  1. On-line filtering at the CERN-ISR

    International Nuclear Information System (INIS)

    Frehse, H.

    1981-01-01

    During the last years it has become quite evident that one should aim at trigger systems with high selectivity in order to improve the purity of data and simultaneously remove load from the off-line processing. At the CERN ISR typical pp interaction rates are in the order of 1-3 MHz. Therefore experiments studying low cross section processes need trigger systems which provide reduction factors in the order of 10 5 to avoid dead time losses. The use of programmable devices, allowing for flexible and sophisticated decision schemes, enables experiments to gain a decisive factor in rejection after pre-triggering with more conventional devices. An overview of the different methods employed and their performance is given. (orig.)

    1976-01-01

    The properties of the diffractive peak observed in the mass spectra of systems recoiling against observed high-momentum protons emerging from pp collisions at the CERN ISR have been investigated. The cross sections in this peak have been found to have a steep t dependence which flattens out as mod t mod increases. The high mass side of the peak varies approximately as 1/M/sup 2/ (where M is the missing mass of the recoiling system) and scales well in terms of the variable M /sup 2//s. The position of the maximum has been observed to move to lower values of M/sup 2//s as the kinematic boundary of this variable decreases with increasing s. The measured cross sections, integrated up to M/sup 2//s=0.05, rise by (15+or-5)% over the s range 549 to 1464 GeV/sup 2/. (24 refs).

    1976-01-01

    Data are presented on the semi-inclusive distributions of rapidities of secondary particles produced in pp collisions at very high energies. The experiment was performed at the CERN Intersecting Storage Rings (ISR). The data given, at centre-of-mass energies of square root s=23 and 62 GeV, include the single-particle distributions and two-particle correlations. The semi-inclusive correlations show pronounced short-range correlation effects which have a width considerably narrower than in the case of inclusive correlations. It is shown that these short-range effects can be understood empirically in terms of three parameters whose energy and multiplicity dependence are studied. The data support the picture of multiparticle production in which clusters of small multiplicity and small dispersion are emitted with subsequent decay into hadrons. (32 refs).

    Data on correlations between momentum analysed protons, pions or K mesons, and charged particles produced in pp collisions at the CERN ISR are presented. The charged particles were detected in a approximately 4 pi scintillation counter hodoscope. The pseudo- rapidity distributions are well described by production within the limits of cylindrical phase space, with negative kaons and antiprotons yielding narrower distributions than protons, pions and positive kaons. The azimuthal distributions show symmetry around the t-channel axis in the rest frame of the recoiling mass M/sub X/ in pp to aX(a =detected proton, pion, positive kaon). (14 refs).

    1990-01-01

    A feasibility study has been made for a B-meson factory, using the ISR tunnel and the LEP injector at CERN. An electron-positron collider operated with asymmetric beam energies of 8 and 3.5 GeV at a luminosity of 10 34 cm -2 s -1 will permit decisive answers on the question of CP violation within the framework of the Standard Model. This report outlines the physics motivation and detector requirements and gives a description of the machine design. It is proposed that the design goal is reached in two stages, with a collider with two rings of equal size. In the first stage a luminosity of 10 33 cm -2 s -1 may be achieved, allowing a rich programme of charm, beauty and τ-lepton physics. A further tenfold increase of the luminosity would require additional R and D on various machine aspects. (orig.)

    1981-01-01

    The Split Field Magnet Detector at the CERN ISR has been used in recent years to study events with a high transverse momentum charged particle. As a first level computer based trigger a linear estimate of the track momentum by fixed point arithmethic was calculated on-line by a minicomputer. In addition appreciable further rejection was obtained by off-line filtering on the IBM-370/168, using pattern recognition and a fit of the triggering particle in the magnetic field. The availability of the 168/E emulator makes it possible to transfer the proven methods used off-line to real time data reduction. Preliminary results on filter efficiency and speed for an experiment triggering on a high Psub(T) hadron at 10 to 20 0 with respect to the outgoing beam (Exp. R 419) are given. Possible improvements and extensions are discussed. (orig.)

