    The centroid of proton-antiproton physics is moving west across the Atlantic concluded Luigi Di Leila of CERN in his summary talk at the Topical Workshop on Proton-Antiproton Collider Physics, held at Fermilab in June. Previous meetings in this series had been dominated by results from CERN's big proton-antiproton collider, dating back to 1981. However last year saw the first physics run at Fermilab's collider, and although the number of collisions in the big CDF detector was only about one thirtieth of the score so far at CERN, the increased collision energy at Fermilab of 1.8 TeV (1800 GeV, compared to the routine 630 GeV at CERN) is already paying dividends

    1982-01-01

    The 2nd international conference 'Physics in Collision' took place in Stockholm from 2-4 June. Some 160 delegates from all over the world gathered together to learn and to discuss about the most recent results from proton-proton, proton-antiproton and electron-positron colliders. The firsft conference in this series was held in May 1981 in Blacksburg, Virginia, and next year's meeting is scheduled for Lake Como, Italy. Excerpt from the Pope's speech: Let me in conclusion refer to the possible applications of your research even if they are not directly connected with your work, your responsibilities and the purpose of this laboratory. History has shown that the discovery of new phenomena leads in time to wondrous applications that are often completely unexpected. Your Member States and their governments and technicians already no doubt follow your research with an interest that is all the greater because they anticipate exploiting them intensively sooner or later. What applications can be expected to stem from the knowledge the structure of the atom and the possibility of its decomposition? Men may use their knowledge for better or for worse. The best use will be to serve mankind and its development, in the fields of health care, food resources, sources of energy and protection of the environment. The worst use would be the destruction of the ecological balance, the creation of dangerous levels of radioactivity and, worst of all, the production of instruments of destruction which in power and quantity are already exceedingly dangerous. We are faced with a great moral challenge — we must harmonize the forces of technology, born from science, with the forces of conscience. 'Conscience must be mobilized! ' The cause of mankind will be served if science and conscience go hand in hand. In other words, great attention must be paid to how man uses these discoveries, and his motivation when making the choice

    Fraser, Gordon Murray

    1997-01-01

    This end-of-term seminar looks at science behind the scenes. While physicists study the forces at work in Nature, physical force - the exercise of power - drives history. As well as diligent investigation, the focus and progress of science are also strongly influenced by contemporary issues. The search for new applications, the availability of new technology, the cult of personality, political upheaval and war, large-scale investment, and communications barriers have all played major roles.

    International Nuclear Information System (INIS)

    Wiel, M.J. van der.

    1975-01-01

    The relation between photo absorption and electron scattering as tools in atom and molecular physics is described. The advantages and disadvantages of both methods are compared, and an account of their theoretical background is given. The emphasis is on the continuous part of the photo absorption spectrum because it contains the greater part of the excitation probability. In addition it is argued that the strength of the electron-method lies in the measurement of large energy ranges with a constant efficiency and modest resolution power. The possible use of synchrotron radiation is discussed

  19. Physics of Nuclear Collisions at High Energy

    Energy Technology Data Exchange (ETDEWEB)

    Hwa, Rudolph C. [Univ. of Oregon, Eugene, OR (United States)

    2012-05-01

    A wide range of problems has been investigated in the research program during the period of this grant. Although the major effort has been in the subject of heavy-ion collisions, we have also studied problems in biological and other physical systems. The method of analysis used in reducing complex data in multiparticle production to simple descriptions can also be applied to the study of complex systems of very different nature. Phase transition is an important phenomenon in many areas of physics, and for heavy-ion collisions we study the fluctuations of multiplicities at the critical point. Human brain activities as revealed in EEG also involve fluctuations in time series, and we have found that our experience enables us to find the appropriate quantification of the fluctuations in ways that can differentiate stroke and normal subjects. The main topic that characterizes the research at Oregon in heavy-ion collisions is the recombination model for the treatment of the hadronization process. We have avoided the hydrodynamical model partly because there is already a large community engaged in it, but more significantly we have found the assumption of rapid thermalization unconvincing. Recent results in studying LHC physics lead us to provide more evidence that shower partons are very important even at low p_T, but are ignored by hydro. It is not easy to work in an environment where the conventional wisdom regards our approach as being incorrect because it does not adhere to the standard paradigm. But that is just what a vibrant research community needs: unconventional approach may find evidences that can challenge the orthodoxy. An example is the usual belief that elliptic flow in fluid dynamics gives rise to azimuthal anisotropy. We claim that it is only sufficient but not necessary. With more data from LHC and more independent thinkers working on the subject what is sufficient as a theory may turn out to be incorrect in reality. Another area of investigation that

    Colla, M.; Gulley, R.; Uhlmann, L.; Hoogerland, M.D.; Baldwin, K.G.H.; Buckman, S.J.

    1999-01-01

    Full text: Metastable helium in the 2 3 S state is an important species for atom optics and atomic collision physics. Because of its large internal energy (20eV), long lifetime (∼8000s) and large collision cross section for a range of processes, metastable helium plays an important role in atmospheric physics, plasma discharges and gas laser physics. We have embarked on a program of studies on atom-atom and electron-atom collision processes involving cold metastable helium. We confine metastable helium atoms in a magneto-optic trap (MOT), which is loaded by a transversely collimated, slowed and 2-D focussed atomic beam. We employ diode laser tuned to the 1083 nm (2 3 S 1 - 2 3 P2 1 ) transition to generate laser cooling forces in both the loading beam and the trap. Approximately 10 million helium atoms are trapped at temperatures of ∼ 1mK. We use phase modulation spectroscopy to measure the trapped atomic density. The cold, trapped atoms can collide to produce either atomic He + or molecular He 2 + ions by Penning Ionisation (PI) or Associative Ionisation (AI). The rate of formation of these ions is dependant upon the detuning of the trapping laser from resonance. A further laser can be used to connect the 2 3 S 1 state to another higher lying excited state, and variation of the probe laser detuning used to measure interatomic collision potential. Electron-atom collision processes are studied using a monochromatic electron beam with a well defined spatial current distribution. The total trap loss due to electron collisions is measured as a function of electron energy. Results will be presented for these atomic collision physics measurements involving cold, trapped metastable helium atoms. Copyright (1999) Australian Optical Society

    1985-09-01

    The research program concentrates on correlation studies in central collisions. The investigation includes: multi-pion production, total event structure, application of the Vlasov-Uehling-Uhlenbeck model (VUU) to the data and energy dependence of thermalization and nuclear stopping power. The initial analysis on the Uranium-Uranium exposure at 960 MeV/nucleon is completed. In place of the conventional sphericity analysis, global transverse momentum as a function of rapidity and azimuthal angle is a more appropriate parameter for these data in the total event analysis. This transverse momentum analysis is extended to other projectile/target systems with initial results for Ar on KCl, BaI 2 , Pb, and U on U. In the area of pion production, results for Kr on RbBr at the Darmstadt Heavy Ion Study are reported. Early findings that the source size is related to the emitted pion momentum is confirmed. 17 refs

    2015-12-01

    Full Text Available In this paper the key concepts of ITS - Intelligent Transport Systems, CPS - Cyber-Physical Systems and SM - Smart Mobility are defined and correlated with the need for ACAS – Airborne Collision Avoidance System, as the last resort safety net and indispensable ingredient in civil aviation. Smart Mobility is addressed from a Cyber Physical-Systems perspective, detailing some of the elements that this entails. Here we consider the Air Transportations System of the future as a Cyber-Physical System and analyze the implications of doing so from different perspectives. The objective is to introduce a 4D collision avoidance shield technology which forms a last resort safety net technology for the next generation air transport (2050 and beyond. The new system will represent a step change over the performance of current technology. As conclusions, the benefits of implementing Transport Cyber-Physical Systems are discussed, as well as what this would require for future deployment.

    The activities of the plasma physics section of the Bhabha Atomic Research Centre, India over the last five years (1970-75) are reported. The R and D programme of the section has been divided into four cells mainly i.e., (i) Thermal plasma (ii) Relativistic Electron Beam (iii) Energetics and (iv) Electron beam technology. The salient features of the development activities carried out in these cells are outlined. In the Thermal plasma group, considerable research work has been done in (a) fundamental plasma studies, (b) industrial plasma technology and (c) open cycle MHD power generation project. The relativistic electron beam group is engaged in improving the technology to realize high power lasers, and pulsed thermonuclear fusion. The energetics programme is oriented to develop high voltage d.c. generators and pulse generators. The electron beam techniques developed here are routinely used for melting refractory and reactive metals. The technical know-how of the welding machines developed has been transfered to industries. Equipment developed by this section, such as, (1) electron beam furnace, (2) plasma cutting torch, (3) impulse magnet charger etc. are listed. (A.K.)

    1986-05-01

    This report summarizes the work of the Accelerator Physics Section of the Institute of Nuclear Sciences during the period January-December 1985. Applications of the EN-tandem accelerator included 13 N production for tracer experiments in plants and animals, hydrogen profiling with a 19 F beam and direct detection of heavy ions with a surface barrier detector. Preparations for accelerator mass spectrometry continued steadily, with the commissioning of the pulsed EHT supply which selects the isotope to be accelerated, routine detection of 14 C ions, and completion of a sputter ion source with an eight position target wheel. It was shown that the hydrogen content of a material could be derived from a simultaneous measurement of the transmission of neutrons and gamma rays from a neutron source or accelerator target. The 11 CO 2 produced at the 3 MV accelerator was used in two studies of translocation in a large number of plant species: the effects of small quantities of SO 2 in the air, and the effect of cooling a short length of the stem. The nuclear microprobe was applied to studies of carbon pickup during welding of stainless steel, determination of trace elements in soil and vegetation and the measurement of sodium depth profiles in obsidian - in particular the effect of rastering the incident proton beams

    The theoretical atomic and molecular physics program at Rice University emphasizes fundamental questions regarding the structure and collision dynamics of various atomic and molecular systems with some attention given to atomic processes at surfaces. Our activities have been centered on continuing the projects initiated last year as well as beginning some new studies. These include: differential elastic and charge-transfer scattering and alignment and orientation of the excited electron cloud in ion-atom, atom-atom and ion-molecule collisions, using a molecular-orbital representation and both semiclassical and quantal methods; quenching of low-lying Rydberg states of a sodium atom in a collision with a rare-gas atom, using a semiclassical representation; so far, target atoms He, Ne and Ar have been studied; chemiionization and ion-pair formation in a collision of a Li atom with a metastable He atom at intermediate collision energies, using a combination of quantal and semi-classical methods; Penning ionization of alkali atoms Na and K, using advanced Cl and Stieltjes imaging methods; radiative and nonradiative charge-transfer in He + + H collisions at ultra-low collision energies, using quantal methods; elastic and inelastic processes in electron-molecule collisions, using the continuum-multiple-scattering method; and inelastic collision processes in dense, high-temperature plasmas. Selected highlights of our research progress are briefly summarized in this paper

    Accelerators have been shown to have great utility in addressing a broad range of problems in experimental atomic physics. There are, of course, phenomena such as inner-shell MO promotion which can occur only at high collision energies. At much higher energies, large transient Coulomb fields can be generated which lead to copious production electron-positron pairs and to capture of electrons from the negative continuum. But in addition, many advantages can be gained by carrying out low-energy (center-of-mass) collisions at high laboratory energies, specifically in a single pass mode or in multi-pass modes in ion storage rings in which, e.g., collision in the milli-electron volt region can be achieved for electron-molecule reactions. Certain advantages also accrue using open-quotes reverse kinematicsclose quotes in which high velocity ions collide with almost open-quotes stationaryclose quotes electrons as in resonant transfer and excitation (RTE) and collisions of energetic ions in the dense open-quotes electron gasclose quotes found in crystal channels

  14. Heavy quark physics in ep collisions at LEP+LHC

    Ali, A.; Barreiro, F.; Troconiz, J.F. de; Schuler, G.A.; Bij, J.J. van der

    We study electroweak production of heavy quarks - charm, beauty, and top - in deep inelastic electron-proton collisions at the proposed LEP+LHC collider at CERN. The assumed energy for the collisions is E e =50 GeV, E p =8000 GeV, providing an ep center of mass energy, √s≅1.26 TeV. We invoke the boson-gluon fusion model to estimate theoretical cross sections and distributions for the heavy quarks. Higher order QCD corrections are only approximately taken into account, by assuming a (normalization) K-factor of 2 for the charm and beauty quark production rates and incorporating the parton shower cascades. With these assumptions and the parameterization of Eichten et al. for the structure functions (EHLQ, set 1), we find the following cross sections: σ(ep→c+X)≅O(3 μb), σ(ep→b+X)≅O(40 nb), and σ(ep→t+X)≅4 pb for m t =120 GeV, decreasing to 0.5 pb for m t =250 GeV. These cross sections would provide O(6x10 9 ) charmed hadrons, O(8x10 7 ) beauty hadrons, and O(10 3 ) top hadrons, for an integrated ep luminosity of 1000 pb -1 . The heavy quark rates in ep collisions are considerably smaller than the corresponding rates in pp collisions at LHC, with √s=16 TeV. This gives a clear advantage to pp collisions for top searches. However, for the charmed and beauty quarks only a tiny fraction of the cross sections in p+p→Q+X can be triggered in comparison to the corresponding cross sections in e+p→Q+X, resulting in comparable number of measured heavy quark events in the ep and pp mode. We sketch the energy-momentum profile of heavy quark events in ep collisions and illustrate the kind of analyses that experiments at the LEP+LHC collider would undertake to quantitatively study heavy quark physics. In particular, prospects of measuring the particle-antiparticle mixing parameter x s =ΔM/Γ for the B s 0 -anti B s 0 meson system are evaluated, and search strategies for the top quark in ep collisions are presented.

    1994-08-01

    The study of inelastic collision phenomena with highly charged projectile ions and the interpretation of spectral features resulting from these collisions remain as the major focal points in the atomic physics research at the J.R. Macdonald Laboratory, Kansas State University, Manhattan, Kansas. The title of the research project, ``Atomic Physics with Highly Charged Ions,`` speaks to these points. The experimental work in the past few years has divided into collisions at high velocity using the primary beams from the tandem and LINAC accelerators and collisions at low velocity using the CRYEBIS facility. Theoretical calculations have been performed to accurately describe inelastic scattering processes of the one-electron and many-electron type, and to accurately predict atomic transition energies and intensities for x rays and Auger electrons. Brief research summaries are given for the following: (1) electron production in ion-atom collisions; (2) role of electron-electron interactions in two-electron processes; (3) multi-electron processes; (4) collisions with excited, aligned, Rydberg targets; (5) ion-ion collisions; (6) ion-molecule collisions; (7) ion-atom collision theory; and (8) ion-surface interactions.

    The application of relativistic continuum physics to the description of the nuclear fireball evolution from the start of expansion to the breaking is discussed. The basic formalism and basic assumptions of relativistic hydrodynamics and thermodynamics are analyzed in detail. The four basic assumptions are not valid in the case of nuclear fireball produced in heavy ion collisions, but thermodynamics can be extended in different ways to incorporate anisotropy, fluctuations, gradients and the lack of the local equilibrium. The extended continuum formalism is applicable to the description of the nuclear fireball dynamics, including the nuclear - quark matter phase transition. (D.Gy.)

    1988-08-01

    In April 1988 we, along with the nuclear theory groups of Brookhaven and MIT, submitted a proposal to the Department of Energy for a national Institute of Theoretical Nuclear Physics. The primary areas of investigation proposed for this Institute are: Strong Interaction Physics--including (1) The physics of hadrons, (2) QCD and the nucleus, (3) QCD at finite temperatures and high density; nuclear astrophysics; nuclear structure and nuclear many-body theory; and nuclear tests of fundamental interactions. It is, of course, no coincidence that these are the main areas of activity of the three groups involved in this proposal and of our group in particular. Here, we will organize an outline of the progress made at Stony Brook during the past year along these lines. These four areas do not cover all of the activities of our group

    The present study shows a progressive increase in the number of female physicists as undergraduates and postgraduates in several governmental universities. For instance, in Ain Shams University, the percentage of women who selected physics as a major course of study increased from 7.2% in 2012 to 10.8% in 2013 and 15.7% in 2014. The study also provides the current gender distribution in the various positions among the teaching staff in seven governmental universities. The data supports the fact that female teaching assistants are increasing in these universities.

    somehow biased toward personal conclusion drawn during the course of the thesis work. Chapter 3 give a brief introduction to some theoretical approaches of high-energy hadronic scattering, both in the soft and hard regime. Also, the Glauber model is briefly described. Nuclear effects in hadron-nucleus collisions are introduced in Chapter 4 with a main emphasis on nuclear shadowing. Other multiple scattering effects, such as absorption and transverse momentum broadening, are briefly described. We present also some preliminary result on particle production in p+Pb and d+Au collisions at SPS and RHIC, respectively. Finally, nucleus-nucleus collisions are discussed in Chapter 5 in the context of simple model of final state interactions. In the 'string' jargon one may say, that the former chapter relates to particle production from independent strings, while the latter additionally includes the possibility of string interaction or, rather, interactions of particles originating from different strings. Chapter 6 contains a description of the main results obtained in the papers, and outlines interesting topics for further study in the LHC-era of heavy-ion physics.(Author). refs., figs., tabs

    The tagged-photon beam effort consists of Fermilab experiments E516 (photoproduction) and E691 (charm photoproduction). Most of the work of this period was devoted to bringing E691 into operation and collecting data. Progress in the Fermilab broad-band neutral beam program included setting up the production data analysis for E400 (hadronic charm production), and design, prototyping, procurement and fabrication of the electromagnetic calorimeter for E687 (photoproduction at the Tevatron). The electron-positron effort at SLAC included data-taking and physics analysis with MAC, fabrication of a trigger/vertex drift chamber for the Mark II upgrade, and prototype studies for SLD. The theory group carried out a broad program of research in many branches of particle physics. Studies included formal work in supergravity, supersymmetry phenomenology, lattice gauge theory approaches to hadronization, investigations of the behavior of the quark-gluon plasma in the early Universe, in heavy ion collisions, and on the lattice, and a first look at the real-time behavior of quantum systems out of thermal equilibrium. A program in laboratory-based gravity research came under the support of this contract as of April 1, 1985. The principal effort is a test of the equivalence of inertial and passive gravitational mass (Eotvos experiment) of high sensitivity in a cryogenic system

    International Nuclear Information System (INIS)

    Malhotra, Shivali

    2013-01-01

    The model-independent analysis systematically scans the data taken by Compact Muon Solenoid - CMS detector for deviations from the Standard Model (SM) predictions. This approach is sensitive to a variety of models for new physics due to the minimal theoretical bias i.e. without assumptions on specific models of new physics and covering a large phase space. Possible causes of the significant deviations could be insufficient understanding of the collision event generation or detector simulation, or indeed genuine new physics in the data. Thus the output of MUSiC must be seen as only the first, but important step in the potential discovery of new physics. To get the distinctive final states, events with at least one electron or muon are classified according to their content of reconstructed objects (muons, electrons, photons, jets and missing transverse energy) and sorted into event classes. A broad scan of three kinematic distributions (scalar sum of the transverse momentum, invariant mass of reconstructed objects and missing transverse energy) in those event classes is performed by identifying deviations from SM expectations, accounting for systematic uncertainties. A scanning algorithm determines the regions in the considered distributions where the measured data deviates most from the SM predictions. This search is sensitive to an excess as well as a deficit in the comparison of data and SM background. This approach has been applied to the CMS data and we have obtained the preliminary results. I will talk about the details of the analysis techniques, its implementation in analyzing CMS data, results obtained and the discussion on the discrepancy observed

  10. Experimental progress in positronium laser physics

    Science.gov (United States)

    Cassidy, David B.

    2018-03-01

    The field of experimental positronium physics has advanced significantly in the last few decades, with new areas of research driven by the development of techniques for trapping and manipulating positrons using Surko-type buffer gas traps. Large numbers of positrons (typically ≥106) accumulated in such a device may be ejected all at once, so as to generate an intense pulse. Standard bunching techniques can produce pulses with ns (mm) temporal (spatial) beam profiles. These pulses can be converted into a dilute Ps gas in vacuum with densities on the order of 107 cm-3 which can be probed by standard ns pulsed laser systems. This allows for the efficient production of excited Ps states, including long-lived Rydberg states, which in turn facilitates numerous experimental programs, such as precision optical and microwave spectroscopy of Ps, the application of Stark deceleration methods to guide, decelerate and focus Rydberg Ps beams, and studies of the interactions of such beams with other atomic and molecular species. These methods are also applicable to antihydrogen production and spectroscopic studies of energy levels and resonances in positronium ions and molecules. A summary of recent progress in this area will be given, with the objective of providing an overview of the field as it currently exists, and a brief discussion of some future directions.

    We discuss the physics of large impact parameter interactions at the LHC: ultraperipheral collisions (UPCs). The dominant processes in UPCs are photon-nucleon (nucleus) interactions. The current LHC detector configurations can explore small $x$ hard phenomena with nuclei and nucleons at photon-nucleon center-of-mass energies above 1 TeV, extending the $x$ range of HERA by a factor of ten. In particular, it will be possible to probe diffractive and inclusive parton densities in nuclei using several processes. The interaction of small dipoles with protons and nuclei can be investigated in elastic and quasi-elastic $J/\\psi$ and $\\Upsilon$ production as well as in high $t$ $\\rho^0$ production accompanied by a rapidity gap. Several of these phenomena provide clean signatures of the onset of the new high gluon density QCD regime. The LHC is in the kinematic range where nonlinear effects are several times larger than at HERA. Two-photon processes in UPCs are also studied. In addition, while UPCs play a role in limit...

We also review similar studies at HERA and RHIC as well as describe the potential use of the LHC detectors for UPC measurements

  16. Quantifying the physical demands of collision sports: does microsensor technology measure what it claims to measure?

    Gabbett, Tim J

    2013-08-01

    The physical demands of rugby league, rugby union, and American football are significantly increased through the large number of collisions players are required to perform during match play. Because of the labor-intensive nature of coding collisions from video recordings, manufacturers of wearable microsensor (e.g., global positioning system [GPS]) units have refined the technology to automatically detect collisions, with several sport scientists attempting to use these microsensors to quantify the physical demands of collision sports. However, a question remains over the validity of these microtechnology units to quantify the contact demands of collision sports. Indeed, recent evidence has shown significant differences in the number of "impacts" recorded by microtechnology units (GPSports) and the actual number of collisions coded from video. However, a separate study investigated the validity of a different microtechnology unit (minimaxX; Catapult Sports) that included GPS and triaxial accelerometers, and also a gyroscope and magnetometer, to quantify collisions. Collisions detected by the minimaxX unit were compared with video-based coding of the actual events. No significant differences were detected in the number of mild, moderate, and heavy collisions detected via the minimaxX units and those coded from video recordings of the actual event. Furthermore, a strong correlation (r = 0.96, p sports. Until such validation research is completed, sport scientists should be circumspect of the ability of other units to perform similar functions.

