$ statistical significance and $\\mathcal{B}(B^{0} \\to \\mu^{+} \\mu^{-}) = (3.9^{+1.6}_{-1.4})\\times 10^{-10}$ at $3.0 \\sigma$ statistical significance, both results are consistent with Standard Model predictions. A brief discussion of the future prospects for the study of $B^{0} \\to \\mu^{+} \\mu^{-}$ and $B_{s}^{0} \\to \\mu^{+} \\mu^{-}$ at the LHCb is also included.

  9. Short-pulse optical parametric chirped-pulse amplification for the generation of high-power few-cycle pulses

    Complete test of publication follows. In the quest for a way to generate ultrashort, high-power, few-cycle laser pulses the discovery of optical parametric amplification (OPA) has opened up to the path towards a completely new regime, well beyond that of conventional laser amplification technology. The main advantage of this parametric amplification process is that it allows for an extremely broad amplification bandwidth compared to any known laser amplifier medium. When combined with the chirped-pulse amplification (CPA) principle (i.e. OPCPA), on one hand pulses of just 10 fs duration and 8 mJ pulse energy have been demonstrated. On the other hand, pulse energies of up to 30 J were also achieved on a different OPCPA system; the pulse duration in this case, however, was 100 fs. In order to combine ultrashort pulse durations (i.e. pulses in the few-cycle regime) with high pulse energies (i.e. in the Joule range) we propose tu pump on OPCPA chain with TW-scale short pulses (100 fs - 1 ps instead of > 100 ps of previous OPCPA systems) delivered by a conventional CPA system. This approach inherently improves the conditions for generating high-power ultrashort pulses using OPCPA in the following ways. Firstly, the short pump pulse duration reduces the necessary stretching factor for the seed pulse, thereby increasing stretching and compression fidelity. Secondly, also due to the shortened pump pulse duration, a much higher contrast is achieved. Finally, the significantly increased pump power makes the use of thinner OPCPA crystals possible, which implies an even broader amplification bandwidth, thereby allowing for even shorter pulses. We carried out theoretical investigations to show the feasibility of such a set-up. Alongside these studies we will also present preliminary experimental results of an OPCPA system pumped by the output of our Ti:Sapphire ATLAS laser, currently delivering 350 mJ in 43 fs.

    A beam pulsing system has been developed for a 12 MV tandem accelerator. The system consists of a pre-acceleration chopper, a klystron buncher and a post-acceleration chopper. The pre-acceleration chopper comprises a slow chopper and a fast travelling-wave chopper. Pulsed beams with widths in the range from 10 ..mu..s to --2 s are obtained with the slow chopper, and the repetition periods can be varied from 70 ..mu..s to 4s. The fast chopper produces ion bursts having widths between 0.05 and 0.8 ..mu..s with a duty factor of --10%. The buncher is operated with the two choppers to obtain beam pulses as narrow as a few nanoseconds. Time-of-flight measurements yielded pulse widths 2-4 ns (FWHM) wide for ions in the mass range 1 <= A <= 28. The ratio of the dark to peak ion current was usually of the order of 10/sup 4/.

    Ratios of the {psi}' over the J/{psi} production cross sections in the dilepton channel for C, Ti and W targets have been measured in 920 GeV proton-nucleus interactions with the HERA-B detector at the HERA storage ring. The {psi}' and J/{psi} states were reconstructed in both the {mu}{sup +}{mu}{sup -} and the e{sup +}e{sup -} decay modes. The measurements covered the kinematic range -0.35{<=}x{sub F}{<=}0.1 with transverse momentum p{sub T}{<=}4.5 GeV/c. The {psi}' to J/{psi} production ratio is almost constant in the covered x{sub F} range and shows a slow increase with p{sub T}. The angular dependence of the ratio has been used to measure the difference of the {psi}' and J/{psi} polarization. All results for the muon and electron decay channels are in good agreement: their ratio, averaged over all events, is R{sub {psi}}{sub '}({mu})/R{sub {psi}}{sub '}(e)=1.00{+-}0.08{+-}0.04. This result constitutes a new, direct experimental constraint on the double ratio of branching fractions, (B'({mu}).B(e))/(B({mu}).B'(e)), of {psi}'' and J/{psi} in the two channels. (orig.)

    The Fermi Large Area Telescope (LAT) data have confirmed the pulsed emission from all six high-confidence gamma-ray pulsars previously known from the EGRET observations. We report results obtained from the analysis of 13 months of LAT data for three of these pulsars (PSR J1057-5226, PSR J1709-4429, and PSR J1952+3252) each of which had some unique feature among the EGRET pulsars. The excellent sensitivity of LAT allows more detailed analysis of the evolution of the pulse profile with energy and also of the variation of the spectral shape with phase. We measure the cutoff energy of the pulsed emission from these pulsars for the first time and provide a more complete picture of the emission mechanism. The results confirm some, but not all, of the features seen in the EGRET data.

    This paper describes the preparation of samples for an experiment to measure the cross-section for 235 U(n,n') 235m U in a fast fission spectrum of neutrons provided by a fast pulsed reactor/critical assembly. Samples of 235m U have been prepared for the calibration of the internal conversion electron detector that is used for the 235m U measurement. Two methods are described for the preparation of 235 mU. The first method used a U-Pu chemical separation based on anion-exchange chromatography and the second method used an alpha recoil collection method. Thin, uniform samples of 235m U+ 235 U were prepared for the experiment using electrodeposition. (author)

    A search for the decay Ks -> pi0 mu+ mu- has been made by the NA48/1 Colaboration at the CERN SPS accelerator. The data were collected during 2002 with a high intensity Ks beam. Six events were found with a background expectation of 0.22^+0.18_0.11 events. Using a vector matrix element and unit form factor, the measured branching ratio is B(Ks -> pi0 mu+ mu-) = [2.9^+1.5_1.2(stat) +- 0.2 (syst)] x 10^9.

  16. Calibration of the ATLAS precision muon chambers and study of the decay {tau} {yields} {mu}{mu}{mu} at the large hadron collider

    Energy Technology Data Exchange (ETDEWEB)

    2010-07-07

    The Large Hadron Collider (LHC) is designed to collide protons at centre-of-mass energies of up to 14 TeV. One of the two general purpose experiments at the LHC is ATLAS, built to probe a broad spectrum of physics processes of the Standard Model of particle physics and beyond. ATLAS is equipped with a muon spectrometer comprising three superconducting air-core toroid magnets and 1150 precision drift tube (MDT) chambers measuring muon trajectories with better than 50 {mu}m position resolution. The accuracy of the space-to-drift-time relationships of the MDT chambers is one of the main contributions to the momentum resolution. In this thesis, an improved method for the calibration of the precision drift tube chambers in magnetic fields has been developed and tested using curved muon track segments. An accuracy of the drift distance measurement of better than 20 {mu}m is achieved leading to negligible deterioration of the muon momentum resolution. The second part of this work is dedicated to the study of the lepton flavour violating decay {tau}{yields}{mu}{mu}{mu}. Lepton flavour violation is predicted by almost every extension of the Standard Model. About 10{sup 12}{tau} leptons are produced per year at an instantaneous luminosity of 10{sup 33} cm{sup -2}s{sup -1} and a centre-of-mass energy of 14 TeV. Simulated data samples have been used to evaluate the sensitivity of the ATLAS experiment for {tau}{yields}{mu}{mu}{mu} decays with an integrated luminosity of 10 fb{sup -1}. Taking theoretical and experimental systematic uncertainties into account an upper limit on the signal branching ratio of B({tau}{yields}{mu}{mu}{mu}) <5.9 x 10{sup -7} at 90% confidence level is achievable. This result represents the first estimation in ATLAS. (orig.)

    Purpose: To present the dose per pulse dependence of various QA devices under Flattening Filter Free (FFF) conditions. Methods: Air and liquid filled ion chamber arrays, diode arrays, radiochromic film and optically stimulated luminescence detectors were investigated. All detectors were irradiated under similar conditions of varying dose per pulse on a TrueBeam linac. Dose per pulse was controlled by varying SSD from 70 to 160 cm providing a range from ~0.5 to ~3 mGy per pulse. MU rates of up to 2400 MU/min for 10X FFF and 1400 MU/min for the 6X FFF beam were used. Beam pulses were counted using the Profiler™ diode array and pulse timing was confirmed by examining linac node files. Delivered doses were calculated with the Eclipse™ treatment planning system. Results: The detectors show a range of behaviors depending on the detector type, as expected. Diode arrays show up to 4% change in sensitivity (sensitivity increases with increasing dose per pulse) over the range tested. Air and liquid ion chambers arrays show a change in sensitivity of up to 3% (air) and 6% (liquid) (sensitivity decreases with increasing dose per pulse) while film and OSLD do not demonstrate a dependence on dose per pulse. Conclusion: Dependence of detector response on dose per pulse varies considerably depending on detector design. Interplay between dose per pulse and MU rate also exists for some detectors. Due diligence is required to characterize detector response prior to implementation of a QA protocol for FFF treatment delivery. During VMAT delivery, the MU rate may also vary dramatically within a treatment fraction. We intend to further investigate the implications of this for VMAT FFF patient specific quality assurance. T Karan and F Viel have received partial funding through the Varian Research program.

  19. A broadly tunable autocorrelator for ultra-short, ultra-high power infrared optical pulses

    We describe the design of a crossed-beam, optical autocorrelator that uses an uncoated, birefringent beamsplitter to split a linearly polarized incident pulse into two orthogonally polarized pulses, and a Type II, SHG crystal to generate the intensity autocorrelation function. The uncoated beamsplitter accommodates extremely broad tunability while precluding any temporal distortion of ultrashort optical pulses at the dielectric interface, and the specific design provides efficient operation between 1 {mu}m and 4 {mu}m. Furthermore, the use of Type II SHG completely eliminates any single-beam doubling, so the autocorrelator can be operated at very shallow crossed-beam angles without generating a background pedestal. The autocorrelator has been constructed and installed in the Mark III laboratory at Duke University as a broadband diagnostic for ongoing compression experiments on the chirped-pulse FEL.

    Neutron diffraction·total scattering at pulsed neutron source is a powerful method to analyze the complex structure of disordered materials: liquids, glasses, amorphous materials and disordered crystals. The basic idea of the structure of disordered materials, the fundamental diffraction theory for disordered materials, and structure analysis of disordered materials using pulsed neutron diffraction·total scattering technique (TOF method) are described in detail. In addition, the precise information of the world highest class J-PARC MLF spallation neutron source and typical J-PARC neutron total scattering instrument NOVA are also given. Recent structural modelling methods of disordered materials such like reverse Monte Carlo (RMC) simulation method is briefly described using an example of the analysis of a typical disordered material silica glass.

    An efficient high power long wave infrared laser based on ZnGeP{sub 2} optical parametric oscillator pumped by a 2.09 {mu}m Tm:YLF/Ho:YAG laser at 10KHz pulse repetition rate is reported. The pump to idler conversion efficiency is 8% at 15.6 W Ho pump power level and a quantum efficiency of 31 % when the 1'idler wavelength is tuned at 8.08 {mu}m. The wavelength tuning range from 8-9.1 {mu}m is also achieved by rotating the ZGP crystal. (fundamental areas of phenomenology(including applications))

    The angular distribution and differential branching fraction of the decay $B^+ \\to K^+ \\mu^+\\mu^-$ are studied with a dataset corresponding to 1.0 fb$^{-1}$ of integrated luminosity, collected by the LHCb experiment. The angular distribution is measured in bins of dimuon invariant mass squared and found to be consistent with Standard Model expectations. Integrating the differential branching fraction over the full dimuon invariant mass range yields a total branching fraction of $B(B^+ \\to K^+ \\mu^+\\mu^-) = (4.36 ± 0.15 ± 0.18) \\times 10^{−7}$. These measurements are the most precise to date of the $B^+ \\to K^+ \\mu^+\\mu^-$ decay.

    We present the design and characterization of a high-contrast, petawatt-class Ti:sapphire chirped-pulse amplification (CPA) laser system. Two saturable absorbers and low-gain optical parametric chirped-pulse amplification (OPCPA) preamplifier in the double CPA laser chain have improved the temporal contrast to 1.4 × 1012 on the subnanosecond time scale at 70 terawatt level. Final uncompressed broadband pulse energy is 28 J, indicating the potential for reaching peak power near 600 terawatt. We also discuss the going upgrade to over petawatt level at a 0.1 Hz repetition rate briefly.

    The sharp variation of neutron attenuation at certain energies specific to particular nuclides (the lower range being from ∼1 eV up to ∼1 keV), can be exploited for the remote mapping of element and/or isotope distributions, as well as temperature probing, within relatively thick samples. Intense pulsed neutron beam-lines at spallation sources combined with a high spatial, high-timing resolution neutron counting detector, provide a unique opportunity to measure neutron transmission spectra through the time-of-flight technique. We present the results of experiments where spatially resolved neutron resonances were measured, at energies up to 50 keV. These experiments were performed with the intense flux low background NOBORU neutron beamline at the J-PARC neutron source and the high timing resolution (∼20 ns at epithermal neutron energies) and spatial resolution (∼55 µm) neutron counting detector using microchannel plates coupled to a Timepix electronic readout. Simultaneous element-specific imaging was carried out for several materials, at a spatial resolution of ∼150 µm. The high timing resolution of our detector combined with the low background beamline, also enabled characterization of the neutron pulse itself – specifically its pulse width, which varies with neutron energy. The results of our measurements are in good agreement with the predicted results for the double pulse structure of the J-PARC facility, which provides two 100 ns-wide proton pulses separated by 600 ns, broadened by the neutron energy moderation process. Thermal neutron radiography can be conducted simultaneously with resonance transmission spectroscopy, and can reveal the internal structure of the samples. The transmission spectra measured in our experiments demonstrate the feasibility of mapping elemental distributions using this non-destructive technique, for those elements (and in certain cases, specific isotopes), which have resonance energies below a few keV, and with lower

    Muon dynamics and forced chemical confinement fusion in three-layer arrangement consisting of the H/T, D{sub 2} (the degrader and moderator) and D/T fusion layers are investigated with a new kinetic model. Point kinematic equations are numerically solved to calculate the numbers of dt{mu}, tt{mu} and dd{mu} chain reactions. We show that the {mu}-cycling coefficient X{sub c} approximately equals 156, at optimal condition. Our model and results are in contradiction with beliefs of Mahdavi and Zanganeh. Our model is confirmed by recent experiment where was performed for the hydrogen mixture. (author)

  8. CP non-invariance and the K/sub s/ to mu /sup +/ mu /sup -/ decay rate

    Christ and Lee suggested CP non-invariance as an explanation of the low experimental K/sub L/ to mu /sup +/ mu /sup -/ decay rate. The authors discuss Hamiltonian realizations of this mechanism, and the lower bounds on the K/sub S/ to mu /sup +/ mu /sup -/ decay rate implied by them. The lower bound on the K/sub S/ to mu /sup +/ mu /sup -/ branching ratio varies in these models from 10 * 10/sup -7/ (for the most economical model) to 2 * 10/sup -7/. (20 refs).

  9. Measurement of the polarisation amplitudes in $B^0 \\rightarrow J/\\psi K^{*}(892)^0$ decays with the LHCb experiment

    Bien, Alexander; Schultz-Coulon, Hans-Christian

    In this thesis a measurement of the polarisation amplitudes and the corresponding strong phases of the decay $B^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) K^{*}(892)^0(K^+\\pi^-)$ is presented. Studying $B^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) K^{*}(892)^0(K^+\\pi^-)$ and $\\overline{B}^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) \\overline{K}^{*}(892)^0(K^-\\pi^+)$ decays separately allows for the measurement of direct CP violation. The Standard Model of particle physics does not predict any CP-violating processes for this decay channel. Thus, this analysis also serves as a search for new phenomena beyond the Standard Model. The measurement is performed using the full data sample collected with the LHCb detector in 2011 taken in proton-proton collisions at a centre-of-mass energy of $7$ TeV corresponding to an integrated luminosity of approximately $1.0$ fb$^{-1}$. The determination of the polarisation amplitudes requires an angular analysis of the final state particles to disentangle the three possible angular momentum states. The observ...

  10. Identification and Molecular Characterisation of a Novel Mu-Like Bacteriophage, SfMu, of Shigella flexneri.

    Directory of Open Access Journals (Sweden)

    Richa Jakhetia

    Full Text Available S. flexneri is the leading cause of bacillary dysentery in the developing countries. Several temperate phages originating from this host have been characterised. However, all S. flexneri phages known to date are lambdoid phages, which have the ability to confer the O-antigen modification of their host. In this study, we report the isolation and characterisation of a novel Mu-like phage from a serotype 4a strain of S. flexneri. The genome of phage SfMu is composed of 37,146 bp and is predicted to contain 55 open reading frames (orfs. Comparative genome analysis of phage SfMu with Mu and other Mu-like phages revealed that SfMu is closely related to phage Mu, sharing >90% identity with majority of its proteins. Moreover, investigation of phage SfMu receptor on the surface of the host cell revealed that the O-antigen of the host serves as the receptor for the adsorption of phage SfMu. This study also demonstrates pervasiveness of SfMu phage in S. flexneri, by identifying complete SfMu prophage strains of serotype X and Y, and remnants of SfMu in strains belonging to 4 other serotypes, thereby indicating that transposable phages in S. flexneri are not uncommon. The findings of this study contribute an advance in our current knowledge of S. flexneri phages and will also play a key role in understanding the evolution of S. flexneri.

    We search for the purely leptonic decay B{sup {+-}} {yields} {mu}{sup {+-}}{nu}{sub {mu}} in the full BABAR dataset, having an integrated luminosity of approximately 426 fb{sup -1}. We adopt a fully inclusive approach, where the signal candidate is identified by the highest momentum lepton in the event and the companion B is inclusively reconstructed without trying to identify its decay products. We set a preliminary upper limit on the branching fraction of {Beta}(B{sup {+-}} {yields} {mu}{sup {+-}}{nu}{sub {mu}}) < 1.3 x 10{sup -6} at the 90% confidence level, using a Bayesian approach.

    A non-optical, pulsed reset technique for use in charge sensitive preamplifiers with Si(Li) X-ray semiconductor detectors of conventional polarity is described. The phenomenon of impact ionization in the field effect transistor is used for charge restoration. The process is controlled via the detector capacitance. The method needs no extra components in the input circuitry. No significant resolution degradation can be detected up to 600 kcps Mn K intensity if following the 5 {mu}s resetting pulse the signal processor is inhibited for 50 {mu}s. (orig.).

    A search for the decay $B_{s}^0 \\rightarrow \\overline{K}{}^{*0}\\mu^+\\mu^-$ is presented using data sets corresponding to 1.0, 2.0 and 1.6 $\\text{fb}^{-1}$ of integrated luminosity collected during $pp$ collisions with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, respectively. An excess is found over the background-only hypothesis with a significance of 3.4 standard deviations. The branching fraction of the $B_{s}^0 \\rightarrow \\overline{K}{}^{*0}\\mu^+\\mu^-$ decay is determined to be $\\mathcal{B}(B_{s}^0 \\rightarrow \\overline{K}{}^{*0}\\mu^+\\mu^-) = [2.9 \\pm 1.0~(\\text{stat}) \\pm 0.2~(\\text{syst}) \\pm 0.3~(\\text{norm})] \\times 10^{-8}$, where the first and second uncertainties are statistical and systematic, respectively. The third uncertainty is due to limited knowledge of external parameters used to normalise the branching fraction measurement.

  14. Laser breakdown with millijoule trains of picosecond pulses transmitted through a hollow-core photonic-crystal fibre

    Sequences of picosecond pulses with a total energy in the pulse train of about 1 mJ are transmitted through a hollow-core photonic-crystal fibre with a core diameter of approximately 14 mu m. The fluence of laser radiation coupled into the core of the fibre under these conditions exceeds the breakdown threshold of fused silica by nearly an order of magnitude. The laser beam coming out of the fibre is then focused to produce a breakdown on a solid surface. Parameters of laser radiation were chosen in such a way as to avoid effects related to the excitation of higher order waveguide modes and ionization of the gas filling the fibre in order to provide the possibility to focus the output beam into a spot with a minimum diameter, thus ensuring the maximum spatial resolution and the maximum power density in the focal spot.

    A search for pair production of doubly charged Higgs bosons in the process p (p) over bar -->H++H---->mu(+)mu(+)mu(-)mu(-) is performed with the D0 run II detector at the Fermilab Tevatron. The analysis is based on a sample of inclusive dimuon data collected at an energy of roots=1.96 TeV, corresponding to an integrated luminosity of 113 pb(-1). In the absence of a signal, 95% confidence level mass limits of M(H-L(+/-+/-))>118.4 GeV/c(2) and M(H-R(+/-+/-))>98.2 GeV/c(2) are set for left-hande...

  16. First results from the MuLan and MuCap experiments

    MuLan and MuCap are ongoing experiments at the Paul Scherrer Institut, Switzerland, that use the muon lifetime to determine fundamental weak interaction parameters. The goal of MuLan is a 1 ppm measurement of the positive muon lifetime τ μ + to determine the Fermi constant G F to 0.5 ppm. The goal of MuCap is to make a 1% determination of the rate Λ S of the process of nuclear muon capture by the proton, μp→nν, by measuring the μ - disappearance rate in hydrogen gas to 10 ppm and subtracting the world average for the μ + decay rate. A 1% determination of the capture rate Λ S is of interest because it would enable a 7% determination of g P , the induced pseudoscalar coupling of the nucleon. In 2007, both experiments published first results based upon data collected by each in 2004. MuLan reported an 11 ppm μ + lifetime measurement, τ μ + = 2.197 013(24) μs, resulting in a new, 9.6 ppm world average, τ μ + = 2.197 019(21) μs, which determines the Fermi constant, G F = 1.166 371(6)x10 -5 GeV -2 , to 5 ppm. MuCap reported a 3% measurement of the muon capture rate from the hyperfine singlet ground state of the μp atom, Λ S = 725.0±17.4 s -1 , from which a 15% value for the pseudoscalar coupling, g P (q 2 = -0.88m μ 2 ) = 7.3±1.1, was extracted

  18. Towards the first $B(B^{0}_{(s)} \\to \\mu^+\\mu^−)$ measurements with the LHCb detector

    The rare decays $B^{0}_{s} \\to \\mu^+ \\mu^-$ and $B^{0} \\to \\mu^+ \\mu^-$ are benchmark channels to constrain models beyond the Standard Model (BSM) with a larger Higgs sector. In the SM, the branching fraction of these decays is predicted with a good accuracy: $\\mathcal{B}(B^{0}_{(s)} \\to \\mu^+ \\mu^-) = (3.2 \\pm 0.2) \\times 10^{-9}$ and $\\mathcal{B}(B^{0} \\to \\mu^+ \\mu^-) = (0.10 \\pm 0.01) \\times 10^{-10}$. Any deviation from these values can lead to indications of physics BSM. The core of this thesis comprises two main topics: the background rejection and the signal yields extraction. We have optimized a multivariate classifier based on the boosted decision trees technique allowing for a drastic reduction of the $B \\to h^+ h'^-$ ($h \\equiv \\pi, K$) background. After the selection process, about 76$\\%$ of the combinatorial background for $B^{0}_{s} \\to \\mu^+ \\mu^-$ is removed, while keeping a signal efficiency of about 92$\\%$. A further discrimination between signal and background is accomplished with anoth...

    A search for heavy Majorana neutrinos produced in the $B^- \\to \\pi^+\\mu^-\\mu^-$ decay mode is performed using 3 fb$^{-1}$ of integrated luminosity collected with the LHCb detector in $pp$ collisions at center-of-mass energies of 7 TeV and 8 TeV at the LHC. Neutrinos with masses in the range 250-5000 MeV and lifetimes from zero to 1000 ps are probed. In the absence of a signal, upper limits are set on the branching fraction ${\\cal{B}}(B^- \\to \\pi^+\\mu^-\\mu^-)$ as functions of neutrino mass and lifetime. These limits are on the order of $10^{-9}$ for short neutrino lifetimes of 1 ps or less. Limits are also set on the coupling between the muon and a possible fourth-generation neutrino.

  20. Antibound states for a class of one-dimensional Schroedinger Operators

    Let delta(x) be the Dirac's delta, q(x) element of L/sup 1/(R) L/sup 2/(R) be a real valued function, and lambda, ..mu.. element of R; we will consider the following class of one-dimensional formal Schroedinger operators on L/sup 2/(R) H(lambda,..mu..) = - (d/sup 2//dx/sup 2/) + lambdadelta(x) + ..mu..q(x). It is known that to the formal operator H(lambda, ..mu..) may be associated a selfadjoint operator H(lambda, ..mu..) on L/sup 2/(R). If q is of finite range, for lambda < 0 and /..mu../ is small enough, we prove that H(lambda,..mu..) has an antibound state; that is the resolvent of H(lambda,..mu..) has a pole on the negative real axis on the second Riemann sheet.

    A search for the decay $K_{\\rm\\scriptscriptstyle S}^0\\rightarrow\\mu^{+}\\mu^{-}$ is performed, based on a data sample of 1.0\\,fb$^{-1}$ of $pp$ collisions at $\\sqrt{s}$ = 7\\,TeV collected by the LHCb experiment at the Large Hadron Collider. The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of $\\mathcal{B}(K_{\\rm\\scriptscriptstyle S}^0\\rightarrow\\mu^{+}\\mu^{-}) < 11 (9)\\times10^{-9}$ at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement.

    We perform a study of the standard model fit to the mixing quantities {Delta}M{sub B{sub s}}, and {Delta}{Lambda}{sub B{sub s}}/{Delta}M{sub B{sub s}} in order to bound contributions of new physics (NP) to B{sub s} mixing. We then use this to explore the branching fraction of B{sub s} {yields} {mu}{sup +}{mu}{sup -} in certain models of NP. In most cases, this constrains NP amplitudes for B{sub s} {yields} {mu}{sup +}{mu}{sup -} to lie below the standard model component.

    We demonstrate optical parametric chirped-pulse amplification (OPCPA) based on two-beam pumping, using sub-nanosecond pulses generated by stimulated Brillouin scattering compression. Seed pulse energy, duration, and center wavelength were 5 nJ, 220 ps, and ˜1065 nm, respectively. The 532 nm pulse from a Q-switched Nd:YAG laser was compressed to ˜400 ps in heavy fluorocarbon FC-40 liquid. Stacking of two time-delayed pump pulses reduced the amplifier gain fluctuation. Using a walk-off-compensated two-stage OPCPA at a pump energy of 34 mJ, a total gain of 1.6 × 105 was obtained, yielding an output energy of 0.8 mJ. The amplified chirped pulse was compressed to 97 fs.

    To improve the purity of intense pulsed ion beams, a new type of pulsed ion beam accelerator named 'bipolar pulse accelerator' was proposed. To confirm the principle of the accelerator a prototype of the experimental system was developed. The system utilizes By type magnetically insulated acceleration gap and operated with single polar negative pulse. A coaxial gas puff plasma gun was used as an ion source, which was placed inside the grounded anode. Source plasma (nitrogen) of current density {approx}25A/cm2, duration {approx}1.5{mu}s was injected into the acceleration gap by the plasma gun. The ions were successfully accelerated from the grounded anode to the drift tube by applying negative pulse of voltage 240kV, duration 100ns to the drift tube. Pulsed ion beam of current density {approx}40A/cm2, duration {approx}50ns was obtained at 41mm downstream from the anode surface. To evaluate the irradiation effect of the ion beam to solid material, an amorphous silicon thin film of thickness {approx}500nm was used as the target, which was deposited on the glass substrate. The film was found to be poly-crystallized after 4-shots of the pulsed nitrogen ion beam irradiation.

    A search for the rare decay $\\Sigma^+ \\to p \\mu^+ \\mu^-$ is performed using $pp$ collision data recorded by the LHCb experiment at centre-of-mass energies $\\sqrt{s} = 7$ and $8$ TeV, corresponding to an integrated luminosity of $3 fb^{-1}$. An excess of events is observed with respect to the background expectation, with a signal significance of 4.1 standard deviations. No significant structure is observed in the dimuon invariant mass distribution, in contrast with a previous result from the HyperCP experiment. The measured $\\Sigma^+ \\to p \\mu^+ \\mu^-$ branching fraction is $(2.2\\,^{+\\,1.8}_{-\\,1.3})\\times 10^{-8}$, where statistical and systematic uncertainties are included, which is consistent with the Standard Model prediction.

    Mu3e is a novel experiment searching for charged lepton flavor violation in the rare decay $\\mu^+ \\rightarrow e^+e^-e^+$. Decay vertex position, decay time and particle momenta have to be precisely measured in order to reject both accidental and physics background. A silicon pixel tracker based on $50\\,\\mu$m thin high voltage monolithic active pixel sensors (HV-MAPS) in a 1 T solenoidal magnetic field provides precise vertex and momentum information. The MuPix chip combines pixel sensor cells with integrated analog electronics and a periphery with a complete digital readout. The MuPix7 is the first HV-MAPS prototype implementing all functionalities of the final sensor including a readout state machine and high speed serialization with 1.25 Gbit/s data output, allowing for a streaming readout in parallel to the data taking. The observed efficiency of the MuPix7 chip including the full readout system is $\\geq99\\%$ in a high rate test beam.

    Many biomedical classification problems are multi-label by nature, e.g., a gene involved in a variety of functions and a patient with multiple diseases. The majority of existing classification algorithms assumes each sample with only one class label, and the multi-label classification problem remains to be a challenge for biomedical researchers. This study proposes a novel multi-label learning algorithm, hMuLab, by integrating both feature-based and neighbor-based similarity scores. The multiple linear regression modeling techniques make hMuLab capable of producing multiple label assignments for a query sample. The comparison results over six commonly-used multi-label performance measurements suggest that hMuLab performs accurately and stably for the biomedical datasets, and may serve as a complement to the existing literature.

    The growth of highly functionalised poly allyl alcohol films by pulsed plasma polymerisation of CH{sub 2} =CHCH{sub 2}OH on biomedical grade polyurethane has been followed by X-ray photoelectron spectroscopy (XPS) and contact angle measurements. Film thickness is observed to increase approximately linearly with plasma modification time, suggesting a layer-by-layer growth mode of poly allyl alcohol. Water contact angle measurements reveal the change in the surface free energy of wetting decreases linearly with plasma modification up to the monolayer point after which a constant limiting value of -24 mJ m{sup -2} was attained. Films prepared at 20 W plasma power with a duty cycle of 10 {mu}s:500 {mu}s exhibit a high degree of hydroxyl (-OH) retention with minimal fragmentation of the monomer observed. Increasing the plasma power up to 125 W is found to improve -OH retention at the expense of ether formation generating films close to the monomer stoichiometry. Duty cycle plays an important role in controlling both film composition and thickness, with longer off times increasing -OH retention, while longer on times enhance allyl alcohol film growth.

  11. The Mu2e crystal calorimeter and improvements in the $\\mu^-\\mbox{N} \\to e^-\\mbox{N}$ search sensitivity

    The Mu2e experiment will search for Charged Lepton Flavor Violation (CLFV) looking at the conversion of a muon into an electron in the field of an aluminum nucleus. About $7\\cdot 10^{17}$ muons, provided by a dedicated muon beam line in construction at the Fermi National Accelarator Laboratory (Fermilab), will be stopped in 3 years in the Aluminum target. The corresponding single event sensitivity will be $2.5\\cdot 10^{-17}$. The Standard Model of particle physics, even extendend to include the finite neutrino masses, predicts the ratio Rμe between muon conversions and muon nuclear captures to be $\\sim 10^{- 52}$. Several extensions of the Standard Model predict Rμe to be in the range of $10^{-14} - 10^{-18}$. % The current best experimental limit, set by the SINDRUM II experiment is $7 \\cdot 10^{-13}$ @ $90\\%$ CL. The Mu2e experiment plans to improve this experimental limit by four order of magnitude to test many of the possible extensions of the Standard Model. To reach this ambitious goal, the Mu2e experiment is expected to use an intense pulsed muon beam, and rely on a detector system composed of a straw tube tracker and a calorimeter made of pure CsI crystals. The calorimeter plays a central role in the Mu2e measurement, providing particle identification capabilities that are necessary for rejecting two of the most dangerous background sources that can mimic the μ⁻N → e⁻N conversion electron: cosmic muons and $\\bar{p}$ induced background. The calorimeter information allows also to improve the tracking performance. Thanks to a calorimeter-seeded track finder algorithm, it is possible to increase the track reconstruction efficiency, and make it more robust with respect to the occupancy level. Expected performances of the calorimeter have been studied in a beam test at the Beam Test Facility in Frascati (Rome, Italy). A reduced scale calorimeter prototype has been exposed to an electron beam, with energy varying from 80 to 140

  12. Study and realisation of a miniature optical parametric oscillator; Etude et realisation d`un oscillateur parametrique optique miniature

    We used micro-chip lasers developed in LETI to pump a miniature Optical Parametric Oscillator (OPO). The micro-chip lasers can be fabricated at very low cost, using collective fabrication processes. The micro-chip lasers we used are Nd:YAG lasers, passively Q-switched by a Cr{sup 4+}:YAG saturable absorber. They are pumped with 1 W standard laser diodes and emit pulses which characteristics are a few {mu}J energies and several kHz repetition rates. The main problem in pumping an OPO with such a micro-chip laser is to reach its oscillation threshold. We are calculated this threshold and showed that it will be impossible to pump an extra-cavity OPO with a micro-chip laser. We first worked with an extra-cavity OPO based on the non-critical-phase-matching conversion 1.064 {mu}m{yields}1.572 {mu}m + 3.293 {mu}m in a KTP crystal, pumped with a mJ energy laser. In spite of good results (low thresholds of 200 {mu}J) and as we have calculated, it was not be possible to pump such an OPO with our micro-chip lasers (10{mu}J maximum energies). We developed an intracavity micro-chip OPO (with the OPO inside the laser cavity). In this configuration, the OPO benefits from the intracavity laser intensity to reach the oscillation threshold. The micro-chip OPO emits about 10 ns pulses at 1.572 {mu}m with a few {mu}J energy at several kHz repetition rate. To our knowledge, we realised the first micro-chip-OPO using a 1 W standard diode pumped, passively Q-switched micro-chip laser. In order to improve the performances of the intracavity micro-chip-OPO, we developed a software for numerical modelling its operation. (author) 80 refs.

    Full Text Available Abstract Cicadas are usually studied regarding their importance in agriculture. However, the possibility of this group to represent a pulse of nutrients can also imply on the success of a given species in the biome. The aim of this study was to assess the level of total soluble proteins and lipids of Fidicina mannifera (Fabricius, 1803, and to determine whether the species can promote a pulse of nutrients in two vegetation classes of the Brazilian Cerrado. To assess the pulse of nutrients, it was concluded the determination of total soluble proteins and lipids from samples of males and adult females of F. mannifera, and the spatial distribution of exuviae of this species was also calculated in two vegetation classes of the Brazilian Cerrado. The amount of protein provided by each individual did not differ between males and females (p = 0.66 but females had 40% more lipids than males (p = 0.05. Regarding F. mannifera the gallery forest offered 11.75 g/ha of protein, 3.91 g/ha of lipids, and the Cerrado stricto sensu offered 4.25 g/ha of protein, and 1.41 g/ha of lipid. The male cicadas have a hollow abdomen, which houses a resonance chamber for sound production in order to attract females to mate, and females store larger amounts of lipids, mainly located in the abdominal cavity, where the body fat is directly linked to the reproductive system for the development of the ovaries and egg production after emergence. The mass occurrence of F. mannifera in the Brazilian Cerrado and the fast availability of proteins and lipids make this species a food resource that can directly impact the diet of secondary consumers and scavengers, although the amount of nutrients available by F. mannifera does not promote a pulse of nutrients in the study site.

    Long life pulse power supply for Cu vapor laser was developed. This is composed of the pulse generation circuit and the pulse compression circuit. Current pulse of 10 mu second pulse width is generated in the pulse generating circuit by switching electric charge on the condensor charged through GTO (gate turn off) thyristors. The pulse compression circuit makes the current pulse fast to 300ms utilizing the difference of inductance at the saturation and the unsaturation on the circuit which uses a reactor having saturable property using a ferromagnetic substance for the core as the magnetic switch. The operation was carried out at the GTO generasting full power. Co base amorphous alloy of low loss was used for the core of saturable inductor and the circuit efficiency of 77% could be obtained by suppressing the heat generation in core even at 4,000Hz operation. The full output power of 8.2kW was possible which corresponds to 100W class laser oscillation. Repeated Cu vapor laser oscillation of 30W succeeded at the condition of 4,000Hz and power supply output of 5.9kW. 7 refs., 21 figs., 8 tabs.

    The angular distributions of the rare decays $B^+ \\to K^+\\mu^+\\mu^-$ and $B^0 \\to K^0_{\\rm\\scriptscriptstyle S}\\mu^+\\mu^-$ are studied with data corresponding to 3$~$fb$^{-1}$ of integrated luminosity, collected in proton-proton collisions at 7 and 8$~$TeV centre-of-mass energies with the LHCb detector. The angular distribution is described by two parameters, $F_{\\rm H}$ and the forward-backward asymmetry of the dimuon system $A_{\\rm FB}$, which are determined in bins of the dimuon mass squared. The parameter $F_{\\rm H}$ is a measure of the contribution from (pseudo)scalar and tensor amplitudes to the decay width. The measurements of $A_{\\rm FB}$ and $F_{\\rm H}$ reported here are the most precise to date and are compatible with predictions from the Standard Model.

    We propose and demonstrate an efficient sum-frequency mixing scheme based on narrowband and chirped broadband pulses. It combines the advantages of wider spectral acceptance bandwidth and of alleviating the temporal walk-off, which are both beneficial to higher conversion efficiency. Chirped sum-frequency pulses at 455 nm with energy up to 360 µJ, corresponding to a conversion efficiency of ∼ 40%, are obtained and the pulses can be compressed to ∼ 110 fs. The sum-frequency mixing scheme may provide a promising route to the efficient generation of deep-ultraviolet femtosecond pulses

    Highlights: Black-Right-Pointing-Pointer Bioactive glass-ceramic coatings for bone tissue repair and regeneration. Black-Right-Pointing-Pointer Pulsed Lased Deposition allowed congruent transfer of target composition to coating. Black-Right-Pointing-Pointer Target was prepared by sol-gel process suitable for compositional tailoring. Black-Right-Pointing-Pointer Titanium, widely used for orthopaedics and dental implants, was used as substrate. Black-Right-Pointing-Pointer The physico-chemical properties of the prepared coatings are reported. -- Abstract: The deposition of innovative glass-ceramic composition (i.e. RKKP) coatings by Pulsed Lased Deposition (PLD) technique is reported. RKKP was synthesised following two methodologies: melt-processing and sol-gel, the latter being particularly suitable to tailor the compositional range. The PLD advantage with respect to other deposition techniques is the congruent transfer of the target composition to the coating. The physico-chemical properties of films were investigated by Scanning Electron and Atomic Force Microscopies, Fourier Transform Infrared Spectroscopy, Angular and Energy Dispersive X-ray Diffraction, and Vickers microhardness. The deposition performed at 12 J/cm{sup 2} and 500 Degree-Sign C allows to prepare crystalline films with the composition that replicates rather well that of the initial targets. The 0.6 {mu}m thin melt-processing RKKP films, possessing the hardness of 25 GPa, and the 4.3 {mu}m thick sol-gel films with the hardness of 17 GPa were obtained.

    A review of the search for the very rare decays $B^{0}_{s} \\rightarrow \\mu^+ \\mu^-$ and $B^{0} \\rightarrow \\mu^+ \\mu^-$ with the LHCb experiment is presented. These decays are suppressed within the Standard Model as they can only occur via helicity suppressed loop diagrams. However, their amplitudes can be significantly different in many New Physics scenarios, especially in those with an extended Higgs sector. Therefore, these decays are a sensitive probe of physics beyond the Standard Model. The study is performed using $\\sim 37$ $pb^{-1}$ of pp collisions at $\\sqrt{s}$ = 7 TeV collected by the experiment at the Large Hadron Collider at CERN. For these dimuon decays the LHCb has reached sensitivities similar to the best existing limits. The resulting upper limits are $\\mathcal{B}(B^{0}_{s} \\rightarrow \\mu^+ \\mu^-)<$ 56 $\\times$ $10^{-9}$ and $\\mathcal{B}(B^{0} \\rightarrow \\mu^+ \\mu^-)<$ 15 $\\times$ $10^{-9}$ at $95\\%$ confidence level. With the number of pp colisions expected in 2011 the LHCb will ...

    We report the detection of pulsed gamma-rays from the young, spin-powered radio pulsar PSR J2021+3651 using data acquired with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). The light curve consists of two narrow peaks of similar amplitude separated by 0.468 {+-} 0.002 in phase. The first peak lags the maximum of the 2 GHz radio pulse by 0.162 {+-} 0.004 {+-} 0.01 in phase. The integral gamma-ray photon flux above 100 MeV is (56 {+-} 3 {+-} 11) x 10{sup -8} cm{sup -2} s{sup -1}. The photon spectrum is well-described by an exponentially cut-off power law of the form dF/dE = kE{sup -{Gamma}}e{sup (-E/E{sub c})} where the energy E is expressed in GeV. The photon index is {Gamma} = 1.5 {+-} 0.1 {+-} 0.1 and the exponential cut-off is E{sub c} = 2.4 {+-} 0.3 {+-} 0.5 GeV. The first uncertainty is statistical and the second is systematic. The integral photon flux of the bridge is approximately 10% of the pulsed emission, and the upper limit on off-pulse gamma-ray emission from a putative pulsar wind nebula is < 10% of the pulsed emission at the 95% confidence level. Radio polarization measurements yield a rotation measure of RM = 524 {+-} 4 rad m{sup -2} but a poorly constrained magnetic geometry. Re-analysis of Chandra data enhanced the significance of the weak X-ray pulsations, and the first peak is roughly phase-aligned with the first gamma-ray peak. We discuss the emission region and beaming geometry based on the shape and spectrum of the gamma-ray light curve combined with radio and X-ray measurements, and the implications for the pulsar distance. Gamma-ray emission from the polar cap region seems unlikely for this pulsar.

    A large number of single mode fibers (SMF) for 1.3 {mu}m light are installed in electric power communication facilities. On the other hand, light of 1.5 {mu}m band is being used more in the capacity increasing technology to minimize transmission loss. If this is applied to the current SMF, waveform distortion is generated due to wavelength dispersion, thus the transmission speed and distance are limited. In order to evaluate quantitatively the effects of a wavelength dispersion compensating technology, a method was developed to derive time change in each wavelength component in light pulse. No sufficient wavelength separation is possible if permeation bandwidth of a wavelength filter is wider than the wavelength width of the light pulse. Therefore, a method was developed to derive time change in the wavelength components in the light pulse from small difference in the measured light waveforms after transmission when the central wavelength of a wavelength variable filter is varied. It was possible from comparing the method to derive the wavelength dispersion amount and the dispersion compensation amount. Since the method reveals simultaneously the distribution of strength against wavelength and time contained in light pulse, the method is advantageous in elucidating compensation limit and causes for compensation errors. The effectiveness of the method was verified by a 1.5-{mu}m light transmission test. 14 refs., 26 figs., 2 tabs.

    We present and discuss a set of boundary conditions (BCs) to use in three-dimensional, mesoscopic, finite element models of mid-infrared pulsed laser ablation of brittle materials. These models allow the study of the transient displacement and stress fields generated at micrometer scales during and after one laser pulse, where using conventional BCs may lead to some results without physical significance that can be considered an artefact of the calculations. The proposed BCs are tested and applied to a micrometer-scale continuous model of human dental enamel under CO{sub 2} radiation (10.6 {mu}m, 0.35 {mu}s pulse, sub-ablative fluence), giving rise to the following results: the highest stress is obtained at the irradiated surface of the model, at the end of the laser pulse, but afterwards it decreases rapidly until it becomes significantly lower than the stress in a region 2.5 {mu}m deep in the model; a thermally induced vibration in the material is predicted. This non-intuitive dynamics in stress and displacement distribution cannot be neglected and has to be considered in dynamic laser ablation models, since it may have serious implications in the mechanisms of ablation.

    The angular analysis of the rare baryon decay of $\\Lambda_{b}\\rightarrow \\Lambda (\\rightarrow p\\pi^{-})\\mu^{+}\\mu^{-}$ in high $q^{2}$ is presented. The dataset that is used corresponds to an integrated luminosity of 5.0 fb$^{-1}$ of pp - collision data collected at centre-of-mass energies between 7 and 13 TeV by the LHCb detector in 2011, 2012, 2015 and 2016. Angular observables are determined using a moment analysis of the angular distribution.

    AUTHOR|(CDS)2091898; Neri, Nicola

    In this thesis the first search for $C\\!P$-violation on rare heavy beauty baryon $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decays is described. This analysis is carried out on the whole dataset recorded by the LHCb experiment during 2011 and 2012. The $C\\!P$ symmetry violation study is one of the most promising method for searching physics beyond the standard model, as the measured amount of $C\\!P$-violation in high-energy physics experiments, even though compatible with standard model expectations, is not sufficient for explaining the observed matter-antimatter asymmetry of our universe. The $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decays occur via electroweak loop diagrams which allow possible new physics fields to give this process a sensible contribution. For the $\\Lambda_b\\to pK^-\\mu^+\\mu^-$ decay a limited quantity of $C\\!P$-violation is expected in the standard model, making this transition suited to look for beyond standard model physics. In this thesis, $C\\!P$-violation is searched exploiting direct $C\\!P$ asymmetries and ...

    A broad peaking structure is observed in the dimuon spectrum of $B^+ \\to K^+ \\mu^+\\mu^-$ decays in the kinematic region where the kaon has a low recoil against the dimuon system. The structure is consistent with interference between the $B^+ \\to K^+ \\mu^+\\mu^-$ decay and a resonance and has a statistical significance exceeding six standard deviations. The mean and width of the resonance are measured to be $4191^{+9}_{-8}\\mathrm{\\,Me\\kern -0.1em V/}c^2$ and $65^{+22}_{-16}\\mathrm{\\,Me\\kern -0.1em V/}c^2$, respectively, where the uncertainties include statistical and systematic contributions. These measurements are compatible with the properties of the $\\psi(4160)$ meson. First observations of both the decay $B^+ \\to \\psi(4160) K^+$ and the subsequent decay $\\psi(4160) \\to \\mu^+\\mu^-$ are reported. The resonant decay and the interference contribution make up 20% of the yield for dimuon masses above 3770  MeV/c2. This contribution is larger than theoretical estimates.

  6. A pulse generator for xenon lamps

    Janata, E

    2002-01-01

    A pulse generator is described, which enhances the analyzing light emitted from a xenon lamp as used in kinetic photospectrometry experiments. The lamp current is increased to 600 A for a duration of 3 ms; the current is constant within +-0.2% during a time interval of 2 ms. Because of instabilities of the lamp arc during pulsing, the use of the enhanced light source is limited to measuring times up to 500 mu s. The enhancement in light intensity depends on the wavelength and amounts to more than 400-fold in the UV-region.

  7. Search for VHE γ-ray emission from the direction of the two millisecond pulsars PSR J0437-4715 and PSR J1824-2452 and the composite supernova remnant Kes 75 with H.E.S.S

    This work reports on the search for pulsed and steady very-high energy (VHE) gamma-ray emission in the energy range extending from 100 GeV up to 100 TeV from the direction of three pulsars with the High Energy Stereoscopic System (H.E.S.S.). Pulsed gamma-ray radiation from pulsars with energies beyond 100 GeV was found thus far only for the young and energetic Crab pulsar. A special class of pulsar wind nebulae (PWNe) is associated with composite supernova remnants (SNRs) where the PWN is centered in an expanding SNR shell. In the first part of this thesis, the results on the search for pulsed and steady VHE gamma-ray emission from the two millisecond pulsars, PSR J0437-4715 and PSR J1824-2452, are presented. Parts of the observations were conducted in a special trigger setup (the topological trigger with convergent pointing) to reduce the energy threshold of the instrument. No signal of pulsed or steady emission is found and upper limits on the pulsed and steady gamma-ray flux are derived. The upper limits on the pulsed gamma-ray flux are compared to existing model predictions and, in the case of PSR J1824-2452, allow the range of possible viewing geometries in some models to be constrained. In the second part of this work, results on the search for pulsed and steady VHE gamma-ray emission from the direction of the composite SNR Kes 75 are presented. The PWN in the center of Kes 75 is powered by a very young and powerful pulsar, PSR J1846-0258, that has an exceptionally high magnetic field. While no hint for pulsed emission is found, steady VHE gamma-ray emission is detected with a statistical significance of 10 sigma from a point-like source. The VHE gamma-ray emission is spatially coincident with the PWN and the SNR shell. Both are discussed as a possible origin for the observed emission. The pulsar of Kes 75 would be the youngest pulsar known to date to power a VHE PWN.

    2009-01-01

    We report the detection of pulsed gamma-rays from the young, spin-powered radio pulsar PSR J2021+3651 using data acquired with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). The light curve consists of two narrow peaks of similar amplitude separated by 0.468 ± 0.002 in phase. The first peak lags the maximum of the 2 GHz radio pulse by 0.162 ± 0.004 ± 0.01 in phase. The integral gamma-ray photon flux above 100 MeV is (56 ± 3 ± 11) x 10 -8 cm -2 s -1 . The photon spectrum is well-described by an exponentially cut-off power law of the form dF/dE = kE -# Gamma#e (-E/E c ) where the energy E is expressed in GeV. The photon index is Γ = 1.5 ± 0.1 ± 0.1 and the exponential cut-off is E c = 2.4 ± 0.3 ± 0.5 GeV. The first uncertainty is statistical and the second is systematic. The integral photon flux of the bridge is approximately 10% of the pulsed emission, and the upper limit on off-pulse gamma-ray emission from a putative pulsar wind nebula is -2 but a poorly constrained magnetic geometry. Re-analysis of Chandra data enhanced the significance of the weak X-ray pulsations, and the first peak is roughly phase-aligned with the first gamma-ray peak. We discuss the emission region and beaming geometry based on the shape and spectrum of the gamma-ray light curve combined with radio and X-ray measurements, and the implications for the pulsar distance. Gamma-ray emission from the polar cap region seems unlikely for this pulsar.

    The GAMBLE II water dielectric pulse power generator, in 1970, was the forerunner of the high energy (> 50 kJ) class of water dielectric generators. It has been redesigned internally to make maximum use of its original outer conductor shell and to optimize it for the positive polarity mode of operation for positive ion beam experimentation. The new design also initiates the use of an oil dielectric multi-channel switch at the output of the pulse forming line. This switch, because of its low capacitance, eliminates the need for an extra prepulse switch. The upgraded version has been tested up to power and energy levels which are nearly twice the original

    We numerically demonstrate all-optical logic operations with quantum dots (QDs) embedded in a bimodal photonic-crystal waveguide using Maxwell-Bloch equations in a slowly varying envelope approximation (SVEA). The two-level QD excitation level is controlled by one or more femtojoule optical driving pulses passing through the waveguide. Specific logic operations depend on the relative pulse strengths and their detunings from an inhomogeneouslly broadened (about 1% for QD transitions centered at 1.5 {mu}m) QD transition. This excitation controlled two-level medium then determines passage of subsequent probe optical pulses. Envelope equations for electromagnetic waves in the linear dispersion and cutoff waveguide modes are derived to simplify solution of the coupled Maxwell-Bloch equations in the waveguide. These determine the quantum mechanical evolution of the QD excitation and its polarization, driven by classical electromagnetic (EM) pulses near a sharp discontinuity in the EM density of states of the bimodal waveguide. Different configurations of the driving pulses lead to distinctive relations between driving pulse strength and probe pulse passage, representing all-optical logic and, or, and not operations. Simulation results demonstrate that such operations can be done on picosecond time scales and within a waveguide length of about 10 {mu}m in a photonic-band-gap (PBG) optical microchip.

    The GRENOUILLE traces of Gemini pulses (15 J, 30 fs, PW, shot per 20 s) were acquired in the Gemini Target Area PetaWatt at the Central Laser Facility (CLF), Rutherford Appleton Laboratory (RAL). A comparison between the characterizations of the laser pulse parameters made using two different types of algorithms: Video Frog and GRenouille/FrOG (GROG), was made. The temporal and spectral parameters came out to be in great agreement for the two kinds of algorithms. In this experimental campaign it has been showed how GROG, the developed algorithm, works as well as VideoFrog algorithm with the PetaWatt pulse class. - Highlights: • Integration of the diagnostic tool on high power laser. • Validation of the GROG algorithm in comparison to a well-known commercial available software. • Complete characterization of the GEMINI ultra-short high power laser pulse.

    We have been developing a new type of Nb 3 Sn superconductor with high elastic modulus fibers for the application of high field pulsed superconducting magnets. We call this type of conductor FRS(Fiber-Reinforced Superconductor). This paper tries to show that FRS has great potential for the construction of a 15T-class pulsed magnet, with the size of which equals to that of the central solenoid of ITER(International Thermonuclear Experimental Reactor), because each monofilamentary FRS can support the part of hoop stress under operation of the magnet. Conceptual design of a basic strand with monofilamentary FRS, construction of the first- and second- level subcable, cooling condition of CICC(Cable in conduit conductor), stability and ac losses of the conductor are discussed.

    We introduce a new method for analyzing the aperiodic variability of coherent pulsations in accreting millisecond X-ray pulsars (AMXPs). Our method involves applying a complex frequency correction to the time-domain light curve, allowing for the aperiodic modulation of the pulse amplitude to be robustly extracted in the frequency domain. We discuss the statistical properties of the resulting modulation spectrum and show how it can be correlated with the non-pulsed emission to determine if the periodic and aperiodic variability are coupled processes. Using this method, we study the 598.88 Hz coherent pulsations of the AMXP IGR J00291+5934 as observed with the Rossi X-ray Timing Explorer and XMM-Newton . We demonstrate that our method easily confirms the known coupling between the pulsations and a strong 8 mHz quasi-periodic oscillation (QPO) in XMM-Newton observations. Applying our method to the RXTE observations, we further show, for the first time, that the much weaker 20 mHz QPO and its harmonic are also coupled with the pulsations. We discuss the implications of this coupling and indicate how it may be used to extract new information on the underlying accretion process.

    A search for the decay Bs -> mu+mu- has been performed using proton-proton collisions recorded with the ATLAS detector at the LHC. The Standard Model predicts the time-integrated branching fraction for the decay to be extremely small. CLs tests method is used in extracting upper limit of the branching fraction from the experimental data. This report describes the two test methods used, the counting method and the mass fit method, and compares them.

By use of an optical parametric chirped-pulse amplification (OPCPA) preamplifier that is seeded by a cleaned high-energy pulse, a background amplified spontaneous emission (ASE) level of 10 -10 relative to the peak main femtosecond pulse on the picosecond timescales demonstrated with an output energy of 1.7 J and a pulse duration of 30 fs, corresponding to a peak power of 60TW at a 10 Hz repetition rate.

    XMMU J054134.7-682550, located in the LMC, featured a type II outburst in August 2007. We analyzed XMM-Newton (EPIC-MOS) and RXTE (PCA) data in order to derive the spectral and temporal characteristics of the system throughout the outburst. Spectral variability, spin period evolution, energy dependent pulse shape are discussed. The outburst (LX~3×1038 erg/s~LEDD) spectrum can be modeled using, cutoff power law, soft X-ray blackbody, disk emission, and cyclotron absorption line. The blackbody component shows a sinusoidal behavior, expected from hard X-ray reprocessing on the inner edge of the accretion disk. The thickness of the inner accretion disk (width of ~75 km) can be constrained. The spin-up of the pulsar during the outburst is the signature of a (huge) accretion rate. Simbol-X will provide similar capabilities as XMM-Newton and RXTE together, for such bright events.

    Biosorption of uranium by residual biomass from The Old Bushmill`s Distillery Co. Ltd., Bushmills, Co. Antrim, Northern Ireland, following exposure to short and intense electric pulses has been examined. The biomass was prepared from the distillery spent wash and consisted of non-viable yeast and bacterial cells. As shown previously, untreated biomass had a maximum biosorption capacity of 170 mg uranium/g dry weight biomass. When biosorption reactions were placed between two electrodes and exposed to electric pulses with field strengths ranging from 1.25-3.25 kV/cm at a capacitance of 25 {mu}F, biosorption increased from 170 mg of uranium to 275 mg uranium/g dry weight biomass. The data were obtained from biosorption isotherm analyses and taken as the degree of biosorption at residual uranium concentrations of 3 mM. In addition, when the capacitance of the electric pulses increased from 0.25 {mu}F to 25 {mu}F at a fixed pulse field strength the degree of biosorption increased from 210 mg uranium to 240 mg uranium/g dry weight biomass. The results suggest that application of short and intense electric pulses to biosorption reactions may play an important role in enhancing microbial biosorption of toxic metals/radionuclides from waste water streams.

    Production of prompt J/$\\psi$ meson pairs in proton-proton collisions at $\\sqrt{s}$ = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 inverse-femtobarns. The two J/$\\psi$ mesons are fully reconstructed via their decays into $\\mu^+\\mu^-$ pairs. This observation provides for the first time access to the high-transverse-momentum region of J/$\\psi$ pair production where model predictions are not yet established. The total and differential cross sections are measured in a phase space defined by the individual J/$\\psi$ transverse momentum ($p_T^{J/\\psi}$) and rapidity (|$y^{J/\\psi}$|): |$y^{J/\\psi}$| lower than 1.2 for $p_T^{J/\\psi}$ greater than 6.5 GeV/c; |$y^{J/\\psi}$| in [1.2,1.43] for a $p_T$ threshold that scales linearly with |$y^{J/\\psi}$| from 6.5 to 4.5 GeV/c; and |$y^{J/\\psi}$| in [1.43,2.2] for $p_T^{J/\\psi}$ greater than 4.5 GeV/c. The total cross section, assuming unpolarized prompt J/$\\psi$ pair production is 1.49 $\\pm$ 0.07...

    A diode-pumped laser amplifier model is derived from first principles and applied to a Nd:YAG amplifier operating on the {sup 4}F{sub 3/2} to {sup 4}I{sub 9/2} transition at 0.946 {mu}m. The effects of amplified spontaneous emission are included in the model and the addition of this effect is shown to produce better agreement with the data. The amplifier model includes effects of the transverse and longitudinal variation of the pump beam, transverse and longitudinal variation of the probe beam, and multiple passes of the probe beam. Experimental results obtained with a quasi four-level Nd:YAG amplifier operating at 0.946 {mu}m are used to validate the model. The amplifier was evaluated as a function of the pump energy, the probe energy, the probe beam radius, the pulse repetition frequency and the temperature. For all of the experimental conditions, the experimental results and the model agree.

    The LHCb experiment will study CP violation and rare B meson decays at the LHC accelerator, in the CERN laboratories of Geneva. The CP violation in the $b$ quark mesons was observed for the first time measuring the $\\sin2\\beta$ parameter. In the first year of data taking at LHCb the $\\sin2\\beta$ measurement will be performed in the channel $B_d ^0 \\rightarrow J/\\psi K_S ^0$ (called golden channel). The comparison with results obtained in previous experiments will show possible systematic errors. Once the systematic errors will be understood, the possible discrepancies with the expected results will be the sign of a new physics beyond the Standard Model. $\\sin2\\beta$ is extracted from the asymmetry in the decay $B_d ^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) K_S ^0 (\\pi^+\\pi^-)$ and its CP conjugated $\\overline{B}_d ^0 \\rightarrow J/\\psi(\\mu^-\\mu^+) K_S ^0(\\pi^-\\pi^+)$. To distinguish between $B_d ^0$ and $\\overline{B}_d$ flavour tagging algorithms are used. These introduce an additional parameter: the wrong tag fracti...

    AUTHOR|(SzGeCERN)655651; Vrba, Vaclav; Cerri, Alessandro; Palestini, Sandro

    Rare $B_s$ and $B_d$ meson decays into two muons are forbidden at the tree level of the Standard Model. They offer the opportunity to perform genuine probes of Yukawa interactions or Electroweak precision tests and play very important role to find signatures of physics beyond the Standard Model. A brief insight into the theoretical foundations of these decays is given in the introductory section, followed by a section with the ATLAS experiment description, none of which is directly a result of author's own work. The ATLAS Collaboration has been searching for $B_{(s)}^0 \\to \\mu^{+}\\mu^{-}$ decays using merged 2011 $\\sqrt{s} = 7$ TeV and 2012 $\\sqrt{s} = 8$ TeV Full Run I Data sample ($\\approx 25~fb^{-1}$). The analysis procedure has been firmly established and unblinding of the search region of $B_{(s)}^0 \\to \\mu^{+}\\mu^{-}$ is imminent. A sensitivity of the analysis to the $B_s^0 \\to \\mu^{+}\\mu^{-}$ signal is estimated to be $4.7~\\pm~1.0~\\sigma$. The description of the whole ATLAS $B_{(s)}^0 \\to \\mu^{+}\\mu^{-...

    The production of J/{psi} mesons in proton-proton collisions at {radical}(s)=7 {proportional_to} TeV is studied with the LHCb detector at the LHC. The differential cross-section for prompt J/{psi} production is measured as a function of the J/{psi} transverse momentum p{sub T} and rapidity y in the fiducial region p{sub T} in[0;14]{proportional_to}GeV mskip-2{mu} mskip-1mu c and y element of [2.0;4.5]. The differential cross-section and fraction of J/{psi} from b-hadron decays are also measured in the same p{sub T} and y ranges. The analysis is based on a data sample corresponding to an integrated luminosity of 5.2 pb{sup -1}. The measured cross-sections integrated over the fiducial region are for prompt J/{psi} production and for J/{psi} from b-hadron decays, where the first uncertainty is statistical and the second systematic. The prompt J/{psi} production cross-section is obtained assuming no J/{psi} polarisation and the third error indicates the acceptance uncertainty due to this assumption. (orig.)