How can these observables be measured, to what extent can they be calculated, and what do they tell us about the dense mesoscopic system created during the collision? In the first lecture, I shall focus in particular on measurements that constrain the spatio-temporal picture of the collisions and that measure centrality, orientations and extensions. In the subsequent lectures, I then discuss on how classes of measurements allow one to characterize collective phenomena, and to what extent these measurements can constrain the properties of matter produced in heavy ion collisions.

    SuperB is a high luminosity e+e- collider that will be able to indirectly probe new physics at energy scales far beyond the reach of any man made accelerator planned or in existence. Just as detailed understanding of the Standard Model of particle physics was developed from stringent constraints imposed by flavour changing processes between quarks, the detailed structure of any new physics is severely constrained by flavour processes. In order to elucidate this structure it is necessary to perform a number of complementary studies of a set of golden channels. With these measurements in hand, the pattern of deviations from the Standard Model behavior can be used as a test of the structure of new physics. If new physics is found at the LHC, then the many golden measurements from SuperB will help decode the subtle nature of the new physics.

    CERN Document Server

    1984-01-01

    Scattering phenomena play an important role in modern physics. Many significant discoveries have been made through collision experiments. Amongst diverse kinds of collision systems, this book sheds light on the collision of an electron with a molecule. The electron-molecule collision provides a basic scattering problem. It is scattering by a nonspherical, multicentered composite particle with its centers having degrees of freedom of motion. The molecule can even disintegrate, Le., dissociate or ionize into fragments, some or all of which may also be molecules. Although it is a difficult problem, the recent theoretical, experimental, and computational progress has been so significant as to warrant publication of a book that specializes in this field. The progress owes partly to technical develop­ ments in measurements and computations. No less important has been the great and continuing stimulus from such fields of application as astrophysics, the physics of the earth's upper atmosphere, laser physics, radiat...

    A physical meaning of the outcomes from hadronic and nuclear collision processes at high energies is presented, as prompted experimentally. The fast and slow stages in hadron-nucleus collisions are distinguished. Hadrons are produced via intermediate objects observed in hadron-nucleus collisions. The intermediate objects may be treated as the groups of quarks or the quark bags. 37 refs

    Cross sections for rotational and vibrational excitations of H{sub 2} molecules caused by impact of electron, proton, H atom, H{sub 2}, H{sub 2}{sup +}, or H{sup -} are compared with one another and reviewed for rotational excitations by examining an interaction potential between collision partners. It is pointed out what are difficulties in theoretical approaches to collision of atoms with H{sub 2} molecules initially in vibrationally and rotationally excited states. A theoretical approach developed by our group, which aims quantum mechanically to investigate vibrationally inelastic scattering, exchange reaction, or dissociation of molecule in vibrationally excited states collided with an atom or its ion, is presented. Newly obtained dissociation cross sections of H{sub 2} in vibrationally excited states by He impact are presented and compared in magnitude with those of H{sub 2} caused by electron impact. (author)

    2014-12-01

    Full Text Available The creation of electron-positron pairs from the vacuum by strong electromagnetic fields is a fundamental and one of the most fascinating processes of relativistic quantum mechanics. Fields sufficiently strong to induce pair creation can be produced, for example, in collisions of bare ions. The process has been studied intensively both in theory and experiment since the 1980s. In peripheral relativistic heavy-ion collisions electromagnetic fields are very strong and interact with each other for a very short time. In these strong fields, probabilities of various electromagnetic processes such as free pair production, bound-free pair production and excitation are large and increase with the Lorentz factor γ. Measurement of cross sections and other relevant distributions are very important for understanding the strong field effect.

    This report outlines the 1998 research activities carried out by the Applied Physics Division of the Innovation Department of ENEA (Italian Agency for New Technologies, Energy and Environment). The fields addressed and discussed include: optical and electro-optical technologies (chaps. 1 and 2); accelerator technologies (chap. 3); diagnostic systems for science and engineering (chaps. 4 and 5); theory, modelling and computational methods (chaps. 6 and 7). The aim of the Applied Physics Division is to develop technologies and systems that can be directly applied by internal (ENEA) and external users in research (high-resolution spectroscopy, laser-generated soft-x-ray sources), production processes (laser material photoproduction, structural analysis), social, cultural and environmental sciences (laser remote sensing, modelling of ecosystems and population dynamics) and medicine (particle accelerator for radiotherapy). Most of the work in 1998 was performed by the division's laboratories at the Frascati, Casaccia and Bologna Research Centres of ENEA; some was done elsewhere in collaboration with other ENEA units, external laboratories and industries. A good share of the activities was carried out for international projects; in particular, the IV European Union Framework Program.

  9. Plasma physics group progress report for 1976

    International Nuclear Information System (INIS)

    1977-01-01

    Progress is reported on the continuing experimental programme on the Lt-3 tokamak, the completion of the new LT-4 tokamak and newly developed diagnostic techniques. Experimental work on LT-3 was generally aimed at invest-igating aspects of the disruptive instability. Magnetic probe measurements were made to obtain radial profiles of the toroidal electric field and an electrostatic probe was used to identify high frequency fluctuations in the plasma at the time of the disruption. Further measurements were also made of local variations in the poloidal magnetic field due to the development of tearing MHD modes. Some preliminary work was done in an investigation of the development of the plasma current profile as operating parameters were varied. During the initial operation of LT-4 (I) diagnostics were limited to standard electrical measurements, spectroscopic and magnetic field observations. Thomson scattering measurements are included in the longer term programme and a ruby laser system has been ordered. New diagnostic techniques used with LT-3 include a variation of the swept Langmuir probe and a method for abelisation of spectroscopic observations in toroidal geometry. (J.R.)

  13. Health physics instrumentation - a progress report

    International Nuclear Information System (INIS)

    Maushart, R.

    1992-01-01

    Health Physics Instruments have changed rather dramatically in the past decade. On the one hand, technological innovations like Microprocessors, data storage facilities and imaging displays have altered shape, size and appearance of the classical devices, particularly the hand-held ones. On the other hand, instruments are increasingly being considered as an integral part of Radiation Protection procedures and organizations, supporting a smooth and reliable implementation of all necessary measures. This implies ease of operation, and extensive self-checking and performance control features. Since there are different categories of users with quite different degrees of motivation and training, the measuring instruments of the future will have to be adapted to specific types of users. Instruments for 'professional' radiation protection - for example in nuclear power plants and nuclear technology - will differ from instruments used in the radionuclide laboratory, where radiation protection will necessarily have to be done as a 'side-job'.

    Bazilevsky, A.; Bland, L.; Vogelsang, W.

    2010-03-17

    This volume archives the presentations at the RIKEN BNL Research Center workshop 'Progress in High-PT Physics at RHIC', held at BNL in March 2010. Much has been learned from high-p{sub T} physics after 10 years of RHIC operations for heavy-ion collisions, polarized proton collisions and d+Au collisions. The workshop focused on recent progress in these areas by both theory and experiment. The first morning saw review talks on the theory of RHIC high-p{sub T} physics by G. Sterman and J. Soffer, and on the experimental results by M. Tannenbaum. One of the most exciting recent results from the RHIC spin program is the first observation of W bosons and their associated single-spin asymmetry. The new preliminary data were reported on the first day of our workshop, along with a theoretical perspective. There also were detailed discussions on the global analysis of polarized parton distributions, including the knowledge on gluon polarization and the impact of the W-data. The main topic of the second workshop day were single-transverse spin asymmetries and their analysis in terms of transverse-momentum dependent parton distributions. There is currently much interest in a future Drell-Yan program at RHIC, thanks to the exciting physics opportunities this would offer. This was addressed in some of the talks. There also were presentations on the latest results on transverse-spin physics from HERMES and BELLE. On the final day of the workshop, the focus shifted toward forward and small-x physics at RHIC, which has become a cornerstone of the whole RHIC program. Exciting new data were presented and discussed in terms of their possible implications for our understanding of strong color-field phenomena in QCD. In the afternoon, there were discussions of nuclear parton distributions and jet observables, among them fragmentation. The workshop was concluded with outlooks toward the near-term (LHC, JLab) and longer-term (EIC) future. The workshop has been a great success

  7. Problems and progress in radiation physics of semiconductors

    International Nuclear Information System (INIS)

    Vinetskij, V.L.

    1982-01-01

    A survey of the current status of radiation physics of semiconductors comprises the analysis of some new problems and poses the statement of concern. The essential difference between the probability of interstitial-vacancy pair occurrence W(T) in elastic collisions and the generally accepted step distribution with a typical ''threshold'' energy Tsub(d) is indicated. The role of diffusion and reaction evolution of primary defects leading to specific properties of the cluster formation process is shown. Special features of defect formation in spatially inhomogeneous semiconductors, in particular for elastic stresses present, are described. Among most important advances in the radiation physics of semiconductors there are the discovery of non-activation motion of the ''extra'' atom in silicon, the observation of a low activation energy value for the vacancy diffusion, the understanding of subthreshold mechanism of defect formation and radiation-induced diffusion, the effects of laser annealing of defects and oriented crystallization

  9. Pion correlations and calorimeter design for high energy heavy ion collisions. Progress report

    International Nuclear Information System (INIS)

    Wolf, K.L.

    1997-01-01

    Data analysis is in progress for recent experiments performed by the NA44 collaboration with the first running of 160 A GeV 208 Pb-induced reactions at the CERN SPS. Identified singles spectra were taken for pions, kaons, protons, deuterons, antiprotons and antideuterons. Two-pion interferometry measurements were made for semi-central-triggered 208 Pb + Pb collisions. An updated multi-particle spectrometer allows high statistics data sets of identified particles to be collected near mid-rapidity. A second series of experiments will be performed in the fall of 1995 with more emphasis on identical kaon interferometry and on the measurement of rare particle spectra and correlations. Modest instrumentation upgrades by TAMU are designed to increase the trigger function for better impact parameter selection and improved collection efficiency of valid events. An effort to achieve the highest degree of projectile-target stopping is outlined and it is argued that an excitation function on the SPS is needed to better understand reaction mechanisms. Analysis of experimental results is in the final stages at LBL in the EOS collaboration for two-pion interferometry in the 1.2 A GeV Au + Au reaction, taken with full event characterization

    CERN. Geneva

    2004-01-01

    The BaBar experiment at SLAC studies B-physics at the Upsilon(4S) resonance using the high-luminosity e+e- collider PEP-II at the Stanford Linear Accelerator Center (SLAC). Taking, processing and analyzing the very large data samples is a significant computing challenge. This presentation will describe the entire BaBar computing chain and illustrate the solutions chosen as well as their evolution with the ever higher luminosity being delivered by PEP-II. This will include data acquisition and software triggering in a high availability, low-deadtime online environment, a prompt, automated calibration pass through the data SLAC and then the full reconstruction of the data that takes place at INFN-Padova within 24 hours. Monte Carlo production takes place in a highly automated fashion in 25+ sites. The resulting real and simulated data is distributed and made available at SLAC and other computing centers. For analysis a much more sophisticated skimming pass has been introduced in the past year, ...

  13. EDITORIAL: 'Key issues' articles in Reports on Progress in Physics

    Science.gov (United States)

    Greene, Laura H.

    2007-03-01

    The Editorial Board of Reports on Progress in Physics has commissioned a series of short articles from world leaders on key physics issues in their field. These essays may raise the key issues, or ask open questions or may even suggest wild ideas. Basically, they give world leading physicists the opportunity to write what they think about the key issues in their field, free from the usual requirement to provide the fair and balanced presentations of the subject normally found in articles in Reports on Progress in Physics. We believe that the readers of the journal will be interested to learn about these exciting ideas. Just as Hilbert's famous paper of 1900 set the agenda for the next century or more in mathematics, so we hope that this series of papers will define the key issues and open questions in physics for the 21st Century and that the articles will be widely cited and downloaded. The first of these articles—'Insights from simulations of star formation' by Richard B Larson (Yale University, USA)—is published in the current issue. We trust that readers will find this article and its successors in the series to appear through 2007 and beyond entertaining and stimulating.

  15. Search for New Physics Using Jets in Proton-Proton Collisions

    CERN Document Server

    AUTHOR|(INSPIRE)INSPIRE-00338702

    In this thesis a search for New Physics in events with two jets is presented. These events are produced in proton-proton collisions at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) close to the lake Geneva in Switzerland. These collisions have been recorded with the ATLAS experiment, a large multi-purpose particle detector that is placed at one of four points in the LHC where the proton beams are brought to collision. The theory to describe the processes of particle physics, the Standard Model, was able to describe all measurements made so far. Apart from this amazing agreement, the Standard Model does not give an answer to some fundamental questions. How can gravity be described within the Standard Model? What is the mysterious form of matter that has not been seen, but 26 % of the universe are made of? Why are neutrinos massive? Models answering some of these questions lead to the prediction of additional particles, that have not be seen before. A search for new p...

    Research in the Physics Department covers two main fields: condensed matter physics and plasma physics. The principal activites in these fields are presented in this Progress Report covering the period from 1 January to 31 December 1989. The condensed matter physics research is predominantly experimental utilising diffraction of neutrons and x-rays. The research topics range from studies of two- and three-dimensional structures, magnetic ordering, heavy fermions, phase transitions in model systems to studies of texture and recrystallization kinetics with a more applied nature. The discovery of the high Tc superconductors in 1986 has opened an important new research area, where neutron and x-ray diffraction are used to elucidate the basic mechanism responsible for the superconductivity and in the analysis of the solid state syntheses used in producing the materials. The plasma physics research is partly experimental and partly theoretical. The plasma physics programme is also of a wide scope ranging from fundamental studies of wave propagation, instabilities, solitons and turbulence in plasmas to refuelling a fusion reactor by deuterium-tritium pellets.

  17. Physics Department annual progress report 1 January - 31 December 1982

    International Nuclear Information System (INIS)

    1983-09-01

    Research in the Physics Department at Risoe National Laboratory covers three main fields: condensed matter physics, plasma physics and meteorology. The report is a progress report describing the principal activities in these fields for the period from 1 January to 31 December 1982. The condensed matter physics research is predominantly experimental utilising diffraction of neutrons, X-rays, and synchrotron X-ray radiation. The research topics range from studies of structure, excitations and phase transitions in model systems to studies of ion transport, texture and recrystallization kinetics with a more applied nature. The plasma physics research is partly experimental and partly theoretical. A study of pellet-plasma interaction is of applied nature and aimed at assessing the possibilities of refuelling a fusion reactor by shooting deuterium-tritium pellets into the plasma. A study of the fundamental physics of plasmas deals with investigations of wave propagation properties, instabilities, solitons, turbulence, etc. The research and applied work within meteorology lies within micrometereology and the subjects range from surface energy balance studies, over studies of the general structure of atmospheric coherence and boundary layer response to change in surface elevation, to specific studies of turbulent dispersion and deposition of airborne material. As part of the applied work within meteorology and wind energy, the test station for small windmills tests and licences windmills for the Danish market and offers consulting assistance for the Danish windmill manufacturers.

  19. Learning to cooperate is essential for progress in physics

    Science.gov (United States)

    Dickau, Jonathan J.

    2012-06-01

    At the 10th Frontiers of Fundamental Physics symposium, Gerard't Hooft stated that, for some of the advances we hope to see in Physics during the future, there must be a great deal of cooperation between physicists from different disciplines, as well as mathematicians, programmers, technologists, and others. This requires us to evolve a new mindset; however, as so much of our past progress has come out of a fiercely competitive process - especially since a critical review of our ideas about reality remains essential to making clear progress and checking our progress. We must also address the fact that some frameworks appear incompatible, as with relativity and quantum mechanics, whose unification remains distant despite years of attempts to find a quantum gravity theory. I explore the idea that playful exploration, using both left-brained and right-brained approaches to learning, allows us to resolve conflicting ideas by taking advantage of innate human developmental and learning strategies and brain structure. It may thus foster the kind of interdisciplinary cooperation we are hoping to see.

    Bernstein, E.M.; Tanis, J.A.

    1986-04-01

    X-ray emission associated with projectile charge-changing events in ion-atom collisions has been used to isolate and investigate excitation, ionization, and charge transfer, as well as combinations of these processes. New measurements were made of K-shell and L-shell resonant transfer and excitation (RTE) for 210 to 300 MeV 20 Ca/sup 10,11+/ + H 2 collisions and 230 to 610 MeV 41 Nb 31+ + H 2 collisions, respectively. Nonresonant transfer and excitation (NTE) was studied for 40 to 160 MeV S 13+ + Ne. Single-electron capture and loss measurements, requiring accel-decel techniques, were made for 2.5 to 200 MeV S 13+ on He. In the case of Ca/sup 16,17,18,19 + / + H 2 collisions the single capture cross cross sections exhibit a nonmonotonic energy dependence which we attribute to RTE. Double-electron capture in single collisions was investigated for S 13+ + He and Ne and Ar 15+ + Ne and the cross sections were found to be 10 to 100 times smaller than the single-capture cross sections. Measured two-electron loss cross sections for Ca/sup q + / ions incident on H 2 vary with charge state and depend strongly on whether L- or K-shell electrons are removed. Measurements of simultaneous projectile excitation and electron loss for several collision systems indicate that K-vacancy production occurs primarily through excitation rather than loss of the 1s electron. 13 refs

    Hertel, Ingolf V.; Schulz, Claus-Peter [Max-Born-Institut fuer Nichtlineare Optik und Kurzzeitspektroskopie im Forschungsverbund Berlin e.V. (Germany)

    2015-09-01

    This is the second volume of textbooks on atomic, molecular and optical physics, aiming at a comprehensive presentation of this highly productive branch of modern physics as an indispensable basis for many areas in physics and chemistry as well as in state of the art bio- and material-sciences. It primarily addresses advanced students (including PhD students), but in a number of selected subject areas the reader is lead up to the frontiers of present research. Thus even the active scientist is addressed. This volume 2 introduces lasers and quantum optics, while the main focus is on the structure of molecules and their spectroscopy, as well as on collision physics as the continuum counterpart to bound molecular states. The emphasis is always on the experiment and its interpretation, while the necessary theory is introduced from this perspective in a compact and occasionally somewhat heuristic manner, easy to follow even for beginners.

  2. Measurements of scattering processes in negative ion-atom collisions: Progress report, 1 September 1988--31 August 1989

    International Nuclear Information System (INIS)

    Kvale, T.J.

    1989-01-01

    The main emphasis of this research effort is the simultaneous study of several of the scattering processes that occur in negative ion-atom collisions. These include: elastic scattering, target excitation/ionization, single electron detachment, and double electron detachment. The measurements will provide absolute total and differential cross sections for the aforementioned processes. These are extremely valuable in providing stringent tests of the approximations used in the various theoretical calculations. This period covers the first year of the grant and the vast majority of the activity was directed toward construction of the apparatus needed to carry out the proposed measurements. Progress toward these goals are summarized. 2 refs., 1 fig

    This paper summarises recent progress in the physics basis and its impact on the expected performance of ITER. Significant progress has been made in many outstanding issues and in the development of hybrid and steady state operation scenarios, leading to increased confidence of achieving ITER's goals. Experiments show that tailoring the current profile can improve confinement over the standard H-mode and allow an increase in beta up to the no-wall limit at safety factors ∼ 4. Extrapolation to ITER suggests that at the reduced plasma current of ∼ 12MA, high Q > 10 and long pulse (>1000 s) operation is possible with benign ELMs. Analysis of disruption scenarios has been performed based on guidelines on current quench rates and halo currents, derived from the experimental database. With conservative assumptions, estimated electromagnetic forces on the in-vessel components are below the design target values, confirming the robustness of the ITER design against disruption forces.

  4. High Energy Physics Group. Annual progress report, fiscal year 1983

    International Nuclear Information System (INIS)

    1983-01-01

    Perhaps the most significant progress during the past twelve months of the Hawaii experimental program, aside from publication of results of earlier work, has been the favorable outcome of several important proposals in which a substantial fraction of our group is involved: the Mark II detector as first-up at the SLC, and DUMAND's Stage I approval, both by DOE review panels. When added to Fermilab approval of two neutrino bubble-chamber experiments at the Tevatron, E632 and E646, the major part of the Hawaii experimental program for the next few years is now well determined. Noteworthy in the SLAC/SLC/Mark II effort is the progress made in developing silicon microstrip detectors with microchip readout. Results from the IMB(H) proton decay experiment at the Morton Salt Mine, although not detecting proton decay, set the best lower limit on the proton's lifetime. Similarly the Very High Energy Gamma Ray project is closely linked with DUMAND, at least in principle, since these gammas are expected to arise from pi-zero decay, while the neutrinos come from charged meson decay. Some signal has been seen from Cygnus X-3, and other candidates are being explored. Preparations for upgrading the Fermilab 15' Bubble Chamber have made substantial progress. Sections of the Progress Report are devoted to VAX computer system improvements, other hardware and software improvements, travel in support of physics experiments, publications and other public reports, and last analysis of data still being gleaned from experimental data taken in years past (PEP-14 and E546, E388). High energy physics theoretical research is briefly described

  7. Self-organization of progress across the century of physics

    Science.gov (United States)

    Perc, Matjaž

    2013-04-01

    We make use of information provided in the titles and abstracts of over half a million publications that were published by the American Physical Society during the past 119 years. By identifying all unique words and phrases and determining their monthly usage patterns, we obtain quantifiable insights into the trends of physics discovery from the end of the 19th century to today. We show that the magnitudes of upward and downward trends yield heavy-tailed distributions, and that their emergence is due to the Matthew effect. This indicates that both the rise and fall of scientific paradigms is driven by robust principles of self-organization. Data also confirm that periods of war decelerate scientific progress, and that the later is very much subject to globalisation.

    We study the physics of electron-proton collisions in the range of centre-of-mass energies between √s approx.= 0.3 TeV (HERA) and √s approx.= (1-2) TeV. The latter energies would be achieved if the electron or positron beam of LEP [Esub(e) approx.= (50-100) GeV] is made to collide with the proton beam of LHC [Esub(p) approx.= (5-10) TeV]. (orig.)

    2018-06-01

    New phenomena involving pseudorapidity and azimuthal correlations among final-state particles in pp collisions at the LHC can hint at the existence of hidden sectors beyond the Standard Model. In this paper we rely on a correlated-cluster picture of multiparticle production, which was shown to account for the ridge effect, to assess the effect of a hidden sector on three-particle correlations concluding that there is a potential signature of new physics that can be directly tested by experiments using well-known techniques.

    1998-01-01

    Ultra-relativistic heavy-ions carry strong electromagnetic and nuclear fields. Interactions between these fields in peripheral nucleus-nucleus collisions can probe many interesting physics topics. This presentation will focus on coherent two-photon and photonuclear processes at RHIC. The rates for these interactions will be high. The coherent coupling of all the protons in the nucleus enhances the equivalent photon flux by a factor Z 2 up to an energy of ∼ 3 GeV. The plans for studying coherent interactions with the STAR experiment will be discussed. Experimental techniques for separating signal from background will be presented

    International Nuclear Information System (INIS)

    McCurdy, C.W.; Miller, W.H.

    1980-01-01

    Methods are described which effectively solve two of the technical difficulties associated with applying classical S-matrix theory to inelastic/reactive scattering. Specifically, it is shown that rather standard numerical methods can be used to solve the ''root search'' problem (i.e., the nonlinear boundary value problem necessary to impose semiclassical quantum conditions at the beginning and the end of the classical trajectories) and also how complex classical trajectories, which are necessary to describe classically forbidden (i.e., tunneling) processes, can be computed in a numerically stable way. Application is made to vibrational relaxation of H 2 by collision with He (within the helicity conserving approximation). The only remaining problem with regard to applying classical S-matrix theory to complex collision processes has to do with the availability of multidimensional uniform asymptotic formulas for interpolating the ''primitive'' semiclassical expressions between their various regions of validity

  13. Positron-atom collisions

    International Nuclear Information System (INIS)

    Drachman, R.J.

    1984-01-01

    The past decade has seen the field of positron-atom collisions mature into an important sub-field of atomic physics. Increasingly intense positron sources are leading towards a situation in which electron and positron collision experiments will be on almost an equal footing, challenging theory to analyze their similarities and differences. The author reviews the advances made in theory, including dispersion theory, resonances, and inelastic processes. A survey of experimental progress and a brief discussion of astrophysical positronics is also included. (Auth.)

    This report contains information regarding that part of the work performed at the General Physics Section of AB Atomenergi during the period July 1969 - July 1970, which has been supported by grants from the Swedish Board of Technical Development (STU). For projects still in progress the current status is described, for terminated projects, or distinguishable parts thereof, a summary is given. Where available, reports describing the work are listed. A substantial part of our resources has been concentrated on the physics of energy conversion: Investigation of recombination processes in a pulsed helium discharge; Theoretical and experimental investigation of MHD gas flow; Isotopic battery in the muW-range. Our section's interest in nuclear dosimetry and the general aspects of metrology has been manifested in two additional projects: Application of mass spectrometry on He in solids to analysis, nuclear physics and material technology; Servo system filter. As general information it can be added that other, not STU-supported, activities of the section are material dosimetry for irradiation monitoring and a fairly broad range of radiation shielding activities

  15. Advanced teaching labs in physics - celebrating progress; challenges ahead

    Science.gov (United States)

    Peterson, Richard

    A few examples of optical physics experiments may help us first reflect on significant progress on how advanced lab initiatives may now be more effectively developed, discussed, and disseminated - as opposed to only 10 or 15 years back. Many cooperative developments of the last decade are having profound impacts on advanced lab workers and students. Central to these changes are the programs of the Advanced Laboratory Physics Association (ALPhA) (Immersions, BFY conferences), AAPT (advlab-l server, ComPADRE, apparatus competitions, summer workshops/sessions), APS (Reichert Award, FEd activities and sessions), and the Jonathan F. Reichert Foundation (ALPhA support and institution matched equipment grants for Immersion participants). Broad NSF support has helped undergird several of these initiatives. Two of the most significant challenges before this new advanced lab community are (a) to somehow enhance funding opportunities for teaching equipment and apparatus in an era of minimal NSF equipment support, and (b) to help develop a more complementary relationship between research-based advanced lab pedagogies and the development of fresh physics experiments that help enable the mentoring and experimental challenge of our students.

New interfaces and models introduced recently in Geant4 10.3 are already used in LHC applications and may be useful for any type of simulation. Additional developments for EM physics are available with the new public version Geant4 10.4 (December, 2017). Important developments for calorimetry applications were carried out for the modeling of single and multiple scattering of charged particles. Corrections to scattering of positrons and to sampling of displacement have recently been added to the Geant4 default Urban model. The fully theory-based Goudsmit-Saunderson (GS) model for electron/positron multiple scattering was recently reviewed and a new improved version is available in Geant4 10.4. For testing purposes for novel calorimeters we provide a configuration of electron scattering based on the GS model or on the single scattering model (SS) instead of the Urban model. In addition, the GS model with Mott corrections enabled is included in the option4 EM physics constructor. This EM configuration provides the most accurate results for scattering of electrons and positrons.

  18. Progress in high-energy cosmic ray physics

    We review some of the recent progress in our knowledge about high-energy cosmic rays, with an emphasis on the interpretation of the different observational results. We discuss the effects that are relevant to shape the cosmic ray spectrum and the explanations proposed to account for its features and for the observed changes in composition. The physics of air-showers is summarized and we also present the results obtained on the proton-air cross section and on the muon content of the showers. We discuss the cosmic ray propagation through magnetic fields, the effects of diffusion and of magnetic lensing, the cosmic ray interactions with background radiation fields and the production of secondary neutrinos and photons. We also consider the cosmic ray anisotropies, both at large and small angular scales, presenting the results obtained from the TeV up to the highest energies and discuss the models proposed to explain their origin.

    During the last three years, the experimental activities have concentrated on several somewhat distinct projects. First, the author has measured total cross sections for electron detachment and charge transfer for collisions of various negative ions with atomic hydrogen and the molecular target, O 3 (ozone). The second type of gas phase experiments investigated the collisional decomposition of the molecular ion H 3 + . Specifically he has measured total cross sections for dissociation and proton transfer with an apparatus utilizing a static gas target cell. The targets include hydrogen, deuterium and the rare gases. He has extended these experiments to include D 3 + in a crossed beam configuration in order to provide a more detailed understanding of the collisional dynamics for these reactants. In the area of ion-surface collisions he has measured sputtering yields for O - and electrons arising from collisions of ions with an Al/O surface. The amount of oxygen on the surface is carefully controlled and the kinetic energy distributions of the ejected anions and electrons have been determined. He has been able to develop a theoretical model which, to a large degree, can describe the process. In a slightly speculative endeavor, he has begun investigating the role of atom-catalyzed field emission, i.e., the extent to which an unoccupied negative ion state for an atom near a surface--under the influence of a strong electric field--can serve as a stepping-stone for electron field emission. Very brief accounts of these activities will be given in this report in section 2. Detailed discussions of the experimental results and their analyses published during the contract period may be found in the following articles which have appeared in the archival literature. Copies of these publications are appended to this report as section 4

    The two progress reports PR-PHS-P-1 (AECL-9262) and PR-PHS-HS-1 (AECL-9263) are continuations of the former series in Physics, PR-P-142, (AECL-9103) and in Health Sciences, PH-HS-20 (AECL-9102). The new series have been initiated to take into account the reorganization of the Research Company effective 1986 February 1. It is intended to issue the reports semi-annually on June 30 and December 31 covering the previous six months. The new series cover the same areas as before except that the Accelerator Physics Branch and the Mathematics and Computation Branch activities are no longer included in Physics, and the activities of the Medical Biophysics Branch at Whiteshell are now included in Health Sciences. The latest progress report on the Medical Biophysics work appeared in the WNRE report PR-WHS-73. This report (AECL-9262) covers the research, business and commercial activities of Nuclear Physics, TASCC Operations, Neutron and Solid State Physics, Theoretical Physics and the Fusion Office

    1976-02-01

    Summaries of research progress on ion--atom collisions are given. Electron capture by high velocity point charges (bare nuclei with Z less than or equal to 9) was studied in several ways. Studies on the nuclear reactions induced by 13 C and 9 Be ions near the Coulomb barrier have continued

  2. Recent progress in nonperturbative electromagnetic lepton-pair production with capture in relativistic heavy-ion collisions

    1993-01-01

    The prospect of new colliding-beam accelerators capable of producing collisions of highly stripped high-Z ions, at fixed-target energies per nucleon up to 20 TeV or more, has motivated much interest in lepton-pair production from the QED vacuum. The time-dependent and essentially classical electromagnetic fields involved in such collisions contain larger Fourier components which give rise to sizable lepton-pair production in addition to many other exotic particles. The process of electron-positron production with electron capture is a principal beam-loss mechanism for highly charged ions in a storage ring. In this process, the electron is created in a bound state of one of the participant heavy ions (most likely the 1s state), thus changing the ion's charge state and causing it to be deflected out of the beam. There is a long and sometimes controversial history concerning the use of perturbative methods in studying electromagnetic lepton-pair production; however, reliable perturbative calculations have been used as input into design models for the Relativistic Heavy-Ion Collider (RHIC). Applying perturbation theory to these processes at high energies and small impact parameters results in probabilities which violate unitarity, and cross sections which violate the Froissart bound. This evidence, along with the initial nonperturbative studies, suggests that higher-order QED effects will be important for extreme relativistic collisions. Clearly, large nonperturbative effects in electron-pair production with capture would have important implications for RHIC. In this paper, the authors briefly discuss recent progress in nonperturbative studies of the capture problem. In Section 2, they state the Dirac equation for a lepton in the time-dependent external field of a heavy ion which must be solved to compute lepton-capture probabilities. Section 4 surveys results from recent applications of coupled-channel and lattice techniques to the lepton-capture problem

    International Nuclear Information System (INIS)

    Kvale, T.J.

    1994-01-01

    This report describes the progress made on the research objectives during the past three years of the grant. This research project is designed to study various scattering processes which occur in H - collisions with atomic (specifically, noble gas and atomic hydrogen) targets in the intermediate energy region. These processes include: elastic scattering, single- and double-electron detachment, and target excitation/ionization. For the elastic and target inelastic processes where H - is scattered intact, the experimental technique of Ion Energy-Loss Spectroscopy (IELS) will be employed to identify the final target state(s). In most of the above processes, cross sections are unknown both experimentally and theoretically. The measurements will provide total cross sections (TCS) initially, and once the angular positioning apparatus is installed, will provide angular differential cross sections (ADCS)

  7. Progress report. Physics and Health Sciences, Physics Section (1987 January 01-June 30)

    International Nuclear Information System (INIS)

    1987-12-01

    This report covers the third semi-annual period since the Research Company was reorganized. A highlight of the period was the first peer review of all the activities in Physics and Health Sciences by external examiners. The review was conducted in April by three separate Technical Review Committees (TRC) one for each of the three main areas: health sciences, nuclear physics and condensed matter physics. In all cases the TRCs gave strong support to our programs under the following mandate. To assess research programs with respect to (a) their quality, and (b) their relevance to Canada. The programs by the Nuclear Physics TRC reviewed were: heavy ion reaction studies; gamma-ray studies of high spin states; exotic nuclei and weak interactions; neutron and neutrino physics; TASCC operation and development; and theoretical physics. The programs reviewed by the Condensed Matter TRC were: liquid helium; amorphous ice; orientationally disordered solids; structural phase transitions; low dimensional systems; actinide magnetism and heavy fermion superconductors; molecular biophysics; applied neutron diffraction (ANDI); and theoretical solid state physics. A mechanism for the evaluation of the strategy for the National Fusion Program has been developed and the process is under way. The successful completion of the 8-pi spectrometer by Chalk River and the Universities of Montreal and McMaster, plus the vigorous and highly successful experimental program in progress on it were the outstanding achievement of the period. Good progress is being made in the detailing of a program in heavy ion nuclear reactions, and the specification of equipment for that program have been made. Some difficulties with the new Vivirad resistors for the MP tandem were encountered, however the manufacturer now seems to have solved the problem

  8. Analysis of In-Flight Collision Process During V-Type Firing Pattern in Surface Blasting Using Simple Physics

    Blasting is a unit operation in Mine-Mill Fragmentation System (MMFS) and plays a vital role in mining cost. One of the goals of MMFS is to achieve optimum fragment size at minimal cost. Blast fragmentation optimization is known to result in better explosive energy utilization. Fragmentation depends on the rock, explosive and blast design variables. If burden, spacing and type of explosive used in a mine are kept constant, the firing sequence of blast-holes plays a vital role in rock fragmentation. To obtain smaller fragmentation size, mining professionals and relevant publications recommend V- or extended V-pattern of firing sequence. In doing so, it is assumed that the in-flight air collision breaks larger rock fragments into smaller ones, thus aiding further fragmentation. There is very little support to the phenomenon of breakage during in-flight collision of fragments during blasting in published literature. In order to assess the breakage of in-flight fragments due to collision, a mathematical simulation was carried over using basic principles of physics. The calculations revealed that the collision breakage is dependent on velocity of fragments, mass of fragments, the strength of the rock and the area of fragments over which collision takes place. For higher strength rocks, the in-flight collision breakage is very difficult to achieve. This leads to the conclusion that the concept demands an in-depth investigation and validation.

    1983-01-01

    The progress of work done in the Theoretical Reactor Physics Section of the Bhabha Atomic Research Centre, Bombay, during the calendar year 1982 is reported in the form of write-ups and summaries. The main thrust of the work has been to master the neutronic design technology of four different types of nuclear reactor types, namely, pressurized heavy water reactors, boiling light water reactors, pressurized light water reactors and fast breeder reactors. The development work for the neutronic analysis, fuel design, and fuel management of the BWR type reactors of the Tarapur Atomic Power Station has been completed. A new reactor simulator system for PHWR design analysis and core follow-up was completed. Three dimensional static analysis codes based on nodal and finite element methods for the design work of larger size (500-750 MWe) reactors have been developed. Space link kinetics codes in one, two and three dimensions for above-mentioned reactor systems have been written and validated. Fast reactor core disruptive analysis codes have been developed. In the course of R and D work concerning various types of reactor projects, investigations were also carried in the allied areas of Monte Carlo techniques, integral transform methods, path integral methods, high spin states in heavy nuclei and a hydrodynamics model for a laser driven fusion system.

    1990-01-01

    Task D's research is focused on the understanding of elementary particle physics through the techniques of quantum field theory. We make intensive use of computers to aid our research. During the last year we have made significant progress in understanding the weak interactions through the use of Monte Carlo methods as applied to the equations of quenched lattice QCD. We have launched a program to understand full (not quenched) lattice QCD on relatively large lattices using massively parallel computers. Because of our awareness that Monte Carlo methods might not be able to give a good solution to field theories with the computer power likely to be available to us for the forseeable future we have launched an entirely different numerical approach to study these problems. This ''Source Galerkin'' method is based on an algebraic approach to the field theoretic equations of motion and is (somewhat) related to variational and finite element techniques applied to a source rather than a coordinate space. The results for relatively simple problems are sensationally good. In particular, fermions can be treated in a way which allows them to retain their status as independent dynamical entities in the theory. 8 refs

    The experimental program of research, including Assembly of an experiment at Fermilab E-351 to measure decay lifetimes, with tagged emulsion, of charmed particles produced by high energy neutrinos will continue. A data-taking run will take place in the coming fiscal year. Participation in the neutrino experiment E-310, Fermilab-Harvard-Pennsylvania-Rutgers-Wisconsin, will also continue. Data analysis from several experiments performed in the recent past at the ZGS ANL is in progress and will be pursued. These experiments are, E-397, E-420 and E-428 performed with the Charged and Neutral Spectrometer, and E-347 with the Σ/sub β/ Spectrometer. Plans are in the making to collaborate with a polarized proton experiment at the ZGS. New approaches to ''third generation'' neutrino experiments at Fermilab are being discussed by the whole high energy group. Ideas of pursuing experiments at the AGS-BNL with the Σ/sub β/ Spectrometer are explored. The theoretical research program covers topics of current interest in particle theory which will be investigated in the coming year; namely, the role of instantons in quantum chromodynamics, Higgs Lagrangian involving scalar fields, phenomenology of neutrino physics and in particular the nature of trimuon production, higher order symmetries like SU(3) x U(1) SU(5) and SU(6), dynamics of high energy diffractive scattering, classical solutions to the gauge field theories

    1991-05-01

    A completely new administrative structure of AECL Research was implemented on 1990 July 1. All of the basic physics programs, together with accelerator physics, radiation applications and most of the chemistry programs of AECL, have been placed in a new organizational unit called Physical Sciences. This unit also includes the management of the National Fusion Program. The research programs of Physical Sciences are grouped into three divisions: Chemistry, Physics and TASCC. Progress in each division will henceforth be reported on a twice-yearly basis. This report is the first of the new series to be issued by the Physics Division. Of special note within the period covered by this report was the successful acceleration of over 75 mA of protons to 600 keV in RFQ1 making it the highest current RFQ in the world. Our electron accelerator expertise has been recognized by the award of one of the R and D 100 awards for the IMPELA (10 MeV 50 kW) machine. Considerable activity was associated with bringing the new dual beam neutron spectrometer DUALSPEC to completion. This instrument has been jointly funded by AECL and NSERC through McMaster University and will be a central component of the national neutron scattering facility at NRU in the 1990's. A major effort was made with the writing of a Project Definition Document for installation of a cold neutron source at the most opportune time

    The program is an investigation of the hadronization process through experimental measurement of rare particle production in high energy nuclear interactions. These interactions provide an environment similar in energy density to the conditions in the Big Bang. The authors are currently involved in two major experiments to study this environment, E896 at the AGS and STAR at RHIC. They have completed the first physics running of E896, a search for the H dibaryon and measurement of hyperon production in AuAu collisions, and are in the process of analyzing the data. They have prototyped the STAR trigger and are in the process of fabricating its components and installing them in the STAR detector

    The 7th edition of the Workshop for Young Scientists on the Physics of Ultra-relativistic Nucleus-Nucleus Collisions (Hot Quarks 2016) was held on South Padre Island, Texas, United States from September 12-17, 2016. Following the traditions of the conference, the meeting gathered almost 70 participants in the first years of their scientific careers. The present issue contains the proceedings of this workshop.As in the past, the Hot Quarks workshop offered a unique atmosphere for lively discussions and interpretation of the current measurements from high-energy nuclear collisions. Dedicated time at the end of each session for questions, including anonymous questions from the “box”, are crucial for this workshop. Recent results and upgrades at CERN's Large Hadron Collider (LHC) and Brookhaven's Relativistic Heavy Ion Collider (RHIC) were presented. Recent theoretical developments were also extensively discussed as well as the perspectives for future facilities such as the Facility for Antiproton and Ion Research (FAIR) at Darmstadt and the Electron-Ion Collider at Brookhaven. The conference's goal to provide a platform for young researchers to learn and foster their interactions was successfully met.We wish to thank the sponsors of the Hot Quarks 2016 Conference, who supported the authors of this volume: European Laboratory for Particle Physics CERN (Switzerland), Cyclotron Institute at Texas A and M University (USA), ExtreMe Matter Institute EMMI (Germany), Helmholtz Association and GSI under grant VH-NG-822 (Germany), Helmholtz International Center for FAIR (Germany), National Science Foundation (USA), Netherlands Organization for Scientific Research (Netherlands), Nuclear Physics Institute of the CAS (Czech Republic), the Ministry of Education, Youth and Sport (Czech Republic) and 3 sponsors who wish to remain anonymous.Javier López Albacete, Universidad de Granada (Spain)Jana Bielcikova, Nuclear Physics Inst. of the Czech Academy of Sciences

    In order to support the operation of ITER and the planned experimental programme an extensive set of plasma and first wall measurements will be required. The number and type of required measurements will be similar to those made on the present-day large tokamaks while the specification of the measurements-time and spatial resolutions, etc-will in some cases be more stringent. Many of the measurements will be used in the real time control of the plasma driving a requirement for very high reliability in the systems (diagnostics) that provide the measurements. The implementation of diagnostic systems on ITER is a substantial challenge. Because of the harsh environment (high levels of neutron and gamma fluxes, neutron heating, particle bombardment) diagnostic system selection and design has to cope with a range of phenomena not previously encountered in diagnostic design. Extensive design and R and D is needed to prepare the systems. In some cases the environmental difficulties are so severe that new diagnostic techniques are required. The starting point in the development of diagnostics for ITER is to define the measurement requirements and develop their justification. It is necessary to include all the plasma parameters needed to support the basic and advanced operation (including active control) of the device, machine protection and also those needed to support the physics programme. Once the requirements are defined, the appropriate (combination of) diagnostic techniques can be selected and their implementation onto the tokamak can be developed. The selected list of diagnostics is an important guideline for identifying dedicated research and development needs in the area of ITER diagnostics. This paper gives a comprehensive overview of recent progress in the field of ITER diagnostics with emphasis on the implementation issues. After a discussion of the measurement requirements for plasma parameters in ITER and their justifications, recent progress in the field of

The Accelerator Physics Group in collaboration with Fuel Channel Components Branch has undertaken a unique series of experiments to prove the feasibility of using high energy electron beams for out-reactor irradiation of bulk samples of pressure-tube materials. The Neutron and Condensed Matter Branch, has among other topics, been involved with the Sudbury Neutrino Observatory project. It is part of an international collaboration including Canada, United States, and the United Kingdom. The project involves the use of heavy water to detect particles called neutrinos that are emitted from the centre of the sun and from exploding stars. Results from the Molecular Physics program include a study of the differing structures of ice grown in an electric field. Atomic Ordering in the new intermetallics Al 3 Ti-X was extensively investigated in the Materials Science program. In the theory program a code to calculate the multiphonon expansion of the incoherent scattering function was written and it was applied in the analysis of phonon density of states for amorphous and crystalline ice. Further calculations were made to develop improved understanding of superconductivity and a theory for the conductivity of vortex cores was proposed. 3 tabs., 15 figs

    This document is a Progress Report for the Physical and Environmental Sciences, Physics Division, for the period 1995 January 1 to December 31, at the Chalk River nuclear Labs. The condensed matter science group continued to operate a multi-faceted program involving collaborative basic and applied research with external scientists in the fields of materials science, physics, chemistry and biology. The Applied Neutron Diffraction for Industry (And) program gained strength with ever wider applications for the nuclear, aerospace, and manufacturing programs. Steps continued towards making neutron scattering facilities at NRU reactor more user friendly. The neutrino physics group, as part of the Sudbury Neutrino Observatory (SNO) Institute, collaborating with scientists from Canada, USA and UK. The accelerator physics group spent considerable effort working with materials and fuels scientists to show the value of accelerators as an out-reactor source of radiation. Specific research activities have included the demonstration of laser plasma deposition of diamond coating, which has potential application for high-wear components in reactors, and the study for a Free Electron Laser upgrade for the IMPELA accelerator. As a result of funding reduction all programs of the Division were dissolved as of 1997 March 31.