  8. Search for the $B^0_d\\to\\mu^+\\mu^-$ decay and measurement of the $B^0_s\\to\\mu^+\\mu^-$ branching fraction and effective lifetime

    The search for new physics is the current aim of particle physics and might be pursued $\\textit{directly}$, by producing new possible particles in high energy collisions, or $\\textit{indirectly}$, by measurements of processes in which loops of new virtual particles might affect, for example, the decay rate. Being not limited by the collision energy, indirect searches are sensitive to particle masses which are larger than those accessible in direct searches. For this reason, indirect searches are a powerful tool to probe heavy particles that cannot be produced at colliders. The $B^0_{d,s}\\to\\mu^+\\mu^-$ decays are among the most sensitive probes to physics beyond the Standard Model. Such decays are extremely rare, occurring few times in billions of $B$ decays, due to loop and helicity suppressions. The decay probability is however precisely predicted in the Standard Model, as the purely leptonic final state allows to condensate hadronic interactions into a single constant. The search for $B^0_{d,s}\\to\\mu^+\\m...

    We consider the extension of the Minimal Supersymmetric Standard Model by Dirac masses for the gauginos. We study the possibility that the same singlet S that pairs up with the bino, to form a Dirac fermion, is used to generate {mu} and B{mu} terms through its vacuum expectation value. For this purpose, we assume that, in the Higgs potential, the necessary R-symmetry breaking originates entirely from a superpotential term ({kappa})/(3)S{sup 3} and discuss the implications for the spectrum of the model.

    The differential cross-section as a function of rapidity has been measured for the exclusive production of $J/\\psi$ and $\\psi(2S)$ mesons in proton-proton collisions at $\\sqrt{s}=7$ TeV, using data collected by the LHCb experiment, corresponding to an integrated luminosity of 930 pb$^{-1}$. The cross-sections times branching fractions to two muons having pseudorapidities between 2.0 and 4.5 are measured to be $$\\begin{array}{rl} \\sigma_{pp\\rightarrow J/\\psi\\rightarrow{\\mu^+}{\\mu^-}}(2.0<\\eta_{\\mu^\\pm }<4.5)=&291\\pm 7\\pm19 {\\rm \\ pb},\\\\ \\sigma_{pp\\rightarrow\\psi(2S)\\rightarrow{\\mu^+}{\\mu^-}}(2.0<\\eta_{\\mu^\\pm}<4.5)=&6.5\\pm 0.9\\pm 0.4 {\\rm \\ pb},\\end{array}$$ where the first uncertainty is statistical and the second is systematic. The measurements agree with next-to-leading order QCD predictions as well as with models that include saturation effects.

    A joint measurement is presented of the branching fractions $B^0_s\\to\\mu^+\\mu^-$ and $B^0\\to\\mu^+\\mu^-$ in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data samples were collected in 2011 at a centre-of-mass energy of 7 TeV, and in 2012 at 8 TeV. The combined analysis produces the first observation of the $B^0_s\\to\\mu^+\\mu^-$ decay, with a statistical significance exceeding six standard deviations, and the best measurement of its branching fraction so far, and three standard deviation evidence for the $B^0\\to\\mu^+\\mu^-$ decay. The measurements are statistically compatible with SM predictions and impose stringent constraints on several theories beyond the SM.

    A Ti : sapphire laser HAMA pumped by a diode-pumped solid-state laser (DPSSL) is developed to enable a high-repetitive inertial confinement fusion (ICF) experiment to be conducted. To demonstrate a counter-irradiation fast-heating fusion scheme, a 3.8 J, 0.4 ns amplified chirped pulse is divided into four beams: two counter-irradiate a target with intensities of 6 × 10 13 W cm −2 , and the remaining two are pulse-compressed to 110 fs for heating the imploded target with intensities of 2 × 10 17 W cm −2 . HAMA contributed to the first demonstration by showing that a 10 J class DPSSL is adaptable to ICF experiments and succeeded in DD neutron generation in the repetition mode. Based on HAMA, we can design and develop an integrated repetitive ICF experiment machine by including target injection and tracking. (paper)

    The evaluation of marginal microleakage in class V restorations of deciduous teeth prepared using Er:laser and comparison to the ones observed when conventionally prepared, using two photopolimerizable materials, composite resin and glass ionomer cement, was the subject of this study. Twenty eight complete deciduous teeth were divided into four groups Group 1 (G1) prepared with high speed drill + composite resin; Group 2 (G2) prepared with high speed drill + glass ionomer cement; Group 3 (G3) prepared using Er:YAG laser (2.94 {mu}m), 300 mJ, 3 Hz, handpiece 2051, energy density 86 mJ/cm{sup 2} + composite resin; Group 4 (G4) prepared using Er:YAG laser (2.94 {mu}m), 300 mJ, 3 Hz, handpiece 2051, energy density 86 J / cm{sup 2} + glass ionomer cement. After the preparation and restoration the specimens where stored at 37 deg C for 24 hours, thermally stressed, immersed in 50% aqueous solution of silver nitrate for 24 hours while kept in the dark. The specimens were rinsed in water, soaked in photodeveloping solution and exposed to fluorescent light for 6 hours. After this process the samples were sectioned and observed by stereomicroscopy. For comparison the groups were divided into occlusive and cervical microleakage. The results were analysed under the Kruskal-Wallis test. For the occlusive microleakage the statistical significance was 5% among the groups and the average comparison showed higher microleakage for G1 (M=35.1) than for G2 (M=24.0) as well as compared to G3 (M=22.3). The other groups did not present statistical differences among them. For the cervical microleakage the Kruskal-Wallis test did not present any statistical difference. Comparing the occlusive and cervical microleakage data, for every group, using the Wilcoxon test, no statistical differences were observed. Concluding, this study showed the Er:YAG laser to be effective for class V restorations and to result in a smaller microleakage degree using the composite resin. These results indicate

  16. Spatial distribution of ozone density in pulsed corona discharges observed by two-dimensional laser absorption method

    Ono, Ryo; Oda, Tetsuji [Department of Electrical Engineering, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-8656 (Japan)

    The spatial distribution of ozone density is measured in pulsed corona discharges with a 40 {mu}m spatial resolution using a two-dimensional laser absorption method. Discharge occurs in a 13 mm point-to-plane gap in dry air with a pulse duration of 100 ns. The result shows that the ozone density increases for about 100 {mu}s after the discharge pulse. The rate coefficient of the ozone-producing reaction, O + O{sub 2} + M {yields} O{sub 3} + M, is estimated to be 3.5 x 10{sup -34} cm{sup 6} s{sup -1}. It is observed that ozone is mostly distributed in the secondary-streamer channel. This suggests that most of the ozone is produced by the secondary streamer, not the primary streamer. After the discharge pulse, ozone diffuses into the background from the secondary-streamer channel. The diffusion coefficient of ozone is estimated to be approximately 0.1 to 0.2 cm{sup 2} s{sup -1}.

    We study the radiative leptonic decay, B{sup -}{yields}{mu}{sup -}{nu}{sub {mu}}{gamma}, in the framework of a relativistic independent quark model, based on the confining potential in the scalar-vector harmonic form. As expected, we find that the photon emission in this decay overcomes the so-called helicity suppression inevitable in the case of pure leptonic decay (B{sup -}{yields}{mu}{sup -}{nu}{sub {mu}}). Our result for the branching ratio is Br(B{sup -}{yields}{mu}{sup -}{nu}{sub {mu}}{gamma})=1.70x10{sup -6}, which is comparable with other model predictions within the current experimental upper limit. The photon energy spectrum predicted in the model is slightly asymmetric with the peak value around 1.45 GeV, which should render it quite accessible to experimental analysis.

    We report the first evidence for the decay Sigma(+)-->pmu(+)mu(-) from data taken by the HyperCP (E871) experiment at Fermilab. Based on three observed events, the branching ratio is B(Sigma(+)-->pmu(+)mu(-))=[8.6(+6.6)(-5.4)(stat)+/-5.5(syst)]x10(-8). The narrow range of dimuon masses may indicate that the decay proceeds via a neutral intermediate state, Sigma(+)-->pP(0),P0-->mu(+)mu(-) with a P0 mass of 214.3+/-0.5 MeV/c(2) and branching ratio B(Sigma(+)-->pP(0),P0-->mu(+)mu(-))=[3.1(+2.4)(-1.9)(stat)+/-1.5(syst)]x10(-8).

  20. Laser ablation of UHMWPE-polyethylene by 438 nm high energy pulsed laser

    Pulsed laser ablation of ultra-high-molecular-weight-polyethylene (UHMWPE) is investigated at Prague Asterix Laser System (PALS) Laboratory. The high ablation yield as a function of laser energy is presented at 438 nm laser wavelength. The mechanisms of the polymer ablation are studied on the base of ''in situ'' analysis, such as mass quadrupole spectrometry and time-of-flight measurements, and ''ex situ'' analysis, such as SEM investigations and Raman spectroscopy. Results show that the laser irradiation induces a strong polymer dehydrogenation and molecular emission due to different C{sub x}H{sub y} groups having high kinetic energy and high charge state. At a laser pulse energy of 150 J the H{sup +}, C{sup n+} ions (n=1 to 6) are emitted from the plasma with velocities of the order of 10{sup 8} cm/s, while the C{sub x}H{sub y} groups and the carbon clusters, detected up to C{sub 16}, have a velocity about one or two order magnitude lower. The laser ablation process produces a deep crater in the polymer, which depth depends on the laser pulse energy and it is of the order of 500 {mu}m. The crater volume increases with the laser pulse energy. Results demonstrated that the laser radiation modifies the polymer chains because dehydrogenated material and carbon-like structures are detected in the crater walls and in the bottom of the crater, respectively. A comparison of the experimental results with the data available in literature is presented and discussed.

  1. MuPAD tutorial

    CERN Document Server

    Creutzig, Christopher

    2004-01-01

    This book explains the basic use of the software package called MuPAD and gives an insight into the power of the system. MuPAD is a so-called com­ puter algebra system, which is developed mainly by Sciface Software and the MuPAD Research Group of the University of Paderborn in Germany. This introduction addresses mathematicians, engineers, computer scientists, natural scientists and, more generally, all those in need of mathematical com­ putations for their education or their profession. Generally speaking, this book addresses anybody who wants to use the power of a modern computer algebra package. There are two ways to use a computer algebra system. On the one hand, you may use the mathematical knowledge it incorporates by calling system functions interactively. For example, you can compute symbolic integrals or generate and invert matrices by calling appropriate functions. They comprise the system's mathematical intelligence and may implement sophisticated al­ gorithms. Chapters 2 through 15 discuss this...

    1994-10-13

    In the Large Electron Positron collider (LEP) bunches of electrons and positrons are brought in collision. At a collision energy of 91.2 GeV the Z resonance is excited. The Z boson, the uncharged mediator of the weak force, decays into a particle and an antiparticle almost instantaneously. The probability that in this process heavy quarks charm-anticharm(c anti c) and bottom-antibottom(b anti b) are formed is {approx}12% and {approx}15% respectively. Thus, LEP provides an ideal environment to make precision measurements in the heavy quark sector. The data for this thesis was collected with the L3 detector from 1990-1992. L3 is one of the four experiments at LEP. The integrated luminosity collected by L3 in this period is 43.5 pb{sup -1}. The L3 detector was designed to measure e{sup +}e{sup -} collisions up to 200 GeV with special emphasis on high resolution measurements of photons, electrons and muons. The detector is installed within a magnet providing 0.5 T field. It consists of subdetectors to detect and measure the direction and momentum/energy of charged particles, electromagnetic particles, hadrons and muons. In this thesis the production of the 1{sup 3} S{sub 1} (the j/{psi} meson) and the 2{sup 3} S{sub 1} (the {psi}` meson) and the c anti c bound states are investigated. The leptonic decays of the two mesons (J/{psi}, {psi}`{yields}l{sup +}l{sup -}, l=e, {mu}) provide the cleanest signals of heavy quarks. In this thesis, the {psi}` and J/{psi} mesons have been tagged via their decay into a muon pair. From the invariant mass distribution of the {mu}{sup +}{mu}{sup -} pairs the branching ratio for J/{psi} production at the Z, Br(Z{sup 0}{yields}J/{psi}+X), was determined to be 4.0{+-}0.6(stat.){+-}0.4(sys.)x10{sup -3} while the branching ratio for {psi}` production at the Z is smaller than <2x10{sup -3}.

    Ultraviolet laser light has several advantages in coupling with a laser fusion target, and the KrF laser is considered to be a promising candidate for the driver because of its short wavelength, high overall efficiency, and scalability to a megajoule class system. The Electrotechnical Laboratory is developing a 1-kJ class KrF laser system to perform target-shooting experiments in the 10/sup 13/-10/sup 15/-W/cm/sup 2/, 10-20-ns range and to investigate the possibility of a compact laser fusion driver which operates at a high pumping density and high laser power density. Based on the pulsed-power technology used in Amp2 and the characteristics of the Kr-rich mixture measured, Amp3 was designed to operate at high optical power density with a Kr-rich mixture. Amp3 has four PFLs charged by a single 40-kJ Marx generator and four e-beam diodes (550 kV, 4 Ω) arranged cylindrically around the laser cell. The active volume is 660 cm/sup 2/ (29 cm in diameter) X 1 m, and 2-atm Kr is pumped at a density of 1.9 MW/cm/sup 3/. Output energy of 1 kJ is expected at an intrinsic efficiency of 8.3% and overall efficiency of 2.5%. Output energy fluence is 1.5 J/cm/sup 2/ (15 MW/cm/sup 2/) on average, which is lower than the damage threshold of our fully reflecting AR coatings (>3 J/cm/sup 2/)

    A search is presented for hidden-sector bosons, $\\chi$, produced in the decay ${B^0\\!\\to K^*(892)^0\\chi}$, with $K^*(892)^0\\!\\to K^{+}\\pi^{-}$ and $\\chi\\!\\to\\mu^+\\mu^-$. The search is performed using $pp$-collision data corresponding to 3.0 fb$^{-1}$ collected with the LHCb detector. No significant signal is observed in the accessible mass range $214 \\leq m({\\chi}) \\leq 4350$ MeV, and upper limits are placed on the branching fraction product $\\mathcal{B}(B^0\\!\\to K^*(892)^0\\chi)\\times\\mathcal{B}(\\chi\\!\\to\\mu^+\\mu^-)$ as a function of the mass and lifetime of the $\\chi$ boson. These limits are of the order of $10^{-9}$ for $\\chi$ lifetimes less than 100 ps over most of the $m(\\chi)$ range, and place the most stringent constraints to date on many theories that predict the existence of additional low-mass bosons.

    We report the detection of pulsed gamma-ray emission from the fast millisecond pulsars (MSPs) B1937+21 (also known as J1939+2134) and B1957+20 (J1959+2048) using 18 months of survey data recorded by the Fermi Large Area Telescope (LAT) and timing solutions based on radio observations conducted at the Westerbork and Nancay radio telescopes. In addition, we analyzed archival RXTE and XMM-Newton X-ray data for the two MSPs, confirming the X-ray emission properties of PSR B1937+21 and finding evidence (approx. 4(sigma)) for pulsed emission from PSR B1957+20 for the first time. In both cases the gamma-ray emission profile is characterized by two peaks separated by half a rotation and are in close alignment with components observed in radio and X-rays. These two pulsars join PSRs J0034..0534 and J2214+3000 to form an emerging class of gamma-ray MSPs with phase-aligned peaks in different energy bands. The modeling of the radio and gamma-ray emission pro les suggests co-located emission regions in the outer magnetosphere.

    Conversion of thermal and cold neutrons into a strong {approx}1 ns electron pulse with an absolute neutron detection efficiency as high as 50-70% makes detectors with {sup 10}B-doped Microchannel Plates (MCPs) very attractive for neutron radiography and microtomography applications. The subsequent signal amplification preserves the location of the event within the MCP pore (typically 6-10 {mu}m in diameter), providing the possibility to perform neutron counting with high spatial resolution. Different event centroiding techniques of the charge landing on a patterned anode enable accurate reconstruction of the neutron position, provided the charge footprints do not overlap within the time required for event processing. The new fast 2 Multiplication-Sign 2 Timepix readout with >1.2 kHz frame rates provides the unique possibility to detect neutrons with sub-15 {mu}m resolution at several MHz/cm{sup 2} counting rates. The results of high resolution neutron radiography experiments presented in this paper, demonstrate the sub-15 {mu}m resolution capability of our detection system. The high degree of collimation and cold spectrum of ICON and BOA beamlines combined with the high spatial resolution and detection efficiency of MCP-Timepix detectors are crucial for high contrast neutron radiography and microtomography with high spatial resolution. The next generation of Timepix electronics with sparsified readout should enable counting rates in excess of 10{sup 7} n/cm{sup 2}/s taking full advantage of high beam intensity of present brightest neutron imaging facilities.

    Angular correlations in $B^+\\to X(3872) K^+$ decays, with $X(3872)\\to \\rho^0 J/\\psi$, $\\rho^0\\to\\pi^+\\pi^-$ and $J/\\psi \\to\\mu^+\\mu^-$, are used to measure orbital angular momentum contributions and to determine the $J^{PC}$ value of the $X(3872)$ meson. The data correspond to an integrated luminosity of 3.0 fb$^{-1}$ of proton-proton collisions collected with the LHCb detector. This determination, for the first time performed without assuming a value for the orbital angular momentum, confirms the quantum numbers to be $J^{PC}=1^{++}$. The $X(3872)$ is found to decay predominantly through S wave and an upper limit of $4\\%$ at $95\\%$ C.L. is set on the fraction of D wave.

  8. Measurement of the absolute branching fraction for Lambda(+)(c) -> Lambda mu(+)nu(mu)

    We report the first measurement of the absolute branching fraction for Lambda(+)(c) -> Lambda mu(+)nu(mu).This measurement is based on a sample of e+e(-) annihilation data produced at a center-of-mass energy root s = 4.6 GeV, collected with the BESIII detector at the BEPCII storage rings. The sample

  9. Phase-stable, multi-µJ femtosecond pulses from a repetition-rate tunable Ti:Sa-oscillator-seeded Yb-fiber amplifier

    We present a high-power, MHz-repetition-rate, phase-stable femtosecond laser system based on a phase-stabilized Ti:Sa oscillator and a multi-stage Yb-fiber chirped-pulse power amplifier. A 10-nm band around 1030 nm is split from the 7-fs oscillator output and serves as the seed for subsequent amplification by 54 dB to 80 W of average power. The µJ-level output is spectrally broadened in a solid-core fiber and compressed to 30 fs with chirped mirrors. A pulse picker prior to power amplification allows for decreasing the repetition rate from 74 MHz by a factor of up to 4 without affecting the pulse parameters. To compensate for phase jitter added by the amplifier to the feed-forward phase-stabilized seeding pulses, a self-referencing feed-back loop is implemented at the system output. An integrated out-of-loop phase noise of less than 100 mrad was measured in the band from 0.4 Hz to 400 kHz, which to the best of our knowledge corresponds to the highest phase stability ever demonstrated for high-power, multi-MHz-repetition-rate ultrafast lasers. This system will enable experiments in attosecond physics at unprecedented repetition rates, it offers ideal prerequisites for the generation and field-resolved electro-optical sampling of high-power, broadband infrared pulses, and it is suitable for phase-stable white light generation.

    Using the ATLAS detector, a centrality-dependent suppression has been observed in the yield of $J/{\\psi}$ mesons produced in the collisions of lead ions at the Large Hadron Collider. In a sample of minimum-bias lead-lead collisions at a nucleon-nucleon centre of mass energy $\\surd sNN$ = 2.76 TeV, corresponding to an integrated luminosity of about 6.7 ${\\mu}b^{-1}$, $J/{\\psi}$ mesons are reconstructed via their decays to ${\\mu}+{\\mu}-$ pairs. The measured $J/{\\psi}$ yield, normalized to the number of binary nucleon-nucleon collisions, is found to significantly decrease from peripheral to central collisions. The centrality dependence is found to be qualitatively similar to the trends observed at previous, lower energy experiments. The same sample is used to reconstruct Z bosons in the ${\\mu}+{\\mu}-$ final state, and a total of 38 candidates are selected in the mass window of 66 to 116 GeV. The relative Z yields as a function of centrality are also presented, although no conclusion can be inferred about their s...

    The production of $J/\\psi$ mesons in proton-proton collisions at a centre-of-mass energy of $\\sqrt{s}=13$ TeV is studied with the LHCb detector. Cross-section measurements are performed as a function of the transverse momentum $p_\\mathrm{T}$ and the rapidity $y$ of the $J/\\psi$ meson in the region $p_\\mathrm{T}<14 \\mathrm{GeV}/c$ and $2.0 < y < 4.5$, for both prompt $J/\\psi$ mesons and $J/\\psi$ mesons from $b$-hadron decays. The production cross-sections integrated over the kinematic coverage are $15.30\\pm 0.03\\pm 0.86$ $\\mu$b for prompt $J/\\psi$ and $2.34\\pm 0.01\\pm 0.13$ $\\mu$b for $J/\\psi$ from $b$-hadron decays, assuming zero polarization of the $J/\\psi$ meson. The first uncertainties are statistical and the second systematic. The cross-section reported for $J/\\psi$ mesons from $b$-hadron decays is used to extrapolate to a total $b\\bar{b}$ cross-section. The ratios of the cross-sections with respect to $\\sqrt{s}=8$ TeV are also determined.

    Short pulses with ultrahigh peak powers have been generated in Nd: glass and Alexandrite using the Chirped Pulse Amplification (CPA) technique. This technique has been successful in producing picosecond terawatt pulses with a table-top laser system. In the near future, CPA will be applied to large laser systems such as NOVA to produce petawatt pulses (1 kJ in a 1 ps pulse) with focused intensities exceeding 10/sup /plus/21/ W/cm 2 . These pulses will be associated with electric fields in excess of 100 e/a/sub o/ 2 and blackbody energy densities equivalent to 3 /times/ 10 10 J/cm 3 . This petawatt source will have important applications in x-ray laser research and will lead to fundamentally new experiments in atomic, nuclear, solid-state, plasma, and high-energy density physics. A review of present and future designs are discussed. 17 refs., 5 figs

    Two types of pulsed superconducting cables and four pulsed superconducting magnets have been developed in order to investigate basic problems in constructing ohmic heating coils of a tokamak-type fusion reactor. We found that a compacted cable is superior in mechanical rigidity and a braided cable is superior in cooling capacity as a conductor of a pulsed magnet. Stored energy and a maximum field of the magnets are 78 kJ and 6 T, 68 kJ and 4 T, 375 kJ and 6 T, and 363 kJ and 3 T, respectively. Some of these magnets quenched in pulsive operations due to excessive ac losses or macroscopic wire motions. Therefore, main conditions for operating pulsed magnets without quenching are (1) to make ac losses low enough to be cooled with liquid helium existing near at the conductor surface by reducing filament diameter to the order of 10 μm and utilizing CuNi as matrix effectively, and (2) to prevent macroscopic wire motions by partial solderfilling of a cable or winding a magnet with strong tension.

  15. Exploiting angular correlations in the rare decay $B\\rightarrow K^{*}\\mu^{+}\\mu^{-}$ at LHCb

    Reece, William Robert

    2010-01-01

    In this thesis, methods for studying the flavour-changing neutral current decay $B\\rightarrow K^{*}\\mu^{+}\\mu^{-}$ at LHCb are investigated. The decay proceeds via a $b\\rightarrow s$ loop, and will be sensitive to the effects of new particles, predicted in many models of beyond-the-Standard-Model physics. The formalism used to describe the decay will be introduced, and a number of observables available in its angular distribution presented. In the first few years of LHCb data taking, the number of signal events available will be relatively small and measurements must be optimized for experimental sensitivity. The vanishing point of the angular observable $S_{5}$ will be of particular interest; it has reduced theoretical uncertainties from hadronic form factors and can be extracted with high precision at LHCb. It provides a complementary measurement to that of $A_{FB}$ and $F_{L}$, already considered by BaBar, Belle, and CDF. Once $\\mathcal{O}(10^{4})$ $B\\rightarrow K^{*}\\mu^{+}\\mu^{-}$ signal events have been...

    Using $pp$ collision data collected by LHCb at center-of-mass energies $\\sqrt{s}$ = 7 TeV and 8 TeV, corresponding to an integrated luminosity of 3 fb$^{-1}$, the ratio of the branching fraction of the $B_c^+ \\rightarrow \\psi(2S)\\pi^+$ decay relative to that of the $B_c^+ \\rightarrow J/\\psi\\pi^+$ decay is measured to be 0.268 $\\pm$ 0.032 (stat) $\\pm$ 0.007 (syst) $\\pm$ 0.006 (BF). The first uncertainty is statistical, the second is systematic, and the third is due to the uncertainties on the branching fractions of the $J/\\psi \\rightarrow \\mu^+\\mu^-$ and $\\psi(2S) \\rightarrow \\mu^+\\mu^-$ decays. This measurement is consistent with the previous LHCb result, and the statistical uncertainty is halved.

    Previous in vitro studies have demonstrated that Ho:YLF laser is capable of inducing physical and chemical changes on dental surfaces treated for caries prevention. The temperature in the pulp chamber was in vitro evaluated to as a function of the power and frequency of the laser irradiation. The purpose of this work is to verify the occurrence of pulp inflammation after Ho:YLF laser irradiation using different parameters in rabbits' teeth. The premolars and molars of ten rabbits (NZB) were divided in two groups according to the irradiation energy values of a Ho:YLF laser prototype operating at 2.065{mu}m wave length, frequency of O,5Hz and pulse length of 250{mu}s. An group A teeth were irradiated with using ten pulses of 334mJ/pulse of a Ho:YLF laser prototype operating at O.5Hz, and group B, with 512mJ/pulse. Animals were killed by transcardiac perfusion and the samples were prepared for histopathological analysis. The in vitro temperature monitoring revealed an increase of 1 deg C for the 334mJ/pulse energy and 4.5 deg C for the 512mJ/pulse energy. SEM observations showed the occurrence of melting and resolidification in dental surface. From the in vivo analysis it can be concluded that both employed laser parameters did not induce to any inflammatory response from the pulp. (author)

    The prompt production of charmonium $\\chi_{c}$ and $J/\\psi$ states is studied in proton-proton collisions at a centre-of-mass energy of $\\sqrt{s}=7$ TeV at the Large Hadron Collider. The $\\chi_{c}$ and $J/\\psi$ mesons are identified through their decays $\\chi_{c}\\rightarrow J/\\psi \\gamma$ and $J/\\psi\\rightarrow \\mu^+\\mu^-$ using 36 pb$^{-1}$ of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for $\\chi_{c}$ and $J/\\psi$, $\\sigma (\\chi_{c}\\rightarrow J/\\psi \\gamma)/ \\sigma (J/\\psi)$, is determined as a function of the $J/\\psi$ transverse momentum in the range $2 < p_{\\mathrm T}^{J/\\psi} < 15$ GeV/$c$. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low $p_{\\mathrm T}^{J/\\psi}$ region.

    Highlights: Black-Right-Pointing-Pointer Ultra High Molecular Weight Polyethylene surface was modified with femtosecond laser pulses at 1027 nm wavelength. Black-Right-Pointing-Pointer Surface roughness is increased. Black-Right-Pointing-Pointer Ablation efficiency is maximum for 6 {mu}J pulses. Black-Right-Pointing-Pointer Irradiated surfaces remain almost chemically unaltered. - Abstract: Ultra-high-molecular-weight polyethylene (UHMWPE) is a polymer with mechanical and corrosion properties, which make it appropriate for using in biomedical devices such as hip and knee prostheses. The surface morphology and chemistry of UHMWPE influence its biocompatibility. A laser with wavelength at 1027 nm delivering 450 fs pulses at a repetition rate of 1 kHz is used to modify the surface of UHMWPE samples with 0.45 {mu}m root mean square surface roughness. Micrometric resolution is achieved with the use of a focusing lens of 0.25 NA and pulse energies of few microjoules. The study focuses in the influence of different pulse energies and pulse overlaps on the laser-induced surface roughness and ablation yield. Confocal microscopy is used to characterize changes in the morphology of the irradiated surfaces, and their chemical structure is analyzed by attenuated total reflectance infrared and Raman spectroscopies. The roughness increases as the pulse energy increases until it reaches a maximum. The ablation yield increases with the pulse energy and pulse overlap. However, the ablation yield per pulse is lower for higher pulse overlap. Pulses of 6 {mu}J have the highest ablation efficiency. Infrared and Raman spectra of samples irradiated with low energy pulses are similar to those of the pristine sample. However, some C=C and C=O bonds can be detected after irradiation with the highest pulse energies.

    Glutathione transferases (GSTs) comprise a major detoxification system in helminth parasites, displaying both catalytic and non-catalytic activities. The kinetic mechanism of these enzymes is complex and depends on the isoenzyme which is being analyzed. Here, we characterized the kinetic mechanism of rEgGST1, a recombinant form of a cytosolic GST from Echinococcus granulosus (EgGST1), which is related to the Mu-class of mammalian enzymes, using the canonical substrates glutathione (GSH) and 1-chloro-2,4-dinitrobenzene (CDNB). Initial rate and product inhibition studies were consistent with a steady-state random sequential mechanism, where both substrates are bound to the enzyme before the products are released. Kinetic constants were also determined (pH 6.5 and 30 °C). Moreover, rEgGST1 lowered the pK a of GSH from 8.71 ± 0.07 to 6.77 ± 0.08, and enzyme-bound GSH reacted with CDNB 1 × 10 5 times faster than free GSH at pH 7.4. Finally, the dissociation of the enzyme-GSH complex was studied by means of intrinsic fluorescence, as well as that of the complex with the anthelminth drug mebendazole. This is the first report on mechanistic issues related to a helminth parasitic GST. Copyright © 2017 Elsevier Inc. All rights reserved.

    An optical parametric amplifier that delivers nearly transform limited pulses is presented. The center wavelength of these pulses can be tuned between 993 nm and 1070 nm and, at the same time, the pulse duration is varied between 206 fs and 650 fs. At the shortest pulse duration the pulse energy was increased up to 7.2 microJ at 50 kHz repetition rate. Variation of the wavelength is achieved by applying a tunable cw seed while the pulse duration can be varied via altering the pump pulse duration. This scheme offers superior flexibility and scaling possibilities.

    We have performed a systematic study through particle-in-cell simulations to investigate the generation of attosecond pulse from relativistic laser plasmas when laser pulse duration approaches the few-cycle regime. A significant enhancement of attosecond pulse energy has been found to depend on laser pulse duration, carrier envelope phase, and plasma scale length. Based on the results obtained in this work, the potential of attaining isolated attosecond pulses with ∼100 μJ energy for photons >16 eV using state-of-the-art laser technology appears to be within reach

In this paper, we present the design and first test results of an LTD cavity that generates such a type of output pulse by including within its circular array a number of third harmonic bricks in addition to the main bricks. A voltage adder made out of a square pulse cavity linear array will produce the same shape output pulses provided that the timing of each cavity is synchronized with the propagation of the electromagnetic pulse.

    A small scale coupled Yb-silica and Tm-silica fibre laser system is described with output at 1.9 {mu}m and with Q-switching using an acousto-optic modulator and also by mechanical optical modulation. The Yb-fibre laser pump source exhibited strong self-pulsation with high-intensity pulses due to stimulated Brillouin scattering. But regular Q-switched pulses were generated from the Tm-fibre laser with an energy of {approx}2.4 {mu}J and duration (FWHM) of {approx}280 ns for modulation frequencies of 1-20 kHz when using acousto-optic modulation. The main effects that limit the Q-switched pulse peak power are the onset of gain-switched pulsing during the low-Q state and strong pump excited state absorption.