    1991-09-01

    This is the second in the new series of reports for the Physics Division since the creation of the Physical Sciences Unit in 1990. This report has been subdivided into three self-contained sections covering the activities in the branches for Accelerator Physics, Neutron and Solid State Physics and Theoretical Physics. It is noteworthy that the RFQ1 program with the original vanes has come to a successful conclusion having accelerated 79 mA of protons to 600 keV. The new vanes to achieve a high energy of 1.2 MeV have now been installed and will form the basis for the low energy end of high current proton accelerator development. The progress in the neutron scattering program has been hampered by the NRU reactor being down for repairs since January 1991. Nevertheless a very successful opening ceremony was held to mark the completion of the new DUALSPEC spectrometers and several workshops have been held to promote the understanding of neutron scattering

    Correlations between x-ray emission and projectile charge-changing events have been investigated for highly charged ions incident on gas targets under single collision conditions. Measurements were made for 100 to 360 MeV 20 Ca/sup 16,17,18+/ + He, 15 to 200 MeV 16 S 13+ + He, 100 to 370 MeV 20 Ca/sup 12,16,17,18,19+/ + H 2 , and 455 to 705 MeV 57 La 40+ + H 2 . Coincidences between electron capture and K x-ray emission for Ca/sup q+/ + H 2 and He, combined with previous measurements for 180 to 460 MeV 23 V/sup 19,20,21+/ + He, demonstrate the existence and substantiate the theory of resonant transfer and excitation (RTE). Additional K-shell RTE studies include theoretical calculations of the cross sections for Li-like ions with 14 less than or equal to Z less than or equal to 26 incident on He and Ne. The 57 La 40+ + H 2 measurements provide evidence for L-shell RTE. For S 13+ + He new evidence is obtained for nonresonant transfer and excitation, a two-step process in which uncorrelated electron capture and projectile excitation occur in a single encounter. Total electron capture cross sections for S 13+ + He vary by about 10 5 over the energy range investigated and are in reasonable agreement with empirical values. Other studies of electron capture and loss include measurements of the charge-state dependence for V/sup q+/ + He (q = 18 to 23) at 8.55 MeV/amu

  13. Heavy Flavor Physics in Heavy-Ion Collisions with STAR Heavy Flavor Tracker

    Heavy quarks are a unique tool to probe the strongly interacting matter created in relativistic heavy-ion collisions at RHIC energies. Due to their large mass, energetic heavy quarks are predicted to lose less energy than light quarks by gluon radiation when they traverse a Quark-Gluon Plasma. In contrast, recent measurements of non-photonic electrons from heavy quark decays at high transverse momentum (p T ) show a jet quenching level similar to that of the light hadrons. Heavy quark are produced mainly at early stage in heavy-ion collisions, thus they are proposed to probe the QCD medium and to be sensitive to bulk medium properties. Ultimately, their flow behavior may help establish whether light quarks thermalize. But due to the absence of the measurement of B-mesons and precise measurement of D-mesons, it is difficult to separate bottom and charm contributions experimentally in current non-photonic electron measurements for both spectra and elliptic flow v 2 . Therefore, topological reconstruction of D-mesons and identification of electrons from charm and bottom decays are crucial to understand the heavy flavor production and their in medium properties. The Heavy Flavor Tracker (HFT) is a micro-vertex detector utilizing active pixel sensors and silicon strip technology. The HFT will significantly extend the physics reach of the STAR experiment for precise measurement of charmed and bottom hadrons. We present a study on the open charm nuclear modification factor, elliptic flow v 2 and λ c measurement as well as the measurement of bottom mesons via a semi-leptonic decay. (author)

    Full Text Available  Aims: Investigate subjective health complaints (SHC in chronic whiplash associated disorder (WAD, grade I & II patients, and to identify physical, psychological, and collision associated factors that might be associated with high levels of comorbidity. Method: During the years 2000-2002 171 chronic WAD patients filled in questionnaires and underwent physical examination. The prevalence of SHC was recorded and compared with a representative sample of the Norwegian population (n=1014. Results: The chronic WAD patients reported higher number of subjective health complaints (median: 9 than the general population (median: 5. They showed significantly higher risk of reporting all musculoskeletal complaints, palpitation, heat flushes, sleep problems, tiredness, dizziness, anxiety, depression, breathing difficulties, chest pain, coughing, heartburn, gas discomfort, and obstipation. The patients with the highest level of comorbid subjective health complaints also reported more function loss, reading difficulties, poorer quality of life, higher psychological distress, higher use of medication, and less optimism about their situation. There were no differences however, in any collision factors or physical meassures recorded by physiotherapists between the high, medium and low comorbidity groups. Conclusion: The high comorbidity of other complaints, the strong relationships between degree of comorbidity and psychological factors, and the lack of relationships between degree of comorbidity and collision factors and physical tests, suggest that chronic WAD is best understood as a syndrome and not simply as a neck injury. Sensitization is suggested as a possible psychobiological mechanism

  11. Theory of high-energy-collision processes. Technical progress report, January 1-December 31, 1981

    International Nuclear Information System (INIS)

    1982-01-01

    Progress is described in the following areas: (1) several years ago, surprisingly simple expressions were obtained for the differential cross sections of e + e - → μ + μ - γ and e + e - → e + e - γ at high energies. Such simple expressions were generalized to twelve other similar radiative processes in QED and QCD. Afterwards, it was found that these results can be derived easily with the help of helicity amplitudes. This method is being investigated for many other radiative processes; (2) in the two-dimensional Ising model, the horizontal and vertical interaction energies are usually taken to be different. When this idea of different interactions in different directions is applied to the Z 2 lattice gauge theory in four dimensions, a limiting case is found which is exactly solvable. Contrary to numerical calculations at the symmetry point, the phase transition is found to be of second order; (3) on the subject of supersymmetry, general helicity and spin sum rules were obtained for massless and massive supermultiplets, and a functional integral approach was found as a natural setting for Witten's criterion for the occurrence of dynamic symmetry breaking of supersymmetry. A systematic and exhaustive analysis of explicit soft breaking of global supersymmetry has also been carried out using the methods of superfields; (4) the renormalization of the massless Thirring model in the neighborhood of g = -π/2 was studied. The results are consistent with those found previously by placing the model on a lattice; and (5) in studying the effect of laboratory temperature on scattering processes, it was found that transport phenomena play an important role. As a preparation for this study, an exactly solvable case of the nonlinear Boltzmann equation has been found and studied

    The activities of this Division are concentrated in the areas of experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. A major activity within the Division is operation of the Holifield Heavy Ion Research Facility as a national user facility. Highlights for this year, which include a record number of beam hours provided for research, are summarized. The experimental nuclear physics program continues to be dominated by research utilizing heavy ions. These activities, while continuing to center largely on the Holifield Facility, have seen growth in the use of facilities that provide intermediate energies (GANIL) and ultrarelativistic beams (CERN). The UNISOR program, since its inception, has been intimately associated with the Division and, most particularly, with the Holifield Facility. The experimental nuclear structure research of this consortium is included. In addition to the Holifield Facility, the Division also operates two smaller facilities, the EN Tandem and the ECR Ion Source Facility, as /open quotes/User Resources/close quotes/. The tandem continues a long history of supporting research in accelerator-based atomic physics. During this past year, new beam lines have been added to the ECR ion source to create user opportunities for atomic physics experiments with this unique device. These two facilities and the experimental programs in atomic physics are discussed. The efforts in theoretical physics, covering both nuclear and atomic physics, are presented. Also included is the theory effort in support of the UNISOR structure program. In addition to research with multicharged heavy ions from the ECR source, the effort on atomic physics in support of the controlled fusion program includes a plasma diagnostics development program and operation of an atomic physics data center.

    The period covered by this report is outstanding because of the spectacular progress made in the construction of the TANDAB facility. In January 1980, the excavation work had just started; by December 1981 the column structure was standing in the interior of the 35m high pressure vessel and the injector was being readied at its definitive location 56m above ground. During 1980 there was a vigorous local drive to meet the schedule for the column installation as agreed with NEC. The main and service towers reached the top at 73m at a fast pace by using nonstop sliding forms. Previously the pressure tank had been finished and tested to a maximum 18 kg/cm 2 pressure in record time. Shortly afterwards the two spherical storage vessels for the SF 6 gas were completed. At present, most of the work is being geared to complete the gas handling system and start the high voltage tests. On the occasion of the T hird International Conference on Electrostatic Accelerator Technology , we were awarded the distinction of being selected as hosts for the next conference in 1985. We hope that our accelerator will be well ahead in the running stage by then. It is also possible that the adjacent office building originally planned will also be ready for the conference. The training program which was initiated in 1977 with the purpose of supplementing adequately the research staff needed for an efficient use of the TANDAR is near completion now. This program has involved a dozen young physicists who have finished or are finishing their theses. Most of them have had the opportunity to get experience abroad. Now that the program is almost completed we can be very satisfied with the results. In this connection we wish to acknowledge the collaboration of those groups abroad which have been willing to host the young graduates in Oxford, Muenchen, Goettingen, Heidelberg, Stony Brook, Oak Ridge, Seattle, Berkeley and Rehovot. We keep high expectations on the returns of this program which should

The activities of this Division are concentrated in the areas of experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. Operation of the Holifield Heavy Ion Research Facility as a national user facility continues to represent the single largest activity within the Division. This year saw the completion of the acceleration tube upgrade of the 25-MV tandem electrostatic accelerator and the achievement of record terminal potentials, operation for an experiment with 25 million volts on terminal, and successful tests with beam at 25.5 MV. The experimental nuclear physics program continues to be dominated by research utilizing heavy ions. These activities, while continuing to center largely on the Holifield Facility, have seen significant growth in the use of facilities that provide intermediate energies and especially ultrarelativistic beams. The UNISOR program, since its inception, has been intimately associated with the Division and, most particularly, with the Holifield Facility. In addition to the Holifield Facility, the Division operates two smaller facilities, the EN Tandem and the ECR Ion Source Facility, as ''User Resources.'' The efforts in theoretical physics, covering both nuclear and atomic physics, are presented. In addition to research with multicharged heavy ions from the ECR source, the effort on atomic physics in support of the controlled fusion program includes a plasma diagnostics development program. The concentration of this program on optical and laser technology is marked by the change in designation to the Laser and Electro-Optics Lab. A small, continuing effort in elementary particle physics, carried out in collaboration with the University of Tennessee, is reported.

This year saw the completion of the acceleration tube upgrade of the 25-MV tandem electrostatic accelerator and the achievement of record terminal potentials, operation for an experiment with 25 million volts on terminal, and successful tests with beam at 25.5 MV. The experimental nuclear physics program continues to be dominated by research utilizing heavy ions. These activities, while continuing to center largely on the Holifield Facility, have seen significant growth in the use of facilities that provide intermediate energies and especially ultrarelativistic beams. The UNISOR program, since its inception, has been intimately associated with the Division and, most particularly, with the Holifield Facility. In addition to the Holifield Facility, the Division operates two smaller facilities, the EN Tandem and the ECR Ion Source Facility, as ''User Resources.'' The efforts in theoretical physics, covering both nuclear and atomic physics, are presented. In addition to research with multicharged heavy ions from the ECR source, the effort on atomic physics in support of the controlled fusion program includes a plasma diagnostics development program. The concentration of this program on optical and laser technology is marked by the change in designation to the Laser and Electro-Optics Lab. A small, continuing effort in elementary particle physics, carried out in collaboration with the University of Tennessee, is reported

    The activities of the Division during 1984/85 were again directed towards the general program objectives of the past two years. A shift in emphasis resulted in some organization changes. The increased importance of nuclear safeguards research in the Government's support for the International Atomic Energy Agency program has prompted a re-arrangement of the nuclear physics and science activities. Dr JR. Bird holds the responsibility for the Nuclear Science Section comprising the Nuclear Applications Group, Biomedical and Reactor Applications Group and the Neutron Scattering Group. The newly formed Safeguards and Nuclear Physics Section is headed by Dr J.W. Boldeman and includes the Safeguards Group and Nuclear Physics Group. The organization of the remainder of the Division is unchanged. The work on the electronic properties of hydrogen in silicon has been particularly rewarding and the plasma physics studies received recognition with an IAEA sponsored workshop on Compact Torus Research held in Sydney in March 1985 (author)

    The Physics Division is organized into three major research areas: Weapons Physics, Inertial Fusion Physics, and Basic Research. In Weapons Physics, new strategic defensive research initiatives were developed in response to President Reagan's speech in May 1983. Significant advances have been made in high-speed diagnostics including electro-optic technique, fiber-optic systems, and imaging. In Inertial Fusion, the 40-kJ Antares CO 2 laser facility was completed, and the 1- by 1- by 2-m-long large-aperture module amplifier (LAM) was constructed and operated. In Basic Research, our main emphasis was on development of the Weapons Neutron Research (WNR) facility as a world-class pulsed neutron research facility

    The activities of this Division continue to be concentrated in the areas of experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. The Holifield Heavy Ion Research Facility and its operation as a national user facility continued as the single largest activity within the Division. The experimental nuclear physics program continues to emphasize heavy ion studies, with much of the activity centered at the Holifield Facility. The work with heavy ions at ultrarelativistic energies continues at the CERN SPS. Studies at the Brookhaven AGS, particularly in preparation of future experiments at RHIC, have seen an increased emphasis. A major consortium has been formed to propose the design and construction of a dimuon detector as the basis for one the principal experiments for RHIC. Also included are results from the increasing effort in particle physics, including participation in the L* proposal for the SSC. The UNISOR program, since its inception, has been associated intimately with the Division and, most particularly, with the Holifield Facility. A major area of experimental research for the Division is atomic physics. This activity comprises two groups: one on accelerator-based atomic physics, centered primarily at the EN-tandem and the Holifield Facility, but extending this year to an experiment at ultrarelativistic energies at the CERN SPS; and one on atomic physics in support of fusion energy, based primarily at the ECR ion source facility. Included in this section is also a description of a new effort in multicharged ion-surface interactions, and details of a planned upgrade of the ECR source

    The research activities of the Division are centered primarily in three areas: experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. The largest of these efforts, experimental nuclear physics, is dominated by the heavy ion research program. A major responsibility under this program is the operation of the Holifield Heavy Ion Research Facility as a national user facility. During the period of this report, the facility has begun routine operation for the experimental program. The experimental atomic physics program has two components: the accelerator-based studies of basic collisional phenomena and the studies in support of the controlled fusion program. Also associated with the fusion-related studies are a plasma diagnostics program and the operation of an atomic physics data center. The theoretical physics program, both nuclear and atomic, is covered. This program has benefited this year from the success of the VAX-AP computer system and from the increase in manpower provided by the ORNL/University of Tennessee Distinguished Scientist Program. Smaller programs in applications and high-energy physics are summarized. During the period of this report, we continued to explore possible future extensions of the Holifield Facility. We retain a strong interest in a relativistic heavy-ion collider in the 10 x 10 GeV/nuclear energy range. The ideas for such a facility, described in last year's report, have been modified to utilize the HHIRF 25 MV tandem accelerator as the first stage. Finally, the report concludes with some general information on publications, Division activities, and personnel changes.

    Research in the Physics Department at Risoe National Laboratory covers three main fields: Condensed Matter Physics, Plasma Physics and Meteorology. The principal activities in these fields for the period from 1 January to 31 December 1983 are described. The condensed matters physics research is predominantly experimental utilising diffraction of neutrons and X-rays. The research topics range from studies of structure, excitations and phase transitions in model systems to studies of ion transport, texture and recrystallization kinetics with a more applied nature. The plasma physics research is partly experimental and partly theoretical. A study of pellet-plasma interaction is of applied nature and aimed at assessing the possibilities of refuelling a fusion reactor by shooting deuterium-tritium pellets into the plasma. A study of the fundamental physics of plasmas deals with investigations of wave propagation properties, instabilities, solitons, turbulence, etc. The research and applied work within meteorology lies within micrometeorology and the subjects range from surface energy balance studies, over studies of the general structure of atmospheric coherence and boundary layer response to change in surface elevation, to specific studies of turbulent dispersion and deposition of airborne material. As part of the applied work within meteorology and wind energy, the test station for small windmills tests and licences windmills for the Danish market and offers consulting assistance for the Danish windmill manufacturers.

    The principal activities in the fields of solid-state physics (neutron scattering), plasma physics, nuclear spectroscopy and meteorology are presented. The main experimental and theoretical work in solid-state physics has involved: investigation of the static and dynamic properties of magnetic solids; studies of various kinds of phase transitions in solids and liquid-like systems; electronic energy band calculations of metals; and investigations of the structure and lattice dynamics of molecular crystals and adsorbed monolayers. The work of the plasma physics section is centered on technology of interest for future fusion reactors and on basic plasma physics. The technological aspects of plasma phsics are undertaken with one of the possible refuelling schemes for fusion reactors in mind. The main object of the basic research is investigations of waves and instabilites in a relatively cold steady state plasma. The activites in the field of nuclear spectroscopy have concerned an attempt to form the 236 U fission isomer with thermal neutrons and studies of the fine structure in the mass distribution for fission fragments. The meteorology section is primarily engaged in studies of the planetary boundary layer. (B.R.H.)

    Since 1992, the direct use of spent pressurized water reactor fuel in CANada Deuterium Uranium (CANDU) reactors (DUPIC) has been studied as an alternative to the once-through fuel cycle. The DUPIC fuel cycle study is focused on the technical feasibility analysis, the fabrication of DUPIC fuels for irradiation tests and the demonstration of the DUPIC fuel performance. The feasibility analysis was conducted for the compatibility of the DUPIC fuel with existing CANDU-6 reactors from the viewpoints of reactor physics, reactor safety, fuel cycle economics, etc. This study has summarized the intermediate results of the DUPIC fuel compatibility analysis, which includes the CANDU reactor physics design requirements, DUPIC fuel core physics design method, performance of the DUPIC fuel core, regional overpower trip setpoint, and the CANDU primary shielding. The physics analysis showed that the CANDU-6 reactor can accommodate the DUPIC fuel without deteriorating the physics design requirements by adjusting the fuel management scheme if the fissile content of the DUPIC fuel is tightly controlled.

    This report covers the research and development activities of the Physics Division for the 1995 and 1996 fiscal years, beginning October 1, 1994, and ending September 30, 1996. The activities of the Division continue to be concentrated in the areas of experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. In addition, there are smaller programs in plasma diagnostics and data compilation and evaluation. During the period of this report, there has been considerable success in bringing the Holifield Radioactive Ion Beam Facility (HRIBF) into routine operation. The budgets of the nuclear physics portion of the Division have increased each year in nearly all areas, and several new members have been added to the Division research and development staff. On August 30, 1996, the HRIBF successfully accelerated its first radioactive ion beams, 69 As and 70 As. Prior to this, the heart of the facility, the RIB injector system, was completed, including installation of a remote handling system for the target/ion source assembly. Target and ion source development is likely to be the technical key to success of the HRIBF. We have expanded our efforts in those development areas. Of special note is the development of highly permeable composite targets which have now been shown to allow release of difficult-to-produce radioactive ions such as 17,18 F. A summary of the HRIBF work is provided in Chapter 1, along with supporting activities of the Joint Institute for Heavy Ion Research

A total of 263 papers were identified in a systematic database search of PubMed/Medline and Embase. Five steps of screening removed studies of a low evidence quality and animal studies......On a global scale, myopia is one of the most common causes of visual impairment. Given the increasing prevalence of myopia, it is vital to understand the pathogenesis and to identify potential interventions. Some studies have described physical activity as a potential correlation for myopia....... Studies included had refractive error and physical activity (as measured by questionnaires, accelerometers and cycle ergometers) as separate, well-defined outcomes. Nine studies (six cross-sectional, two cohorts and one case-control study) with a total of 17 634 subjects were included. Six studies...

    The principal activities in the fields of solid-state physics (neutron scattering), plasma physics and meteorology are presented in this report that covers the period 1 January to 31 December 1976. In addition, research on nuclear spectroscopy was carried out up until March 31, 1976. The experimental and theoretical work in solid-state physics is roughly divided into the following main subject fields: investigations of the dynamic and static properties of magnetic and superconducting solids; studies of various kinds of phase transitions in magnetic and molecular systems; and investigations of the dynamic and static properties of molecular crystals and adsorbed monolayers. The main object of basic research in plasma physics is to investigate waves and instabilities in a relatively cold steady state plasma (produced in a Q-machine). Turbulence, ion cyclotron waves, and ion-acoustic waves in the presence of electron plasma waves are the chief phenomena investigated. Work on nuclear spectroscopy was concentrated on problems relating to fission. The meteorology section is primarily engaged in studies of the planetary boundary layer. (B.R.H.)

    2016-01-01

    We have made significant progress in ICF implosion performance on NIF since the 2011 IFSA. Employing a 3-shock, high adiabat CH (“High-Foot”) design, total neutron yields have increased 10-fold to 6.3 x10 15 (a yield of ∼ 17 kJ, which is greater than the energy invested in the DT fuel ∼ 12kJ). At that level, the yield from alpha self-heating is essentially equivalent to the compression yield, indicating that we are close to the alpha self-heating regime. Low adiabat, 4-shock High Density Carbon (HDC) capsules have been imploded in conventional gas-filled hohlraums, and employing a 6 ns, 2-shock pulse, HDC capsules were imploded in near-vacuum hohlraums with overall coupling ∼ 98%. Both the 4- and 2-shock HDC capsules had very low mix and high yield over simulated performance. Rugby holraums have demonstrated uniform x-ray drive with minimal Cross Beam Energy Transfer (CBET), and we have made good progress in measuring and modelling growth of ablation front hydro instabilities.

    Studies are reported of several aspects of the purely gluonic sector of QCD, including methods for efficiently generating gauge configurations, properties of the standard Wilson action and improved actions, and properties of the pure glue theory itself. Simulation of quantum chromodynamics in the ''quenched approximation'', in which the back reaction of quarks upon gauge fields is neglected, is studied with fermions introduced on the lattice via both Wilson and staggered formulations. Efforts are also reported to compute QCD matrix elements and to simulate QCD theory beyond the quenched approximation considering the effect of the quarks on the gauge fields. Work is in progress toward improving the algorithms used to generate the gauge field configurations and to compute the quark propagators. Implementation of lattice QCD on a hypercube is also reported

    CARROLL,J.

    1999-09-10

    The RIKEN-BNL center workshop on ''Hard parton physics in high energy nuclear collisions'' was held at BNL from March 1st-5th! 1999. The focus of the workshop was on hard probes of nucleus-nucleus collisions that will be measured at RHIC with the PHENIX and STAR detectors. There were about 45 speakers and over 70 registered participants at the workshop, with roughly a quarter of the speakers from overseas. About 60% of the talks were theory talks. A nice overview of theory for RHIC was provided by George Sterman. The theoretical talks were on a wide range of topics in QCD which can be classified under the following: (a) energy loss and the Landau-Pomeranchuk-Migdal effect; (b) minijet production and equilibration; (c) small x physics and initial conditions; (d) nuclear parton distributions and shadowing; (e) spin physics; (f) photon, di-lepton, and charm production; and (g) hadronization, and simulations of high pt physics in event generators. Several of the experimental talks discussed the capabilities of the PHENIX and STAR detectors at RHIC in measuring high pt particles in heavy ion collisions. In general, these talks were included in the relevant theory sessions. A session was set aside to discuss the spin program at RHIC with polarized proton beams. In addition, there were speakers from 08, HERA, the fixed target experiments at Fermilab, and the CERN fixed target Pb+Pb program, who provided additional perspective on a range of issues of relevance to RHIC; from jets at the Tevatron, to saturation of parton distributions at HERA, and recent puzzling data on direct photon production in fixed target experiments, among others.