    Repetitively pulsed plasma jets generated by a capillary arc discharge at high stagnation pressure (>15,000 psi) and high temperature (>10,000 K) are utilized to produce 0.1-10 .mu.m sized metal powders and decrease cost of production. The plasma jets impact and atomize melt materials to form the fine powders. The melt can originate from a conventional melt stream or from a pulsed arc between two electrodes. Gas streams used in conventional gas atomization are replaced with much higher momentum flux plasma jets. Delivering strong incident shocks aids in primary disintegration of the molten material. A series of short duration, high pressure plasma pulses fragment the molten material. The pulses introduce sharp velocity gradients in the molten material which disintegrates into fine particles. The plasma pulses have peak pressures of approximately one kilobar. The high pressures improve the efficiency of disintegration. High gas flow velocities and pressures are achieved without reduction in gas density. Repetitively pulsed plasma jets will produce powders with lower mean size and narrower size distribution than conventional atomization techniques.

    2011-01-01

    We present a search for the Standard Model Higgs Boson using the process $ZH\\to\\mu^+\\mu^- b\\bar{b}$. We use a dataset corresponding to 9.2 fb$^{-1}$ of integrated luminosity from proton-antiproton collisions with center-of-mass energy 1.96 TeV at the Fermilab Tevatron, collected with the CDF II detector. This analysis benefits from several new multivariate techniques that have not been used in previous analyses at CDF. We use a multivariate function to select muon candidates, increasing signal acceptance while simultaneously keeping fake rates small. We employ an inclusive trigger selection to further increase acceptance. To enhance signal discrimination, we utilize a multi-layer approach consisting of expert discriminants. This multi-layer discriminant method helps isolate the two main classes of background events, $t\\bar{t}$ and $Z$+jets production. It also includes a flavor separator, to distinguish light flavor jets from jets consistent with the decay of a $B$-hadron. Wit h this novel multi-layer approach, we proceed to set limits on the $ZH$ production cross section times branching ratio. For a Higgs boson with mass 115 GeV/$c^2$, we observe (expect) a limit of 8.0 (4.9) times the Standard Model prediction.

The accelerator design is based on an architecture that is founded on three concepts: single-stage electrical-pulse compression, impedance matching, and transit-time-isolated drive circuits. The prime power source of the accelerator consists of 600 independent impedance-matched Marx generators. Each Marx comprises eight 5.8-GW bricks connected electrically in series, and generates a 100-ns 46-GW electrical-power pulse. A 450-ns-long water-insulated coaxial-transmission-line impedance transformer transports the power generated by each Marx to a system of twelve 2.5-m-radius water-insulated conical transmission lines. The conical lines are connected electrically in parallel at a 66-cm radius by a water-insulated 45-post sextuple-post-hole convolute. The convolute sums the electrical currents at the outputs of the conical lines, and delivers the combined current to a single solid-dielectric-insulated radial transmission line. The radial line in turn transmits the combined current to the load. Since much of the accelerator is water insulated, we refer to it as Neptune. Neptune is 40 m in diameter, stores 4.8 MJ of electrical energy in its Marx capacitors, and generates 28 TW of peak electrical power. Since the Marxes are transit-time isolated from each other for 900 ns, they can be triggered at different times to construct–over an interval as long as 1  μs–the specific load-current time history required for a given experiment. Neptune delivers 1 MJ and 20 MA in a 380-ns current pulse to an 18-mΩ load; hence Neptune is a megajoule-class 20-MA arbitrary waveform generator. Neptune will allow the international

    The J/{psi} decay angular distributions have been measured in inelastic photoproduction in ep collisions with the ZEUS detector at HERA, using an integrated luminosity of 468 pb{sup -1}. The range in photon-proton centre-of-mass energy, W, was 50J/{psi} mesons were identified through their decay into muon pairs. The polar and azimuthal angles of the {mu}{sup +} were measured in the J/{psi} rest frame and compared to theoretical predictions at leading and next-to-leading order in QCD. (orig.)

    We report the discovery of gamma-ray pulsations from the nearby isolated millisecond pulsar PSR J0030+0451 with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). This discovery makes PSR J0030+0451 the second millisecond pulsar to be detected in gamma-rays after PSR J0218+4232, observed by the EGRET instrument on the Compton Gamma Ray Observatory. The spin-down power (dot E) = 3.5 x 10 33 ergs s -1 is an order of magnitude lower than the empirical lower bound of previously known gamma-ray pulsars. The emission profile is characterized by two narrow peaks, respectively 0.07 ± 0.01 and 0.08 ± 0.02 wide, separated by 0.44 ± 0.02 in phase. The first gamma-ray peak falls 0.15 ± 0.01 after the main radio peak. The pulse shape is similar to that of the 'normal' gamma-ray pulsars. An exponentially cut-off power-law fit of the emission spectrum leads to an integral photon flux above 100 MeV of (6.76 ± 1.05 ± 1.35) x 10 -8 cm -2 s -1 with cut-off energy (1.7 ± 0.4 ± 0.5) GeV. Based on its parallax distance of (300 ± 90) pc, we obtain a gamma-ray efficiency L γ /(dot E) ≅ 15% for the conversion of spin-down energy rate into gamma-ray radiation, assuming isotropic emission.

    The determination of the differential branching fraction and the first angular analysis of the decay $B_s^0\\to\\phi\\mu^{+}\\mu^{-}$ are presented using data, corresponding to an integrated luminosity of $1.0\\,{\\rm fb}^{-1}$, collected by the LHCb experiment at $\\sqrt{s}=7\\,{\\rm TeV}$. The differential branching fraction is determined in bins of $q^{2}$, the invariant dimuon mass squared. Integration over the full $q^{2}$ range yields a total branching fraction of ${\\cal B}(B_s^0\\to\\phi\\mu^{+}\\mu^{-}) = (7.07\\,^{+0.64}_{-0.59}\\pm 0.17 \\pm 0.71)\\times 10^{-7}$, where the first uncertainty is statistical, the second systematic, and the third originates from the branching fraction of the normalisation channel. An angular analysis is performed to determine the angular observables $F_{\\rm L}$, $S_3$, $A_6$, and $A_9$. The observables are consistent with Standard Model expectations.

    The PhD thesis is dedicated to a study of heavy hadrons in the ATLAS experiment at the Large Hadron Collider. It presents a measurement of the branching ratios of the $B_c^+$ meson decays, $B_c^+\\to J/\\psi D_s^+$ and $B_c^+\\to J/\\psi D_s^{*+}$, using another $B_c^+$ decay, $B_c^+\\to J/\\psi \\pi^+$, for normalization. Polarization of daughter particles in the $B_c^+\\to J/\\psi D_s^{*+}$ decay is also measured. The study was performed with data collected by ATLAS in $pp$ collisions at centre-of-mass energies $\\sqrt{s} = 7$ and 8 TeV in 2011--2012. The thesis also describes a study on search for the $B^0_s\\to \\mu^+\\mu^-$ rare decay with ATLAS data of $pp$ collisions at $\\sqrt{s} = 7$~TeV. An upper limit on the decay branching ratio is set. Author's principal contribution to this study was developing a method to estimate a background from neutral $B$ meson decays to a pair of light charged hadrons ($B\\to hh^\\prime$).

  5. Surface mu heavy chain signals down-regulation of the V(D)J-recombinase machinery in the absence of surrogate light chain components.

    Early B cell development is characterized by stepwise, ordered rearrangement of the immunoglobulin (Ig) heavy (HC) and light (LC) chain genes. Only one of the two alleles of these genes is used to produce a receptor, a phenomenon referred to as allelic exclusion. It has been suggested that pre-B cell receptor (pre-BCR) signals are responsible for down-regulation of the VDJH-recombinase machinery (Rag1, Rag2, and terminal deoxynucleotidyl transferase [TdT]), thereby preventing further rearrangement on the second HC allele. Using a mouse model, we show that expression of an inducible muHC transgene in Rag2-/- pro-B cells induces down-regulation of the following: (a) TdT protein, (b) a transgenic green fluorescent protein reporter reflecting endogenous Rag2 expression, and (c) Rag1 primary transcripts. Similar effects were also observed in the absence of surrogate LC (SLC) components, but not in the absence of the signaling subunit Ig-alpha. Furthermore, in wild-type mice and in mice lacking either lambda5, VpreB1/2, or the entire SLC, the TdT protein is down-regulated in muHC+LC- pre-B cells. Surprisingly, muHC without LC is expressed on the surface of pro-/pre-B cells from lambda5-/-, VpreB1-/-VpreB2-/-, and SLC-/- mice. Thus, SLC or LC is not required for muHC cell surface expression and signaling in these cells. Therefore, these findings offer an explanation for the occurrence of HC allelic exclusion in mice lacking SLC components.

    A batch of 16 CsI(Tl) scintillator crystals, supplied by the Bicron Company, has been studied with respect to precise energy calibration in pulse-shape identification technique. The light corresponding to pulse integration within the time interval 1.6-4.5 mu s (long gate) and 0.0-4.5 mu s (extra-long gate) exhibits a power law relation, L(E,Z,A)=a1(Z,A)E sup a sup 2 sup ( sup Z sup , sup A sup ) , for sup 1 sup , sup 2 sup , sup 3 H isotopes in the measured energy range 5-150 MeV. For the time interval 0.0-0.60 mu s (short gate), a significant deviation from the power law relation is observed, for energy greater than approx 30 MeV. The character of the a2(p)-a2(d) and a2(p)-a2(t) correlations for protons, deuterons and tritons, reveals 3 types of crystals in the batch. These subbatches differ in the value of the extracted parameter a2 for protons, and in the value of the spread of a2 for deuterons and tritons. This may be explained by the difference in the energy dependence of the fast decay time component an...

  8. LHCb: Measurement of the time-dependent CP asymmetry in $B^{0} \\rightarrow J/\\psi K_S^0$

    CERN Multimedia

    Szilard, D

    2012-01-01

    The LHCb is one of the LHC experiments, specially designed to study CP violation and rare decays of b-quark. In this scenario, the decay $B^{0} \\rightarrow J/\\psi K_S^0$ is a well-known mode to study CP violation. The final state is the same for both CP eigenstates $B^0$ and $\\overline{B^0}$, which enables the interference through the b-quark oscillations.The CKM angle $\\beta$ can be extracted from the above decay. The time dependent decay rate asymmetry can be written as: $$ \\mathcal{A}_{J/\\psi K_S^0} (t) = S_{J/\\psi K_S^0} \\sin(\\Delta m_d t) - C_{J/\\psi K_S^0} \\cos( \\Delta m_d t) $$ where, in the standard model, the parameters $S_{J/\\psi K_S^0}$ and $C_{J/\\psi K_S^0}$ are connected to the CKM angle $\\beta$ through: $$S_{J/\\psi K_S^0} = \\sin 2 \\beta \\, \\rm{ and } \\, C_{J/\\psi K_S^0} = 0 $$ Here we report the time-dependent analysis in the $B^{0} \\rightarrow J/\\psi (\\mu^{+} \\mu^{-}) K_S^0 (\\pi^{+} \\pi^{-})$ decays. Using the $1fb^{-1}$ of integrated luminosity data collected in 2011 at LHCb operat...

  9. An angular analysis of $\\Lambda_b \\to \\Lambda \\mu^+ \\mu^-$ decays at the LHCb experiment.

    Everett, Christopher; Blake, Thomas

    This work presents an angular analysis of the suppressed $\\Lambda_b^0 \\rightarrow \\Lambda\\mu^+\\mu^-$ decay, performed using proton-proton collision data collected by the LHCb experiment during 2011 and 2012. The distribution of moments describing the decay with a non-zero transverse $\\Lambda_b^0$ baryon polarisation production are extracted for the first time, and used to determine the 5-dimensional angular distribution in the 15 to 20 GeV$^2/c^4$ dimuon invariant mass squared interval for the first time. The forward-backward asymmetry of the $\\Lambda$ baryon and $\\mu^+\\mu^-$ produced from the $\\Lambda_b^0$ baryon ($A_{FB}^{lh}$ ) is measured, along with the previously published $f_L$, $A^l_{FB}$ and $A^h_{FB}$. These values are found to be $f_L = 0.546 \\pm 0.132$, $A^l_{FB} = -0.004 \\pm 0.077$, $A^h_{FB} = -0.312 \\pm 0.150$ and $A_{FB}^{lh} = -0.007 ± 0.071$, where uncertainties are statistical, and account for correlation between the moments used to determine them.

    Highlights: • The power supply is required to have rapid rising and falling edges. • A modified topology based on the buck chopper of current-pulsed power supply is presented and analyzed. • An entity meeting the electrical requirements has been constructed. • The spike voltage of IGBT is qualitatively analyzed. - Abstract: This study presents the design and principle of a current-pulsed power supply (CPPS) for the tearing mode (TM) feedback control of the J-TEXT tokamak. CPPS is a new method of stabilizing large magnetic islands and accelerating mode rotation through the use of modulated magnetic perturbation. In this application, continuous magnetic perturbation pulse trains with frequency of 1 kHz to kHz, amplitude of 0.25 G, and duty ratio of 20%–50% are required generating via in-vessel magnetic coils. A modified topology based on buck chopper is raised to satisfy the demands of inductive load. This modified topology is characterized by high frequency, rapid rising and falling edges, and large amplitude of current pulses. Appropriate RCD snubber circuit is applied to protect the Insulated Gate Bipolar Transistor (IGBT) switch device. Equipment with peak current that reaches 1 kA, frequency that ranges from 1 kHz to 3 kHz, and rising and falling time within 100 μs was constructed and applied to physical experiment.

  14. Pulse power technology application to lasers

    International Nuclear Information System (INIS)

    Prestwich, K.R.

    1975-01-01

    Recent developments of intense relativistic electron beam accelerators and the associated pulse power technology are reviewed. The design of specific accelerators for gas laser excitation sources is discussed. A 3 MV, 800 kA, 24 ns electron beam accelerator under development for the electron beam fusion program is described along with the low jitter multichannel oil-dielectric rail switches developed for this application. This technology leads to the design of a 20 kJ, short pulse accelerator optimized gas laser excitation with radially converging electron beams. Other gas laser research requirements have led to the development of an accelerator that will produce a 0.5 MV, 20 kJ, 1 μs electron beam pulse. (auth)

    In order to measure the separate lifetimes of neutral and charged B hadrons, the data recorded in 1991 and 1992 by the LEP DELPHI experiment has been analyzed. B hadrons are identified using their decay into J/{psi}, followed by the decay of the latter into a muon pair. The performances of the detector allow to measure with a high precision the length of flight of the B in the R{phi} plane, as well as it momentum using a technique of jet-particle clustering, in which the J/{psi} is the nucleus. So the proper time is determined on an event by event basis. The estimation of the charge of the B hadrons is based on a discrimination method between the particles coming from their decay and those coming from the fragmentation process. After selection, 80 events allow to measure: {tau}{sub B}{sup 0} = 1.18{+-}0.38{+-}0.08 ps {tau}{sub B}{sup {+-}} 1.77{+-}0.37{+-}0.14 ps. (author). 92 refs., 75 figs., 24 tabs.

  16. Comparison of LIBS and {mu}-XRF measurements on bronze alloys for monitoring plasma effects

    The laser-induced breakdown spectroscopy (LIBS) technique is often used as atomic spectroscopic technique for elemental analysis of materials. However, it presents some drawbacks that make an accurate quantitative analysis difficult. Since the plasma properties, such as spatial inhomogeneity and plume stoichiometry strongly depend on the experimental conditions, the measurements are less reproducible. In order to evaluate the measurement fluctuations, we propose to use the more established micro X-Ray fluorescence ({mu}-XRF) technique for validating LIBS data. In particular, the quantitative data, obtained by varying the laser fluence, the shot numbers and the temporal acquisition parameters, were compared with those obtained by {mu}-XRF on laboratory made samples of binary, ternary and quaternary bronze alloys. For LIBS measurements a mobile double pulse laser instrument equipped with an high resolution Echelle type monochromator coupled to an intensified CCD camera was used. {mu}-XRF analyses were performed with a portable instrument that uses a micro collimated X-Ray beam and it is equipped with an high resolution detector. The LIBS results show a strong dependence both on the instrumental set up and the chemical-physical properties of the sample. With our findings we could identify the most suitable parameters to be used in the investigation of the different bronze alloys. The possibility to carry out a quantitative analysis by using the LIBS technique was checked through the comparison with related {mu}-XRF data. In particular in this paper we identified a set of reliable LIBS parameters for the quantitative analysis of copper, tin and zinc. Further analyses will be necessary to reach this goal also for the minor constituents as lead.

    The decay B0 -> J/psi K0_S is reconstructed with J/psi -> e+ e- or mu+ mu- and K0_S -> pi+ pi-. From the full ALEPH dataset at LEP1 of about 4 million hadronic Z decays, 23 candidates are selected with an estimated purity of 71%. They are used to measure the CP asymmetry of this decay, given by sin 2beta in the Standard Model, with the result sin 2beta = 0.84 +0.82-1.04 +-0.16. This is combined with existing measurements from other experiments, and increases the confidence level that CP violation has been observed in this channel to 98%.

  18. Communication: Rate coefficients from quasiclassical trajectory calculations from the reverse reaction: The Mu + H2 reaction re-visited

    In a previous paper [P. G. Jambrina et al., J. Chem. Phys. 135, 034310 (2011), 10.1063/1.3611400] various calculations of the rate coefficient for the Mu + H2 → MuH + H reaction were presented and compared to experiment. The widely used standard quasiclassical trajectory (QCT) method was shown to overestimate the rate coefficients by several orders of magnitude over the temperature range 200-1000 K. This was attributed to a major failure of that method to describe the correct threshold for the reaction owing to the large difference in zero-point energies (ZPE) of the reactant H2 and product MuH (˜0.32 eV). In this Communication we show that by performing standard QCT calculations for the reverse reaction and then applying detailed balance, the resulting rate coefficient is in very good agreement with the other computational results that respect the ZPE, (as well as with the experiment) but which are more demanding computationally.

    The prompt production of charmonium {chi}{sub c} and J/{psi} states is studied in proton-proton collisions at a centre-of-mass energy of {radical}(s)=7 TeV at the Large Hadron Collider. The {chi}{sub c} and J/{psi} mesons are identified through their decays {chi}{sub c}{yields}J/{psi}{gamma} and J/{psi}{yields}{mu}{sup +}{mu}{sup -} using 36 pb{sup -1} of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for {chi}{sub c} and J/{psi}, {sigma}({chi}{sub c}{yields}J/{psi}{gamma})/{sigma}(J/{psi}), is determined as a function of the J/{psi} transverse momentum in the range 2J/{psi}}<15 GeV/c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p{sub T}{sup J/{psi}} region.

The analysis is based on an integrated luminosity of 360 pb{sup -1} in p{bar p} collisions collected by the Collider Detector at Fermilab. We observe 18.9 {+-} 5.7 signal events on a background of 10.0 {+-} 1.4 events and the fit to the J/{psi}{pi}{sup {+-}} mass spectrum yields a B{sub c}{sup {+-}} mass of 6287.0 {+-} 4.8(stat) {+-} 1.1(syst) MeV/c{sup 2}.

    Beam halo scraping schemes have been explored in the 50 x 50 GeV and 2 x 2 TeV {mu}{sup +}{mu}{sup -} colliders using both absorbers and electrostatic deflectors. Utility sections have been specially designed into the rings for scraping. Results of realistic STRUCT- MARS Monte-Carlo simulations show that for the low-energy machine a scheme with a 5 m long steel absorber suppresses losses in the interaction region by three orders of magnitude. The same scraping efficiency at 2 TeV is achieved only by complete extraction of beam halo from the machine. The effect of beam-induced power dissipation in the collider superconducting magnets and detector backgrounds is shown both for the first few turns after injection and for the rest of the cycle.

    An increased pulse pressure (difference between systolic and diastolic blood pressure) suggests aortic stiffening. The objective of this study was to examine the acute effects of both particulate matter (PM) mass and composition on blood pressure, among elderly persons. We carried out a panel study in persons living in elderly homes in Antwerp, Belgium. We recruited 88 non-smoking persons, 70% women with a mean age of 83 years (standard deviation: 5.2). Blood pressure was measured and a blood sample was collected on two time points, which were chosen so that there was an exposure contrast in ambient PM exposure. The elemental content of the collected indoor and outdoor PM{sub 2.5} (particulate matter with an aerodynamic diameter <2.5 {mu}m) mass concentration was measured. Oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) on outdoor PM{sub 10} (particulate matter with an aerodynamic diameter <10 {mu}m) were measured. Each interquartile range increase of 20.8 {mu}g/m Superscript-Three in 24-h mean outdoor PM{sub 2.5} was associated with an increase in pulse pressure of 4.0 mmHg (95% confidence interval: 1.8-6.2), in persons taking antihypertensive medication (n=57), but not in persons not using antihypertensive medication (n=31) (p for interaction: 0.02). Vanadium, iron and nickel contents of PM{sub 2.5} were significantly associated with systolic blood pressure and pulse pressure, among persons on antihypertensive medication. Similar results were found for indoor concentrations. Of the oxy-PAHs, chrysene-5,6-dione and benzo[a]pyrene-3,6-dione were significantly associated with increases in systolic blood pressure and pulse pressure. In elderly, pulse pressure was positively associated with acute increases in outdoor and indoor air pollution, among persons taking antihypertensive medication. These results might form a mechanistic pathway linking air pollution as a trigger of cardiovascular events.

    Much work has been done on opioid systems in the rat CNS. Although the mouse is widely used in pharmacological studies of opioid action, little has been done to characterize opioid systems in this species. In the present study the distribution of mu and delta opioid binding sites in the mouse CNS was examined using a quantitative in vitro autoradiography procedure. Tritiated dihydromorphine was used to visualize mu sites and [3H-d-Ala2-d-Leu5]enkephalin with a low concentration of morphine was used to visualize delta sites. Mu and delta site localizations in the mouse are very similar to those previously described in the rat (Goodman, R.R., S.H. Snyder, M.J. Kuhar, and W.S. Young, 3d (1980) Proc. Natl. Acad. Sci. U.S.A. 77:6239-6243), with certain exceptions and additions. Mu and delta sites were observed in sensory processing areas, limbic system, extrapyramidal motor system, and cranial parasympathetic system. Differential distributions of mu and delta sites were noted in many areas. Mu sites were prominent in laminae I, IV, and VI of the neocortex, in patches in the striatum, and in the ventral pallidum, nucleus accumbens, medial and midline thalamic nuclei, medial habenular nucleus, interpeduncular nucleus, and laminae I and II of the spinal cord. In contrast, delta sites were prominent in all laminae of the neocortex, olfactory tubercle, diffusely throughout the striatum, and in the basal, lateral, and cortical nuclei of the amygdala. The determination of the differential distributions of opioid binding sites should prove useful in suggesting anatomical substrates for the actions of opiates and opioids

    The generation of small sub-pulses in the delayed-interference signal-wavelength converter (DISC), which has been studied for use in future 160-Gb/s optical time division multiplexing-wavelength division multiplexing (OTDM-WDM) communication systems, was recently predicted as a potential problem....... In this work, we have experimentally verified the generation of such pulses and its mechanism. In the experiments we used 3.8-ps-long 1.56-mu m input pulses with repetition frequencies from 12.5 to 25.0 GHz and a cross-correlation monitoring system with a time resolution of approximately 2 ps....

The resulting value of B( tau /sup -/ to mu /sup -/ nu /sub mu / nu /sub tau /) = 0.1734 +or- 0.0009 (stat) +or- 0.0006(syst) has been used in conjunction with other OPAL measurements to test lepton universality, yielding the coupling constant ratios g/sub mu //g/sub e/ = 1.0005 +or- 0.0044 and g/sub tau //g/sub e/ = 1.0031 +or- 0.0048, in good agreement with the Standard Model prediction of unity. A value for the Michel parameter eta = 0.004 +or- 0.037 has also been determined and used to find a limit for the mass of the charged Higgs boson, m/sub H/+or- > 1.28 tan beta , in the minimal supersymmetric standard model.

    Alterations in a variety of neurotransmitter systems have been identified in experimental models of epilepsy and in brain tissue from patients with intractable temporal lobe seizures. The availability of new high-affinity radioligands permits the study of some neuroreceptors in vivo with positron emission tomography (PET). We previously characterized the in vivo binding of 11C-carfentanil, a potent and selective mu opiate receptor agonist, and described increases in 11C-carfentanil binding in the temporal neocortex of patients with unilateral temporal lobe epilepsy. These studies have been extended to 11C-diprenorphine, which labels mu, kappa, and delta opiate receptor subtypes. Paired measurements of opiate receptor binding were performed with PET using 11C-carfentanil and 11C-diprenorphine in patients with unilateral temporal lobe seizures. Carfentanil binding, reflecting changes in mu opiate receptors, was increased in the temporal neocortex and decreased in the amygdala on the side of the epileptic focus. Diprenorphine binding, reflecting mu as well as non-mu opiate subtypes, was not significantly different among regions in the focus and nonfocus temporal lobes. Regional glucose metabolism, measured using 18F-2-fluoro-2-deoxyglucose, was decreased in the mesial and lateral aspects of the temporal lobe ipsilateral to the epileptogenic focus. The variation in pattern of carfentanil and diprenorphine binding supports a differential regulation of opiate subtypes in unilateral temporal lobe epilepsy.

    A measurement of $J/\\psi$ and $\\psi(2\\mathrm{S})$ production is presented. It is based on a data sample from Pb+Pb collisions at $\\sqrt{s_{\\mathrm{NN}}}$ = 5.02 TeV and $pp$ collisions at $\\sqrt{s}$ = 5.02 TeV recorded by the ATLAS detector at the LHC in 2015, corresponding to an integrated luminosity of 0.42 nb$^{-1}$ and 25 pb$^{-1}$ in Pb+Pb and $pp$, respectively. The measurements of per-event yields, nuclear modification factors, and non-prompt fractions are performed in the dimuon decay channel for $9 < p_{T}^{\\mu\\mu} < 40$ GeV in dimuon transverse momentum, and $-2.0 < y_{\\mu\\mu} < 2.0$ in rapidity. Strong suppression is found in Pb+Pb collisions for both prompt and non-prompt $J/\\psi$, as well as for prompt and non-prompt $\\psi(2\\mathrm{S})$, increasing with event centrality. The suppression of prompt $\\psi(2\\mathrm{S})$ is observed to be stronger than that of $J/\\psi$, while the suppression of non-prompt $\\psi(2\\mathrm{S})$ is equal to that of the non-prompt $J/\\psi$ within uncertainties,...

    The Mu2e experiment at Fermilab will search for charged lepton flavor violation via the coherent conversion process mu- N --> e- N with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process. The experiment's sensitivity offers discovery potential over a wide array of new physics models and probes mass scales well beyond the reach of the LHC. We describe herein the preliminary design of the proposed Mu2e experiment. This document was created in partial fulfillment of the requirements necessary to obtain DOE CD-2 approval.

  9. High power ultrashort pulse lasers

    Small scale terawatt and soon even petawatt (1000 terawatt) class laser systems are made possible by application of the chirped-pulse amplification technique to solid-state lasers combined with the availability of broad bandwidth materials. These lasers make possible a new class of high gradient accelerators based on the large electric fields associated with intense laser-plasma interactions or from the intense laser field directly. Here, we concentrate on the laser technology to produce these intense pulses. Application of the smallest of these systems to the production of high brightness electron sources is also introduced

    We demonstrate high-energy infrared femtosecond pulse generation by a dual-chirped optical parametric amplification (DC-OPA) scheme [Opt. Express19, 7190 (2011)]. By employing a 100 mJ pump laser, a signal pulse energy exceeding 20 mJ at a wavelength of 1.4 μm was achieved before dispersion compensation. A total output energy of 33 mJ was recorded. Under a further energy scaling condition, the signal pulse was compressed to an almost transform-limited duration of 27 fs using a fused silica prism compressor. Since the DC-OPA scheme is efficient and energy scalable, design parameters for obtaining 100 mJ level infrared pulses are presented, which are suitable as driver lasers for the energy scaling of high-order harmonic generation with sub-keV photon energy.

    An optical injection scheme for a laser-plasma based accelerator which employs a non-collinear counter-propagating laser beam to push background electrons in the focusing and acceleration phase via ponderomotive beat with the trailing part of the wakefield driver pulse is discussed. Preliminary experiments were performed using a drive beam of a 0 = 2.6 and colliding beam of a 1 = 0.8 both focused on the middle of a 200 mu m slit jet backed with 20 bar, which provided ∼ 260 mu m long gas plume. The enhancement in the total charge by the colliding pulse was observed with sharp dependence on the delay time of the colliding beam. Enhancement of the neutron yield was also measured, which suggests a generation of electrons above 10 MeV

    We report on the deposition of nanostructured porphyrin-base, 5(4-carboxyphenyl)-10,15,20-tris(4-phenoxyphenyl)-porphyrin thin films by matrix assisted pulsed laser evaporation onto silicon substrates with screen-printed electrodes. AFM investigations have shown that at 400 mJ/cm{sup 2} fluence a topographical transition takes place from the platelet-like stacking porphyrin-based nanostructures in a perpendicular arrangement to a quasi-parallel one both relative to the substrate surface. Raman spectroscopy has shown that the chemical structure of the deposited thin films is preserved for fluences within the range of 200–300 mJ/cm{sup 2}. Cyclic voltammograms have demonstrated that the free porphyrin is appropriate as a single mediator for glucose in a specific case of screen-printed electrodes, suggesting potential for designing a new class of biosensors.

    Measurements are reported of the central exclusive production of $J/\\psi$ and $\\psi(2S)$ mesons in $pp$ collisions at a centre-of-mass energy of 13$\\ \\rm {TeV}$. Backgrounds are significantly reduced compared to previous measurements made at lower energies through the use of new forward shower counters. The products of the cross-sections and the branching fractions for the decays to dimuons, where both muons are within the pseudorapidity range $2.0<\\eta<4.5$, are measured to be $$ \\begin{array}{rcl} \\sigma_{J/\\psi\\rightarrow\\mu^+\\mu^-}&=&399 \\pm 16 \\pm 10 \\pm 16 {\\rm \\ pb},\\\\ \\sigma_{\\psi(2S)\\rightarrow\\mu^+\\mu^-}&=&10.2 \\pm 1.0 \\pm 0.3 \\pm 0.4 {\\rm \\ pb}.\\\\ \\end{array} $$ The first uncertainties are statistical, the second are systematic, and the third are due to the luminosity determination. The cross-sections are also measured differentially for meson rapidities between 2.0 and 4.5. Good agreement is observed with theoretical predictions. Photoproduction cross-sections are derived ...

    We report the first evidence for a fully reconstructed decay mode of the B(c)+- meson in the channel B(c)+- --> J/psi pi+-, with J/psi --> mu+ mu-. The analysis is based on an integrated luminosity of 360 pb(-1) in pp collisions at 1.96 TeV center of mass energy collected by the Collider Detector at Fermilab. We observe 14.6 +/- 4.6 signal events with a background of 7.1 +/- 0.9 events, and a fit to the J/psi pi+-mass spectrum yields a B(c)+- mass of 6285.7 +/- 5.3(stat) +/- 1.2(syst) MeV/c2. The probability of a peak of this magnitude occurring by random fluctuation in the search region is estimated as 0.012%.

    Diabetic neuropathy is a prevalent, disabling disorder. Currently, the only treatments available to patients with diabetic neuropathy are glucose control and pain management. B vitamin present neuroprotective effects, which are suggested to be related to their analgesic action in various models of neuropathic pain. According to our literature knowledge there is no report about antinociceptive effects of thiamine as benfotiamine and opioids together in diabetic mice. The purpose of this study was to determine the effects of benfotiamine on the antinociception produced by mu-opioid receptor agonist fentanyl in diabetic mice. The effects of benfotiamine on antinociception produced by fentanyl in diabetic mice were studied in 4 groups. Antinociceptive effect was determined with tail flick, hot plate and formalin test. Our results showed that, mu-opioid agonist fentanyl in benfotiamine applied diabetic group caused more potent antinociceptive effect than in diabetic group without benfotiamine treatment. In brief benfotiamine supplement in diet did not bring out antinociceptive effect itself, but during development of STZ diabetes, benfotiamine replacement increased the antinociceptive effect of fentanyl in mice tail-flick test. This effect is probably due to the replacement of benfotiamine efficiency occurring in diabetes mellitus. Finally, we suppose that oral benfotiamine replacement therapy may be useful to ameliorate analgesic effect of mu-opioid agonists on neuropathic pain in diabetic case. © J. A.

    Inclusive J/$\\psi$ production has been studied with the ALICE detector in p-Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV at the CERN LHC, in the rapidity domains 2.03 < y$_{cms}$ < 3.53 and −4.46 < y$_{cms}$ < −2.96, down to zero transverse momentum. The J/$\\psi$ measurement is performed in the Muon Spectrometer through the $\\mu^+\\mu^−$ decay mode. In this Letter, the J/$\\psi$ production cross section and the nuclear modification factor R$_{pPb}$ for the rapidities under study are presented. While at forward rapidity a suppression of the J/$\\psi$ yield with respect to binary-scaled pp collisions is observed, in the backward region no suppression is present. The ratio of the forward and backward yields is also shown differentially in rapidity and transverse momentum. Theoretical predictions based on nuclear shadowing, as well as on models including, in addition, a contribution from partonic energy loss, are in fair agreement with the experimental results.

    Research highlights: {yields} Trafficking defect of kAE1 is a cause of dRTA but trafficking pathway of kAE1 has not been clearly described. {yields} Adaptor-related protein complex 1 {mu}1A (AP-1 mu1A) was firstly reported to interact with kAE1. {yields} The interacting site for AP-1 mu1A on Ct-kAE1 was found to be Y904DEV907, a subset of YXXO motif. {yields} AP-1 mu1A knockdown showed a marked reduction of kAE1 on the cell membrane and its accumulation in endoplasmic reticulum. {yields} AP-1 mu1A has a critical role in kAE1 trafficking to the plasma membrane. -- Abstract: Kidney anion exchanger 1 (kAE1) mediates chloride (Cl{sup -}) and bicarbonate (HCO{sub 3}{sup -}) exchange at the basolateral membrane of kidney {alpha}-intercalated cells. Impaired trafficking of kAE1 leads to defect of the Cl{sup -}/HCO{sub 3}{sup -} exchange at the basolateral membrane and failure of proton (H{sup +}) secretion at the apical membrane, causing a kidney disease - distal renal tubular acidosis (dRTA). To gain a better insight into kAE1 trafficking, we searched for proteins physically interacting with the C-terminal region of kAE1 (Ct-kAE1), which contains motifs crucial for intracellular trafficking, by a yeast two-hybrid (Y2H) system. An adaptor-related protein complex 1 {mu}1A (AP-1 mu1A) subunit was found to interact with Ct-kAE1. The interaction between either Ct-kAE1 or full-length kAE1 and AP-1 mu1A were confirmed in human embryonic kidney (HEK) 293T by co-immunoprecipitation, affinity co-purification, co-localization, yellow fluorescent protein (YFP)-based protein fragment complementation assay (PCA) and GST pull-down assay. The interacting site for AP-1 mu1A on Ct-kAE1 was found to be Y904DEV907, a subset of YXXO motif. Interestingly, suppression of endogenous AP-1 mu1A in HEK 293T by small interfering RNA (siRNA) decreased membrane localization of kAE1 and increased its intracellular accumulation, suggesting for the first time that AP-1 mu1A is involved in the kAE1

    MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI were more resistant to Cd than wild-type cells transfected with vector alone. MuSI transgenic plants were also more resistant to Cd. MuSI t...

    Mu2e at Fermilab will search for charged lepton flavor violation via the coherent conversion process mu- N → e- N with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process. The experiment's sensitivity offers discovery potential over a wide array of new physics models and probes mass scales well beyond the reach of the LHC. We describe herein the conceptual design of the proposed Mu2e experiment. This document was created in partial fulfillment of the requirements necessary to obtain DOE CD-1 approval, which was granted July 11, 2012.

  20. Measurement of inelastic J/{psi} production in deep inelastic ep scattering at HERA

    This thesis presents a measurement of the inelastic production of J/{psi} mesons in ep collisions with the ZEUS detector at HERA using an integrated luminosity of 109 pb{sup -1}. The J/{psi} mesons were identified using the decay channel J/{psi} {yields} {mu}{sup +}{mu}{sup -}. The measurements were performed in the kinematic range 2J/{psi} meson in the proton rest frame and Y{sub lab} is the rapidity of the J/{psi} in the laboratory frame. The measured cross sections are compared to theoretical predictions within the non-relativistic QCD framework including colour-singlet and colour-octet contributions, as well as to predictions based on the k{sub T}-factorisation approach. Calculations of the colour-singlet process generally agree with the data, whereas inclusion of colour-octet terms spoils this agreement. As a technical part of this thesis, the Straw-Tube Tracker (STT) GEANT simulation and track reconstruction software developed. Studies of the STT performance with MC data and real data presented.

    Using the $pp$ collision data collected by LHCb at center-of-mass energies $\\sqrt{s} \\, = 7 \\, {\\rm TeV} \\,$ and $8 \\, {\\rm TeV} \\,$, corresponding to an integrated luminosity of $3 \\, \\mathrm{fb}^{-1} \\,$, the ratio of the branching fraction of the $B_{c}^{+} \\to \\psi(2S)\\pi^+$ decay relative to that of the $B_{c}^{+} \\to J/\\psi\\pi^+$ decay is measured to be ${0.268 \\pm 0.032\\mathrm{\\,(stat)} \\pm 0.007\\mathrm{\\,(syst)} \\pm 0.006\\,(\\mathrm{BF}) }$. The first uncertainty is statistical, the second is systematic, and the third is due to the uncertainties on the branching fractions of the $J/\\psi \\to \\mu^{+}\\mu^{-}$ and $\\psi(2S) \\to \\mu^{+}\\mu^{-}$ decays. To enhance the signal significance with limited $B_{c}^{+}$ statistics, the boosted decision tree selection is used to separate the signal and background effectively. The systematic uncertainties are discussed extensively. This measurement is consistent with the previous LHCb result, and the statistical uncertainty is halved.

  2. Mu rhythm desynchronization by tongue thrust observation

    Full Text Available We aimed to investigate the mu rhythm in the sensorimotor area during tongue thrust observation and to obtain an answer to the question as to how subtle non-verbal orofacial movement observation activates the sensorimotor area. Ten healthy volunteers performed finger tap execution, tongue thrust execution, and tongue thrust observation. The electroencephalogram was recorded from 128 electrodes placed on the scalp, and regions of interest were set at sensorimotor areas. The event-related desynchronization (ERD and event-related synchronization (ERS for the mu rhythm (8–13 Hz and beta (13−25 Hz bands were measured. Tongue thrust observation induced mu rhythm ERD, and the ERD was detected at the left hemisphere regardless whether the observed tongue thrust was toward the left or right. Mu rhythm ERD was also recorded during tongue thrust execution. However, temporal analysis revealed that the ERD associated with tongue thrust observation preceded that associated with execution by approximately 2 s. Tongue thrust observation induces mu rhythm ERD in sensorimotor cortex with left hemispheric dominance.

    Modern high energy physics experiments have to process terabytes of input data produced in particle collisions. The core of the data reconstruction in high energy physics is the Kalman filter. Therefore, developing the fast Kalman filter algorithm, which uses maximum available power of modern processors, is important, in particular for initial selection of events interesting for the new physics. One of processors features, which can speed up the algorithm, is a SIMD instruction set, which allows to pack several data items in one register and operate on all of them in one go, thus achieving more operations per clock cycle. Therefore a flexible and useful interface, which uses the SIMD instruction set on different CPU and GPU processors architectures, has been realized as a vector classes library. The Kalman filter based track fitting algorithm has been implemented with use of the vector classes. Fitting quality tests show good results with the residuals equal to 49 {mu}m and 44 {mu}m for x and y track parameters and relative momentum resolution of 0.7%. The fitting time of 0.053 {mu}s per track has been achieved on Intel Xeon X5550 with 8 cores at 2.6 GHz by using in addition Intel Threading Building Blocks.

    Advanced Radiographic Capability (ARC) project at the National Ignition Facility (NIF) is designed to produce energetic, ultrafast x-rays in the range of 70-100 keV for backlighting NIF targets. The chirped pulse amplification (CPA) laser system will deliver kilo-Joule pulses at an adjustable pulse duration from 1 ps to 50 ps. System complexity requires sophisticated simulation and modeling tools for design, performance prediction, and comprehension of experimental results. We provide a brief overview of ARC, present our main modeling tools, and describe important performance predictions. The laser system (Fig. 1) consists of an all-fiber front end, including chirped-fiber Bragg grating (CFBG) stretchers. The beam after the final fiber amplifier is split into two apertures and spatially shaped. The split beam first seeds a regenerative amplifier and is then amplified in a multi-pass Nd:glass amplifier. Next, the preamplified chirped pulse is split in time into four identical replicas and injected into one NIF Quad. At the output of the NIF beamline, each of the eight amplified pulses is compressed in an individual, folded, four-grating compressor. Compressor grating pairs have slightly different groove densities to enable compact folding geometry and eliminate adjacent beam cross-talk. Pulse duration is adjustable with a small, rack-mounted compressor in the front-end. We use non-sequential ray-tracing software, FRED for design and layout of the optical system. Currently, our FRED model includes all of the optical components from the output of the fiber front end to the target center (Fig. 2). CAD designed opto-mechanical components are imported into our FRED model to provide a complete system description. In addition to incoherent ray tracing and scattering analysis, FRED uses Gaussian beam decomposition to model coherent beam propagation. Neglecting nonlinear effects, we can obtain a nearly complete frequency domain description of the ARC beam at different stages

    International audience; In histotripsy, soft tissues can be fragmented using very high pressure ultrasound pulses. Using time-reversal cavity is a way to generate high pressure pulses with a limited number of acoustic sources. The principle was already demonstrated by Montaldo et al. using a solid metal cavity, but low transmission coefficient was obtained due to the strong impedance mismatch at the metal/water interface. We propose here to use a waveguide filled with water containing a 2D mu...

    Pulse experiments have been performed at J. Stefan Institute TRIGA reactor since 1991. In total, more than 130 pulses have been performed. Extensive experimental information on the pulse physical characteristics has been accumulated. Fuchs-Hansen adiabatic model has been used for predicting and analysing the pulse parameters. The model is based on point kinetics equation, neglecting the delayed neutrons and assuming constant inserted reactivity in form of step function. Deficiencies of the Fuchs-Hansen model and systematic experimental errors have been observed and analysed. Recently, the pulse model was improved by including the delayed neutrons and time dependence of inserted reactivity. The results explain the observed non-linearity of the pulse energy for high pulses due to finite time of pulse rod withdrawal and the contribution of the delayed neutrons after the prompt part of the pulse. The results of the improved model are in good agreement with experimental results. (author)

    We report on the first 180 days of Rossi X-Ray Timing Explorer observations of the outburst of the black hole candidate IGR Jl7091-3624. This source exhibits a broad variety of complex light curve patterns including periods of strong flares alternating with quiet intervals. Similar patterns in the X-ray light curves have been seen in the (up to now) unique black hole system GRS 1915+105. In the context of the variability classes defined by Belloni et al. for GRS 1915+105, we find that JGR J17091-3624 shows the nu, rho, alpha, lambda, Beta, and mu classes as well as quiet periods which resemble the chi class, all occurring at 2-60 keY count rate levels which can be 10-50 times lower than observed in GRS 1915+\\05. The so-called rho class "heartbeats" occur as fast as every few seconds and as slow as approx 100 s, tracing a loop in the hardness-intensity diagram which resembles that previously seen in GRS 1915+\\05. However, while GRS 1915+105 traverses this loop clockwise, IGR Jl7091-3624 does so in the opposite sense. We briefly discuss our findings in the context of the models proposed for GRS 1915+105 and find that either all models requiring near Eddington luminosities for GRS 1915+105-like variability fail, or IGR Il7091-3624 lies at a distance well in excess of 20 kpc, or it harbors one of the least massive black holes known( <3 solar M).

  8. The 'Golden' cLFV channels {mu} {yields} e{gamma} and {mu} {yields} eee - the high-intensity frontier

    The muon as a laboratory for studying charged lepton-flavour violation (cLFV) has proven to be one of the most sensitive areas to probe for 'New Physics', due to the muon's copious production rate and relatively long lifetime. The search at the intensity frontier with precision-type experiments is complementary to the search for new particles at the high-energy frontier of TeV colliders. Of the three 'golden' muon channels: {mu} {yields} e{gamma}, {mu} {yields} 3e and {mu} {yields} econversion, an overview of the status of the coincidence experiments MEG, together with the latest results, which constitute the most stringent limit to date on this decay and the recently initiated Mu3e experiment, will be given.

  9. Mu and delta opioid receptors oppositely regulate motor impulsivity in the signaled nose poke task.

    Full Text Available Impulsivity is a primary feature of many psychiatric disorders, most notably attention deficit hyperactivity disorder and drug addiction. Impulsivity includes a number of processes such as the inability to delay gratification, the inability to withhold a motor response, or acting before all of the relevant information is available. These processes are mediated by neural systems that include dopamine, serotonin, norepinephrine, glutamate and cannabinoids. We examine, for the first time, the role of opioid systems in impulsivity by testing whether inactivation of the mu- (Oprm1 or delta- (Oprd1 opioid receptor gene alters motor impulsivity in mice. Wild-type and knockout mice were examined on either a pure C57BL6/J (BL6 or a hybrid 50% C57Bl/6J-50% 129Sv/pas (HYB background. Mice were trained to respond for sucrose in a signaled nose poke task that provides independent measures of associative learning (responses to the reward-paired cue and motor impulsivity (premature responses. Oprm1 knockout mice displayed a remarkable decrease in motor impulsivity. This was observed on the two genetic backgrounds and did not result from impaired associative learning, as responses to the cue signaling reward did not differ across genotypes. Furthermore, mutant mice were insensitive to the effects of ethanol, which increased disinhibition and decreased conditioned responding in wild-type mice. In sharp contrast, mice lacking the Oprd1 gene were more impulsive than controls. Again, mutant animals showed no deficit in associative learning. Ethanol completely disrupted performance in these animals. Together, our results suggest that mu-opioid receptors enhance, whereas delta-opioid receptors inhibit, motor impulsivity. This reveals an unanticipated contribution of endogenous opioid receptor activity to disinhibition. In a broader context, these data suggest that alterations in mu- or delta-opioid receptor function may contribute to impulse control disorders.

    The production of a $Z$ boson in association with a $J/\\psi$ meson in proton--proton collisions probes the production mechanisms of quarkonium and heavy flavour in association with vector bosons, and allows studies of multiple parton scattering. Using $20.3\\,\\mathrm{fb^{-1}}$ of data collected with the ATLAS experiment at the LHC, in $pp$ collisions at $\\sqrt{s}= 8$ TeV, the first measurement of associated $Z\\, +\\, J/\\psi$ production is presented for both prompt and non-prompt $J/\\psi$ production, with both signatures having a significance in excess of $5\\sigma$. The inclusive production cross-sections for $Z$ boson production (in $\\mu^+\\mu^-$ or $e^+e^-$ decay modes) in association with prompt and non-prompt $J/\\psi(\\to\\mu^+\\mu^-)$ are measured relative to the inclusive production rate of $Z$ bosons in the same fiducial volume to be $(88\\pm 16\\pm 6)\\, \\times\\, 10^{-8}$ and $(157\\pm 22\\pm 10)\\, \\times\\, 10^{-8}$ respectively. Normalised differential production cross-sections are also determined as a function ...

    A measurement of $J/\\psi$ and $\\psi(2\\mathrm{S})$ production is presented. It is based on a data sample from Pb+Pb collisions at $\\sqrt{s_{\\mathrm{NN}}}$ = 5.02 TeV and $pp$ collisions at $\\sqrt{s}$ = 5.02 TeV recorded by the ATLAS detector at the LHC in 2015, corresponding to an integrated luminosity of $0.42\\mathrm{nb}^{-1}$ and $25\\mathrm{pb}^{-1}$ in Pb+Pb and $pp$, respectively. The measurements of per-event yields, nuclear modification factors, and non-prompt fractions are performed in the dimuon decay channel for $9 < p_{T}^{\\mu\\mu} < 40$ GeV in dimuon transverse momentum, and $-2.0 < y_{\\mu\\mu} < 2.0$ in rapidity. Strong suppression is found in Pb+Pb collisions for both prompt and non-prompt $J/\\psi$, as well as for prompt and non-prompt $\\psi(2\\mathrm{S})$, increasing with event centrality. The suppression of prompt $\\psi(2\\mathrm{S})$ is observed to be stronger than that of $J/\\psi$, while the suppression of non-prompt $\\psi(2\\mathrm{S})$ is equal to that of the non-prompt $J/\\psi$ withi...

    A novel monolithic fiber-optic chirped pulse amplification (CPA) system for high energy, femtosecond pulse generation is proposed and experimentally demonstrated. By employing a high gain amplifier comprising merely 20 cm of high efficiency media (HEM) gain fiber, an optimal balance of output pulse energy, optical efficiency, and B-integral is achieved. The HEM amplifier is fabricated from erbium-doped phosphate glass fiber and yields gain of 1.443 dB/cm with slope efficiency >45%. We experimentally demonstrate near diffraction-limited beam quality and near transform-limited femtosecond pulse quality at 1.55 µm wavelength. With pulse energy >100 µJ and pulse duration of 636 fs (FWHM), the peak power is estimated to be ~160 MW.

  13. Mu2e-II Injection from PIP-II

    Energy Technology Data Exchange (ETDEWEB)

    Neuffer, David [Fermilab

    2018-04-26

    We discuss injection of 800 MeV proton beam from PIP-II into the production target for Mu2e-II, assuming a targeting and μ production scenario similar to mu2e. The incoming beam trajectory must be modified from the mu2e parameters to match the focusing fields. Adding a vertical deflection at injection enables the injected beam to reach the target. Other differences from the mu2e system must be considered, including changes in the target structure, the radiation shielding and beam dump/absorber. H- beam should be stripped to p+. Other variations are discussed.

  14. Temporal Airy pulses control cell poration

    S. Courvoisier

    2016-07-01

    Full Text Available We show that spectral phase shaping of fs-laser pulses can be used to optimize laser-cell membrane interactions in water environment. The energy and peak intensity thresholds required for cell poration with single pulse in the nJ range can be significantly reduced (25% reduction in energy and 88% reduction in peak intensity by using temporal Airy pulses, controlled by positive third order dispersion, as compared to bandwidth limited pulses. Temporal Airy pulses are also effective to control the morphology of the induced pores, with prospective applications from cellular to tissue opto-surgery and transfection.

    The study of p+Au collisions at 30 GeV laboratory beam energy is considered as a part of the CBM research program and will be performed in the first phase of FAIR with a start version of the CBM detector at SIS-100. Results of J/ψ reconstruction feasibility studies in di-muon channel in proton-nuclear collisions at SIS 100 energies are presented. The simulated detector concept includes STS and MuCh detectors. The study was performed for a wide range of MuCh detector inefficiency. Also the influence of MuCh stations misalignment on the charmonium reconstruction efficiency was studied. The algorithm allows to reconstruct J/ψ with an efficiency of 31.3 % and the signal to the background ratio of 24.4.

    Radio pulsar PSR J1028-5819 was recently discovered in a high-frequency search (at 3.1 GHz) in the error circle of the Energetic Gamma-Ray Experiment Telescope (EGRET) source 3EG J1027-5817. The spin-down power of this young pulsar is great enough to make it very likely the counterpart for the EGRET source. We report here the discovery of {gamma}-ray pulsations from PSR J1028-5819 in early observations by the Large Area Telescope (LAT) on the Fermi Gamma-Ray Space Telescope. The {gamma}-ray light curve shows two sharp peaks having phase separation of 0.460 {+-} 0.004, trailing the very narrow radio pulse by 0.200 {+-} 0.003 in phase, very similar to that of other known {gamma}-ray pulsars. The measured {gamma}-ray flux gives an efficiency for the pulsar of {approx}10-20% (for outer magnetosphere beam models). No evidence of a surrounding pulsar wind nebula is seen in the current Fermi data but limits on associated emission are weak because the source lies in a crowded region with high background emission. However, the improved angular resolution afforded by the LAT enables the disentanglement of the previous COS-B and EGRET source detections into at least two distinct sources, one of which is now identified as PSR J1028-5819.

    In order to find electron sources with low thermal emittance, cathodes based on single tip field emitter are investigated. Maximum peak current, measured from single tip in ZrC with a typical apex radius around 1 {mu}m, are presented. Voltage pulses of 2 ns duration and up to 50 kV amplitude lead to field emission current up to 470 mA from one ZrC tip. Combination of high applied electric field with laser illumination gives the possibility to modulate the emission with laser pulses. Nanoseconds current pulses have been emitted with laser pulses at 1064 nm illuminating a ZrC tip under high-DC electric field. The dependence of photo-field emitted current with the applied voltage can be explained by the Schottky effect.

    In 0.26 ..mu..m wavelength laser experiments that were performed in planar geometry with irradiances between 10/sup 13/ and 10/sup 15/ W/cm/sup 2/, the ablation pressure and the target velocity have been measured using a shock-velocity measurement and the double foil technique, respectively. The conditions are discussed that must be satisfied if the double-foil technique is to give an accurate measurement of the velocity of the dense part of the target. The rocket model has also been improved using a time-dependent applied pressure pulse, in order to accurately describe the relation between ablation pressure, target velocity, and ablated fraction. Pressures up to 50 Mbar have been easily generated since lateral energy transport is rather low with a 0.26 ..mu..m wavelength laser.

    Full text: J-PARC is an interdisciplinary facility with high power proton accelerator complex containing particle physics, nuclear physics, muon science and neutron science facilities. After 8 years construction, she is almost ready to open for users. Materials-Life Science Facility (MLF) of J-PARC is composed from very intensive pulsed neutron and muon facilities at 1 MW of the accelerated proton power. The neutron peak flux will be as high as several hundred times of existing high flux reactors. Therefore, it is highly expected that new sciences will be explored by J-PARC, MLF. The first neutrons was already produced in the last May. The MLF facility has 23 neutron beam ports. About 12 instruments are under commissioning or construction. Out of four instruments are already opened for users since December, 2008.. In the commissioning High Resolution Powder Diffractometer showed the world highest resolution d/d=0.04% as was designed. Other instruments, high intensity powder diffractometer, protein crystal diffractometer, residual stress analysis diffractometer, high intensity chopper spectrometer, confirmed expected intensity and spectrum from neutron beam line. By the end of March, a cold neutron chopper spectrometer will also come on line. Those instruments are taking advantages with optical devices for neutron transport to realize very high flux at sample position. By taking high performances of neutron moderators of MLF, the instruments will realize the world class resolution and high intensity. Ranging from Bio-science, material science, engineering, industrial use of neutrons to fundamental physics, we are exciting to see cutting-edge sciences with great anticipation to be produced from J-PARC, MLF.

    A 50 mm diameter digital DC/pulse neutron generator was developed with 25 mm ceramic drive-in target neutron tube. It was applied in the subcritical reactor test of China Institute of Atomic Energy (CIAE). The generator can produce neutron in three modes: DC, pulse and multiple pulse. The maximum neutron yield of the generator is 1 Multiplication-Sign 10{sup 8} n/s, while the maximum pulse frequency is 10 kHz, and the minimum pulse width is 10 {mu}s. As a remote controlled generator, it is small in volume, easy to be connected and controlled. The tested results indicate that penning ion source has the feature of delay time in glow discharge, and it is easier for glow discharge to happen when switching the DC voltage of penning ion source into pulse. According to these two characteristics, the generator has been modified. This improved generator can be used in many other areas including Prompt Gamma Neutron Activation Analysis (PGNAA), neutron testing and experiment.

This supply feeds a coaxial discharge reactor of the simple dielectric barrier type. The adequate operation of the system has been tested with the elimination of E. coli at 10{sup 4} and 10{sup 6} bacteria/ml concentrations, leading to reductions up to 85.3% and 95.1%, respectively, during the first 30 min of treatment.

    A study of the decay $D^{0}\\rightarrow K^{-}\\pi^{+}\\mu^{+}\\mu^{-}$ is performed using data collected by the LHCb detector in proton-proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 2.0 fb$^{-1}$. Decay candidates with muon pairs that have an invariant mass in the range 675--875 MeV$/c^2$ are considered. This region is dominated by the $\\rho^{0}$ and $\\omega$ resonances. The branching fraction in this range is measured to be ${\\cal B}$($D^{0}\\rightarrow K^{-}\\pi^{+}\\mu^{+}\\mu^{-}$ ) = $( 4.17 \\pm 0.12(stat) \\pm 0.40(syst) )\\times10^{-6}$. This is the first observation of the decay $D^{0}\\rightarrow K^{-}\\pi^{+}\\mu^{+}\\mu^{-}$. Its branching fraction is consistent with the value expected in the Standard Model.

    A search for the lepton-flavour violating decays $B^0_s \\rightarrow e^{\\pm}\\mu^{\\mp}$ and $B^0 \\rightarrow e^{\\pm} \\mu^{\\mp}$ is performed with a data sample, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of $pp$ collisions at $\\sqrt{s} = 7$, TeV, collected by the LHCb experiment. The observed number of $B^0_s \\to e^{\\pm} \\mu^{\\mp}$ and $B^0 \\to e^{\\pm} \\mu^{\\mp}$ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be $BR(B^0_s \\to e^{\\pm} \\mu^{\\mp} 107$ TeV/c$^2$ and $M_{\\rm LQ} (B^0 \\to e^{\\pm} \\mu^{\\mp}) > 126$ TeV/c$^2$ at 95% C.L., and are a factor of two higher than the previous bounds.

  6. SU-F-J-112: Clinical Feasibility Test of An RF Pulse-Based MRI Method for the Quantitative Fat-Water Segmentation

    Purpose: Quantitative fat-water segmentation is important not only because of the clinical utility of fat-suppressed MRI images in better detecting lesions of clinical significance (in the midst of bright fat signal) but also because of the possible physical need, in which CT-like images based on the materials’ photon attenuation properties may have to be generated from MR images; particularly, as in the case of MR-only radiation oncology environment to obtain radiation dose calculation or as in the case of hybrid PET/MR modality to obtain attenuation correction map for the quantitative PET reconstruction. The majority of such fat-water quantitative segmentations have been performed by utilizing the Dixon’s method and its variations, which have to enforce the proper settings (often predefined) of echo time (TE) in the pulse sequences. Therefore, such methods have been unable to be directly combined with those ultrashort TE (UTE) sequences that, taking the advantage of very low TE values (∼ 10’s microsecond), might be beneficial to directly detect bones. Recently, an RF pulse-based method (http://dx.doi.org/10.1016/j.mri.2015.11.006), termed as PROD pulse method, was introduced as a method of quantitative fat-water segmentation that does not have to depend on predefined TE settings. Here, the clinical feasibility of this method is verified in brain tumor patients by combining the PROD pulse with several sequences. Methods: In a clinical 3T MRI, the PROD pulse was combined with turbo spin echo (e.g. TR=1500, TE=16 or 60, ETL=15) or turbo field echo (e.g. TR=5.6, TE=2.8, ETL=12) sequences without specifying TE values. Results: The fat-water segmentation was possible without having to set specific TE values. Conclusion: The PROD pulse method is clinically feasible. Although not yet combined with UTE sequences in our laboratory, the method is potentially compatible with UTE sequences, and thus, might be useful to directly segment fat, water, bone and air.

    We experimentally demonstrate that plasma waveguides produced with ultra-short laser pulses (sub-picosecond) in gas jets are capable of guiding high intensity laser pulses. This scheme has the unique ability of guiding a high-intensity laser pulse in a plasma waveguide created by the same laser system in the very simple and stable experimental setup. A hot plasma column was created by a femtosecond class laser that expands into an on-axis parabolic low density profile suitable to act as a wav...

    The pulsed current cathodic protection (PCCP) is a new cathodic protection (CP) technology and shows more advantages over the conventional DC cathodic protection (DCCP) in oil well casing system. However, little information about PCCP is reported. In this research, a simulated CP system was set up in a pool of 3.5 m x 2.0 m x 3.0 m size, in which the effects of the square wave pulsed current (SWPC) parameters (amplitude: IA, frequency: f, duty cycle: P), auxiliary anode distance (d) and media conductivity ({mu}) on the cathodic potential (E) distribution were studied, and the protection effects of PCCP and DCCP were compared. The results show that with increase of the square wave parameters (IA, f, P), the E distribution becomes more negative and the effects of each current parameter are relate closely to the cathode polarizing state. Only with suitable square wave parameters can the whole cathode be effectively protected. With increase of d and {mu}, the E distribution becomes more uniform. Compared with DCCP system, PCCP system has much more uniform E distribution, costs less average current, and gains much better protection effects. Further, the mechanism of PCCP was analyzed.