    Relativistic heavy ion collisions at the LHC will uncover properties of hot and dense medium formed at collision energy thirty times larger than energy presently available at RHIC. ATLAS is one of three experiments participating in the heavy ion program at the LHC. A brief overview of variety of observables which will be measured by ATLAS to study soft and hard QCD phenomena in heavy ion environment is presented. In particular the detector will measure global observables like charged particle multiplicity, azimuthal anisotropy and energy flow. The detector provides also an excellent capability to probe the quark gluon plasma by measurement of high energy jets and photons as well as quarkonia states. Performance of a high granularity calorimeter, silicon tracking detector and muon spectrometer in heavy ion collisions is reported. A unique ATLAS potential to study Pb+Pb interactions is discussed.

    The University of Texas at Dallas (UTD) is participating in two e + e - , experiments, Beijing Spectrometer (BES) and BABAR, the PEP-11 B Factory detector. The UTD group consists of Profs. Joseph M. Izen and Xinchou Lou, seven Ph.D. students. A post-doc is requested to join them in this work. BES explores the physics of the τ-charm threshold region. Associated production of τ and charmed mesons allow for absolute branching fraction measurements with good control of backgrounds. BES is uniquely positioned to study the leptonic and hadronic decays of quarkonia. The Beijing Electron Positron Collider (BEPC) delivers luminosities an order of magnitude higher than earlier facilities. BES and BEPC will be upgraded following the 1994-5 run, and will resume data taking in Fall, 1996 with an improved detector and a Three-fold increase in luminosity. The raison d'etre of BABAR is the exploration of CP violation in the B meson system. An asymmetric storage ring is required to observe the time-dependence of the CP asymmetry. Other BABAR physics includes measurements of CKM matrix elements, rare B decays, penguin diagrams, B s decays, and precision measurements of τ and D meson decays. The scheduled BABAR turn-on in 1999 provides the UTD group with a natural evolution with continuous physics during this period. Professors Joseph M. Izen and Xinchou Lou are leading the BES and BABAR program at UTD. Both have specialized in e + e - collider experiments and share 22 years of experience at the SPEAR, BEPC, CESR, PETRA, SLC and LEP rings

    1993-09-01

    The research programs of the UCLA Particle and Nuclear Physics Research Group, the research objectives, results of experiments, the continuing activities and new initiatives are presented. The primary goal of the research is to test the symmetries and invariances of particle/nuclear physics with special emphasis on investigating charge symmetry, isospin invariance, charge conjugation, and CP. Another important part of our work is baryon spectroscopy, which is the determination of the properties (mass, width, decay modes, etc.) of particles and resonances. We also measure some basic properties of light nuclei, for example the hadronic radii of 3 H and 3 He. Special attention is given to the eta meson, its production using photons, electrons, π ± , and protons, and its rare and not-so-rare decays. In Section 1, the physics motivation of our research is outlined. Section 2 provides a summary of the research projects. The status of each program is given in Section 3. We discuss the various experimental techniques used, the results obtained, and we outline the plans for the continuing and the new research. Details are presented of new research that is made possible by the use of the Crystal Ball Detector, a highly segmented NaI calorimeter and spectrometer with nearly 4π acceptance (it was built and used at SLAC and is to be moved to BNL). The appendix contains an update of the bibliography, conference participation, and group memos; it also indicates our share in the organization of conferences, and gives a listing of the colloquia and seminars presented by us

  15. Transfer, loss and physical processing of water in hit-and-run collisions of planetary embryos

    Science.gov (United States)

    Burger, C.; Maindl, T. I.; Schäfer, C. M.

    2018-01-01

    Collisions between large, similar-sized bodies are believed to shape the final characteristics and composition of terrestrial planets. Their inventories of volatiles such as water are either delivered or at least significantly modified by such events. Besides the transition from accretion to erosion with increasing impact velocity, similar-sized collisions can also result in hit-and-run outcomes for sufficiently oblique impact angles and large enough projectile-to-target mass ratios. We study volatile transfer and loss focusing on hit-and-run encounters by means of smooth particle hydrodynamics simulations, including all main parameters: impact velocity, impact angle, mass ratio and also the total colliding mass. We find a broad range of overall water losses, up to 75% in the most energetic hit-and-run events, and confirm the much more severe consequences for the smaller body also for stripping of volatile layers. Transfer of water between projectile and target inventories is found to be mostly rather inefficient, and final water contents are dominated by pre-collision inventories reduced by impact losses, for similar pre-collision water mass fractions. Comparison with our numerical results shows that current collision outcome models are not accurate enough to reliably predict these composition changes in hit-and-run events. To also account for non-mechanical losses, we estimate the amount of collisionally vaporized water over a broad range of masses and find that these contributions are particularly important in collisions of ˜ Mars-sized bodies, with sufficiently high impact energies, but still relatively low gravity. Our results clearly indicate that the cumulative effect of several (hit-and-run) collisions can efficiently strip protoplanets of their volatile layers, especially the smaller body, as it might be common, e.g., for Earth-mass planets in systems with Super-Earths. An accurate model for stripping of volatiles that can be included in future planet

    In a very short time a proton microprobe and its associated beam scanning systems have been developed. Further improvements are necessary but a very useful facility should be available in the coming year. A research contract on 'depth profiling employing nuclear techniques' has been awarded to a group in the Physics Department of Victoria University of Wellington. This should strengthen the links between the nuclear physics groups at the University and the Institute. Discussions with anthropologists from Auckland and Otago Universities have revealed two areas where the Group could provide useful assistance - firstly in the development of cheap transportable X-ray fluoresence apparatus, and secondly the determination of hydration layers for obsidian dating. Work associated with both projects has been initiated. The accelerator has been used principally for the production of 11 C and 13 N. Interest is being shown by a number of groups in the 10 minute half-life nitrogen-13 isotope. Work on the nuclear magnetic relaxation times of various organs and the blood of mice at various stages during the development of cancer has been concluded and measurements have commenced on human blood samples, both normal and pathological

    Study of exotic new isotopes with the on-line isotope separator, ISOL, has begun. Quadrupole moments of isomeric states in lead isotopes have been further investigated. Progress is being made in identifying and overcoming certain insidious background processes in 14 C dating with the MP Tandem. The Fast Intense Neutron Source accelerator now operates well at 80% of design current. Development and construction of the Superconducting Cyclotron continues. Operation with larger plasma apertures has given improved beam quality and more beam current than expected from the duoPIGatron ion source. Commissioning of the Alvarez accelerator continues. The practicability of characterizing thick target spallation reactions in terms of ten activities from spallation and fast neutron fission multiplication has been demonstrated. Study of the temperature dependence of the condensate fraction in 4 He has been completed. A simple and very successful semiempirical relationship between the reduced superfluid density of liquid 4 He and the condensate fraction has been obtained. The source of copper impurities that are suspected to be limiting performance of CdTe detectors have been traced to the furnace wall materials; installation of platinum wall liners is planned. Refinement of programs for the simulation of chemical reactions continued. A number of improvements were made to the fuel defect experiment data processing system. Operations of the MP Tandem Accelerator and the main site computing centre are summarized. (OST)

    Kinemetic shifts have been measured in the β-delayed α-decay of 20 Na in order to deduce β-ν angular correlations. Analysis of the data is in progress. In a significant advance in techniques to measure quadrupole moments of isomeric states, the electric field gradient experienced by 147 Gd isomers was determined in a target of single-crystal gadolinium using Coulomb excitation. Commissioning of the Alvarez accelerator for the High Current Test Facility continues. The Alvarez tank has been cleaned, reasssembled with some modifications and subjected to initial steps of rf conditioning. A successful test was made of the radiation processing facility. A current of 6 mA was accelerated to 4 MeV and allowed to pass through a 0.75 mm stainless steel window into the fast-flowing cooling water. Conversion measurements were carried out with 19-element thorium and 7- and 37-element uranium targets. Preliminary data for distributions of characteristic radioactive products have been extracted for the 7-element target.

    1978-01-01

    The experiments reported provide detailed information on the fundamental nature of energy transfer processes in ion-molecule or atom-molecule collisions. By combining ion beam techniques with emission spectroscopy, data are obtained which directly lead to internal energy state distributions of atomic and molecular products of these collisions. Data are in the form of emission spectra from nascent energetically excited species formed in the energy transfer process. Changes in the collision-produced spectra as a function of beam kinetic energy yield information on the extent of energy conversion (kinetic → internal) in the collision process. Some of the specific energy transfer processes studied are applicable to the problem of achieving inverted energy level populations in high pressure gas lasers. Also discussed are experiments designed to test theoretical models which predict product energy partitioning in molecular collisions. Because experimentally determined energy state distributions deviate substantially from the predicted distributions it is concluded that additional theoretical work is needed. A simple model was developed which qualitatively reproduces the important features of the data. This model, which is considerably more general than those previously available is outlined and briefly discussed

    The Year 2000 problem poses major technical challenges to computer systems. For that reason it has drawn considerable attention over the past four years at the IAEA and within the international safeguards community of States and organisations. Actions of IAEA are very close to completion for the conversion of al related systems to make them Y2K compliant. As a result of IAEA past work and continuing liaison with Member States, the following needs were identified: organizing assistance and/or training to help states evaluate existing accounting software, and upgrade it or develop new Y2K compliant software; providing Y2K compliant software when needed; providing guidance and assistance on physical protection issues; organizing assistance missions visiting a state encountering problems; establishing contingency plans

    Several experiments are in progress to measure parity violation in strong interactions. The g-factors of eight high-spin isomeric states in four gadolinium isotopes have been added to the previously determined spin and parity data. Existing data on neutron-capture M1 γ-ray widths have been analyzed to deduce the position and spreading width of the M1 giant resonance in heavy nuclei. Solutions to long-standing differences between experimental and theoretical values for the thermal neutron capture cross sections of 1 H and 3 He are being sought in the framework of a more complete meson exchange theory. The standards group has submitted a value to the Bureau International des Poids et Mesures (BIPM) in a major international comparison of the measurement of the activity of 134 Cs. Development of the Fast Intense Neutron Source and the superconducting cyclotron continues. Preliminary design work is complete and component fabrication is underway for a preaccelerator suitable for accelerator breeder applications. Development is continuing on a multi-aperture duoPIGatron ion source with beam current and emittance suitable for a high current accelerator. In fertile-to-fissile conversion experiments at TRIUMF, the relative counting efficiencies of the β detectors used for proton beam monitoring and for neutron absorption rate measurement have been re-determined. Fusion studies included a preliminary study of anomalous energy loss mechanisms for high density relativistic electron beams ineracting with matter, and calculations to develop reliable neutronic evaluaton of fusion breeder blanket assemblies. Operations of the MP tandem accelerator and the main site computing facility are also summarized. (OST)

  11. Searching for new physics with three-particle correlations in $pp$ collisions at the LHC arXiv

    Sanchis-Lozano, Miguel-Angel

    New phenomena involving pseudorapidity and azimuthal correlations among final state particles in $pp$ collisions at the LHC can hint at the existence of hidden sectors beyond the Standard Model. In this paper we rely on a correlated-cluster picture of multiparticle production, which was shown to account for the ridge effect, to assess the effect of a hidden sector on three-particle correlations concluding that there is a potential signature of new physics that can be directly tested by experiments using well-known techniques.

    During the year a final paper was produced on XI* production from 2.9 GeV/c K - p interactions, and a paper on the Σ - π - π + (π 0 ) final state from 2.9 GeV/c K - d interactions is on the verge of completion. From our 14.75 GeV/c anti pp experiment results have been prepared for publication on three topics: the charm search, V 0 inclusive production, and π 0 production. Further analysis of data is continuing. In the 300 GeV/c pp experiment, investigations are completed or underway in three areas: neutral and charged pion correlations, inclusive γ and V 0 production, and inclusive resonance production. Further data on inclusive V 0 distributions from 6.5 GeV/c K - p interactions has been obtained and analysis is nearing completion. A good deal of effort went into the development of proposals for new physics. These new directions may be represented by three approved experiments at three different laboratories: Neutrino-deuterium interactions at Fermilab (an approved and a proposed experiment); Search for new states decaying into anti ΛΛ and K 0 /sub s/K 0 /sub s/ using the Multiparticle Spectrometer at B.N.L. (approved in May, 1977); Search for baryonium using the SLAC hybrid bubble chamber system, which won approval in September with a recommendation for prompt running from the Program Advisory Committee.

    Techniques for visualizing turbulent flow in nature and in the laboratory have evolved over half a millennium from Leonardo da Vinci's sketches of cascading waterfalls to the advanced imaging technologies which are now pervasive in our daily lives. Advancements in millimeter wave imaging have served to usher in a new era in plasma diagnostics, characterized by ever improving 2D, and even 3D, images of complex phenomena in tokamak and stellarator plasmas. Examples at the forefront of this revolution are electron cyclotron emission imaging (ECEI) and microwave imaging reflectometry (MIR). ECEI has proved to be a powerful tool as it has provided immediate physics results following successful diagnostic installations on TEXTOR, ASDEX-U, DIII-D, and KSTAR. Recent results from the MIR system on LHD are demonstrating that this technique has the potential for comparable impact in the diagnosis of electron density fluctuations. This has motivated a recent resurgence in MIR research and development, building on a prototype system demonstrated on TEXTOR, toward the realization of combined ECEI/MIR systems on DIII-D and KSTAR for simultaneous imaging of electron temperature and density fluctuations. The systems discussed raise the standard for fusion plasma diagnostics and present a powerful new capability for the validation of theoretical models and numerical simulations. (author)

    Fusion reactors are designed to operate at full power and generally at steady state. Yet experience shows the load variations, licensing constraints, and frequent sub-system failures often require a plant to operate at fractions of rated power. The aim of this study has been to assess the technology problems and design implications of startup and fractional power operation on fusion reactors. The focus of attention has been tandem mirror reactors (TMR) and we have concentrated on the plasma and blanket engineering for startup and fractional power operation. In this report, we first discuss overall problems of startup, shutdown and staged power operation and their influence on TMR design. We then present a detailed discussion of the plasma physics associated with TMR startup and various means of achieving staged power operation. We then turn to the issue of instrumentation and safety controls for fusion reactors. Finally we discuss the limits on transient power variations during startup and shutdown of Li 17 Pb 83 cooled blankets

    The nuclear physics group used the on-line isotope separator to make direct mass doublet measurments for the first time and to identify a new α-emitter, hafnium-162. A new NaI(Tl) detector gave improved data on the multiplicities and intensities of continuum γ-rays in gadolinium-147. Beam profile data for the Fast Intense Neutron source showed that tritium loss from bombarded targets is not caused by beam hot-spots. Geometry studies on the High Current Proton Accelerator showed that proton fraction increases with improved arc and gas efficiencies. In conjunction with fertile-to-fissile conversion experiments at TRIUMF, two types of monitoring foils agreed within 2.5% with results obtained by two other laboratories. Neutron diffraction data for a single β-N 2 crystal at 0.4 MPa showed that its scattering density distribution and mean translation displacements have almost perfect spherical symmetry. A new non-linear stress analysis code was marketed

    Last year's research program dealt with a large range of topics in high energy theoretical physics. Included in the problems studied were: flavor mixing angles in flavor gauge theory; grand unification schemes; neutral current phenomenology; charmonium decays; perturbative aspects of soft hadronic phenomena within the framework of the dual topological expansion; Regge trajectory slopes and the shape of the inclusive spectra; bound states in quantum electrodynamics; calculations of the Lamb Shift and hyperfine splitting in hydrogen (and muonium) through order α(Zα) 6 ; perturbation theory resummation techniques; collective behavior of instantons in quantum chromodynamics; 1/N expansion and mean field expansion techniques (applied to the nonlinear sigma model, classical solutions to Yang-Mills theories, and renormalized four-Fermi models of weak interactions); semiclassical calculation of Z 1 (α) in scalar QED; group theoretic studies of spontaneous symmetry breaking; fibre bundles applied to the topological aspects of gauge theories; strong-coupling expansions (as an aspect of infrared behavior, as a systematic perturbation expansion with reference to lattice extrapolation, applied to classical statistical mechanics, applied to problems with nonquadratic kinetic energy terms, and in transfer matrix formulations); eikonal methods (three-body Coulomb scattering, quark-antiquark potentials); computer augmented solutions to quantum field theory; topological excitations in two-dimensional models and WKB approximation on a lattice.

    1993-04-01

    This document summarizes the results of the studies on physics and detector at the proposed KEK B-factory made over the past one year. A considerable amount of studies were done prior to the last year on the Monte Carlo simulations of CP violating processes and an optimization of the detector for those processes [1,2]. These studies resulted in a conceptual design of the detector. Chapter 2 summarizes the configuration and expected performances of the proposed detector. Chapter 3 summarizes expected sensitivities of the detector to CP violation parameters. Chapter 4 describe mostly new results from our detector R and D effort. Status of the full simulation development is described in Chapter 5. What are the requirements on the momentum resolution and K/π separation for comprehensive studies of CP violation processes remain to be an unresolved issue. With a decision to use VENUS solenoid, we can obtain at most 1.0 Tesla. Even though all of our previous studies were done with this magnetic field and we have been convinced that 1.0 Tesla is adequate for measurements of most processes, we need to do these studies in conjunction with the other detectors such as K/π separation device. A good K/π separation above 1 GeV/c requires some types of Cherenkov counter. Construction of any of these devices is technically demanding and we need to examine its necessity carefully. This argument is given in Chapter 6. (J.P.N.) 72 refs

    The nuclear physics group obtained an accurate value of the gamow-teller contribution to the 2 + → 2 + (T=1) super allowed β transition in 20 Na from kinematic shifts in the β-delayed α-particle spectrum, thus allowing calculation of the Fermi coupling constant. In experiments with an anti-Compton NaI(Tl) shield, the average properties of the continuum γ-rays were determined for the (HI,xn) reaction and the properties of the high-energy (approximately 14 MeV) giant resonance γ-rays were correlated with specific (HI,xn) reaction channels. A systematic analysis by different techniques showed that recoil distance lifetime measurements can have systematic errors of about 10% from undetected feeding, background and/or hyperfine interactions. Average neutron kinetic energies for the 124 Sn ( 28 Si,5n) 147 Gd reaction correlated very strongly, but unexpectedly, with the bombarding energy. In the High Current Proton Accelerator, beamlet stacking was found to improve injection emittance by a factor of 1.9. The line-shapes of selected phonons in the orientationally disordered crystal β-nitrogen were calculated with the Michel-Nandts model. Computer simulation was used to calculate the spin-wave properties of the disordered ferromagnet Nisub(2)Mnsub(0.8)Vsub(0.2)Sn

    Highlights: ► Reaction progress in transesterification of soybean oil predicted using physical properties. ► Transesterification performed at 70 °C with Me/oil ratio 12:1 and 5 wt.% of BaO as catalyst. ► Viscosity and refractive index decreases nonlinearly during the progress of transesterification. ► Pour point increases linearly and cloud point increases nonlinearly during progress of reaction. ► Refractive index and pour point recommended for prediction transesterification progress. - Abstract: Biodiesel is a pure, non-toxic, biodegradable, clean-burning fuel and renewable alternative for fossil diesel fuel. In this work, a new method was introduced to determine reaction progress in transesterification of soybean oil to biodiesel by the use of physical property variation during reaction. Quantitative analysis stage for determination fatty acid methyl ester (FAME) which is expensive and time-consuming can be replaced by this method. To develop the method, in the first stage, transesterification of soybean oil at optimum conditions (70 °C with MeOH to oil molar ratio of 12:1 and 5 wt.% of BaO as catalyst) was carried out to determine how conversion and physical properties change with time. Then appropriate functions were fitted on the extracted data and were evaluated by comparison with GC results. Refractive index was selected as good physical property to predict reaction progress.

    Preparations are underway to use the intense electron beam produced by the Electron Test Accelerator for an experiment to test for violation of parity conservation in strong interactons. Using a capture γ-ray technique, the thermal neutron capture cross section of 90 Zr has been found to be significantly smaller than previous literature values. Commissioning of the Fast Intense Neutron Source to increase source strength has continued with some delay caused by the failure of the target rotating vacuum seal. The superconducting cyclotron program passed from full-scale test to construction phase. Design work is continuing and component fabrication has been started on a preaccelerator suitable for accelerator breeder applications. Development is continuing on a multi-aperture duoPIGatron ion source suitable for a high current accelerator. In fertile-to-fissile conversion experiments at TRIUMF, all of the neutron flux data taken previously at a proton energy of 480 MeV have been re-assessed. Experiments in solid state physics included (a) using small-angle scattering techniques for examination of detergent micelles in D 2 O solution, (b) the nature of phase transitions in two specimen antifluorites, (c) phonons in a large single crystal of deuterated ammonia, (d) vacancy formation energy in type 316 stainless steel by positron annihilation, (e) theoretical studies of the depth distribution of heavy-ion recoils. Possible improvements in the characteristics of CdTe detectors by introduction of hydrogen are being investigated. Operations of the MP Tandem accelerator and the main site computing facility are summarized. (OST)

    Primary emphasis is placed on understanding the nature of nucleon-nucleon and meson-nucleon interactions and on determining the consequences of such microscopic interactions in nuclear systems. We have constructed models of baryons which smoothly interpolate between currently popular bag and Skyrme models of hadrons and provide a vehicle for introducing the notions of quantum chromodynamics to low energy nuclear physics without violating the constraints of chiral invariance. Such models have been used to study the nucleon-nucleon interaction, the spectrum of baryons, and the important question of the radius of the quark bag. We have used many-body techniques to consider a variety of problems in finite nuclei and infinite many-body systems. New light has been shed on the nuclear coexistence of spherical and deformed states in the A = 18 region as well as the role of genuine three-body forces in this region. Phenomenological studies of infinite systems have led to a number of predictions particularly regarding the spin-polarized quantum liquids of current experimental interest. Microscopic many-body theories, based on the parquet diagrams, have been improved to a fully quantitative level for the ground state properties of infinite many-body systems. Finite temperature theories of nuclear matter, important in the study of heavy ion reactions, have been constructed. An expanded program in heavy ion theory has led to major advances in the multi-dimensional barrier penetration problem. Activities in nuclear astrophysics have provided a far more reliable description of the role of electron capture processes in stellar collapse. As a consequence, we have been able to perform legitimate calculations of the unshocked mass in Type II supernovae

    The main goals of this research are to develop and implement various techniques for describing molecular collision phenomena. The aim is to achieve sufficient understanding of these processes such that collision rates of interest (e.g., for gas lasers) may be reliably estimated. Several areas of research are being explored to achieve this goal. The specific molecular systems of H/sub 2/-H/sub 2/, HF-He, HF-Ar and HCl-Ar are being studied as examples of inelastic molecular collisions. In addition, during the past year further theoretical development was conducted in the area of decomposition techniques and effective Hamiltonian theory. Considerable progress was made in these various areas during the past year. This research represents a collaboration under this contract and with Professor R. Conn, University of Wisconsin, under contract AT(11-1)-2555. Much of the material in this report has been published or is presently in press (items indicated by * in the references).