  10. High-energy few-cycle pulse compression through self-channeling in gases

    Complete test of publication follows. Nonlinear spectral broadening of femtosecond optical pulses by intense propagation in a Kerr medium followed by temporal compression constitutes the Holy Grail for ultrafast science since it allows the generation of intense few-cycle optical transients from longer pulses provided by now commercially available femtosecond lasers. Tremendous progress in high-field and attosecond physics achieved in recent years has triggered the need for efficient pulse compression schemes producing few-cycle pulses beyond the mJ level. We studied a novel pulse compression scheme based on self-channeling in gases, which promises to overcome the energy constraints of hollow-core fiber compression techniques. Fundamentally, self-channeling at high laser powers in gases occurs when the self-focusing effect in the gas is balanced through the dispersion induced by the inhomogeneous refractive index resulting from optically-induced ionization. The high nonlinearity of the ionization process poses great technical challenges when trying to scale this pulse compression scheme to higher energies input energies. Light channels are known to be unstable under small fluctuations of the trapped field that can lead to temporal and spatial beam breakup, usually resulting in the generation of spectrally broad but uncompressible pulses. Here we present experimental results on high-energy pulse compression of self-channeled 40-fs pulses in pressure-gas cells. In the first experiment, performed at the Lund Laser Center in Sweden, we identified a particular self-channeling regime at lower pulse energies (0.8 mJ), in which the ultrashort pulses are generated with negative group delay dispersion (GDD) such that they can be readily compressed down to near 10-fs through simple material dispersion. Pulse compression is efficient (70%) and exhibits exceptional spatial and temporal beam stability. In a second experiment, performed at the LOA-Palaiseau in France, we

    In LIU-30 power linear pulsed induction electron accelerator (40 MeV, 10 kA, 25 ns) 288 radial lines with water insulation serve as energy accumulators and shapers of accelerating voltage pulses. The lines are charged simultaneously up to 500 kV using a system comprising 72 Arkadiev-Marx screened generators. To control parameter of synchronous pulses of charging current with up to 60 kA amplitude and 0.85 mu s duration in every of 72 charging circuits one applies a computer-aided system. Current pulse is recorded at output of every generator using the Rogowski coil signal from which via a cable line is transmitted to an analog-digital converter, is processed with 50 ns sampling and is recorded to a memory unit. Upon actuation of accelerator the signals are sequentially or selectively displayed and are compared with pulse typical shape

    The experiment objective is to analyze temperature variation, by means of three different application techniques of Nd:YAG laser in the root canals of singlerooted anterior teeth. Three root canals were instrumented, irrigated, X-rayed to measure the remaining dentin in the apical area and submitted to laser irradiation techniques used by Gutknecht, Matsumoto and a new technique with oscillatory movement. The used laser parameters were: pulse energy 250 mJ, frequency 5 Hz, pulse fluency 354 J/cm{sup 2}, average potency 1,25 W, pulse width 300 {mu}s, fiber core diameter 300 {mu}s and interval of thermal relaxation of 20 s. After temperature evaluation and interpretation of the obtained data, it was concluded: 1) the oscillatory technique provided a better heat distribution during the laser application, when analyzing the graphs separately; 2) all the used techniques are within a pattern of safety, analyzing the average and highest temperatures of the apical area and the middle third, even so, disrespecting the last application day and the middle third of root 'C'.(author)

    MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI were more resistant to Cd than wild-type cells transfected with vector alone. MuSI transgenic plants were also more resistant to Cd. MuSI transgenic tobacco plants absorbed less Cd than wild-type plants. Cd translocation from roots to shoots was reduced in the transgenic plants, thereby avoiding Cd toxicity. The number of short trichomes in the leaves of wild-type tobacco plants was increased by Cd treatment, while this was unchanged in MuSI transgenic tobacco. These results suggest that MuSI transgenic tobacco plants have enhanced tolerance to Cd via reduced Cd uptake and/or increased Cd immobilization in the roots, resulting in less Cd translocation to the shoots.

    Highly active coronas with a peak power of up to 25 MW p/m corona wire and kJ/liter energy densities in the streamer channels can be produced by pulsed power. Since the voltage pulses are short, full breakdown does not occur even though the discharge currents are hundreds of Amperes. A matched pulsed power source can deposit up to 80% of its electrical energy into such a controlled discharge. Reliable and efficient sources characterized by 100 kV,150 ns wide pulses at 1000 Hz have passed 400 hours of operation. The area of applications is growing: VOC control, hot gas cleanup, water and air purification and sterilization. (author)

    Using a magnetic bunch compression method, a 26.5 MeV subpicosecond electron single bunch was generated with the L-band linac of Osaka University. The coherent transition radiation emitted from the subpicosecond single bunch was observed at wavelengths from 100 to 700 {mu}m. The intensity was 7.9x10{sup 9} times higher than that of the incoherent transition radiation obtained by calculation. The length of the compressed electron bunch was evaluated to be roughly 50 fs (rms) from the analysis of the spectra of the transition radiation. The coherent transition radiation has high enough intensity to be applied to pulse radiolysis as a pulsed light source.

Study aims were to evaluate: (i DC activation/maturation milieu (TNF-α +/- IFN-α and its effects on CD8+ hTERT-specific T cell responses to class I epitopes (p540 or p865, (ii CD8+ hTERT-specific T cell responses elicited by vaccination with class I alone or both class I and II epitope (p766 and p672-pulsed DCs, prepared without IFN-α, (iii association between circulating T regulatory cells (Tregs and clinical responses. Methods Autologous DCs were generated from 10 patients (HLA-0201 with advanced cancer by culturing CD14+ blood monocytes in the presence of GM-CSF and IL-4 supplemented with TNF-α [DCT] or TNF-α and IFN-α [DCTI]. The capacity of the DCs to induce functional CD8+ T cell responses to hTERT HLA-0201 restricted nonapeptides was assessed by MHC tetramer binding and peptide-specific cytotoxicity. Each DC preparation (DCT or DCTI was pulsed with only one type of hTERT peptide (p540 or p865 and both preparations were injected into separate lymph node draining regions every 2–3 weeks. This vaccination design enabled comparison of efficacy between DCT and DCTI in generating hTERT peptide specific CD8+ T cells and comparison of class I hTERT peptide (p540 or p865-loaded DCT with or without class II cognate help (p766 and p672 in 6 patients. T regulatory cells were evaluated in 8 patients. Results (i DCTIs and DCTs, pulsed with hTERT peptides, were comparable (p = 0.45, t-test in inducing peptide-specific CD8+ T cell responses. (ii Class II cognate help, significantly enhanced (p (iii Clinical responders had significantly lower (p Conclusion Addition of IFN-α to ex vivo monocyte-derived DCs, did not significantly enhance peptide-specific T cell responses in vivo, compared with TNF-α alone. Class II cognate help significantly augments peptide-specific T cell responses. Clinically favourable responses were seen in patients

    The formation of regular Trichel pulses in electronegative gaseous mixtures is studied experimentally, with emphasis on the consequences of different electron attachment mechanisms in the used gas mixtures on the behavior of the discharge. Negative ions are believed to be responsible for excitation of the Trichel pulses. The experimental data presented in the paper give evidence that the origin of the negative ions does not play any substantial role in the formation of the initial part of the Trichel pulses. (J.U.)

    This article proposes a technical solution for using a CO laser facility for the industrial separation of uranium used in the production of fuel for nuclear power plants, employing a method of laser isotope separation of uranium with condensation repression in a free jet. The laser operation with nanosecond pulse irradiation can provide an acceptable efficiency in the separating unit and a high efficiency of the laser with the wavelength of 5.3 {mu}m. In the present work we also introduce a calculation model and define the parameters of a mode-locked CO laser with a RF discharge in the supersonic stream. The average pulsed CO laser power of 3 kW is sufficient for efficient industrial isotope separation of uranium in one stage.

    We describe the pulse generation, shaping, and preamplification system for the nanosecond beamlines of the Orion laser facility. The system generates shaped laser pulses of up to approximately 1 J of 100 ps-5 ns duration with a programmable temporal profile. The laser has a 30th-power supergaussian spatial profile and is diffraction limited. The system is capable of imposing 2D smoothing by spectral dispersion upon the beam, which will produce a nonuniformity of 10% rms at the target.

    In cold pulse experiments in J-TEXT, not only are rapid electron temperature increases in the core observed, but also steep rises in the inner density are found. Moreover, some evidence of acceleration of the core toroidal rotation is also observed during the non-local transport process of electron temperature. These new findings of cold pulse experiments in J-TEXT suggest that turbulence spreading is a possible mechanism for the non-local transport dynamics.

    Ultrashort pulse lasers are an important tool in scientific and industrial applications. However, many applications are demanding higher average powers from these ultrashort pulse sources. This can be achieved by combining direct diode pumping with novel gain media designs. In particular, ultrashort pulse fiber lasers are now delivering average powers in the kW range. However, the design of fiber lasers, producing pulses with high peak-powers, is challenging due to the impact of nonlinear effects. To significantly reduce these detrimental effects in ultrashort pulse fiber amplifers, the combination of chirped pulse amplification (CPA) and large mode area fibers is employed. Using these methods, the pulse energy of fiber lasers has been steadily increasing for the past few years. Recently, a fiber-based CPA-system has been demonstrated which produces pulse energies of around 1 mJ. However, both the stretching and the enlargement of the mode area are limited, and therefore, the impact of nonlinearity is still noticed in systems employing such devices. The aim of this thesis is the analysis of CPA-systems operated beyond the conventional nonlinear limit, which corresponds to accumulated nonlinear phase-shifts around 1 rad. This includes a detailed discussion of the influence of the nonlinear effect self-phase modulation on the output pulse of CPA-systems. An analytical model is presented. Emphasis is placed on the design of novel concepts to control the impact of self-phase modulation. Pulse-shaping is regarded as a powerful tool to accomplish this goal. Novel methods to control the impact of SPM are experimentally demonstrated. The design of these concepts is based on the theoretical findings. Both amplitude- and phase-shaping are studied. Model-based phase-shaping is implemented in a state-of-the-art fiber CPA-system. The influence of the polarization state is also highlighted. Additionally, existing techniques and recent advances are put into context. (orig.)

  8. LHCb - Measurement of the branching fraction ratio $\\cal{B}$ $(B_{c}^{+} \\to \\psi(2S)\\pi^+)$ / $\\cal{B}$ $(B_{c}^{+} \\to {J}\\psi\\pi^+)$ at LHCb

    Using the $pp$ collision data collected by LHCb at center-of-mass energies $\\sqrt{s} \\, = 7 \\, {\\rm TeV} \\,$ and $8 \\, {\\rm TeV} \\,$, corresponding to an integrated luminosity of $3 \\, \\mathrm{fb}^{-1} \\,$, the ratio of the branching fraction of the $B_{c}^{+} \\to \\psi(2S)\\pi^+$ decay relative to that of the $B_{c}^{+} \\to J/\\psi\\pi^+$ decay is measured to be ${0.268 \\pm 0.032\\mathrm{\\,(stat)} \\pm 0.007\\mathrm{\\,(syst)} \\pm 0.006\\,(\\mathrm{BF}) }$. The first uncertainty is statistical, the second is systematic, and the third is due to the uncertainties on the branching fractions of the $J/\\psi \\to \\mu^{+}\\mu^{-}$ and $\\psi(2S) \\to \\mu^{+}\\mu^{-}$ decays. To enhance the signal significance with limited $B_{c}^{+}$ statistics, the boosted decision tree selection is used to separate the signal and background effectively. The systematic uncertainties are discussed extensively. This measurement is consistent with the previous LHCb result, and the statistical uncertainty is halved.

  9. Energy scaling of the "heartbeat" pulse width of GRS 1915+105, IGR J17091-3624, and MXB 1730-335 from Rossi-XTE observations

    We investigate some key aspects of the "heartbeat" variability consisting of series of bursts with a slow rise and a fast decay, thus far detected only in GRS 1915+105, IGR J17091-3624, and MXB 1730-335. A previous analysis based on BeppoSAX data of GRS 1915+105 revealed a hard-X delay (HXD), that is a lag of the burst rise at higher energies with respect to lower ones; this leads to narrower pulse widths, w, at higher energies. We here use some light curves of Rossi-XTE observations of GRS 1915+105 for a deeper analysis of this effect and search for its presence in those extracted from some IGR J17091-3624 and MXB 1730-335 observations performed with the same satellite. Our results show that, at variance with GRS 1915+105, no HXD is evident in the light curves of MXB 1730-335 and only a marginal HXD may be argued for IGR J17091-3624. For GRS 1915+105 we find a decreasing trend of the pulse width with energy following a power law w = A ṡ E-s with an index s ≈ 0.8. Furthermore, we confirm the increase of the HXD with the recurrence time Trec of the bursts in each series that was already found in previous works using BeppoSAX data. Based on a spectral analysis of these three sources we conclude that the differences highlighted in the properties of the "heartbeat" variability are probably related to the different accreting compact object and the eventual presence of a corona in these binary interacting systems.

    We report a core pumped thulium-doped fiber amplifier that generates 1.4 μJ pulses at 1980 nm with a repetition rate of 3.6 MHz preserving the original spectral bandwidth of the oscillator. The amplifier chain is seeded by a passively modelocked fiber laser with 5 mW output power and the pulses are stretched to 800 picoseconds. The amplifier is core pumped by a single mode erbium fiber laser. The slope efficiency is 35%. To the best of our knowledge, this is the first demonstration of sub nanosecond pulses with energies higher than 1 μJ coming out of a thulium-doped fiber amplifier.

    We demonstrate self-compression of deep-ultraviolet (DUV) pulses by filamentation in krypton. In contrast to self-compression in the near-infrared, that in the DUV is associated with a red-shifted sub-pulse appearing in the pulse temporal profile. The achieved pulse width of 15 fs is the shortest among demonstrated sub-mJ deep-ultraviolet pulses.

    Almahata Sitta meteorites are unique polymict breccia, comprising of many different meteorite groups as individual fragments dominated by ureilite lithologies and are considered to be recovered fragments of the asteroid 2008TC3. Recently, two unusual Almahata Sitta samples (MS-MU-011 and MS-MU-012) have been reported that show close petrogenetic relationships to ureilites. MS-MU-011 is a trachyandesite mainly composed of feldspar (plagioclase and anorthoclase) and pyroxene (pigeonite and augite) having ureilitic oxygen isotopic ratios. MS-MU-012 is the first ureilite example (unbrecciated) containing primary plagioclase crystals. The findings of these two rock types are important to better understand formation conditions of ureilites and the evolution of their parent body(s). In this abstract we discuss formation conditions of these ureilite-related rocks using redox state estimate by Fe valence states of plagioclase and olivine cooling rate calculations.

    1975-01-01

    Pulsed HF chemical laser oscillator energies were scaled from millijoules to several kilojoules over the period 1970-1974, reaching approximately 10 J with SF 6 and transverse discharges, and using electron-beam initiation and elemental F 2 above 1000J. This demonstrated scalability to large energy with acceptable electrical efficiency is only one prerequisite for application of this gas laser in fusion; equally important matters are achievement of focusable, approximately 1 ns pulses, couplable to light-element targets, all from an affordable system. Exploratory MOPA experiments are reported which address control of HF laser beam focusability and pulse duration, using SF 6 -based experimental oscillator--amplifier sequences and Pockels' cell switching. Simultaneous multiline lasing with 2.6 less than or equal to lambda less than or equal to 3.1 μm and high specific gain and energy density are particularly important factors encountered with HF, where amplifier pumping and lasing occur in a substantially cw temporal relationship, even in less than 100 ns bursts. Time-resolved SF 6 --HI oscillator spectra contain 27 simultaneous lines from six vibrational bands. An apertured, SF 6 -hydrocarbon pin-discharge oscillator generates approximately 10 mJ of TEM 00 radiation, which is amplified to approximately 1 J in approximately 150 ns by a TEA amplifier and p []opagated tens of meters. A three-stage system coupling these elements through an approximately 1 ns electrooptic gate to a greater than 10 J, e-beam energized amplifier is under development. (auth)

    1978-01-01

    In studies with bg/sup J//bg/sup J/:W/W/sup v/ chimeric mice, we used the beige neutrophil marker as a criterion of W/W/sup v/ marrow replacement by implanted bg/sup J//bg/sup J/ stem cells. Data from a 50-fold range of inoculum doses and a 2 y period of observation indicate a hyperbolic pattern of replacement expressed as a log dose-response relationship. The saturating effect with increasing inoculum dose was interpreted as reflecting random initial stem cell seeding in bone marrow coupled with a decreasing efficiency of colonization by migration. From the statistics of random sampling and the exponential decrease of the 63% replacement dose with time, we estimate that W/W/sup v/ marrow contains about 2600 stem cell regulatory volumes of about 10/sup 8/ ..mu../sup 3/ (50 cell diameters) each, a dimension consistent with concepts of short-range cell-cell interactions. Our observations suggest that each regulatory volume is essentially self-contained and that stem cell migration is generally restricted to contiguous volumes.

    In this study the authors used semi-quantitative in vitro autoradiography to compare the levels of binding to central mu 1 , mu 2 , and delta opioid sites in two strains of mice, C57BL/6BY and CXBK. The CXBK strain is known to be deficient in whole brain opioid binding sites and to be less sensitive than the C57 strain to the analgesic and locomotor stimulatory effects of opiates and opioids. Delta sites were visualized using [ 3 H][D-Ala 2 -D-Leu 5 ]-enkephalin (DADL) plus a low concentration of morphine, total mu sites (mu 1 and mu 2 ) were visualized using [ 3 H]dihydromorphine (DHM), and mu 2 sites were visualized using [ 3 H]DHM plus a low concentration of DADL. Binding to mu 1 sites was determined by subtracting mu 2 binding from total mu binding. The authors found that the two strains did not consistently differ in the levels of delta sites. The CXBK strain, however, either had less or the same amount of mu binding as the C57 strain in all areas studied. The CXBK strain was especially deficient in mu 1 binding, particularly in areas involved in pain processing. (Auth.)

    2017-12-01

    We propose and demonstrate a simple route to few-optical-cycle pulse generation from a mid-infrared fiber laser through nonlinear compression of pulses from a holmium-doped fiber oscillator using a short length of chalcogenide fiber and a grating pair. Pulses from the oscillator with 265-fs duration at 2.86 {\\mu}m are spectrally broadened through self-phase modulation in step-index As2S3 fiber to 141-nm bandwidth and then re-compressed to 70 fs (7.3 optical cycles). These are the shortest pulses from a mid-infrared fiber system to date, and we note that our system is compact, robust, and uses only commercially available components. The scalability of this approach is also discussed, supported by numerical modeling.

    The long pulse operation of the PV3030 klystron for FEL linac at LEBRA in Nihon University has been improved considerably by the additional vacuum system placed immediately downstream the klystron output rf window. With the new vacuum system, the large conductance has enabled a high vacuum in normal operation and a quick recovery when the dielectric breakdown occurred. A high vacuum near the rf window may be essentially important for a stable operation of the high power klystron with long pulse duration. Now the PV3030 klystron can be operated at the condition of 20 MW x 20 {mu}s x 12.5 Hz. (author)

    The accreting millisecond X-ray pulsar SAX J1808.4−3658 shows a peculiar orbital evolution that proceeds at a very fast pace. It is important to identify the underlying mechanism responsible for this behavior because it can help to understand how this system evolves and which physical processes (such as mass loss or spin–orbit coupling) are occurring in the binary. It has also been suggested that, when in quiescence, SAX J1808.4−3658 turns on as a radio pulsar, a circumstance that might provide a link between accreting millisecond pulsars and black-widow (BW) radio pulsars. In this work, we report the results of a deep radio pulsation search at 2 GHz using the Green Bank Telescope in 2014 August and an X-ray study of the 2015 outburst with Chandra , Swift XRT, and INTEGRAL . In quiescence, we detect no radio pulsations and place the strongest limit to date on the pulsed radio flux density of any accreting millisecond pulsar. We also find that the orbit of SAX J1808.4−3658 continues evolving at a fast pace. We compare the orbital evolution of SAX J1808.4−3658 to that of several other accreting and nonaccreting binaries, including BWs, redbacks, cataclysmic variables, black holes, and neutron stars in low-mass X-ray binaries. We discuss two possible scenarios: either the neutron star has a large moment of inertia and is ablating the donor, generating mass loss with an efficiency of 40%, or the donor star has a strong magnetic field of at least 1 kG and is undergoing quasi-cyclic variations due to spin–orbit coupling.

    An ion beam pulse radiolysis system has been constructed at HIMAC facility. Ion beam of 24MeV He{sup 2+} with the duration longer than 1 {mu}s is available for irradiation. Three kinds of aqueous solutions, (C{sub 6}H{sub 5}){sub 2}CO, NaHCO{sub 3}, and KSCN, were irradiated and the absorption signals corresponding to (C{sub 6}H{sub 5}){sub 2}CO{sup -}, CO{sub 3}{sup -}, and (SCN){sub 2}{sup -} respectively were observed. Ghost signals which interfere with the measurement are also discussed. (author)

    The interaction of lasers with the hard structures of the teeth, has found the excess of heat as a problem for its utilization. This study analyzes, in vitro, the interaction of the ultrashort pulse laser of Ti:safire (830 nm) with the bovine dental enamel. The system consisted in one main oscillator integrated with an amplifier (CPA). The pulses extracted before the temporal compression inside the amplifier had 30 ps, 1000 Hz and ∼1 mJ. The pulses extracted after the compression had 60 fs, 1000 Hz and ∼0,7 mJ. The M 2 was 1,3, the focal lens 2,5 cm, the focal distance 29,7 and a computerized translation stage x,y,z. We evaluated the amount of tissue removed per pulse,the resulting cavities and the surrounding tissues not irradiated, under OM and SEM. The fluency was the major factor for differentiating the two regimens studied, therefore, the intensity was not so important as we expected in this process. We found: one ablation region in 'cat tongue', one ablation length, one fluency ∼0,7 J/cm 2 for 30 ps and ∼0,5 J/cm 2 for 60 fs (50% of high speed burr), smooth edge for 30 ps and high precision of the sharp edge cut of submicrometric order for 60 fs.

  6. Multi-band morpho-Spectral Component Analysis Deblending Tool (MuSCADeT): Deblending colourful objects

    Science.gov (United States)

    Joseph, R.; Courbin, F.; Starck, J.-L.

    2016-05-01

    We introduce a new algorithm for colour separation and deblending of multi-band astronomical images called MuSCADeT which is based on Morpho-spectral Component Analysis of multi-band images. The MuSCADeT algorithm takes advantage of the sparsity of astronomical objects in morphological dictionaries such as wavelets and their differences in spectral energy distribution (SED) across multi-band observations. This allows us to devise a model independent and automated approach to separate objects with different colours. We show with simulations that we are able to separate highly blended objects and that our algorithm is robust against SED variations of objects across the field of view. To confront our algorithm with real data, we use HST images of the strong lensing galaxy cluster MACS J1149+2223 and we show that MuSCADeT performs better than traditional profile-fitting techniques in deblending the foreground lensing galaxies from background lensed galaxies. Although the main driver for our work is the deblending of strong gravitational lenses, our method is fit to be used for any purpose related to deblending of objects in astronomical images. An example of such an application is the separation of the red and blue stellar populations of a spiral galaxy in the galaxy cluster Abell 2744. We provide a python package along with all simulations and routines used in this paper to contribute to reproducible research efforts. Codes can be found at http://lastro.epfl.ch/page-126973.html

    Radiofrequency glow discharge coupled to optical emission spectroscopy has been used in pulsed mode in order to perform a detailed study of the measured temporal emission profiles for a wide range of copper transitions. Special attention has been paid to the early emission peak (or so-called pre-peak), observed at the beginning of the emission pulse profile. The effects of the important pulse parameters such as frequency, duty cycle, pulse width and power-off time, have been studied upon the Cu pulse emission profiles. The influence of discharge parameters, such as pressure and power, was studied as well. Results have shown that the intensity observed in the pre-peak can be 10 times as large as the plateau value for resonant lines and up to 5 times in case of transitions to the metastable levels. Increasing pressure or power increased the pre-peak intensity while its appearance in time changed. The pre-peak decreased when the discharge off-time was shorter than 100 {mu}s. According to such results, the presence of the pre-peak could be probably due to the lack of self-absorption during the first 50 {mu}s, and not to the ignition of the plasma. Under the selected operation conditions, the use of the pre-peak emission as analytical signals increases the linearity of calibration curves for resonant lines subjected to self-absorption at high concentrations.

  10. Arbitrarily accurate twin composite π -pulse sequences

    Torosov, Boyan T.; Vitanov, Nikolay V.

    2018-04-01

    We present three classes of symmetric broadband composite pulse sequences. The composite phases are given by analytic formulas (rational fractions of π ) valid for any number of constituent pulses. The transition probability is expressed by simple analytic formulas and the order of pulse area error compensation grows linearly with the number of pulses. Therefore, any desired compensation order can be produced by an appropriate composite sequence; in this sense, they are arbitrarily accurate. These composite pulses perform equally well as or better than previously published ones. Moreover, the current sequences are more flexible as they allow total pulse areas of arbitrary integer multiples of π .

    Multicycle THz pulse generation by optical rectification in GaP semiconductor nonlinear material is investigated by numerical simulations. It is shown that GaP can be an efficient and versatile source with up to about 8% conversion efficiency and a tuning range from 0.1 THz to about 7 THz. Contact-grating technology for pulse-front tilt can ensure an excellent focusability and scaling the THz pulse energy beyond 1 mJ. Shapeable infrared pump pulses with a constant intensity-modulation period can be delivered for example by a flexible and efficient dual-chirped optical parametric amplifier. Potential applications include linear and nonlinear THz spectroscopy and THz-driven acceleration of electrons.

    Our experiments focused on the examination of the distribution of mu opioid receptor binding sites in normal human brain using the highly selective ligand [ 3 H]DAGO, in both membrane binding assay and in vitro receptor autoradiography. Mu opioid binding sites are very discretely distributed in human brain with high densities of sites found in the posterior amygdala, caudate, putamen, hypothalamus and certain cortical areas. Moreover the autoradiographic distribution of [ 3 H]DAGO binding sites clearly reveals the discrete lamination (layers I and III-IV) of mu sites in cortical areas

    Full Text Available We present a comparison of two alternative laser layouts for HiLASE and ELI Beamlines projects. The cryogenically cooled laser is 100 J class with 2 ns pulse length and operates at 10 Hz repetition rate. The laser beam is intended for industrial applications in HiLASE, for OPCPA pumping in ELI Beamlines and can serve as a test bed for large scale high repetition rate fusion lasers. First layout utilizes classical scheme with preamplifier and main amplifier, while the second layout utilizes single amplifier scheme with two amplifier heads. The comparison is based on the results obtained from homemade MATLAB code for evaluation of amplified spontaneous emission and stored energy and on a beam propagation simulated in MIRÓ code.

    Full Text Available Circulating antibodies of the acetylcholine receptor (AchRAb are detectable in most patients with generalized myasthenia gravis (MG. A newly discovered antibody against muscle-specific kinase (MuSKAb has been detected in 40–70% of AchRAb-negative MG patients. We report a series of Taiwanese MuSKAb-positive patients, and compare their clinical features with MuSKAb-negative patients and also with MuSKAb-positive Caucasians. Five out of 44 seronegative generalized MG patients (11.4% were positive for MuSKAb. Patients with MuSKAb tended to have severe disability and bulbar involvement, and more often experienced crisis or impending crisis. Although all of these patients showed an initial response to immunosuppressant therapy, they had greater disability at follow-up. The clinical features of Taiwanese MuSKAb-positive patients were not different from those of Caucasians, except for a lower prevalence.

    During the 2004 Au-Au run with {radical}(S{sub NN}) = 200 GeV at RHIC, the PHENIX collaboration commissioned a trigger for J/{psi} {yields} e{sup +}e{sup -} and the high mass di-lepton continuum. The PHENIX experiment has excellent capability for identifying electrons since it includes a high resolution electromagnetic calorimeter array and ring imaging Cerenkov counters. The main features expected from photo-produced di-leptons are small net transverse momentum of the pair and low multiplicity of produced tracks (both characteristic of diffusive processes). Adequate event selection and a thorough extraction of the J/{psi} signal has led to a J/{psi} photoproduction cross-section of (48 {+-} 14 (stat) {+-} 16 (syst)) {mu}b.

    We have developed neutron spin flip choppers with high S/N ratio and high intensity for pulsed sources using multi-stage spin flip choppers. It is not easy for us to obtain a very short neutron pulse less than 10 μs using a spin flip chopper, due to the time constant L/R in the normal LR circuit. We will discuss a method obtaining a very short neutron pulse applying the modified push-pull circuit proposed by Ito and Takahashi [4] to the double spin flip chopper with polarizing guides

    High-magnetic-field pulsars represent an important class of objects for studying the relationship between magnetars and radio pulsars. Here we report on four Chandra observations of the high-magnetic-field pulsar J1718-3718 (B = 7.4 x 10 13 G) taken in 2009 as well as a reanalysis of 2002 Chandra observations of the region. We also report an improved radio position for this pulsar based on ATCA observations. We detect X-ray pulsations at the pulsar's period in the 2009 data, with a pulsed fraction of 52% ± 13% in the 0.8-2.0 keV band. We find that the X-ray pulse is aligned with the radio pulse. The data from 2002 and 2009 show consistent spectra and fluxes: a merged overall spectrum is well fit by a blackbody of temperature 186 +19 -18 eV, slightly higher than predicted by standard cooling models; however, the best-fit neutron star atmosphere model is consistent with standard cooling. We find the bolometric luminosity L ∞ bb = 4 +5 -2 x 10 32 erg s -1 ∼0.3 E-dot for a distance of 4.5 kpc. We compile measurements of the temperatures of all X-ray-detected high-B pulsars as well as those of low-B radio pulsars and find evidence for the former being hotter on average than the latter.

    A semiconductor laser (LD) excited solid state laser using an LD as an excited light source is under discussion for its practical applications to measurements, processing, communications, office automation, and medical areas. This paper describes the discussions given on the short pulse transmission using AOQ switching elements in the LD excited solid state laser with a long wave length band (1.3{mu}m), which is expected of its application in the communications and measurements area. Based on a possibility of raising a measurements resolution by making the pluses in the LD excited solid state laser, and experiments were performed using Nd:YLF as a laser host. as a results, it was found that the smaller the effective mode volume V {sub eff},the smaller the pulse width, and that the ratio of number of initial inversion distribution (N{sub i}/N{sub t}), an important parameter to determine pulse widths, can be obtained from the ratio of the LD exciting light to the input power (P{sub in}/P{sub t}). 7 refs., 14 figs., 2 tabs.

    In this study, the ablation mass features related to reflectivity of bulk Molybdenum (Mo) were investigated by a Ti: Sa 6 fs laser pulse at central wavelength 790 nm. The ablated mass removal was determined using Confocal Microscopy (CM) technique. The surface reflectivity was calibrated and measured by a Lambda 950 spectrophotometer as well as a CCD camera during laser ablation. The ablation mass loss per pulse increase with the increasing of laser shots, meanwhile the surface reflectivity decrease. The multi-pulses (100 shots) ablation threshold of Mo was determined to be 0.15 J/cm2. The incubation coefficient was estimated as 0.835. The reflectivity change of the Mo target surface following multi-pulses laser ablation were studied as a function of laser ablation shots at various laser fluences from 1.07 J/cm2 to 36.23 J/cm2. The results of measured reflectivity indicate that surface reflectivity of Mo target has a significant decline in the first 3-laser pulses at the various fluences. These results are important for developing a quantitative analysis model for laser induced ablation and laser induced breakdown spectroscopy for the first wall diagnosis of EAST tokamak.

    The analysis of the penguin decay $B_d \\to K^*\\mu\\mu$ at LHCb can act as a laboratory for the discovery and understanding of new physics. Through the Operator Product Expansion, the decay kinematics are well understood in both the Standard Model and in a large range of new physics scenarios. The theoretical errors from QCD effects can be characterized and a set of observables have been derived which minimise their influence in measurements. We will describe how these measurements can be made in LHCb with special emphasis on what can be done with a first run of the LHC with a few hundred pb$^{-1}$ of integrated luminosity.

    The origin of the Nuclear Physics Future Plan was the NUMATRON project, with which high energy heavy ions were to be accelerated. This project was not successful and another project 'Large Hadron Project' was proposed in 1986 to deliver both of high energy heavy ions and high intensity protons. This project was somewhat modified to build a 1GeV 200μA proton linac in KEK (Institute for High Energy Physics) site to produce pulsed neutrons, pulsed muons and unstable nuclei as a first step to 'Japan Hadron Project'. The linac was expected also to be an injector for KEK 12GeV synchrotron. In 2001 accelerator projects under the Ministry of Education and the Science and Technology Agency were unified to form J-PARC project, which was approved on a chance when the former two government organizations were integrated. J-PARC project aims at performing the materials and life sciences by 3GeV protons, nuclear and elementary particle physics by 50GeV protons and the researches on nuclear transmutation by 0.6GeV protons.

    We present a high peak power degenerated parametric amplifier operating at 1030 nm and 97 kHz repetition rate. Pulses of a state-of-the art fiber chirped-pulse amplification (FCPA) system with 840 fs pulse duration and 410 microJ pulse energy are used as pump and seed source for a two stage optical parametric amplifier. Additional spectral broadening of the seed signal in a photonic crystal fiber creates enough bandwidth for ultrashort pulse generation. Subsequent amplification of the broadband seed signal in two 1 mm BBO crystals results in 41 microJ output pulse energy. Compression in a SF 11 prism compressor yields 37 microJ pulses as short as 52 fs. Thus, pulse shortening of more than one order of magnitude is achieved. Further scaling in terms of average power and pulse energy seems possible and will be discussed, since both concepts involved, the fiber laser and the parametric amplifier have the reputation to be immune against thermo-optical effects.

    Since the first report of experimental animal models of myasthenia gravis (MG) with autoantibodies against low-density lipoprotein receptor-related protein 4 (LRP4), there have not been any major reports replicating the pathogenicity of anti-LRP4 antibodies (Abs). Recent clinical studies have cast doubt on the specificity and pathogenicity of anti-LRP4 antibodies for MG, highlighting the need for further research. In this study, we purified antigens corresponding to the extracellular region of human LRP4 stably expressed with chaperones in 293 cells and used these antigens to immunize female A/J mice. Immunization with LRP4 protein caused mice to develop myasthenia having similar electrophysiological and histological features as are observed in MG patients with circulating Abs against muscle-specific kinase (MuSK). Our results clearly demonstrate that active immunization of mice with LRP4 proteins causes myasthenia similar to the MG induced by anti-MuSK Abs. Further experimental and clinical studies are required to prove the pathogenicity of anti-LRP4 Abs in MG patients. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    We used magnetoencephalography to investigate the effect of directed attention on sensorimotor mu (8-12 Hz) response (mu reactivity) to non-painful electrical stimulation of the median nerve in healthy adults. Mu desynchronization in the 10-12 Hz bandwidth is typically observed during higher-order cognitive functions including selective attentional processing of sensorimotor information (Pfurtscheller, Neuper, & Krauz, 2000). We found attention-related sex differences in mu reactivity, with females showing (i) prolonged mu desynchrony when attending to somatosensory stimuli, (ii) attentional modulation of the mu response based on whether attention was directed towards or away from somatosensory stimuli, which was absent in males, and (iii) a trend for greater neuronal excitability of the primary somatosensory region suggesting greater physiological responsiveness to sensory stimulation overall. Our findings suggest sex differences in attentional control strategies when processing somatosensory stimuli, whose salience may be greater for females. These sex differences in attention to somatosensory stimuli may help elucidate the well-documented sex biases in pain processing wherein females typically report greater sensitivity to experimental and clinical pain.

    Waveguides were written in fused silica using both a femtosecond fiber laser with a 1 MHz pulse repetition rate and a femtosecond amplified Ti:sapphire laser with a 1 kHz repetition rate. Confocal Raman and fluorescence microscopy were used to study structural changes in the waveguides written with both systems. A broad fluorescence band, centered at 650 nm, associated with non-bridging oxygen hole center (NBOHC) defects was observed after waveguide fabrication with the MHz laser. With the kHz laser system these defects were only observed for pulse energies above 1 {mu}J. Far fewer NBOHC defects were formed with the MHz laser than with kHz writing, possibly due to thermal annealing driven by heat accumulation effects at 1 MHz. When the kHz laser was used with pulse energies below 1 {mu}J, the predominant fluorescence was centered at 550 nm, a band assigned to the presence of silicon clusters (E{prime}{sub {delta}}). We also observed an increase in the intensity of the 605 cm{sup -1} Raman peak relative to the total Raman intensity, corresponding to an increase in the concentration of 3-membered rings in the lines fabricated with both laser systems.

  13. A Study of J/psi Production at the LEP $e^{+} e{-}$ Collider; and the Implementation of the DELPHI Slow Controls System

    This thesis describes two separate areas of work conducted for the DELPHI detector at LEP. The first concerns the Slow Controls of the DELPHI detector, which enable a single operator to oversee the proper functioning of the apparatus and to diagnose faults as they occur. The hardware and software of this system, as well as their interface to the experiment and the operator, are described. Some conclusions are drawn from seven years' design work and the initial six years' operation of DELPHI. Secondly, a study is made of the production, at e+e- collision centre of mass energies close to the Z0 resonance, of J/psi mesons, decaying to mu+ mu-. J/psi mesons produced via a B-hadron are used to measure the mean B lifetime, tau_B = (1.53 +- 0.11 (stat.) +- 0.06 (syst.)) ps A measurement is also made of the fraction of J/psis produced promptly at the e+e- collision point, N(Z0 -> prompt J/psi X) / N(Z0 -> J/psi X) = (9.6 +- 3.2 (stat.) +- 1.2 (syst.))%. This method is largely model-independent.

    The ALICE experiment at the LHC has studied J/$\\psi$ production at mid-rapidity in pp collisions at $\\sqrt{s}$=7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity $L_{int}$ = 5.6 nb$^{-1}$. The fraction of J/$\\psi$ from the decay of long-lived beauty hadrons was determined for J/$\\psi$ candidates with transverse momentum $p_t$ > 1.3 GeV/c and rapidity |y| 1.3 GeV/c, |y|<0.9) = 7.2 \\pm 0.7(stat.) \\pm 1.0(syst.)^{+ 1.3}_{-1.2}(syst., pol.) \\mu b$. The $p_t$-differential cross section for prompt J/$\\psi$ has also been measured. The cross section for the production of b-hadrons decaying to J/$\\psi$ with transverse momentum greater than 1.3 GeV/c in the rapidity range |y|<0.9 is $\\sigma_{J/\\psi <- h_B}=1.26 +- 0.33(stat.)^{+0.23}_{-0.28}(syst.)\\mu b$. The results are compared to QCD model predictions.

    The pulsed power technology has been applied in particle accelerators and storage rings for over four decades. It is most commonly used in injection, extraction, beam manipulation, source, and focusing systems. These systems belong to the class of repetitive pulsed power. In this presentation, we review and discuss the history, present status, and future challenge of pulsed power applications in high intensity proton accelerators and storage rings.

    The Dutch Fusion-FEM is the prototype of a high-power, long-pulse, rapid-tunable free-electron maser. The target is to generate mm-wave power in a frequency range of 130-260 GHz, e.g. for tokamak heating and diagnostics experiments in fusion devices. For these applications a high system efficiency is needed. The electron beam is first DC-accelerated to the FEL interaction region. The unused electron beam energy is recovered by a DC-decelerator and a three-stage depressed collector. In short-pulse regime, without energy recovery system, 730 kW, 200 GHz of net output power was generated. Single-frequency operation and tunability have been demonstrated. In the present set-up, with the energy recovery system being operational, initial experiments showed a net output power of 110 kW on average and 140 kW peak power at a pulse length of 40 {mu}s. During the full-pulse length, a stable-frequency operation around 170 GHz has been observed.

    This report describes the project that I worked on during my time as a summer student at CERN in summer 2014: A search for the rare decay $B_s \\rightarrow f_2' \\mu^+ \\mu^-$ at the LHCb experiment has been performed using data corresponding to an integrated luminosity $\\mathcal{L} = 3.0 \\text{ fb}^{-1}$. In the Standard Model (SM), this decay is highly suppressed as it proceeds via an electroweak penguin transition. New Physics (NP) effects can enter the loop and influence observables like the branching ratio $\\mathcal{B}$. A theoretical prediction of the branching ratio in the SM is given by $\\mathcal{B}_\\text{th}(B_s \\rightarrow f_2' \\mu^+ \\mu^-) = \\left( 1.8\\,^{+1.1}_{-0.7} \\right) \\cdot 10^{-7}$. We found $N_\\text{obs} = 17.2 \\pm 2.9$ signal candidates using a two dimensional mass fit which is in the same order of magnitude as the theoretical prediction $N_\\text{pred} = 15_{-7}^{+10}$. Though, further systematic effects in the analysis still have to be investigated before converting this into a reliable va...

    The tridentate aminopyridine ligand bearing a bulky tert-butyl substituent at the amine nitrogen, tert-butyl-dipicolylamine (tBuDPA), occupies three coordination sites in six-coordinate complexes of nickel(ii), leaving the remaining three sites available for additional ligand binding and activation. New crystallographically characterized complexes include two mononuclear species with 1:1 metal:ligand complexation: a trihydrate solvate (1.3H(2)O) and a monohydrate biacetonitrile solvate (1.H(2)O.2CH(3)CN). Complexation in the presence of sodium hydroxide results in a bis(mu-hydroxo) complex (2), the bridging hydroxide anions of which are labile and become displaced by methoxide anions in methanol solvent, affording bis-methoxo-bridged (4). Nickel(II) centers in 2 are five-coordinate and antiferromagnetically coupled (with J = -31.4(5) cm(-1), H = -2JS(1)S(2), in agreement with Ni-O-Ni angle of 103.7 degrees). Bridging hydroxide or alkoxide anions in coordinatively unsaturated dinuclear nickel(II) complexes with tBuDPA react as active nucleophiles. 2 readily performs carbon dioxide fixation, resulting in the formation of a bis(mu-carbonato) tetrameric complex (3), which features a novel binding geometry in the form of an inverted butterfly-type nickel-carbonate core. Temperature-dependent magnetic measurements of tetranuclear carbonato-bridged revealed relatively weak antiferromagnetic coupling (J(1) = -3.1(2) cm(-1)) between the two nickel centers in the core of the cluster, as well as weak antiferromagnetic pairwise interactions (J(2) = J(3) = -4.54(5) cm(-1)) between central and terminal nickel ions.

    A number of intense ion beams applications are emerging requiring repetitive high-average-power beams. These applications include ablative deposition of thin films, rapid melt and resolidification for surface property enhancement, advanced diagnostic neutral beams for the next generation of Tokamaks, and intense pulsed-neutron sources. A 200-250 keV, 15 kA, 1 {mu}s duration, 1-30 Hz intense ion beam accelerator is being developed to address these applications. (author). 4 figs., 7 refs.

    The present study utilized a newly developed quantitative immunohistochemical assay to measure changes in {mu} opioid receptor abundance following chronic administration of the opioid receptor antagonist naltrexone. These data were compared with those obtained from {mu} receptor radioligand binding on adjacent tissue sections, in order to determine whether the characteristic antagonist-induced increase in radioligand binding is due to an increase in the total number of {mu} receptors and/or to an increase in the proportion of receptors that are in an active binding conformation in the absence of a change in the total number of receptors. Adult male Sprague-Dawley rats were administered naltrexone, 7-8 mg/kg per day, or saline continuously for seven days by osmotic minipumps, after which time their brains were processed for immunohistochemistry and receptor autoradiography on adjacent fresh frozen tissue sections. Semiquantitative immunohistochemistry was performed using a radiolabelled secondary antibody for autoradiographic determination and a set of radioactive standards. Results demonstrate an overall concordance between the distribution of {mu} opioid receptors as measured by the two different methods with a few exceptions. Following naltrexone administration, {mu} receptor immunoreactivity was significantly higher in the amygdala, thalamus, hippocampus, and interpeduncular nucleus as compared with the saline-treated control animals. [{sup 3}H]D-Ala{sup 2},N-Me-Phe{sup 4},Gly-ol{sup 5}-enkephalin binding to {mu} opioid receptors was significantly higher in the globus pallidus, amygdala, thalamus, hypothalamus, hippocampus, substantia nigra, ventral tegmental area, central gray, and interpeduncular nucleus of the naltrexone-treated rats.These findings indicate that in some brain regions chronic naltrexone exposure increases the total number of {mu} opioid receptors, while in other regions there is an increase in the percent of active receptors without an

    Complete text of publication follows. The Advanced Radiographic Capability (ARC) on the National Ignition Facility (NIF) is designed to produce energetic x-rays in the range of 10-100 keV for backlighting NIF targets. ARC will convert 4 of the 192 NIF beamlines into 8 split beams, delivering laser pulses with adjustable pulse durations from 1 ps to 50 ps at the kilo-Joule level. Adjustable time delays between the 8 beams enable X-ray 'motion-picture' capture with tens-of-picosecond resolution during the critical phases of an ICF shot. The precise alignment of stretcher-compressor pairs in energetic chirped pulse amplification (CPA) systems is tedious and requires several iterations using advanced temporal diagnostics until the shortest pulse durations and highest peak intensities are achieved. For large, energetic Petawatt laser systems with beam sizes up to 40 cm, diffraction gratings in the compressor reach meter-scale size and are difficult to precisely align. We developed a group delay diagnostic which enables accurate, offline measurements of highly dispersive components such as stretchers or compressors with sub-picosecond accuracy. This diagnostic tool enables us to simply measure each dispersive component offline, and balance the dispersion in each beamline. Furthermore it allows exactly matching the dispersion of ARC's eight, independent four-grating compressors, which is critical for producing eight identical pulses. ARC utilizes a unique, folded compressor design for maximum compactness; two 5.5 m long vacuum vessels house 8 compressors with 91 cm x 45 cm multilayer, dielectric gratings. The group delay diagnostic utilizes the phase-shift technique for measuring the dispersion characteristics of each individual element, e.g. grating stretcher, chirped fiber Bragg grating, grating compressor, material dispersion, or an entire laser system. The system uses an amplitude modulated, highly-stable, single-frequency laser, which is scanned over the spectral

    A systematic optimization of p-type Sb{sub 2}Te{sub 3} thermoelectric films made by potentiostatic electrodeposition on Au and stainless steel substrates is presented. The influence of the preparative parameters of deposition voltage, concentration, and the deposition method are investigated in a nitric acid solution. As a postdeposition step, the influence of annealing the films is investigated. The use of a potential-controlled millisecond-pulsed deposition method could improve both the morphology and the composition of the films. The samples are characterized in terms of composition, crystallinity, Seebeck coefficient, and electrical resistivity. Pulsed-deposited films exhibit Seebeck coefficients of up to 160 {mu}V K{sup -1} and an electrical conductivity of 280 S cm{sup -1} at room temperature, resulting in power factors of about 700 {mu}W m{sup -1} K{sup -2}. After annealing, power factors of maximum 852 {mu}W m{sup -1} K{sup -2} are achieved. Although the annealing of DC-deposited films significantly increased the power factor, they do not reach the values of the pulsed-deposited films in the preannealing state. Structural analysis is performed with X-ray diffraction and shows the crystalline structure of Sb{sub 2}Te{sub 3} films. The performance is tuned by annealing of deposited films up to 300 C under He atmosphere while performing in-situ X-ray diffraction and resistivity measurements. The chemical analysis of the films is performed by inductively coupled plasma optical emission spectroscopy (ICP-OES) as well as scanning electron microscope energy dispersive X-ray analysis (SEM-EDX).

The BLT films showed well-saturated polarization-electric field curves whose remnant polarizations were 16.1 mu C/cm sup 2 , 27.8 mu C/cm sup 2 , 19.6 mu C/cm sup 2 , and 2.7 mu C/cm sup 2 , respectively, for x=0.25, 0.05, 0.75, and 1.00. The fatigue characteristics became better with increasing x up to 0.75. The Au/BLT/Pt capacitor with a La concentration of 0.50 showed an interesting dependence of the remanent polarization on the number of repetitive read/write cycles. On the other hand, the capacitor with a La concentration of 0.75 showed fatigue-free characteristics.

    Viral warts are common infectious skin disease induced by human papillomavirus (HPV). But the treatment of recalcitrant warts is still challenging. In this study, we compared the effectiveness of pulsed dye laser (PDL) and long pulsed Nd:YAG (LPNY) laser in the treatment of recalcitrant viral warts. We retrospectively analyzed the medical records of patients with recalcitrant warts treated with laser therapy between January 2013 and February 2016. Seventy-two patients with recalcitrant warts were evaluated. Thirty-nine patients were treated with pulsed dye laser and thirty-three patients were treated with LPNY laser. The following parameters were used: PDL (spot size, 7 mm; pulse duration, 1.5 ms; and fluence, 10-14 J/cm 2 ) and LPNY (spot size, 5 mm; pulse duration, 20 ms; and fluence, 240-300 J/cm 2 ). Complete clearance of two patients (5.1%) in PDL group, and three patients (9.1%) in LPNY group were observed without significant side effects. The patients who achieved at least 50% improvement from baseline were 20 (51.3%) in PDL and 22 (66.7%) in LPNY, respectively. This research is meaningful because we compared the effectiveness of the PDL and LPNY in the recalcitrant warts. Both PDL and LPNY laser could be used as a safe and alternative treatment for recalcitrant warts.

    We revisit the calculation of the long-distance contribution to the muon-polarization asymmetry \\Delta_{LR}, which arises, in K^+\\to\\pi^+\\mu^+\\mu^-, from the two-photon intermediate state. The parity-violating amplitude of this process, induced by the local anomalous K^+\\pi^-\\gamma^*\\gamma^* transition, is analysed; unfortunately, one cannot expect to predict its contribution to the asymmetry by using chiral perturbation theory alone. Here we evaluate this amplitude and its contribution to \\Delta_{LR} by employing a phenomenological model called the FMV model, in which the utility of the vector and axial-vector resonances exchange is important to soften the ultraviolet behaviour of the transition. We find that the long-distance contribution is of the same order of magnitude as the standard model short-distance contribution.

    We report the high power acousto-optically Q-switched operation of a dual-end-pumped Ho:YAG laser at room temperature. For the Q-swithched mode, a maximum pulse energy of 2.4 mJ and a minimum pulse width of 23 ns at the repetition rate of 10 kHz are achieved, resulting in a peak power of 104.3 kW. The beam quality factor of M{sup 2} {approx} 1.5, which is demonstrated by a knife-edge method. In addition, the Ho:YAG laser is employed as a pumping source of ZGP optical parametric oscillator, and its total average output power is 13.2 W at 3.9 {mu}m and 4.4 {mu}m with a slope efficiency of 68.4%.

    The plasma focus is a pulsed neutron source especially suited for applications because it reduces the danger of contamination of conventional isotopic radioactive sources. As first stage of a program to design a repetitive pulsed neutron generator for industrial applications we constructed two very small plasma focus operating at an energy level of the order of a) tens of joules (PF-50J, 160nF capacitor bank, 20-35 kV, 32-100J, ∼150ns first quarter of period) and b) hundred of joules (PF-400J, 880nF, 20-35kV, 176-539J, ∼300ns first quarter of period). In this article we present results related to design and construction of these small plasma foci (PF-50J and PF-400J). Neutron yield vs. deuterium. pressure has been obtained, a maximum emission of the order of 7x10 4 and 10 6 neutrons per shot has been measured in the PF-50J and PF-400J respectively (author)

    The MSR (muonium spin rotation) technique was used to measure the chemical reaction rate for ..mu.. + F/sub 2/ ..-->.. ..mu..F + F in N/sub 2/ moderator at approximately 1 atm from 295 to 383 K giving the Arrhenius expression: log/sub 10/k (l/mole s) = (10.83+-0.20) - (200+-50)/T, with k = (1.46+-0.11) X 10/sup 10/ l/mole s at 300 K. This is a least 6.8 times the room temperature rate constant for the analogous H atom reaction. The measured activation energy and enhancement over the H reaction rate are indicative of significant tunnelling in the Mu reaction, in agreement with the recent collinear quantum mechanical calculations of Connor et al.

    Results are reported of detailed numerical studies of Trichel pulse formation for dry air in short-gap coronas. Continuity equations for electrons, positive and negative ions, and the Poisson equation averaged over the current cross section were solved numerically with appropriate boundary conditions. The results of numerical simulation make it possible to analyze in detail the trailing edge of the Trichel pulse and the inter-pulse pause determining the period between pulses. In particular, the variations of the total number of negative ions in the corona spacing occurring under typical conditions of a pulsating corona, proved to be quite insignificant. A comparison with experiments demonstrated a reasonable agreement both for the shape of the pulse and for the average characteristics of the negative corona. (J.U.)

    A 1064 nm, 1 mJ pulsed fiber MOPA module, housed in 16"x14"x2.5" package for application in a lunar and planetary in-situ surface dating instrument is demonstrated. The module is based on a three-stage MOPA with a 60 μm core tapered fiber terminal amplifier. The master oscillator and first two preamplifier stages, which generate 20 μJ pulses, are all contained on a 13"x11"x1" board. Several improvements to the electronic signal control were instrumental to the laser development, including bipolar drive of the phase modulator for SBS suppression, shaping of the seed pulse to compensate pulse steepening, and pulsed operation of the power amplifier pump to reduce spontaneous emission at low pulse repetition frequency. The packaged laser runs at a repetition rate of 10 kHz and generates 10 ns pulses at 1 mJ with a 40 GHz linewidth, an M2 1.2 beam quality, and an 18 dB polarization extinction ratio. The modular design enables seven independent lasers to be stacked in a 20"x18"x16.25" enclosure, supporting a path towards a fiber laser based LARIMS for advanced materials characterization and chronological dating in harsh and remote environments.

    2010-01-01

    The analysis of the penguin decay Bd->K*MuMu at LHCb can act as a laboratory for the discovery and understanding of new physics. Through the Operator Product Expansion, the decay kinematics are well understood in both the Standard Model and in a large range of new physics scenarios. The theoretical errors from QCD effects can be characterized and a set of observables have been derived which minimise their influence in measurements. We will describe how these measurements can be made in LHCb with special emphasis on what can be done with a first run of the LHC with a few hundred pb-1 of integrated luminosity.

  4. Quantum theory of NMR adiabatic pulses and their applications

    Recently explosive developments of in vivo NMR spectroscopy (NMRS) and imaging (NMRI) in biological and medical sciences have resulted in the establishment of NMR as one of the most advanced major technique in life sciences. These developments have created huge demands for a variety of NMR adiabatic pulses with play a very important role in NMR experiments in vivo. In order to develop new NMR adiabatic pulses, a rigorous systematical quantum theory for this kind of pulses is greatly needed. Providing such a theory is one of the important goals of this dissertation. Quantum density matrix theory and product operator method have been used throughout this dissertation. Another goal, which is the major goal of this thesis research, is to use the quantum theory as a guide to develop new NMR adiabatic pulses and their applications. To fill this goal, a technique to construct a new type of adiabatic pulses, narrow band selective adiabatic pulses, has been invented, which is described through the example of constructing an adiabatic DANTE inversion pulse. This new adiabatic pulse is the first narrow band selective adiabatic pulses: Adiabatic homonuclear and heteronuclear spectral editing sequences. Unique to the first pulse sequence is a B 1 -field filter which is built by using two non-refocusing adiabatic full passage pulses to refocus the wanted signal and dephase unwanted signals. This extra filter greatly enhance the editing efficiency. Unlike commonly used heteronuclear spectral editing sequences which depend on the polarization transfer or spectral subtraction by phase cycling techniques, the second pulse sequences accomplishes the editing of heteronuclear J-coupled signals based on the fact that this sequence is transparent to the uncoupled spins and is equivalent a 90 degrees excitation pulse to the heteronuclear J-coupled spins. Experimental results have confirmed the ability of spectral editing with these two new sequences

    We present mathematical models for temporally and spectrally partially coherent pulse trains with Laguerre-Gaussian and Hermite-Gaussian Schell-model statistics as extensions of the standard Gaussian Schell model for pulse trains. We derive propagation formulas of both classes of pulsed fields in linearly dispersive media and in temporal optical systems. It is found that, in general, both types of fields exhibit time-domain self-splitting upon propagation. The Laguerre-Gaussian model leads to multiply peaked pulses, while the Hermite-Gaussian model leads to doubly peaked pulses, in the temporal far field (in dispersive media) or at the Fourier plane of a temporal system. In both model fields the character of the self-splitting phenomenon depends both on the degree of temporal and spectral coherence and on the power spectrum of the field.

    A compact L-band sealed-tube magnetically insulated transmission line oscillator (MILO) has been developed that does not require bulky external vacuum pump for repetitive operations. This device with a ceramic insulated vacuum interface, a carbon fiber array cathode, and non-evaporable getters has a base vacuum pressure in the low 10-6 Pa range. A dynamic 3-D Monte-Carlo model for the molecular flow movement and collision was setup for the MILO chamber. The pulse desorption, gas evolution, and pressure distribution were exactly simulated. In the 5 Hz repetition rate experiments, using a 600 kV diode voltage and 48 kA beam current, the average radiated microwave power for 25 shots is about 3.4 GW in 45 ns pulse duration. The maximum equilibrium pressure is below 4.0 × 10-2 Pa, and no pulse shortening limitations are observed during the repetitive test in the sealed-tube condition.

    Interactions of 209-GeV muons within an instrumented magnetized-steel calorimeter have produced 4374 +- 87 ..mu../sup +/..mu../sup -/ pairs from J/psi decay, corresponding to the cross section sigma(..mu..N ..-->.. ..mu.. psi X) = 0.64 +- 0.10 nb. These interactions are classified as either elastic (sigma = 0.36 +- 0.07 nb) or inelastic (sigma = 0.28 +- 0.06 nb) based primarily on the calorimetric determination of E/sub X/. The cross section for elastic psi production by virtual photons, sigma/sub eff/(..gamma../sub V/N), rises with energy nu as log nu. Its dependence on Q/sup 2/ fits the vector-meson dominance form P(..lambda..) = (1 + Q/sup 2//..lambda../sup 2/)/sup -2/, with ..lambda.. = (2.0 - 2.4) +- 0.15 GeV, where the spread in values arises from considering the possibility of a Q/sup 2/ dependence in the decay angular distribution W (theta,phi) and in the nuclear shadowing factor. We find that W(theta,phi) is consistent with the form expected if the reaction ..gamma../sub V/N ..-->.. psiN conserves helicity in the s channel through natural-parity exchange in the t channel. After correction for nuclear effects, d sigma/sub eff//dt is described by the sum of two exponential terms in t, with average t slope b = 2.56 (+0.35 or - 0.32). The photon-gluon fusion (..gamma..g ..-->.. psi) perturbative quantum chromodynamic model for psi production provides an excellent description of the nu dependence of sigma/sub eff/, but cannot simultaneously explain the observed cross section and value of ..lambda... The differential cross section d/sup 2/sigma/sub eff//dzdp/sub perpindicular//sup 2/ for inelastically produced psi's rises approximately linearly with elasticity z identical with E/sub psi//nu. The p/sub perpendicular//sup 2/ dependence is flatter than that of d sigma/dt for elastic events, with average p/sub perpendicular//sup 2/ slope b = 1.46 +- 0.10. The Q/sup 2/ dependence of sigma/sub eff/ is that of P(..lambda..) with ..lambda.. = 3.0 +- 0.2 GeV, and

    A dense plasma focus (DPF) is a compact plasma gun that produces high energy ion beams, up to several MeV, through strong potential gradients. Motivated by particle-in-cell simulations, we have tried a series of hollow anodes on our kJ-class DPF. Each anode has varying hollow sizes, and has been studied to optimize ion beam production in Helium, reduce anode sputter, and increase neutron yields in deuterium. We diagnose the rate at which electrode material is ablated and deposited onto nearby surfaces. This is of interest in the case of solid targets, which perform poorly in the presence of sputter. We have found that the larger the hollow radius produces more energetic ion beams, higher neutron yield, and sputter less than a flat top anode. A complete comparison is presented.

    By seeding amplifying plasmas pumped with the so-called Transient collisionnal excitation scheme, the amplified pulse seems to be limited to an energy of several 10's of μJ. Aiming to attain several mJ, we study the seeding of plasma pumped by long laser pulse. Thanks to our time-dependent Maxwell-Bloch code, we demonstrate that direct seeding with femtosecond pulse is inefficient. We also study the amplification of pulse train with the drawback of re-synchronizing the pulses. We proposed and studied the amplification of high harmonic seed stretched by a grating pair, amplified finally compressed. We consider off-axis diffraction on the gratings for maximizing their efficiency. Considering the phase deformation induced by the amplification and the spectral narrowing the final pulse is 230 fs in duration and 5 mJ.

    We have studied the transverse-momentum ($p_{\\rm T}$) dependence of the inclusive J/$\\psi$ production in p-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV, in three center-of-mass rapidity ($y_{\\rm cms}$) regions, down to zero $p_{\\rm T}$. Results in the forward and backward rapidity ranges ($2.03 < y_{\\rm cms} < 3.53$ and $-4.46 < y_{\\rm cms} < -2.96$) are obtained by studying the J/$\\psi$ decay to $\\mu^+\\mu^-$, while the mid-rapidity region ($-1.37 < y_{\\rm cms} < 0.43$) is investigated by measuring the ${\\rm e}^+{\\rm e}^-$ decay channel. The $p_{\\rm T}$ dependence of the J/$\\psi$ production cross section and nuclear modification factor are presented for each of the rapidity intervals, as well as the J/$\\psi$ mean $p_{\\rm T}$ values. Forward and mid-rapidity results show a suppression of the J/$\\psi$ yield, with respect to pp collisions, which decreases with increasing $p_{\\rm T}$. At backward rapidity no significant J/$\\psi$ suppression is observed. Theoretical models including a combinat...

    Oxidative processes have the ability to influence mu-calpain activity. In the present study the influence of oxidation on activity and autolysis of mu-calpain was examined. Furthermore, LC-MS/MS analysis was employed to identify and characterize protein modifications caused by oxidation. The results revealed that the activity of mu-calpain is diminished by oxidation with H2O2 in a reversible manner involving cysteine and that the rate of autolysis of mu-calpain concomitantly slowed. The LC-MS/MS analysis of the oxidized mu-calpain revealed that the amino acid residues 105-133 contained a disulfide bond between Cys(108) and Cys(115). The finding that the active site cysteine in mu-calpain is able to form a disulfide bond has, to our knowledge, not been reported before. This could be part of a unique oxidation mechanism for mu-calpain. The results also showed that the formation of the disulfide bond is limited in the control (no oxidant added), and further limited in a concentration-dependent manner when beta-mercaptoethanol is added. However, the disulfide bond is still present to some extent in all conditions indicating that the active site cysteine is potentially highly susceptible to the formation of this intramolecular disulfide bond.

    The PHENIX experiment at the Relativistic Heavy Ion Collider has measured J/{psi} production in proton-proton collisions at {radical}(s)= 200 GeV using data from the 2001-2002 collider run. Distributions of rapidity and transverse momentum are presented and compared with theoretical predictions. The total cross section and mean p{sub T} are calculated and compared to fixed-target results. The total J/{psi} cross section is 4.0{+-}0.6(stat){+-}0.6(sys){+-}0.4(abs){mu}b. The mean p{sub T} is 1.80{+-}0.23(stat){+-}0.16(sys) GeV/c. (orig.)