The main program concerns fast neutron physics at the Van de Graaff laboratory with a strong emphasis on neutron scattering cross section data of elements of interest for reactor calculations. Since the Van de Graaff accelerator is still the one in Sweden giving the highest potential, it has been quite natural to use the machine also for some nuclear physics experiments with charged particles, though in some cases related to the neutron physics program. In connection with the use of the reactors at Studsvik for physics experiments, research programs have been in progress for several years concerning the use of reactor neutrons for production of isotopes for a systematic study of short lived nuclear isomeric states as well as for the study of the gamma emission in the fission process

    Full Text Available The discovery at RHIC of large high-pT suppression and flow of electrons from heavy quarks flavors have altered our view of the hot and dense matter formed in central Au + Au collisions at √sNN = 200 GeV. These results suggest a large energy loss and flow of heavy quarks in the hot, dense matter. In recent years, the RHIC experiments upgraded the detectors; (1 PHENIX Collaboration installed silicon vertex tracker (VTX at midrapidity region and forward silicon vertex tracker (FVTX at the forward rapidity region, and (2 STAR Collaboration installed the heavy flavor tracker (HFT and the muon telescope detector (MTD both at the mid-rapidity region. The PHENIX experiments established measurements of ψ (1S and ψ (2S production as a function of system size, p + p, p + Al, p + Au, and 3He + Au collisions at √sNN = 200 GeV. In p/3He + A collisions at forward rapidity, we observe no difference in the ψ (2S /ψ (1S ratio relative to p + p collisions. At backward rapidity, where the comoving particle density is higher, we find that the ψ (2S is preferentially suppressed by a factor of two. STAR Collaboration presents the first J/ ψ measurements in the di-muon decay channel in Au + Au at √sNN = 200 GeV at mid-rapidity. We observe a clear J/ψ RAA suppression and qualitatively well described by transport models, including dissociation and regeneration simultaneously.

    The progress of fast and thermal reactor physics, fusion neutronics and shielding researches in these twenty years can be clearly recognized in the reviews of reactor physics activities in Japan which had been perpared by the Special Committee on Reactor Physics: the joint committee under Atomic Energy Society of Japan and JAERI. Many topics of those discussed at the NEACRP meetings concerned fast reactor physics. Information exchange on the topics such as adjustment of group cross sections by integral data, central worth discrepancy, sodium void effect and heterogeneous core stimulated the researches in Japan. And achievements in Japan including those in the JAERI Fast Critical Facility FCA were reported and contributed largely to the international co-operation. In addition, the contribution from Japan was also made concerning a study of fusion blanket. Among various specialists' meetings recommended by NEACRP, those on nuclear data and benchmarks for reactor shielding were often held since 1973 and helpful to the progress of shielding researches in Japan. The Third Specialists' Meeting on Reactor Noise (SMORN-III) was held in Tokyo in 1981, indicating the recent progress in safety-related applications of reactor noise analysis. The NEACRP benchmark tests were quite useful to the progress of reactor physics in Japan, which included the benchmark calculations of BWR lattice cell, key parameters and burn-up characteristics of a large LMFBR, FBR and PWR shielding, and so on. It may be noted that the benchmark test on reactor noise analysis methods was successfully conducted by Japan in connection with SMORN-III. In addition, the co-operation was positively made to the compilation of light water lattice data, and the preparation of reviews on actinide production and burn-up, and blanket physics. (J.P.N.)

    Cancer progression is generally described in terms of accumulated genetic alterations and ensuing changes in cell properties. However, intermediary modifications are involved in the establishment of cancer cell phenotypes, at different levels of nuclear organization: DNA damages and their structural consequences, epigenetic modifications and their impact on chromatin architecture, changes in chromosome 3D organization. We review some of these alterations with a focus on their physical aspects. The challenge is to understand the multiscale interplay between generic physical mechanisms and specific biological factors in cancer cells. We argue that such an interdisciplinary perspective offers a novel viewpoint on cancer progression, early diagnosis and possibly therapeutic targets.

    This report presents the progress made in our continuing study of strongly correlated atomic systems for the last contract period. In the area of hyperspherical coordinates for Coulombic three-body systems of arbitrary masses a general computing code has been developed. Calculation of the adiabatic potential curves have been accomplished for the e/sup /minus//e + e/sup /minus// system of arbitrary L, S and parity π. It was found that these curves behave very similar to the potential curves of H/sup /minus// except for a mass scaling. We have also examined the mass dependence of the ground state potential curves for systems of three charged particles, AAB, and showed that the curves become more attractive as the mass m/sub A/ becomes larger than m/sub B/. For ion-atom collisions we have examined the transfer-excitation (TE) processes to establish the importance of electron correlations in these two-electron transitions. We have also examined the orientation parameters for excited states formed in collisions with positive and negative charged particles to establish the relation between the sign of the charge of the incident particles to the sign of

    The Indiana University High-Energy Physics Group has been actively involved in a variety of research programs during the current contract period. These programs are associated with major experiments conducted by our group at SLAC, Fermilab, Brookhaven and CERN. The physics areas under investigation include studies of psi meson production in hadron interactions (CERN WA-11), a study of low-p/sub t/ and high-p/sub t/ collisions utilizing the Multiparticle Spectrometer at Fermilab (E110/557/672), a glueball search (Brookhaven E771), and a high resolution study of e + e - interactions at high energy at SLAC (PEP HRS experiment). The status of the various efforts are discussed

  18. Preliminary Physics Summary: Deuteron and anti-deuteron production in pp collisions at $\\sqrt{s}=13$ TeV and in Pb–Pb collisions at $\\sqrt{s_{\\rm NN}}=5.02$ TeV

    CERN Document Server

    2017-01-01

    The mechanism which is behind the production of light (anti–)nuclei in ultra-relativistic collisions is one of the open questions in high-energy physics. We present the preliminary results obtained from the analyses of the (anti-)deuteron production for two different data samples collected in the LHC run 2: pp collisions at $\\sqrt{s}=13$ TeV and Pb–Pb collisions at $\\sqrt{s_{\\rm NN}}=5.02$ TeV. In particular, the production yields, the ratio between the production of anti-matter and matter, the d/p ratio and the coalescence parameter $B_2$ are compared for the two colliding systems and discussed in the context of thermal and coalescence models.

    We performed laboratory experiments colliding 0.8–1.0 mm and 1.0–1.6 mm SiO 2 dust aggregates with loosely bound centimeter-sized agglomerates of those aggregates in microgravity. This work builds on previous microgravity laboratory experiments examining the collisional properties of porous loosely bound dust aggregates. In centimeter-sized aggregates, surface forces dominate self-gravity and may play a large role in aggregate growth beyond this size range. We characterize the properties of protoplanetary aggregate analogs to help place constraints on initial formation mechanisms and environments. We determined several important physical characteristics of these aggregates in a large number of low-velocity collisions. We observed low coefficients of restitution and fragmentation thresholds near 1 m s −1 for 1–2 cm agglomerates, which are in good agreement with previous findings in the literature. We find the accretion efficiency for agglomerates of loosely bound aggregates to be higher than that for just aggregates themselves. We find sticking thresholds of 6.6 ± 2 cm s −1 , somewhat higher than those in similar studies, which have observed few aggregates stick at speeds of under 3 cm s −1 . Even with highly dissipative collisions, loosely bound agglomerates have difficulty accreting beyond centimeter-sized bodies at typical collision speeds in the disk. Our results indicate agglomerates of porous aggregates have slightly higher sticking thresholds than previously thought, allowing possible growth to decimeter-sized bodies if velocities are low enough.

    Experimental Program: assembly of an experiment as Fermilab E-531 to measure decay lifetimes, with tagged emulsion of charmed particles produced by high energy neutrinos was finished, and data taking now is in progress. An experiment to measure prompt neutrino production at Fermilab, E-613, was approved and detailed design of it is continuing. Search for parity violation in scattering of polarized protons, an experiment E-446-ZGS at ANL, was performed with the sensitivity of 10 -6 for detection of that process and yielded null results. Another run with improved sensitivity of 10 -7 is in preparation. Data analysis of the neutrino experiment E-310 at Fermilab will continue. Trimuon events, a new discovery, were identified in those data. Analysis of data on meson production from experiments performed at the ZGS--ANL, E-397, E-420 and E-428, with charged and neutral spectrometer will continue. A new relatively broad resonance (T approx. 70 MeV) with quantum numbers IJ/sup P/ = 00 -1 was discovered in the data from E-397. Analysis of beta decay of polarized Σ - hyperons is in progress. Participation in the design of the experimental areas for the Isabelle colliding proton beam accelerator will continue. Theoretical Program: topics of current interest in particle theory which will be investigated in the coming year are: the instanton-anti-instanton QCD gauge fields, discrete symmetries which may determine quark masses in the SU(2) x U(1) model, calculation of charmed meson production in e + e - collisions and formation of gluon jets, Higgs boson production in pp collisions, calculation of Higgs boson mass in terms of vector boson mass, study of Lagrangians with gauge and Higgs scalar fields, investigation of Faddeev--Popov determinants as related to quantum chromodynamics, a study of quantum flavor dynamics and anomalies in the axial vector Ward identity and a study of super symmetry as a part of a realistic model of leptonic interactions

    Under Hadrons in Nuclei and Nuclear Matter the authors research the ways in which the properties of nucleons and mesons are modified in the nuclear medium. Research progress is reported on a number of topics in this general area, including studies of the role of chiral symmetry for finite density or temperature nuclear matter, the use of QCD sum rules to describe baryons in nuclear matter, and color transparency. In the general field of Hadron Physics broad progress included studies of perturbative QCD, heavy quark physics, QCD sum rules, and QCD-based models. Notable progress was also achieved in Relativistic Dynamics in Quark, Hadron, and Nuclear Physics, where an explicit model of composite particles shows how the z-graph physics (which is an essential part of Dirac phenomenology) comes about. In addition, calculations of elastic electron-deuteron scattering based on two-body relativistic dynamics and meson exchange currents were completed, as were studies of quark-anti-quark bound states based on a relativistic quark model. Progress is also reported on the relativistic few-body problem. In the area of Heavy Ion Dynamics and Sharp Lepton Pairs, work continues on the Composite Particle Scenario for the 'Sharp Lepton Problem'. In particular, the scenario can now encompass the anomalous sharp leptons reported from positron irradiation of heavy neutral atoms, establishing such irradiations as an alternative experimental window to the heavy ion experiments

The high power CO 2 laser beam was used to irradiate Zr-N6 pressure tube samples. The aim was to assess surface modifications particularly from shock hardening. Application of radiofrequency waves were used to investigate the properties of relevant materials, notably industrial ferrites. Chalk River participated in an international collaboration on measurement of dielectric properties of materials at high temperatures. A second topical review on neutron scattering and mineral physics deals with phase transitions in carbonate and in silicates. Dualspec is operating successfully.

  2. Study of heavy ion collisions at Fermi energy: is the methodology orientating our understanding of physics?

    International Nuclear Information System (INIS)

    Bacri, Ch.O.

    2001-07-01

    The analysis of the reaction products in the case of a multi-fragmentation reaction requires an efficient sorting of the experimental data. A collision, detected in a 4π detector generates about 100 parameters that are measured. Experimental data have to be reduced to the part most meaningful of the studied event. A model of the reaction is necessary to discard or value variables on which the sorting could be based. The selection of experimental data implies almost always the introduction of a bias that is necessary to know in order to continue a thorough analysis of the experimental results. A theoretical work is then necessary not only in the view of the comparison between results and predictions but also to validate the assumptions that have been made to sort out the experimental data. This method is applied to the study of the nuclear reaction: Gd + U at 36 MeV/U. (A.C.)

    The reports from the three branches in Physics Division, Accelerator Physics, Neutron and Solid State Physics and Theoretical Physics, are each presented in separate sections. Each section features a topical review, highlighting in this report the use of high-temperature rf and microwave response of materials, magnetic excitations in hexagonal ABX 3 materials, and meson exchange currents in nuclear beta decay. Noteworthy achievements in the Accelerator Physics program include the successful operation to design energy of the re-vaned RFQ1 accelerator enabling now an energy of 1250 keV. The ECR ion source has operated for greater than 75 hours without failure and has produced the 100 mA needed for the RFQ1 accelerator. The neutron scattering program was again hampered by the NRU Reactor being down for repair. The good news is that the reactor was brought back up to full power in December thus enabling experiments to begin again. Experiments earlier in the year were carried out at Oak Ridge (US), Riso (Denmark), National Institute for Standards and Technology (US) and the Rutherford-Appleton Laboratory (UK). A new high capacity, portable pumping system was commissioned replacing a fixed one that had become obsolete and allowing now greater use of environment control devices on all spectrometers. An analysis of double-charge exchange reactions in nuclei has been used to provide limits on the radius of the neutron halo in 11 Li. The most up-to-date, complete and accurate tables of neutron scattering lengths and cross-sections have been completed. Continuous quality improvement (CQI) analyses were initiated for all the activities in Physics Division with the goal to enhance performance and provide better service to our many customers

    The high energy physics program at the University of Minnesota is reviewed. The Soudan 1 baryon decay experiment was converted from a concept demonstrated by a small prototype into a working experiment, which has already yielded interesting data about underground cosmic ray events. Fermilab E-629 acquired data on direct photon production in pion-nucleus and proton-nucleus collisions. Preliminary analysis of that experiment indicates a signal for direct photon events at transverse momenta as large as 4 GeV/c. The hyperon program continued its very fruitful studies of both the mechanisms for inclusive hyperon polarization and precision measurements of the hyperon magnetic moments with analyses of data from both Fermilab and Brookhaven experiments

  8. SU-E-T-64: CG-Based Radiation Therapy Simulator with Physical Modeling for Avoidance of Collisions Between Gantry and Couch Or Patient

    Yamanouchi, M; Arimura, H; Yuda, I

    2014-01-01

    Purpose: It is time-consuming and might cause re-planning to check couch-gantry and patient-gantry collisions on a radiotherapy machine when using couch rotations for non-coplanar beam angles. The aim of this study was to develop a computer-graphics (CG)-based radiation therapy simulator with physical modeling for avoidance of collisions between gantry and couch or patient on a radiotherapy machine. Methods: The radiation therapy simulator was three-dimensionally constructed including a radiotherapy machine (Clinac iX, Varian Medical Systems), couch, and radiation treatment room according to their designs by using a physical-modeling-based computer graphics software (Blender, free and open-source). Each patient was modeled by applying a surface rendering technique to their planning computed tomography (CT) images acquired from 16-slice CT scanner (BrightSpeed, GE Healthcare). Immobilization devices for patients were scanned by the CT equipment, and were rendered as the patient planning CT images. The errors in the collision angle of the gantry with the couch or patient between gold standards and the estimated values were obtained by fixing the gantry angle for the evaluation of the proposed simulator. Results: The average error of estimated collision angles to the couch head side was -8.5% for gantry angles of 60 to 135 degree, and -5.5% for gantry angles of 225 to 300 degree. Moreover, the average error of estimated collision angles to the couch foot side was -1.1% for gantry angles of 60 to 135 degree, and 1.4% for gantry angles of 225 to 300 degree. Conclusion: The CG-based radiation therapy simulator could make it possible to estimate the collision angle between gantry and couch or patient on the radiotherapy machine without verifying the collision angles in the radiation treatment room

    Correlations between x-ray emission and charge-changing interactions have been measured for high charged ions (16 ≤ Z ≤ 23) in the energy range of 0.1 to 10 MeV/u incident on gas targets under single collision conditions. These experiments combined with theoretical studies have established the existence of resonant transfer and excitation (RTE) and indicated a close relationship between RTE and dielectronic recombination. Detailed investigations of RTE include: (1) the projectile Z dependence; (2) the projectile charge-state dependence; (3) the effect of the target electron momentum distribution; and (4) observations of RTE involving L-shell excitation. These measurements are in reasonable agreement with theoretical calculations. Evidence for non-resonant transfer and excitation has been obtained from studies of 15 to 200 MeV S 13+ + He collisions. Single-electron capture and loss were measured for 2.5 to 200 MeV S 13+ + He thereby providing a comparison with theory over a very wide energy range. For single capture in Ca/sup 16,17,18,19 + + H 2 a significant contribution due to RTE was observed for energies where RTE is important. Cross sections for double-electron capture for S 13+ + He and Ne and Ar 15+ + Ne were found to be 1 to 2 orders of magnitude smaller than the corresponding single-capture cross sections. Target ionization associated with projectile charge exchange has been measured for 0.5 to 1.5 MeV/u O/sup 5,6,7,8 + + He and H 2 . 26 refs., 13 figs

    The work described herein is part of a project involving the study of low energy (< 10 MeV/A), intermediate energy (10--100 MeV/A) and relativistic (> 250 MeV/A) heavy ion reactions. In the low energy regime, we published a monograph on the properties of the heaviest elements and used that publication as a basis for making a set of ``best`` semi-empirical predictions of heavy element decay properties. The intermediate energy research effort focussed upon the completion of studies already begun and the initiation of a number of new experiments. In our study of a interaction of 21 MeV/nucleon {sup 129}Xe with {sup 197}Au, we compared the characteristics of the observed deep inelastic phenomena with various models of dissipative reactions and found significant discrepancies between observations and predictions. These discrepancies seemed to be caused by an improper treatment of pre-equilibrium in the early stages of the collision. In our study of the relativistic interaction of 400 MeV/nucleon {sup 12}C with {sup 197}Au, we reported the first direct physical measurement of the properties of the spallation residues from a nucleus-nucleus collision. We found the residue energies to be much lower than those predicted by the intranuclear cascade model, indicating some substantial modifications of that model are needed. But, we also found, indications of significant, non-zero values of the residue transverse momentum, a finding that calls into question the interpretation of a number of radiochemical recoil studies of the kinematics of high energy reactions. A program of performing numerical simulations of intermediate and high energy nuclear collisions using the QMD model was initiated.

    Satellite collision debris poses risks to existing space assets and future space missions. Predictive models of debris generated from these hypervelocity collisions are critical for developing accurate space situational awareness tools and effective mitigation strategies. Hypervelocity collisions involve complex phenomenon that spans several time- and length-scales. We have developed a satellite collision debris modeling approach consisting of a Lagrangian hydrocode enriched with smooth particle hydrodynamics (SPH), advanced material failure models, detailed satellite mesh models, and massively parallel computers. These computational studies enable us to investigate the influence of satellite center-of-mass (CM) overlap and orientation, relative velocity, and material composition on the size, velocity, and material type distributions of collision debris. We have applied our debris modeling capability to the recent Iridium 33-Cosmos 2251 collision event. While the relative velocity was well understood in this event, the degree of satellite CM overlap and orientation was ill-defined. In our simulations, we varied the collision CM overlap and orientation of the satellites from nearly maximum overlap to partial overlap on the outermost extents of the satellites (i.e, solar panels and gravity boom). As expected, we found that with increased satellite overlap, the overall debris cloud mass and momentum (transfer) increases, the average debris size decreases, and the debris velocity increases. The largest predicted debris can also provide insight into which satellite components were further removed from the impact location. A significant fraction of the momentum transfer is imparted to the smallest debris (< 1-5mm, dependent on mesh resolution), especially in large CM overlap simulations. While the inclusion of the smallest debris is critical to enforcing mass and momentum conservation in hydrocode simulations, there seems to be relatively little interest in their

    The Large Hadron Collider at CERN will collide lead ions at √ SNN = 5:5 TeV allowing high statistics studies of the dense partonic system with hard probes: heavy quarks and quarkonia with an emphasis on the b and ϒ, high-pT jets, photons, as well as Z0 bosons. The Compact Muon Solenoid (CMS) detectors will allow a wide range of unique measurements in nuclear collisions. The CMS data acquisition system, with its reliance on a multipurpose, high-level trigger system, is uniquely qualified for efficient triggering in high-multiplicity heavy ion events. The excellent calorimeters combined with tracking will allow detailed studies of jets, particularly medium effects on the jet fragmentation function and the energy and pT redistribution of particles within the jet. The large CMS acceptance will allow detailed studies of jet structure in rare γ − jet and Z-jet events. The high resolution tracker will tag b quark jets. The muon chambers combined with tracking will study production of the Z0 , J=ψ and the ϒ f...

    1991-05-01

    A completely new administrative structure of AECL Research was implemented on 1990 July 1. All of the basic physics programs, together with accelerator physics, radiation applications and most of the chemistry programs of AECL, have been placed in a new organizational unit called Physical Sciences. This unit also includes the management of the National Fusion Program. The research programs of Physical Sciences are grouped into three divisions: Chemistry, Physics and TASCC. Progress in each division will henceforth be reported on a twice-yearly basis. This report is the first of the new series to be issued by the TASCC Division. During the period covered by this report, the operation of the superconducting cyclotron has matured considerably, with over 30 accelerated ion beams more-or-less routinely available for a wide variety of nuclear physics experiments. The TASCC team, together with all the engineers, trades-people and other staff members who contributed to the design, constructed and commissioning of the Tandem Accelerator Superconducting Cyclotron facility, are to be heartily congratulated on bringing it to its present highly successful state in an unusually short period of time. In conjunction with our many outside collaborators, we are now engaged on exciting experiments in several areas of nuclear physics research, as reported in the following pages. We are well on the way to the establishment of a truly National Centre for Nuclear Physics research in Canada

    The brain reserve hypothesis links larger maximal lifetime brain growth (MLBG, estimated with intracranial volume [ICV]) with lower risk for cognitive decline/dementia. We examined whether larger MLBG is also linked to less physical disability progression over 5 years in a prospective sample of treatment-naive patients with multiple sclerosis (MS). Physical disability was measured with the Expanded Disability Status Scale (EDSS) at baseline and 5-year follow-up in 52 treatment-naive Serbian patients with MS. MRI measured disease burden (cerebral atrophy, T2 lesion volume) and MLBG: a genetically determined, premorbid (established during adolescence, stable thereafter) patient characteristic estimated with ICV (adjusted for sex). Logistic regression tested whether MLBG (smaller vs larger) predicts disability progression (stable vs worsened) independently of disease burden. Disability progression was observed in 29 (55.8%) patients. Larger MLBG predicted lower risk for progression (odds ratio 0.13, 95% confidence interval 0.02-0.78), independently of disease burden. We also calculated absolute change in EDSS scores, and observed that patients with smaller MLBG showed worse EDSS change (0.91 ± 0.71) than patients with larger MLBG (0.42 ± 0.87). Larger MLBG was linked to lower risk for disability progression in patients with MS over 5 years, which is the first extension of the brain reserve hypothesis to physical disability. MLBG (ICV) represents a clinically available metric that may help gauge risk for future disability in patients with MS, which may advance the science and practice of early intervention. Potential avenues for future research are discussed. © 2016 American Academy of Neurology.

    Progress in overcoming the difficulties encountered in commissioning the superconducting cyclotron, particularly those associated with the π-mode and beam extraction, has been greatly accelerated, largely as a result of the establishment of a TASCC Beam Commissioning Group to give focus and coordination to the work. The '8π spectrometer', which is jointly owned and operated at TASCC by AECL and the Universities of Montreal and McMaster, was relocated during the shutdown and has been producing exciting information on a new type of nucleus-one that has approximately the shape of a football, and is called 'superdeformed'. The physicists working at Chalk River have found the key to making superdeformed nuclei and have already discovered two of their own: 149 Gd and 153 Dy. A very fine Recoil Doppler apparatus has been constructed and used inside the gamma ball, and a CsI(Tl) miniball is being constructed to do particle measurements with large solid angle, also inside the large ball. In cooperation with scientists from Reactor Development, a new way to identify and measure hydrogen diffusion in Zr(2.5% Nb), the alloy used in CANDU pressure tubes, has been identified and is being developed. It makes use of the superconductivity of zirconium-niobium alloys in the beta phase

  13. Experimental program to study the physical vacuum: high-energy nucleus-nucleus collisions

    Quarks and gluons exist; they are nearly massless, but it is very hard or even impossible to knock them out of the proton. It is now widely believed that this strange state of affairs is due to the properties of the physical vacuum state as it now exists in our part of the Universe. On this view, the ground state of the vacuum is not that familiar in quantum electrodynamics (QED). That state is basically empty space, perturbed by fluctuations which occasionally give rise to a virtual electron-positron pair. In the quantum chromodynamic (QCD) theory of quarks and gluons, the stronger and more complicated forces give rise to a state which cannot be described as a perturbation on empty space. Instead, the physical vacuum has properties which resemble those of a physical medium. For example, the color field is completely excluded, or at least strongly repelled, from a macroscopic volume of physical vacuum. This effect confines the quarks and gluons which carry color, inside the hadrons. On the scale of hadrons, quantum fluctuations make the phenomena more complex, but a simple picture postulates that the strong color fields inside the hadron create a local volume of space more like the perturbative vacuum state, reverting to the physical vacuum state outside. This concept has been quantitatively expressed by the bag model, with some success. It seems that the physical vacuum has acquired properties reminiscent of Maxwell's ether. At least, so we are asked to believe. Maxwell introduced his ether for plausible reasons, but crucial experimental tests were found, and the theory was found wanting. In this talk, experiments for testing the idea that the physical vacuum is not identical to the perturbative one are discussed

    The authors have searched for new physics beyond the Standard Model of elementary particle physics in dielectron decay mode at the CDF (Collider Detector at Fermilab) experiment in {bar p}p collisions at √s = 1.96 TeV. The data were collected during the 2002-2003 runs corresponding to an integrated luminosity of 200 pb-1. Many extensions of the Standard Model have been proposed. Grand Unified Theories (GUT) assumes a larger gauge symmetry group and predict new gauge bosons. GUT has hierarchy problem in it and there have been many attempts to solve the hierarchy problem. Solutions for the hierarchy problem are supersymmetry, technicolor, large extra dimensions, warped extra dimensions and little Higgs models. The authors analyze the differential distribution of dielectron events in terms of their invariant mass and no significant excess is found in very high mass region. They present a 95% confidence level limit on the production cross section times branching ratio for new resonant particles decaying into an electron pair as a function of invariant mass. New resonant particles include new neutral gauge boson Z', Randall-Sundrum graviton, R-parity violating sneutrino, and technicolor particles. They also present limits on the effective Planck scale of large extra dimensions.

    1981-03-01

    During the past year, work on x-ray emission in heavy-ion collisions has concentrated on the following topics: environmental influences on the Kα x-ray spectra of 65-MeV sulfur ions traveling in solids; multiplet structure of few-electron sulfur ions; multiplet structure of Mg Kα x-ray satellites; polarization of 1s2p→1s 2 transitions in He-like sulfur ions; and interatomic electron transfer in ionic fluorine compounds following 1s2p vacancy production. Among the most significant accomplishments of the program was a study of the dependence of dynamic screening energy shifts on electron density. It was found that the shifts measured for the 2 1 P→1 1 S and 2 2 P→1 2 S x-ray transitions of He- and H-like sulfur ions (respectively) were in remarkably good agreement with theoretical expectations. Another interesting discovery evolved from measurements of fluorine Kα x-ray spectra for the alkali metal and alkaline earth fluorides using 5.5-MeV He + ions. The systematics of these spectra provide the first evidence for direct electron transfer between inner levels of neighboring atoms in a solid. 10 figures, 3 tables

    The ultimate goal of studying isospin physics via heavy-ion reactions with neutron-rich, stable and/or radioactive nuclei is to explore the isospin dependence of in-medium nuclear effective interactions and the equation of state of neutron-rich nuclear matter, particularly the isospin-dependent term in the equation of state, i.e., the density dependence of the symmetry energy. Because of its great importance for understanding many phenomena in both nuclear physics and astrophysics, the study of the density dependence of the nuclear symmetry energy has been the main focus of the intermediate-energy heavy-ion physics community during the last decade, and significant progress has been achieved both experimentally and theoretically. In particular, a number of phenomena or observables have been identified as sensitive probes to the density dependence of nuclear symmetry energy. Experimental studies have confirmed some of these interesting isospin-dependent effects and allowed us to constrain relatively stringently the symmetry energy at sub-saturation densities. The impact of this constrained density dependence of the symmetry energy on the properties of neutron stars have also been studied, and they were found to be very useful for the astrophysical community. With new opportunities provided by the various radioactive beam facilities being constructed around the world, the study of isospin physics is expected to remain one of the forefront research areas in nuclear physics. In this report, we review the major progress achieved during the last decade in isospin physics with heavy ion reactions and discuss future challenges to the most important issues in this field.

    1984-01-01

    The study of collision processes plays an important research role in modern physics. Many significant discoveries have been made by means of collision experiments. Based on theoretical, experimental, and computational studies, this volume presents an overview detailing the basic processes of electron-molecule collisions. The editors have collected papers-written by a group of international experts-that consider a diverse range of phenomena occurring in electronmolecule collisions. The volume discusses first the basic formulation for scattering problems and then gives an outline of the physics of electron-molecule collisions. The main topics covered are rotational transitions, vibrational transitions, dissociation of molecules in slow collisions, the electron-molecule collision as a spectroscopic tool for studying molecular electronic structures, and experimental and computational techniques for determining the cross sections. These well-referenced chapters are self-contained and can be read independently or consecutively. Authoritative and up-to-date, Electron-Molecule Collisions is a useful addition to the libraries of students and researchers in the fields of atomic, molecular, and chemical physics, and physical chemistry

    Physics of the inertial fusion is based on a variety of elements such as compressible hydrodynamics, radiation transport, non-ideal equation of state, non-LTE atomic process, and relativistic laser plasma interaction. In addition, implosion process is not in stationary state and fluid dynamics, energy transport and instabilities should be solved simultaneously. In order to study such complex physics, an integrated implosion code including all physics important in the implosion process should be developed. The details of physics elements should be studied and the resultant numerical modeling should be installed in the integrated code so that the implosion can be simulated with available computer within realistic CPU time. Therefore, this task can be basically separated into two parts. One is to integrate all physics elements into a code, which is strongly related to the development of hydrodynamic equation solver. We have developed 2-D integrated implosion code which solves mass, momentum, electron energy, ion energy, equation of states, laser ray-trace, laser absorption radiation, surface tracing and so on. The reasonable results in simulating Rayleigh-Taylor instability and cylindrical implosion are obtained using this code. The other is code development on each element physics and verification of these codes. We had progress in developing a nonlocal electron transport code and 2 and 3 dimension radiation hydrodynamic code. (author)

    One of the main challenges in nuclear and particle physics in the last 20 years has been to understand how the proton's spin is built up from its quark and gluon constituents. Quark models generally predict that about 60% of the proton's spin should be carried by the spin of the quarks inside, whereas high energy scattering experiments have shown that the quark spin contribution is small - only about 30%. This result has been the underlying motivation for about 1000 theoretical papers and a global program of dedicated spin experiments at BNL, CERN, DESY and Jefferson Laboratory to map the indi

    Internet connectivity is critical infrastructure for modern high energy nuclear and particle physics experiments at laboratories around the world. Achieving the ambitious computing goals is dependent on reliable and fast connections between collaborators in geographically separate regions. The ambitious computing goals of experiments such as BaBar, RHIC and the LHC place internet connectivity in a highly critical position. More over the ability to monitor performance and identify weak points for upgrades has become pivotal to recruiting collaborators not only overseas from the location of the experiment but in locations previously considered remote. The methodology of the Internet End-to-End Performance Monitoring (IEPM) project and long-term trends in regional and trans-oceanic performance measured by the PingER tools has previously been described. The project has grown significantly and now 593 nodes at 424 sites in 72 countries are monitored by 28 monitoring sites in 15 countries. A total of 2,138 end-to-end pairs are monitored, making PingER probably the largest performance monitoring project in the world. Recently particular effort has been made to extend the monitoring of locations in East Europe and the former USSR and to Central and South America and the Middle East, reflecting the increasing reach of high energy nuclear and particle physics research

    Fatigue is an exhaustion state caused by prolonged physical work and mental work, which can reduce working efficiency and even cause industrial accidents. Fatigue is a complex concept involving both physiological and psychological factors. Fatigue can cause a decline of concentration and work performance and induce chronic diseases. Prolonged fatigue may endanger life safety. In most of the scenarios, physical and mental workloads co-lead operator into fatigue state. Thus, it is very important to study the interaction influence and its neural mechanisms between physical and mental fatigues. This paper introduces recent progresses on the interaction effects and discusses some research challenges and future development directions. It is believed that mutual influence between physical fatigue and mental fatigue may occur in the central nervous system. Revealing the basal ganglia function and dopamine release may be important to explore the neural mechanisms between physical fatigue and mental fatigue. Future effort is to optimize fatigue models, to evaluate parameters and to explore the neural mechanisms so as to provide scientific basis and theoretical guidance for complex task designs and fatigue monitoring.

    Steady progress is reported towards the understanding of how to increase the number of fusions per muon and how to decrease the cost of muon production for muon. A better understanding of muon sticking and regeneration was reached, amplifying the physical significance of the observed anomalously high fusion yield. New fusion systems involving Z > 1 nuclei are explored and found to have an unexpectedly high potential fusion yield. Extensive numerical calculations of muon regeneration and Monte Carlo simulations of muon production have been performed. The problem of muon sticking in d-t fusion has been theoretically addressed and novel numerical approaches are being developed

    Purpose: Design a system to easily and securely track the progress of medical physics residents through their residency. Paper sign-offs while offering a real signature are not easily updated or summarized. A resident or mentor needs to be able to quickly assess what the current assignments are, what are overdue, and whether the resident is on track to complete all the tasks in a timely fashion. An electronic version can accomplish all these goals. Methods: An electronic dashboard was created in excel to not only house the tasks and sign-off but to succinctly summarize the residents progress. The first tab contains the dashboard which displays tables of the progress of the residents in each rotation, their current task, and overdue tasks. It also displays the last meetings with the residents, and timeline of important items, and a burn-down chart of the remaining tasks. This are all tied to the data and current date which auto fills the tables. The second tab contains the data. This is comprised of lists of rotations and their associated tasks along with their due dates. A signature column was also created which is password protected but allows special subset users i.e. mentors to alter without using a password. Results: The dashboard has allowed residents to better track their progress and tells them what they should be working on. It has also allowed the mentors and the program director to rapid assess their progress. Conclusion: The dashboard is successful and has been created to allow easy addition and subtraction of required tasks as the residency evolves. The next step is to create a web app version of the excel sheet with logins.

    The topic is presented in a series of slides organized as follows: MCATK overview, development strategy, available algorithms, problem modeling (sources, geometry, data, tallies), parallelism, miscellaneous tools/features, example MCATK application, recent areas of research, and summary and future work. MCATK is a C++ component-based Monte Carlo neutron-gamma transport software library with continuous energy neutron and photon transport. Designed to build specialized applications and to provide new functionality in existing general-purpose Monte Carlo codes like MCNP, it reads ACE formatted nuclear data generated by NJOY. The motivation behind MCATK was to reduce costs. MCATK physics involves continuous energy neutron & gamma transport with multi-temperature treatment, static eigenvalue (keff and α) algorithms, time-dependent algorithm, and fission chain algorithms. MCATK geometry includes mesh geometries and solid body geometries. MCATK provides verified, unit-test Monte Carlo components, flexibility in Monte Carlo application development, and numerous tools such as geometry and cross section plotters.

    A major project involving the study of electron transfer in fluorine compounds following multiple K-plus L-shell ionization by 5.5 MeV He, 22 MeV C, 48 MeV Mg, and 80 MeV Ar ions was completed. This comprehensive investigation, which began three years ago, uncovered a resonant electron transfer mechanism, provided the first quantitative estimates of electron transfer rates, and revealed the importance of fast electron transfer to n greater than or equal to 3 states in solid compounds. Considerable progress was made in delineating the effects of solid state environment on x-ray emission from highly stripped projectile ions. A surprising result in this project area was the discovery of lines associated with states involving n = 3 electrons in 48 MeV Mg projectile x-ray spectra obtained with thick carbon targets. Work was completed on a study of the alignment of foil-excited H- and He-like states in 65 MeV sulfur ions. These measurements are being extended to Magnesium ions with the intention of searching for surface and tilted foil effects. The report contains a summary of the research activities supported by this contract during the 1981 to 1982 contract year

    Discipline-based Education Research (DBER) is a research field richly combining a deep understanding of how to teach a particular discipline with an evolving understanding how people learn that discipline. At its center, DBER has an overarching goal of improving the teaching and learning of a discipline by focusing on understanding the underlying mental mechanisms learners use as they develop expertise. Geoscience Education Research, or GER, is a young but rapidly advancing field which is poised to make important contributions to the teaching and learning of earth and space science. Nascent geoscience education researchers could accelerate their community's progress by learning some of the lessons from the more mature field of Physics Education Research, PER. For the past three decades, the PER community has been on the cutting edge of DBER. PER started purely as an effort among traditionally trained physicists to overcome students' tenaciously held misconceptions about force, motion, and electricity. Over the years, PER has wrestled with the extent to which they included the faculty from the College of Education, the value placed on interpretive and qualitative research methods, the most appropriate involvement of professional societies, the nature of its PhD programs in the College of Science, and how to best disseminate the results of PER to the wider physics teaching community. Decades later, as a more fully mature field, PER still struggles with some of these aspects, but has learned important lessons in how its community progresses and evolves to be successful, valuable, and pertinent.

    The project of this progress report are all ultimately concerned with various aspects of numerical simulations of lattice gauge theories. These aspects include algorithms, machines, theoretical studies and actual simulations. We made progress in four general areas: studies of new algorithms, determination of the SU(3) β-function, studies of the finite temperature QCD phase transition in the presence of fermions, and the calculation of hadronic matrix elements. We will describe each of these in turn. 7 refs

    A study of events with missing transverse energy and an energetic jet is performed using pp collision data at a centre-of-mass energy of 7 TeV. The data were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 36 inverse picobarns. An excess of these events over standard model contributions is a signature of new physics such as large extra dimensions and unparticles. The number of observed events is in good agreement with the prediction of the standard model, and significant extension of the current limits on parameters of new physics benchmark models is achieved.

  17. Search for new physics with a monojet and missing transverse energy in pp collisions at √s = 7 TeV.

    A study of events with missing transverse energy and an energetic jet is performed using pp collision data at a center-of-mass energy of 7 TeV. The data were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb(-1). An excess of these events over standard model contributions is a signature of new physics such as large extra dimensions and unparticles. The number of observed events is in good agreement with the prediction of the standard model, and significant extension of the current limits on parameters of new physics benchmark models is achieved.

    Summarized in this report is the progress achieved during the period from November 1, 1994 to October 31, 1995. The experimental work described in this report is in electromagnetic and heavy-ion nuclear physics. The effort in electromagnetic nuclear physics is in preparation for the research program at the Continuous Electron Beam Accelerator Facility (CEBAF) and is focused on the construction and use of the CEBAF Large Acceptance Spectrometer (CLAS). The heavy-ion experiments were performed at the Argonne National Laboratory ATLAS facility and SUNY, Stony Brook. The physics interests driving these efforts at CEBAF are in the study of the structure, interactions, and nuclear-medium modifications of mesons and baryons. This year, an extension of the experiment to measure the magnetic form factor of the neutron was approved by the CEBAF Program Advisory Committee Nine (PAC9) for beam at 6 GeV. The authors also submitted updates to PAC9 on the experiments to measure inclusive η photoproduction in nuclei and electroproduction of the Λ, Λ*(1520), and f 0 (975). In addition to these experiments, the authors collaborated on a proposal to measure rare radiative decays of the φ meson which was also approved by PAC9. Their contributions to the construction of the CLAS include the development of the drift-chamber gas system, drift-chamber software, and controls software. Major has been leading the effort in the construction of the gas system. In the last year, the Hall B gas shed was constructed and the installation of the gas system components built at the University of Richmond has begun. Over the last six years, the efforts in low-energy heavy-ion physics have decreased due to the change in focus to electromagnetic nuclear physics at CEBAF. Most of the heavy-ion work is completed and there are now new experiments planned. Included in this report are two papers resulting from collaborations on heavy-ion experiments

    During the past year the CMU Medium Energy Physics Group has been involved in the running of three experiments. In addition, software and hardware for two new experiments scheduled to take place over the next few months have been developed. A new proposal, ''Search for a Strangeness -2 Dibaryon Using a 3 He Target,'' was submitted to the Brookhaven Program Advisory Committee and recently approved. In the spring of this year, studies of hypernuclear decay shifted to few body systems. Data on the decay of 5 /sub Λ/He was taken along with preliminary data on 4 /sub Λ/He. This was followed a month later by a run at LEAR to study anti ΛΛ production. The high statistics runs should allow extraction of the spin correlation coefficients not previously obtainable and also includes a detailed study at threshold. In December, a second run at LEAR began the start of anti ΛΣ production studies and tested the ability to measure K/sub s/K/sub s/ production; this channel will be used to search for the ξ(2230) in the summer of 1986. In preparation for the ξ(2230) search, extensive Monte Carlo simulations have been performed at CMU to aid in the design of the detector system. Data analysis routines from hyperon production studies were modified and the first K/sub s/K/sub s/ event was extracted from existing data. The CMU group has had extensive involvement in an experiment to search for strangeness production relativistic heavy ion collisions. Hardware to provide the online analysis and data storage facilities for the experiment has been purchased and developed. CMU personnel has also worked on the development of software with the flexibility required to monitor this complex experiment. 37 refs., 53 figs., 8 tabs

    During the past year the Carnegie Mellon University (CMU) Medium Energy Physics Group activities included five experimental programs, each at different stages of development. The analyses of data from two previous experiments were completed over the last year; a recent doctoral thesis represents a milestone in our study of the weak decays of hypernuclei. Software and hardware support was continued and data analysis initiated for the two experiments which received running time during this period. The status of the H dibaryon search proposals changed from conditional approval to full approval when funds were allocated for the new kaon beam line required for the experiments. The measurements of anti ΛΛ production at LEAR (PS-185) have been completed. A study of the polarization and angular distributions near threshold have been submitted for publication and an analysis of a CP test of the decay asymmetry parameters is complete. Results of data taken last year are being finalized. The analysis of data on the decay of 5 /sub Λ/He (AGS E-788) taken at BNL has also been completed in the past year and a publication is in preparation. Last summer the focus of the PS185 collaboration shifted from anti ΛΛ to a search for evidence of the ξ(2230) using the anti pp → K/sub s/K/sub s/ channel. Modifications designed to increase the acceptance of the LEAR anti ΛΛ experimental apparatus for this reaction were completed and a scan of the energy region near 2230 MeV took place in August. The data from this experiment are being analyzed at CMU. The CMU group has had extensive involvement in an experiment to search for strangeness production relativistic heavy ion collisions (CERN NA36). CMU personnel have installed computer hardware and worked on the development of new software designed for the on-line monitoring. The work was completed in time for the first running of the experiment in November of 1986

    The nuclear theory program deals with the properties of nuclei and with the reactions and interactions between nuclei and a variety of projectiles. The main areas of concentration are: heavy-ion direct reactions at nonrelativistic energies; nuclear shell theory and nuclear structure; nuclear matter and nuclear forces;intermediate-energy physics and pion-nucleus interactions; and high-energy collisions of heavy ions. Recent progress and plans for future work in these five main areas of concentration and a summary of other theoretical studies currently in progress or recently completed are presented

    The goals of this research are the experimental testing of fundamental theories of physics such as grand unification and the exploration of cosmic phenomena through the techniques of particle physics. We are currently engaged in construction of the MACRO detector, an Italian-American collaborative research instrument with a total particle acceptance of 12,000 m 2 sr, which will perform a sensitive search for magnetic monopoles using excitation-ionization methods. Other major objectives of the MACRO experiment are to search for astrophysical high energy neutrinos expected to be emitted by such objects as Vela X-1, LMC X-4 and SN-1987A and to search for low energy neutrino bursts from gravitational stellar collapse. The past year has seen major progress in our program of liquid scintillator development. We now have an advanced scintillator formulation whose figure-of-merit for use in long counters (such as the MACRO counters) is double that of the previous best scintillator. The new formulation promises to enhance substantially the physics potential of the MACRO detector. Dr. Charles Lane (Ph.D. 1987, Caltech)l has now joined our group, resulting in significant expansion of our responsibilities on the MACRO experiment. We are now leaders of the American effort to develop the off-line data analysis for MACRO

    About 90 percent of the research activities of the INFP in 1994 were devoted to superconductivity as the priority research field of the Institute. In the domain of fundamental research, the work on oxidic HT superconductors was continued, concentrating on the electronic structure and details of the lattice dynamics. New tasks were opened up with studies on the recently discovered boron nitrides of the type LnNi 2 B 2 C (Ln=Y,Lu,..) with superconducting transition temperatures of up to T c ∼23K. Good progress was achieved in the preparation of MPMG superconducting bulk specimens intended for use in self-stabilising magnetic bearings. A prototype flywheel power storage system was developed for demonstrating the technological feasibility. Application-oriented studies were concerned with the growth of epitactic thin films on application-relevant substrates and including suitable buffer layers, and with the examination of the high-frequency performance of these films. Fullerene research continued with studies into the solid-state physics of crystalline fullerenes or fullerene compounds, and the preparation and characterisation of endofullerenes such as La C 82 . The remaining approximately 10 percent of the Institute's research activities covered experimental and theoretical work on the physics of surfaces and boundary surfaces, and the physics of mesoscopic systems.