  14. Microencapsulation of silicon cavities using a pulsed excimer laser

    2012-06-07

    This work presents a novel low thermal-budget technique for sealing micromachined cavities in silicon. Cavities are sealed without deposition, similar to the silicon surface-migration sealing process. In contrast to the 1100°C furnace anneal required for the migration process, the proposed technique uses short excimer laser pulses (24ns), focused onto an area of 23mm 2, to locally heat the top few microns of the substrate, while the bulk substrate remains near ambient temperature. The treatment can be applied to selected regions of the substrate, without the need for special surface treatments or a controlled environment. This work investigates the effect of varying the laser pulse energy from 400 mJ cm 2to 800 mJ cm 2, the pulse rate from 1Hz to 50Hz and the pulse count from 200 to 3000 pulses on sealing microfabricated cavities in silicon. An analytical model for the effect of holes on the surface temperature distribution is derived, which shows that much higher temperatures can be achieved by increasing the hole density. A mechanism for sealing the cavities is proposed, which indicates how complete sealing is feasible. © 2012 IOP Publishing Ltd.

    The U/n process has been used to introduce quasi-columnar pinning centers into Nd123, textured in 1% O{sub 2}, 99% Ar. The process involves adding {sup 235}U to precursor powders of the superconductor, texturing, and irradiating with thermal neutrons. The two resulting ions, from each nuclear fission, cause aligned discontinuous electronic damage of length {approx}5.4 {mu}m, which acts as a pinning center. Best results for J{sub c} require U deposits spaced by s{<=}5.4 {mu}m. This has been achieved by deposits containing two foreign elements, U and Zr, and three native elements. The deposits of UZrNdBaO and Nd422 refined by the Zr, act as additional non-aligned pinning centers. The U/n process increases J{sub c} by a factor R{sub J}{>=}10, to values of J{sub c}{approx}274 kA/cm{sup 2} at T=77 K, B=666 G.

  16. Low power arcjet thruster pulse ignition

    1987-01-01

    An investigation of the pulse ignition characteristics of a 1 kW class arcjet using an inductive energy storage pulse generator with a pulse width modulated power converter identified several thruster and pulse generator parameters that influence breakdown voltage including pulse generator rate of voltage rise. This work was conducted with an arcjet tested on hydrogen-nitrogen gas mixtures to simulate fully decomposed hydrazine. Over all ranges of thruster and pulser parameters investigated, the mean breakdown voltages varied from 1.4 to 2.7 kV. Ignition tests at elevated thruster temperatures under certain conditions revealed occasional breakdowns to thruster voltages higher than the power converter output voltage. These post breakdown discharges sometimes failed to transition to the lower voltage arc discharge mode and the thruster would not ignite. Under the same conditions, a transition to the arc mode would occur for a subsequent pulse and the thruster would ignite. An automated 11 600 cycle starting and transition to steady state test demonstrated ignition on the first pulse and required application of a second pulse only two times to initiate breakdown.

    Hydrogen absorber R and D for the MuCool Collaboration is actively pushing ahead on two parallel and complementary fronts. The continuing LH2 engineering and technical developments by the MuCool group, conducted by ICAR institutions (NIU, IIT and UIUC), the University of Mississippi and Oxford University in cooperation with Fermilab, are summarized here, including plans for the first tests of an absorber prototype from Osaka University and KEK cooled by internal convection at the newly constructed FNAL MuCool Test Area (MTA). Designs for the high-power test of another absorber prototype (employing external heat exchange) are complete and the system will be installed by summer 2004. A convection-cooled absorber design is being developed for the approved MICE cooling demonstration at Rutherford Appleton Laboratory

    Over the past decade, development of high-energy ultrafast laser sources has led to important breakthroughs in attoscience and strong-field physics study in atoms and molecules. Coherent pulse synthesis of few-cycle high-energy laser pulse is a promising tool to generate isolated attosecond pulses via high harmonics generation (HHG). An effective way to extend the HHG cut-off energy to higher values is making use of long mid-infrared (MIR) driver wavelength, as the ponderomotive potential scales quadratically with wavelength. If properly scaled in energy to multi-mJ level and few-cycle duration, such pulses provide a direct path to intriguing attoscience experiments in gases and solids, which even permit the realization of bright coherent table-top HHG sources in the water-window and keV X-ray region. However, the generation of high-intensity long-wavelength MIR pulses has always remained challenging, in particular starting from high-energy picosecond 2-μm laser driver, that is suitable for further energy scaling of the MIR pulses to multi-mJ energies by utilizing optical parametric amplifiers (OPAs). In this thesis, a front-end source for such MIR OPA is presented. In particular, a novel and robust strong-field few-cycle 2-μm laser driver directly from picosecond Ho:YLF laser and utilizing Kagome fiber based compression is presented. We achieved: a 70-fold compression of 140-μJ, 3.3-ps pulses from Ho:YLF amplifier to 48 fs with 11 μJ energy. The work presented in this thesis demonstrates a straightforward path towards generation of few-cycle MIR pulses and we believe that in the future the ultrafast community will benefit from this enabling technology. The results are summarized in mainly four parts: The first part is focused on the development of a 2-μm, high-energy laser source as the front-end. Comparison of available technology in general and promising gain media at MIR wavelength are discussed. Starting from the basics of an OPA, the design criteria

    Social cognitive difficulties are common in the acute phase of bipolar disorder and, to a lesser extent, during the euthymic stage, and imaging studies of social cognition in euthymic bipolar disorder have implicated mirror system brain regions. This study aimed to use a novel multimodal approach (i.e., including both transcranial magnetic stimulation (TMS) and electroencephalogram (EEG)) to investigate mirror systems in bipolar disorder. Fifteen individuals with euthymic bipolar disorder and 16 healthy controls participated in this study. Single-pulse TMS was applied to the optimal site in the primary motor cortex (M1), which stimulates the muscle of interest during the observation of hand movements (goal-directed or interacting) designed to elicit mirror system activity. Single EEG electrodes (C3, CZ, C4) recorded mu rhythm modulation concurrently. Results revealed that the patient group showed significantly less mu suppression compared to healthy controls. Surprisingly, motor resonance was not significantly different overall between groups; however, bipolar disorder participants showed a pattern of reduced reactivity on some conditions. Although preliminary, this study indicates a potential mirror system deficit in euthymic bipolar disorder, which may contribute to the pathophysiology of the disorder.

  1. Effect of monoclonal antibodies (MoAb) to class I and class II HLA antigens on lectin- and MoAb OKT3-induced lymphocyte proliferation.

    We have examined the effect of several monoclonal antibodies (MoAb) to monomorphic determinants of class II HLA antigens, and MoAb to monomorphic determinants of class I HLA antigens and to beta-2-microglobulin (beta 2-mu) on lectin- and MoAb OKT3-induced proliferation of human peripheral blood mononuclear cells (PBMNC) and cultured T cells (CTC). Some, but not all, anti-class II HLA MoAb inhibited the proliferative response of PBMNC to MoAb OKT3 and pokeweed mitogen (PWM). The degree of inhibitory effect varied considerably. This effect was not limited to anti-class II HLA MoAb since anti-class I HLA MoAb and anti-beta 2-mu MoAb also inhibited MoAb OKT3- or PWM-induced proliferative responses. In contrast, the response of PBMNC to phytohemagglutinin (PHA) and concanavalin A (Con A) was not blocked by any anti-class II HLA MoAb. However, some anti-class II HLA MoAb also inhibited the proliferative response of CTC plus allogeneic peripheral blood adherent accessory cells (AC) to PHA or Con A as well as to MoAb OKT3 or PWM. This may be attributable to the substantially greater class II HLA antigen expression by CTC than by fresh lymphocytes. Pretreatment of either CTC or AC with anti-class II HLA MoAb inhibited OKT3-induced proliferation. In contrast, pretreatment of CTC, but not AC, with anti-class I HLA MoAb inhibited the proliferative response of CTC to OKT3. Pretreatment of CTC with anti-class I HLA MoAb inhibited PHA-, Con A and PWM-induced proliferation, to a greater degree than the anti-class II HLA MoAb. It appears as if lymphocyte activation by different mitogens exhibits variable requirements for the presence of cells expressing major histocompatibility determinants. Binding of Ab to membrane markers may interfere with lymphocyte-AC cooperation, perhaps by inhibiting binding of mitogens to their receptors or by interfering with lymphocyte and AC function. We also have examined the role of class II HLA antigens on CTC by depleting class II HLA-positive cells

    An instrument for measuring solution conductance using the bipolar pulse technique is described. The instrument is capable of measuring conductances in the range of 5x10{sup -9}-10{Omega}{sup -1} with 1% accuracy or better in as little as 32 {mu}s. Accuracy of 0.001-0.01% is achievable over the range 1x10{sup -6}-1{Omega}{sup -1}. Circuitry and software are described that allow the instrument to adjust automatically the pulse height, pulse duration, excitation mode (current or voltage pulse) and data acquisition mode (sampled or integrated) to acquire data of optimum accuracy and precision. The urease-catalyzed decomposition of urea is used to illustrate the versality of the instrument, and other applications are cited. (author). 60 refs.; 7 figs.; 2 tabs.

    A pulsed diode electron gun delivering 500 mA current at 40 kV is described. The gun geometry is optimized using the Electron Trajectory Program EGUN at higher scaling factors by choosing the closest converging starting surface. The effect of an annular gap between cathode and focusing electrode on beam behaviour is compensated by using a suitable focusing electrode. The estimated perveance is 0.065 {mu}perv and the normalized emittance is within 5{pi} mm mrad. The variation in current density at the cathode has been limited to within 10% across the face of the cathode. Salient features of the pulsed power supply and an insight of its interconnection with the gun are presented. The current measured at the Faraday cup is in agreement with the designed perveance.

    XTE J1946+274 = GRO J1944+26 is a 15.8-s X-ray pulsar discovered simultaneously by the Rossi X-ray Timing Explorer (RXTE) and the Burst and Transient Source Experiment (BATSE) in September 1998. Follow-up optical/IR observations resulted in the discovery of a Be star companion. Our pulse timing analysis of BATSE and RXTE data indicates that the orbital period is approximately 169 days. Since its discovery in 1998, XTE J1946+274 has undergone 13 outbursts. These outbursts axe not regularly spaced. They occur approximately twice per orbit and are not locked in orbital phase, unlike most Be/X-ray transient systems. A possible explanation for this is a global-one armed oscillation or density perturbation propagating rapidly in the Be star's disk. We will investigate radial velocity variations in the central peak of the H-alpha line to look for evidence of such a perturbation. From 2001 March-September, we regularly monitored XTE J1946+274 with the RXTE PCA. We will demonstrate that the spectrum appears to be varying with orbital phase, based on the 2001 and 1998 RXTE PCA observations. We will also present histories of pulsed frequency and flux.

    Abrams, R. J.

    2012-03-01

    Mu2e at Fermilab will search for charged lepton flavor violation via the coherent conversion process μ- N → e- N with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process. The experiment's sensitivity offers discovery potential over a wide array of new physics models and probes mass scales well beyond the reach of the LHC. We describe herein the conceptual design of the proposed Mu2e experiment. This document was created in partial fulfillment of the requirements necessary to obtain DOE CD-1 approval, which was granted July 11, 2012.

    We report the discovery of an X-ray periodicity of {approx}265.3 ms from a deep XMM-Newton observation of the radio-quiet {gamma}-ray pulsar, PSR J2021+4026, located at the edge of the supernova remnant G78.2+2.1 ({gamma}-Cygni). The detected frequency is consistent with the {gamma}-ray pulsation determined by the observation of the Fermi Gamma-ray Space Telescope at the same epoch. The X-ray pulse profile resembles the modulation of a hot spot on the surface of the neutron star. The phase-averaged spectral analysis also suggests that the majority of the observed X-rays have thermal origins. This is the third member in the class of radio-quiet pulsars with significant pulsations detected from both X-ray and {gamma}-ray regimes.

    The production of J/ψ mesons in proton-proton collisions at √(s)=7 ∝ TeV is studied with the LHCb detector at the LHC. The differential cross-section for prompt J/ψ production is measured as a function of the J/ψ transverse momentum p T and rapidity y in the fiducial region p T in[0;14]∝GeV mskip-2μ mskip-1mu c and y element of [2.0;4.5]. The differential cross-section and fraction of J/ψ from b-hadron decays are also measured in the same p T and y ranges. The analysis is based on a data sample corresponding to an integrated luminosity of 5.2 pb -1 . The measured cross-sections integrated over the fiducial region are for prompt J/ψ production and for J/ψ from b-hadron decays, where the first uncertainty is statistical and the second systematic. The prompt J/ψ production cross-section is obtained assuming no J/ψ polarisation and the third error indicates the acceptance uncertainty due to this assumption. (orig.)

    The necessary and sufficient conditions are found for the membership of Lee algebras to PR algebra class, to algebras with commutation relations of [Hsub(i), Hsub(j)]=rsub(ij)Hsub(i) (i< j) type. Due to this, a criterion is obtained for the membership of the Lee froups to PR group classes, connected and simply connected Lee groups, which Lee algebras are PR algebras

    We make a frequentist analysis of the parameter space of the CMSSM and NUHM1, using a Markov Chain Monte Carlo (MCMC) with 95 (221) million points to sample the CMSSM (NUHM1) parameter spaces. Our analysis includes the ATLAS search for supersymmetric jets + MET signals using ~ 5/fb of LHC data at 7 TeV, which we apply using PYTHIA and a Delphes implementation that we validate in the relevant parameter regions of the CMSSM and NUHM1. Our analysis also includes the constraint imposed by searches for B_s to mu+mu- by LHCb, CMS, ATLAS and CDF, and the limit on spin-independent dark matter scattering from 225 live days of XENON100 data. We assume M_h ~ 125 GeV, and use a full set of electroweak precision and other flavour-physics observables, as well as the cold dark matter density constraint. The ATLAS 5/fb constraint has relatively limited effects on the 68 and 95% CL regions in the (m_0, m_1/2) planes of the CMSSM and NUHM1. The new B_s to mu+mu- constraint has greater impacts on these CL regions, and also impa...

    Based on the transmission line code TLCODE, a 1D circuit model for a transmission-line impedance transformer was developed and the simulation results were compared with those in the literature. The model was used to quantify the efficiencies of voltage-transport, energy-transport and power-transport for a transmission-line impedance transformer as functions of ψ (the ratio of the output impedance to the input impedance of the transformer) and Γ (the ratio of the pulse width to the one-way transit time of the transformer) under a large scale of m (the coefficient of the generalized exponential impedance profile). Simulation results suggest that with the increase in Γ, from 0 to ∞, the power transport efficiency first increases and then decreases. The maximum power transport efficiency can reach 90% or even higher for an exponential impedance profile (m = 1). With a consideration of dissipative loss in the dielectric and electrodes of the transformer, two representative designs of the water-insulated transformer are investigated for the next generation of petawatt-class z-pinch drivers. It is found that the dissipative losses in the electrodes are negligibly small, below 0.1%, but the dissipative loss in the water dielectric is about 1% to 4%. (fusion engineering)

    The ablation spot area and impulse characteristics of various polymers were experimentally investigated against burst irradiation of Nd: YLF laser pulses with a pulse repetition frequency of 1 kHz, wavelength of 1047 nm, temporal pulse width of 10 ns, and single-pulse fluence of 6.1 J/cm2 to 17.1 J/cm2. The dependences of ablation area on the pulse energy from 0.72 to 7.48 mJ and the number of pulses from 10 pulses to 1000 pulses were investigated. In order to characterize their impulse performance as a function of fluence, which should not depend on ablation material, an effective ablation spot area was defined as that obtained against aluminum, 1050 A, as the reference material. An impulse that resulted from a single burst of 200 pulses was measured with a torsion-type impulse stand. Various impulse dependences on the fluence, which were not readily predicted from the optical properties of the material without ablation, were obtained. By fitting the experimentally measured impulse performance to Phipps and Sinko's model in the vapor regime, the effective absorption coefficient with laser ablation was evaluated, thereby resulting in three to six orders of magnitude larger than that without ablation. Among the polymers examined using polytetrafluoroethylene (PTFE) as the best volume absorbers, the highest momentum coupling coefficient of 66 μNs/J was obtained with an effective absorption coefficient more than six times smaller than that of the other polymers.

    An apparatus is described in which a ruby-pumped dye laser is used to induce transitions from the 2S to the 2P levels of the muonic ion ( mu He)/sup +/. The dye laser supplies infra-red radiation pulses in the wavelengths (8040-8180) AA, at typical repetition rates of 1 pulse every 4 s, with an energy release per pulse of 300 mJ for 1.2 J pumping energy. A special synchronization procedure is followed to trigger the laser in close coupling with the incoming muon beam which is stopped in a helium target at pressures between 40 and 50 atm. The other performances of the device are fully discussed with reference both to the laser facility and to the special high-pressure helium target. (23 refs).

    1995-01-01

    Progress in electronic power conversion technology is making possible a new class of induction linacs that can operate at extremely high repetition rates. Advances in insulator technology, pulse forming line design and switching may also lead to a new type of high current accelerator with accelerating gradients at least an order of magnitude greater than those attainable today. The evolution of the induction accelerator pulsed power system will be discussed along with some details of these emerging technologies which are at the frontiers of accelerator technology

    1997-01-01

    GRO J2058+42, a transient 198 second x-ray pulsar, was discovered by the Burst and Transient Source Experiment (BATSE) on the Compton Gamma-Ray Observatory (CGRO), during a "giant" outburst in 1995 September-October. The total flux peaked at about 300 mCrab (20-50 keV) as measured by Earth occultation. The pulse period decreased from 198 s to 196 s during the 46-day outburst. The pulse shape evolved over the course of the outburst and exhibited energy dependent variations. BATSE observed five additional weak outbursts from GRO J2058+427 each with two week duration and peak pulsed flux of about 15 mcrab (20-50 keV), that were spaced by about 110 days. An observation of the 1996 November outburst by the Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) localized the source to within a 4' radius error circle (90% confidence) centered on R.A. = 20 h 59 m.0, Decl. = 41 deg 43 min (J2000). Additional shorter outbursts with peak pulsed fluxes of about 8 mCrab were detected by BATSE halfway between the first four 15 mCrab outbursts. The RXTE All-Sky Monitor detected 8 weak outbursts with approximately equal durations and intensities. GRO J2058+42 is most likely a Be/X-ray binary that appears to outburst at periastron and apastron. No optical counterpart has been identified to date and no x-ray source was present in the error circle in archival ROSAT observations.

    The angular distribution and differential branching fraction of the decay $B^{0} \\to K^{*0} \\mu^{+}\\mu^{-}$ are studied using a data sample, collected by the LHCb experiment in $pp$ collisions at $\\sqrt{s}=7\\,{\\rm TeV}$, corresponding to an integrated luminosity of $1.0\\,{\\rm fb}^{-1}$. Several angular observables are measured in bins of the dimuon invariant mass squared, $q^{2}$. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be $q_{0}^{2} = 4.9 \\pm 0.9 \\,{\\rm GeV}^{2}/c^{4}$, where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.

  3. Drilling of Copper Using a Dual-Pulse Femtosecond Laser

    Full Text Available The drilling of copper using a dual-pulse femtosecond laser with wavelength of 800 nm, pulse duration of 120 fs and a variable pulse separation time (0.1–150 ps is investigated theoretically. A one-dimensional two-temperature model with temperature-dependent material properties is considered, including dynamic optical properties and the thermal-physical properties. Rapid phase change and phase explosion models are incorporated to simulate the material ablation process. Numerical results show that under the same total laser fluence of 4 J/cm2, a dual-pulse femtosecond laser with a pulse separation time of 30–150 ps can increase the ablation depth, compared to the single pulse. The optimum pulse separation time is 85 ps. It is also demonstrated that a dual pulse with a suitable pulse separation time for different laser fluences can enhance the ablation rate by about 1.6 times.

    The mechanisms of emission and changes in rotation frequency (“glitching”) of the Vela pulsar (J0835−4510) are not well understood. Further insight into these mechanisms can be achieved by long-term studies of integrated pulse width, timing residuals, and bright-pulse rates. We have undertaken an intensive observing campaign of Vela and collected over 6000 hr of single-pulse data. The data shows that the pulse width changes with time, including marked jumps in width after micro-glitches (frequency changes). The abundance of bright pulses also changes after some micro-glitches, but not all. The secular changes in pulse width have three possible cyclic periods that match with X-ray periodicities of a helical jet that are interpreted as free precession.

    Rapid transport current versus high magnetic field characterisation of high-irreversibility type II superconductors is important to maximise their critical parameters. HTS conductors are already used to produce insert coils that increase the fields of conventional magnets made from NbTi (Nb, Ta) 3 Sn and Nb 3 Al wires. There is fundamental interest in the study of HTS tapes and wires in magnetic fields higher than 21T, the current limit of superconducting magnets producing a DC field. Such fields can be obtained by using pulse techniques. High critical currents cannot be routinely measured with a continuous current applied at liquid helium, hydrogen or neon temperatures because of thermal and mechanical effects. A newly developed pulsed magnetic field and pulsed current system which allows rapid J c (B, T) measurements of the whole range of superconducting materials was tested with a multifilamentary NbTi wire in perpendicular and parallel orientations

    Pulsed laser coronary angioplasty with an excimer or a holmium-yttrium-aluminum-garnet (Ho:YAG) laser may become an alternative treatment for patients with coronary artery disease. However, little is known about its acute consequences on the normal arterial wall. This study was designed to examine the acute histologic consequences of these two pulsed lasers on the arterial wall of normal iliac arteries in rabbits. Irradiation with each laser was performed in 15 normal iliac sites on eight male New Zealand white rabbits. The excimer laser was operated at 308 nm, 25 Hz, 50 mJ/mm2/pulse, and 135 nsec/pulse and the Ho:YAG laser was operated at 2.1 micrometers , 3/5 Hz, 400 mJ/pulse, and 250 microsecond(s) ec/pulse. The excimer and Ho:YAG laser were coupled into a multifiber wire-guided catheter of 1.4 and 1.5 mm diameter, respectively. The sites irradiated with excimer or Ho:YAG laser had the same kinds of histologic features, consisting of exfoliation of the endothelium, disorganization of internal elastic lamina, localized necrosis of vascular smooth muscle cells, and fissures in the medial layer. However, the sites irradiated with excimer laser had lower grading scores than those irradiated with Ho:YAG laser (p vascular injury.

    The decay Bs to mu+ mu- is one of the milestones of the flavor program at the LHC. We reappraise its Standard Model prediction. First, by analyzing the theoretical rate in the light of its main parametric dependence, we highlight the importance of a complete evaluation of higher-order electroweak corrections, at present known only in the large-mt limit, and leaving sizable dependence on the definition of electroweak parameters. Using insights from a complete calculation of such corrections for K to pi bar{nu} nu decays, we find a scheme in which NLO electroweak corrections are likely to be negligible. Second, we address the issue of the correspondence between the initial and the final state detected by the experiments, and those used in the theoretical prediction. Particular attention is devoted to the effect of the soft radiation, that has not been discussed for this mode in the previous literature, and that can lead to O(10%) corrections to the decay rate. The "non-radiative" branching ratio (that is equiva...

    The $\\Upsilon(1S)\\mu^+\\mu^-$ invariant-mass distribution is investigated for a possible exotic meson state composed of two $b$ quarks and two $\\overline{b}$ quarks, $X_{b\\overline{b}b\\overline{b}}$. The analysis is based on a data sample of $pp$ collisions recorded with the LHCb detector at centre-of-mass energies $\\sqrt{s} = 7$, 8 and 13$\\rm{TeV}$, corresponding to an integrated luminosity of 6.3 fb$^{-1}$. No significant excess is found, and upper limits are set on the product of the production cross-section and the branching fraction as functions of the mass of the $X_{b\\overline{b}b\\overline{b}}$ state. The limits are set in the fiducial volume where all muons have pseudorapidity in the range $[2.0,5.0]$, and the $X_{b\\overline{b}b\\overline{b}}$ state has rapidity in the range $[2.0,4.5]$ and transverse momentum less than 15 $\\rm{GeV}/c$.

    As one of the principal muon beam line at the J-PARC muon facility (MUSE), we are now constructing a Muon beam line (U-Line), which consists of a large acceptance solenoid made of mineral insulation cables (MIC), a superconducting curved transport solenoid and superconducting axial focusing magnets. There, we can extract 2 Multiplication-Sign 10{sup 8}/s surface muons towards a hot tungsten target. At the U-Line, we are now establishing a new type of muon microscopy; a new technique with use of the intense ultra-slow muon source generated by resonant ionization of thermal Muonium (designated as Mu; consisting of a {mu}{sup + } and an e{sup - }) atoms generated from the surface of the tungsten target. In this contribution, the latest status of the Ultra Slow Muon Microscopy project, fully funded, is reported.

  11. Ultra-short pulse, ultra-high intensity laser improvement techniques for laser-driven quantum beam science

    Recent development activities of the Quantum Beam Research Team in JAEA are reported. The downsized, petawatt and femtosecond pulse laser is described at first. The process of the system development and utilization effort of so-called J-KAREN is explained with its time and space control system. For high contrast, OPCPA (Optical Parametric Chirped Pulse Amplification) preamplifier is adopted by using the titanium-sapphire laser system in which only the seed light pulses can be amplified. In addition, high contrast is obtained by adopting the high energy seed light to the amplifier. The system configuration of J-KAREN laser is illustrated. Typical spectra with and without OPCPA, as well as the spectra with OPCPA adjustment and without one are shown. The result of the recompressed pulses is shown in which the pulse width of 29.5 femtoseconds is close to the theoretical limit. Considering the throughput of the pulse compressor is 64 percent it is possible to generate high power laser beam of about 600 terawatts. In the supplementary budget of 2012, it has been approved to cope with the aging or obsoleteness of the system and at the same time to further sophisticate the laser using system. The upgraded laser system is named as J-KAREN-P in which the repetition rate is improved and another booster amplifier is added to increase the power. The system configuration of J-KAREN-P after the upgrading is illustrated. (S. Funahashi)

    PSR J0922+0638 (B0919+06) shows unexplained anomalous variations in the on-pulse phase, where the pulse appears to episodically move to an earlier longitude for a few tens of rotations before reverting to the usual phase for approximately several hundred to more than a thousand rotations. These events, where the pulse moves in phase by up to 5°, have been previously detected in observations from ˜300 to 2000 MHz. We present simultaneous observations from the Effelsberg 100-m radio telescope at 1350 MHz and the Bornim (Potsdam) station of the LOw Frequency ARray at 150 MHz. Our observations present the first evidence for an absence of the anomalous phase-shifting behaviour at 150 MHz. Instead, the observed intensity at the usual pulse-phase typically decreases, often showing a pseudo-nulling feature corresponding to the times when phase shifts are observed at 1350 MHz. The presence of weak emission at the usual pulse-phase supports the theory that these shifts may result from processes similar to the `profile-absorption' expected to operate for PSR J0814+7429 (B0809+74). A possible mechanism for this could be intrinsic variations of the emission within the pulsar's beam combined with absorption by expanding shells of electrons in the line of sight.

    A search for the decay K/sub S/ to 2 mu has given negative results. The 90% confidence upper limit for the branching ratio of 3.1*10/sup -7/ excludes the models of Christ and Lee, and of Dass and Wolfenstein, designed to explain the K/sub L/ to 2 mu problem. (8 refs).

    In the ongoing quest for novel techniques to obtain ever higher laser powers, plasma amplification has drawn much attention, benefiting from the fact that a plasma can sustain much higher energy densities than a solid state amplifier. As a plasma process, Stimulated Brillouin Backscattering in the strong coupling regime (sc-SBS) can be used to transfer energy from one laser pulse (pump) to another (seed), by a nonlinear ion oscillation forced by the pump laser. Here, we report on experimental results on amplification by sc-SBS using the ARCTURUS Ti:Sapphire multi-beam laser system at the University of Duesseldorf, Germany. Counter-propagating in a supersonic Hydrogen gas jet target, an ultrashort seed pulse with a pulse duration between 30 and 160 fs and an energy between 1 and 12 mJ was amplified by a high-energy pump pulse (1.7 ps, 700 mJ). For some of the measurements, the gas was pre-ionized with a separate laser pulse (780 fs, 460 mJ). Preliminary analysis shows that the amplification was larger for the longer seed pulses, consistent with theoretical predictions.

    The results of characterization experiments carried out on a newly developed dense plasma focus device based intense pulsed neutron source with efficient and compact pulsed power system are reported. Its high current sealed pseudospark switch based low inductance capacitor bank with maximum stored energy of ∼10 kJ is segregated into four modules of ∼2.5 kJ each and it cumulatively delivers peak current in the range of 400 kA–600 kA (corresponding to charging voltage range of 14 kV–18 kV) in a quarter time period of ∼2 μs. The neutron yield performance of this device has been optimized by discretely varying deuterium filling gas pressure in the range of 6 mbar–11 mbar at ∼17 kV/550 kA discharge. At ∼7 kJ/8.5 mbar operation, the average neutron yield has been measured to be in the order of ∼4 × 10{sup 9} neutrons/pulse which is the highest ever reported neutron yield from a plasma focus device with the same stored energy. The average forward to radial anisotropy in neutron yield is found to be ∼2. The entire system is contained on a moveable trolley having dimensions 1.5 m × 1 m × 0.7 m and its operation and control (up to the distance of 25 m) are facilitated through optically isolated handheld remote console. The overall compactness of this system provides minimum proximity to small as well as large samples for irradiation. The major intended application objective of this high neutron yield dense plasma focus device development is to explore the feasibility of active neutron interrogation experiments by utilization of intense pulsed neutron sources.

    Lasers for fusion application represent a special class of short-pulse generators; not only must they generate extremely short temporal pulses of high quality, but they must do this at ultra-high powers and satisfy other stringent requirements by this application. This paper presents the status of the research and development of carbon-dioxide laser systems at the Los Alamos Scientific Laboratory, vis-a-vis the fusion requirements

    This work reports on the Q-switched pulsed laser generation from double-cladding Nd:YAG ceramic waveguides. Double-cladding waveguides with different combination of diameters were inscribed into a sample of Nd:YAG ceramic. With an additional semiconductor saturable absorber, stable pulsed laser emission at the wavelength of 1064 nm was achieved with pulses of 21 ns temporal duration and ~14 μJ pulse energy at a repetition rate of 3.65 MHz.

    The laser-induced phase separation of charcoal particles on additive-free cotton linters cellulose paper was investigated by electron and optical microscopy, colorimetry, and diffuse reflectance FT-IR. The fibre bundles were vaporised in depth of several 10 {mu}m above destruction fluence thresholds using visible 532 nm radiation. This is in contrast to mid-ultraviolet 213 nm radiation, where only the top fibre bundles were modified and partially evaporated. The colorimetric lightness results generally represented the cleaning status, whereas the colorimetric yellowing data represented irreversible chemical and/or photochemical changes. Charcoal-contaminated paper treated with visible and mid-ultraviolet radiation exhibited yellowing, whereas uncontaminated did not. This suggests that the electron-rich plasma generated by the evaporation of the particles heats the adjacent substrate and also excludes oxygen. Mid-ultraviolet, in contrast to visible radiation, shows particle removal always accompanied by paper destruction. IR spectroscopy results suggest cross-linking by ether bonds near the destruction threshold, but do not prove the formation of oxidation products and double bonds as the basis of the yellowing. A ''cleaning window'' between the cleaning threshold (0.1 J/cm{sup 2}) and the paper destruction threshold (2.9 J/cm{sup 2}) with a pulse number of 2 is provided by visible 532 nm laser treatment.