    A search for physics beyond the standard model involving events with one or more photons, jets, and missing transverse energy has been performed by the CMS experiment. The data sample corresponds to an integrated luminosity of 4.93 inverse femtobarns of proton-proton collisions at $\\sqrt{s}$ = 7 TeV, produced at the Large Hadron Collider. No excess of events with large missing transverse energy is observed beyond expectations from standard model processes, and upper limits on the signal production cross sections for new physics processes are set at the 95% confidence level. The results of this search are interpreted in the context of three models of new physics: a general model of gauge-mediated supersymmetry breaking, Simplified Models, and a theory involving universal extra dimensions. In the absence of evidence for new physics, exclusion regions are derived in the parameter spaces of the respective models.

    A search for physics beyond the standard model involving events with one or more photons, jets, and missing transverse energy has been performed by the CMS experiment. The data sample corresponds to an integrated luminosity of 4.93 fb-1 of proton-proton collisions at TeV, produced at the Large Hadron Collider. No excess of events with large missing transverse energy is observed beyond expectations from standard model processes, and upper limits on the signal production cross sections for new physics processes are set at the 95% confidence level. The results of this search are interpreted in the context of three models of new physics: a general model of gauge-mediated supersymmetry breaking, Simplified Models, and a theory involving universal extra dimensions. In the absence of evidence for new physics, exclusion regions are derived in the parameter spaces of the respective models.

    This is the Annual Progress Report of the theoretical particle theory group at the University of Florida under DoE Grant DE-FG05-86ER40272. At present our group consists of four Full Professors (Field, Ramond, Thorn, Sikivie) and three Assistant Professors (Qiu, Woodard, Kennedy). Dallas Kennedy recently joined our group increasing the Particle Theory faculty to seven. In addition, we have three postdoctoral research associates, an SSC fellow, and eight graduate students. The research of our group covers a broad range of topics in theoretical high energy physics with balance between theory and phenomenology. Included in this report is a summary of the last several years of operation of the group and an outline of our current research program.

    This progress report and continuation proposal summarizes our achievements for the period from July 1, 1994 to September 30, 1995 and requests continued funding for our program in experimental medium-energy nuclear physics. The focus of our program remains the understanding of the short-range part of the strong interaction in the nuclear medium. In the past year we have focused our attention ever more sharply on experiments with real tagged photons, and we have successfully defended two new experimental proposals: Photofission of Actinide and Preactinide Nuclei at SAL and Photoproduction of the ρ Meson from the Proton with Linearly Polarized Photons at CEBAF. (We are co-spokespersons on two previously approved Hall-B experiments at CEBAF, Photoreactions on 3 He and Photoabsorption and Photofission of Nuclei.) As part of the team that is instrumenting the Photon Tagger for Hall B; we report excellent progress on the focal-plane detector array that is being built at our Nuclear Detector Laboratory, as well as progress on our plans for instrumentation of a tagged polarized-photon beam using coherent bremsstrahlung. Also, we shall soon receive a large computer system (from the SSC) which will form the basis for our new Data Analysis Center, which, like the Nuclear Detector Laboratory, will be operated under the auspices of The George Washington University Center for Nuclear Studies. Finally, during the past year we have published six more papers on the results of our measurements of pion scattering at LAMPF and of electron scattering at NIKHEF and Bates, and we can report that nearly all of the remaining papers documenting this long series of measurements are in the pipeline

    The objective of this program is to measure atomic collision cross sections and equilibrium fractions of ions and atoms in metal vapor targets. The goal is to obtain experimental information on atomic collision processes relevant to the Magnetic Fusion Energy Program. In particular, in connection with the development of double charge exchange D - ion sources, we are measuring D - formation cross sections in alkaline-earth metal vapor targets. During the period covered in this report we have measured electron transfer cross sections for 3-40 keV D + ions and D 0 atoms in collision with calcium vapor

    Neurodegeneration is thought to be the major cause of ongoing, irreversible disability in progressive stages of multiple sclerosis. Gamma-aminobutyric acid is the principle inhibitory neurotransmitter in the brain. The aims of this study were to investigate if gamma-aminobutyric acid levels (i) are abnormal in patients with secondary progressive multiple sclerosis compared with healthy controls; and (ii) correlate with physical and cognitive performance in this patient population. Thirty patients with secondary progressive multiple sclerosis and 17 healthy control subjects underwent single-voxel MEGA-PRESS (MEscher-GArwood Point RESolved Spectroscopy) magnetic resonance spectroscopy at 3 T, to quantify gamma-aminobutyric acid levels in the prefrontal cortex, right hippocampus and left sensorimotor cortex. All subjects were assessed clinically and underwent a cognitive assessment. Multiple linear regression models were used to compare differences in gamma-aminobutyric acid concentrations between patients and controls adjusting for age, gender and tissue fractions within each spectroscopic voxel. Regression was used to examine the relationships between the cognitive function and physical disability scores specific for these regions with gamma-aminobuytric acid levels, adjusting for age, gender, and total N-acetyl-aspartate and glutamine-glutamate complex levels. When compared with controls, patients performed significantly worse on all motor and sensory tests, and were cognitively impaired in processing speed and verbal memory. Patients had significantly lower gamma-aminobutyric acid levels in the hippocampus (adjusted difference = −0.403 mM, 95% confidence intervals −0.792, −0.014, P = 0.043) and sensorimotor cortex (adjusted difference = −0.385 mM, 95% confidence intervals −0.667, −0.104, P = 0.009) compared with controls. In patients, reduced motor function in the right upper and lower limb was associated with lower gamma-aminobutyric acid

    Recent progress of theoretical charge transfer study in ion-molecule collisions at the intermediate energy is reviewed. Concept of close and distant collisions obtained from extensive ion-atom collision studies is identified so that it can be utilized to model two distinct collision processes. For a close collision, explicit representation of the whole collision complex is necessary to describe collision dynamics correctly, while a model potential approach for molecule is appropriate for a distant collision. It is shown that these two distinct models are indeed capable of reproducing experimental charge transfer cross sections. Some remarks for further theoretical study of ion-molecule collisions are also given. 21 refs., 8 figs

    This report summarizes experimental work carried out between October 1, 1990, the closing of our Progress Report, and August 14, 1991 at the Nuclear Physics Laboratory of the University of Colorado, Boulder, under contract DE-FG02-ER40269 with the United States Department of Energy. This contract supports broadly based experimental work in intermediate energy nuclear physics. The program includes pion-nucleon studies at TRIUMF and LAMPF, inelastic pion scattering and charge exchange reactions at LAMPF, and nucleon charge exchange at LAMPF/NTOF. The first results of spin-transfer observables in the isovector (rvec p,rvec n) reaction are included in this report. Our data confirm the tentative result from (rvec p,rvec p') reactions that the nuclear isovector spin response shows neither longitudinal enhancement nor transverse queching. Our program in quasifree scattering of high energy pions shows solid evidence of isoscalar enhancement of the nuclear nonspin response. We include several comparisons of the quasifree scattering of different probes. Results from our efforts in the design of accelerator RF cavities are also included in this report

    A growing number of reports eloquently speak about explorations into cardiac magnetic resonance (CMR) at ultrahigh magnetic fields (B0≥7.0 T). Realizing the progress, promises and challenges of ultrahigh field (UHF) CMR this perspective outlines current trends in enabling MR technology tailored for cardiac MR in the short wavelength regime. For this purpose many channel radiofrequency (RF) technology concepts are outlined. Basic principles of mapping and shimming of transmission fields including RF power deposition considerations are presented. Explorations motivated by the safe operation of UHF-CMR even in the presence of conductive implants are described together with the physics, numerical simulations and experiments, all of which detailing antenna effects and RF heating induced by intracoronary stents at 7.0 T. Early applications of CMR at 7.0 T and their clinical implications for explorations into cardiovascular diseases are explored including assessment of cardiac function, myocardial tissue characterization, MR angiography of large and small vessels as well as heteronuclear MR of the heart and the skin. A concluding section ventures a glance beyond the horizon and explores future directions. The goal here is not to be comprehensive but to inspire the biomedical and diagnostic imaging communities to throw further weight behind the solution of the many remaining unsolved problems and technical obstacles of UHF-CMR with the goal to transfer MR physics driven methodological advancements into extra clinical value.

    The ITER plasma control system has the same functional scope as the control systems in present tokamaks. These are plasma operation scenario sequencing, plasma basic control (magnetic and kinetic), plasma advanced control (control of RWMs, NTMs, ELMs, error fields, etc) and plasma fast shutdown. This chapter considers only plasma initiation and plasma basic control. This chapter describes the progress achieved in these areas in the tokamak experiments since the ITER Physics Basis (1999 Nucl. Fusion 39 2577) was written and the results of assessment of ITER to provide the plasma initiation and basic control. This assessment was done for the present ITER design (15 MA machine) at a more detailed level than it was done for the ITER design 1998 (21 MA machine) described in the ITER Physics Basis (1999 Nucl. Fusion 39 2577). The experiments on plasma initiation performed in DIII-D and JT-60U, as well as the theoretical studies performed for ITER, have demonstrated that, within specified assumptions on the plasma confinement and the impurity influx, ITER can produce plasma initiation in a low toroidal electric field (0.3 V m -1 ), if it is assisted by about 2 MW of ECRF heating. The plasma basic control includes control of the plasma current, position and shape-the plasma magnetic control, as well as control of other plasma global parameters or their profiles-the plasma performance control. The magnetic control is based on more reliable and simpler models of the control objects than those available at present for the plasma kinetic control. Moreover the real time diagnostics used for the magnetic control in many cases are more precise than those used for the kinetic control. Because of these reasons, the plasma magnetic control was developed for modern tokamaks and assessed for ITER better than the kinetic control. However, significant progress has been achieved in the plasma performance control during the last few years. Although the physics basis of plasma operation

    A search for new physics is performed using events with isolated same-sign leptons and at least two bottom-quark jets in the final state. Results are based on a sample of proton-proton collisions collected at a center-of-mass energy of 8 TeV with the CMS detector and corresponding to an integrated luminosity of 10.5 inverse femtobarns. No excess above the standard model background is observed. Upper limits are set on the number of events from non-standard-model sources and are used to constrain a number of new physics models. Information on acceptance and efficiencies is also provided so that the results can be used to confront an even broader class of new physics models.

    Cross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e+e- collisions at centre-of-mass energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results for e+e-, mu+mu-, tau+tau-, qq, bb and cc production are in agreement with the Standard Model predictions. Constraints are set on scenarios of new physics such as four-fermion contact interactions, leptoquarks, Z' bosons, TeV-scale quantum gravity and R-parity violating squarks and sneutrinos.

    The months that have passed since the last CMS Bulletin have been a very busy and exciting time for CMS physics. We have gone from observing the very first 8TeV collisions produced by the LHC to collecting a dataset of the collisions that already exceeds that recorded in all of 2011. All in just a few months! Meanwhile, the analysis of the 2011 dataset and publication of the subsequent results has continued. These results come from all the PAGs in CMS, including searches for the Higgs boson and other new phenomena, that have set the most stringent limits on an ever increasing number of models of physics beyond the Standard Model including dark matter, Supersymmetry, and TeV-scale gravity scenarios, top-quark physics where CMS has overtaken the Tevatron in the precision of some measurements, and bottom-quark physics where CMS made its first discovery of a new particle, the Ξ*0b baryon (candidate event pictured below).

    Topics in Atomic Collision Theory originated in a course of graduate lectures given at the University of Colorado and at University College in London. It is recommended for students in physics and related fields who are interested in the application of quantum scattering theory to low-energy atomic collision phenomena. No attention is given to the electromagnetic, nuclear, or elementary particle domains. The book is organized into three parts: static field scattering, electron-atom collisions, and atom-atom collisions. These are in the order of increasing physical complexity and hence necessar

  1. Daily goal progress is facilitated by spousal support and promotes psychological, physical, and relational well-being throughout adulthood

    In two daily-diary studies, we tested the consequences and precursors of daily goal progress throughout the adult lifespan. Attachment theory posits that exploration—including the pursuit of autonomous goals—promotes well-being across the lifespan and is facilitated by support from close others. For both young-adult newlyweds (Study 1) and married couples in late adulthood (Study 2), daily independent goal progress predicted same-day and next-day improvements in psychological, physical, and relational well-being. Specifically, when participants made more progress on their goals than usual on one day, they reported increases in positive affect, sleep quality, and relationship quality, and decreased physical symptoms, the following day (as well as concurrently). Additionally, spousal support (i.e., availability, encouragement, and noninterference) enabled same-day and next-day goal progress. Mediational analyses showed indirect links between spousal support and well-being through goal progress. Some effects were moderated by attachment orientation in the newlywed sample; individuals with greater insecure attachment benefited most from goal progress, and spousal support enabled goal progress most strongly for individuals with less anxious attachment. Overall, these results support and extend attachment theoretical propositions regarding the importance of the exploration system across the adult lifespan. They contribute to existing literature by demonstrating wide-ranging consequences of successful exploration for well-being and by providing evidence for the importance of both exploration and support for exploration into late adulthood.

    1988-03-01

    This report covers the fourth semi-annual period since the Research Company was reorganized. We now have eight research fellows on staff, six fully funded by Physics and Health Sciences (P and HS). The first section of this report contains an excellent topical review of the program in Health Sciences on tritium toxicity which involves scientists from all three of the Chalk River branches of Health Sciences. Their work on cancer proneness is expanding data on apparently normal people and has been extended to include cancer patients. All tests are now blind. The work was the subject of two very fine TV presentations, one each shown on the French and English networks of the CBC. Investigation also continues on the complex influence of hyperthermia on cancer induction and promotion. The potency of natural killer cells in human blood which have the ability to recognize and destroy cancerous cells have been shown to be very sensitive to temperature. A method may have been found for extending the life of T-lymphocytes grown in culture beyond the present 30 to 60-day limit. Activities in environmental research are moving in the direction of studies of a more fundamental nature so that the results will have a certain portability. Model studies form a large part of this new emphasis and notable among those is the Twin Lakes tracer study. Work is in progress to follow the plume the full 240 metres to the discharge zone with considerable success in the mathematical modelling. Members of the Health Sciences unit at CRNL were active as resource people for the Hare Commission on Ontario Nuclear Safety Review during the late fall. At Partnerships for Profit, which brought 85 senior executives of Canadian business in contact with the Research Company's capabilities, Physics and Health Sciences manned four booths on cancer screening, environmental protection, ANDI and nuclear physics instrumentation.

    International Nuclear Information System (INIS)

    Progress of work in Biology and Health Physics Division is reported for first quarter 1978. Measurements of liquid and plastic scintillator responses over a wide range of gamma-ray energies and calculations of the shape of the Compton electron distribution have been made for different scintillator sizes. Other work performed in health physics included determination of errors involved in accurate determination of dose-equivalents resulting from tritium ingestion, and development of radiation monitors and techniques for using them to best advantage. A wide range of environmental studies were underway during the quarter, notably 14 C/ 12 C ratio measurement using an accelerator-spectrometer and contiuing studies of the beneficial uses of thermal effluents. Development of computer linkage techniques for medical records continued. Practical applications of the approach include linkage of personal exposure histories with death records pertaining to the exposed individuals. Work in the Biology Branch has continued to focus upon the effects of radiation on a variety of living organisms, ranging from bacterial viruses to humans. The principal sensitive target for long-term biological effects of radiation on all living organisms is DNA. The chemical nature of the damage caused in DNA by radiation and the response of cells to this damage is being studied by a variety of biochemical and genetic techniques. A review of literature on the causes of cancer in humans has continued. If effects are linearly related to total dose, as is normally assumed for purposes of radiation protection, then the total number of fatal cancers predicted to arise from the use of nuclear power in the future should be about 100 times less than the number induced by urban air pollution resulting from the combustion of coal and oil to produce the same amount of electricity.

    International Nuclear Information System (INIS)

    1976-01-01

    This report summarizes the work carried out at the Nuclear Physics Laboratory of the University of Colorado during the period November 1, 1975 to November 1, 1976. The low energy nuclear physics section is dominated by light-ion reaction studies which span a wide range. These include both two-neutron and two-proton transfer reactions, charge exchange and inelastic scattering, as well as single nucleon transfer reactions. The nuclei studied vary widely in their mass and characteristics. These reaction studies have been aided by the multi-use scattering chamber which now allows the energy-loss-spectrometer beam preparation system (beam swinger) to shift from charged particle studies to neutron time-of-flight studies with a minimum loss of time. The intermediate energy section reflects the increase in activity accompanying the arrival of LAMPF data and the initiation of (p,d) studies at the Indiana separated-sector cyclotron. The nucleon removal results provided by the π beam at EPICS previous to completion of the spectrometer have shown that nuclear effects dominate this process, so that the widely used free interaction picture is inadequate. The section entitled ''Other Activities'' reveals continuing activities in new applications of nuclear techniques to problems in medicine and biology. Reactions important to astrophysics continue to be investigated and our trace-element program remains at a high level of activity. The theoretical section reports new progress in understanding magnitudes of two-step reactions by inclusion of finite-range effects. A new finite-range program which is fast and economical has been completed. Intermediate energy results include calculations of π-γ angular correlations, low energy π-nucleus interactions, as well as (p,d) and nucleon scattering calculations for intermediate energies

    2015-11-01

    This report on progress explores recent advances in our theoretical and experimental understanding of the physics of open quantum systems (OQSs). The study of such systems represents a core problem in modern physics that has evolved to assume an unprecedented interdisciplinary character. OQSs consist of some localized, microscopic, region that is coupled to an external environment by means of an appropriate interaction. Examples of such systems may be found in numerous areas of physics, including atomic and nuclear physics, photonics, biophysics, and mesoscopic physics. It is the latter area that provides the main focus of this review, an emphasis that is driven by the capacity that exists to subject mesoscopic devices to unprecedented control. We thus provide a detailed discussion of the behavior of mesoscopic devices (and other OQSs) in terms of the projection-operator formalism, according to which the system under study is considered to be comprised of a localized region (Q), embedded into a well-defined environment (P) of scattering wavefunctions (with Q   +   P   =   1). The Q subspace must be treated using the concepts of non-Hermitian physics, and of particular interest here is: the capacity of the environment to mediate a coupling between the different states of Q; the role played by the presence of exceptional points (EPs) in the spectra of OQSs; the influence of EPs on the rigidity of the wavefunction phases, and; the ability of EPs to initiate a dynamical phase transition (DPT). EPs are singular points in the continuum, at which two resonance states coalesce, that is where they exhibit a non-avoided crossing. DPTs occur when the quantum dynamics of the open system causes transitions between non-analytically connected states, as a function of some external control parameter. Much like conventional phase transitions, the behavior of the system on one side of the DPT does not serve as a reliable indicator of that on the other. In

    During the past year the principal activities of the CMU Medium Energy Physics Group have included the running of three previously approved experiments, the development of hardware and software for these experiments, and final analysis of previously accumulated data. In a two week run at LEAR at the beginning of this year 100 data tapes were collected on experiment PS-185. This spring sigma hyperon production in Lithium was studied in a run on AGS experiment E-774. We are currently setting up AGS experiment E-788 in an investigation of Lambda weak decay in Helium hypernuclei. In addition a new experiment to search for strangeness S = -2 dibaryon production was presented and approved by the AGS program advisory committee for 1000 h (E-813). For these experiments extensive hardware and software development has taken place, requiring much of the group's effort. Analysis of LEAR experiment PS-185 is in full progress at CMU. Both the weak decay studies of 12 C (AGS E-759) and the pion annihilation studies in Lithium and Oxygen have now been fully analyzed with the results submitted for publication in several papers. All of these activities are described. Specific hardware and software projects are discussed

    Ten years have elapsed since the birth of the National Laboratory for High Energy Physics. For the growth to the present status, the researchers concerned, the Science Council of Japan, the Ministry of Education, the National Diet and many enterprises, all contributed greatly. The proton synchrotron was completed as scheduled, and its performance largely exceeded the initial target. The results of the common utilization experiments started in 1977 have been obtained successively, and the applied research other than the field of elementary particles also has advanced along the right line steadily, such as booster utilization facility and radiated beam experiment facility. In this year, the construction of the Tristan project has been started, and the pet name ''KEK'' is internationally well known now. The 21st century is said to be the age of elementary particles, and the mission and responsibility put on the researchers concerned will be heavier. In this book, the progress of the KEK during ten years is reviewed, and many persons who took part in the establishment of the KEK contributed their memoirs. Also, the round-table talk held on this occasion, the history of each research group, the future plans, the results of researches and the related materials are described. (Kako, I.)

    The past year's research has dealt with a wide range of topics in High-Energy Theoretical Physics. Important new results have been found in the fields of large-N expansions in quantum field theories via an effective Hamiltonian technique, and by the method of classical field equations supplemented by quantum boundary conditions; finite lattice QCD at N/sub c/ = infinity; neutrino oscillations and natural flavor conservation in gauge theory; the vanishing of the renormalized effective potential in phi 4 4 theory; a new method for treating singular differential equations; and an infrared cluster expansion in quantum field theory. In addition, substantial progress has been made in the analyses of lattice gauge theories; studies of factorization properties of mass and infrared singularities in QCD: non-hermitian quantum problems in the context of Gribov field theories; symmetry breaking via contracted groups; the calculation of Cabibbo-type angles and grand unification theories; and strong-coupling methods in gauge and nongauge field theories, using a systematic, lattice-formulated, perturbation theory, and by the extraction of relevant infrared structure

    This report covers the progress on two different tasks, Task A and Task B. Task A focuses on rare and semi-rare decays of {phi} and of the short-lived kaon with emphasis on those aspects needed in preparation for the proposed {Phi}-Factory measurements of CPT violation and {epsilon}{prime}/{epsilon} from the CP-violating decays of the K{sub L}K{sub S} final state. The second aspect of the kaon decay work is participation in the so-called rare kaon decay experiments, E865, at BNL. The major goals of Task B, Fermilab program, are as follows: (1) participation in the analysis of the E706 data taken during the 1990--1991 fixed target run at Fermilab and (2) the continuation of the work with the CDF collaboration particularly the SVX II upgrade. The E706 part of the program involves the completion of publications reporting the results of the 1990--91 data run. The analysis of these data is now mature and physics results are emerging. The CDF program involves a dedicated effort to the design of a silicon vertex detector upgrade, SVX II, to be accomplished by the time Fermilab run II collider run (1999). In addition they are participating in the 1993--1995 collide run Ib and actively analyzing the data from both runs Ia and Ib.

    A search for new physics is performed using isolated same-sign dileptons with at least two b-quark jets in the final state. Results are based on a 4.98 inverse femtobarn sample of proton-proton collisions at a centre-of-mass energy of 7 TeV collected by the CMS detector. No excess above the standard model background is observed. Upper limits at 95% confidence level are set on the number of events from non-standard-model sources. These limits are used to set constraints on a number of new physics models. Information on acceptance and efficiencies are also provided so that the results can be used to confront additional models in an approximate way.