    The ISR (Intersecting Storage Rings) were two intersecting proton synchrotron rings each with a circumference of 942 m and eight-fold symmetry that were operational for 13 years from 1971 to 1984. The CERN PS injected 26 GeV/c proton beams into the two rings that could accelerate up to 31.4 GeV/c. The ISR worked for physics with beams of 30-40 A over 40-60 hours with luminosities in its superconducting low-β insertion of 1031-1032 cm-2 s-1. The ISR demonstrated the practicality of collider beam physics while catalysing a rapid advance in accelerator technologies and techniques. (author)

    Towards the left one sees, on top of ISR beam 1, the front section of the 30-metre-long, small-angle spectrometer from the CERN-Holland-Lancaster-Manchester single-particle production experiment. It consists of two special septum magnets carrying up to 20 kA each. These magnets are necessary to force charged particles produced at small angles away from the ISR beam. They are followed by two threshold Cerenkov counters and (not visible) three more bending magnets and a 6-metre-long Cerenkov counter. Particle identification follows from the Cerenkov signals after determination of the particle trajectory through the spectrometer with magnetostrictive spark chambers. The positions of the first magnets and Cerenkov counters can be changed by remote control. In front one sees the electronics which determines the traversal of a charged particle from scintillator counter signals and gives the "fire" signal for the spark chambers.

    In this photograph taken in the winter of 1963, CERN still looks quite bare under its mantle of snow. The Proton Synchrotron (PS), resembling a bicycle wheel in shape, had been in operation since the summer of 1959. A proposal had just been made for the site of CERN's second large project, the Intersecting Storage Rings (ISR): France was to house the world's first proton-proton collider. In September 1965, the French authorities signed an agreement making more than 40 hectares of land available for the extension of the CERN site established in Switzerland into French territory. The ISR project received final approval from the CERN Council in December 1965. The civil engineering work on the French part began in November 196

    The previously reported observation of direct electrons produced in proton-proton collisions at the CERN ISR was extended to transverse moments, p*/sub T/, as low as 0.6 GeV/c. The ratio of electron to pion cross sections seems to rise as p*/sub T/ is decreased. It increases by at most a factor of 2 between p*/sub T/ of 2 and 0.6 GeV/c. Results on the s-dependence of this ratio and on correlated charged particles are presented for p*/sub T/ greater than or equal to 1 GeV/c in another work

    Eight superconducting quadrupoles for a high-luminosity insertion in the ISR have been produced by industrial firms according to CERN design and manufacturing specifications, and assembled and tested at CERN. The horizontal cylindrical cryostats, which contain windings and steel yoke in a boiling helium bath, have a 173 mm warm bore. For 31 GeV beam energy, the maximum operating gradient on the quadrupole axis is 43 T m -1 and the maximum field in the windings is 5.5 T. Sextupole windings provide a linear variation of the gradient of up to 4 % over the bore width and dodecapole windings trim the field pattern as a function of excitation. This paper reports about production history, acceptance tests, and performance. The results of magnetic measurements are also summarized. The insertion will be installed into the ISR as from August 1980. (Auth.)

    The inclusive cross section for large psub(T) π 0 production near 90 0 in p-p collisions at the CERN ISR is presented for centre-of-mass energies 30.7, 53.1 and 62.4 GeV. The data are inconsistent with scaling of the form psup(-n)sub(T)F(xsub(T)), with constant n or with n allowed to depend on xsub(T)=2psub(T)/√s. For √s=53.1 and 62.4 GeV, the value of n found for 3.5< psub(T)<7.0 GeV/c is n=8.0+-0.5, in agreement with previous experiments. However, for 7.5< psub(T)<14.0 GeV/c the value becomes n=5.1+-0.4.

His experience in the Laboratory’s international environment was an important factor in the process that led to his becoming one of the first Germans in space.   Ernst Messerschmid in the Spacelab module. Credit: DLR (CC-BY 3.0). Ernst Messerschmid first arrived at CERN as a summer student in 1970, just as preparations were being made for the start-up of the ISR, and he soon returned as a fellow. His diploma thesis and PhD thesis were both based on his work at the ISR.

    The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events: Gentner-Kastler Prize: T he prestigious Gentner-Kastler Prize, jointly awarded by the French and German Physical Societies, goes this year to Walter Schmidt-Parzefall of DESY, formerly leader of the Argus group at the DORIS electron-positron collider at the DESY Laboratory Hamburg, which has made many significant contributions to heavy quark spectroscopy. Subsequently he joined Hamburg University, and has recently played a prominent role in establishing the HERA-B experiment at DESY's HERA electron-proton collider. Before working at DESY, Schmidt-Parzefall spent some time at CERN's Intersecting Storage Rings.; Thirty ISR years: A discreet lunch event at CERN marked the 30th anniversary of the historic decision to go ahead with the Intersecting Storage Rings (ISR) at CERN. Among those present were Victor Weisskopf, CERN's Director General at the time, and Mervyn Hine, responsible for CERN's longterm planning under Weisskopf. The ISR, the world's first proton collider, came into operation in 1971, ahead of schedule, but was shut down in 1984, also ahead of schedule, as part of the bid to divert funds to LEP construction. The ISR, which used the idea of particle stacking to build up the stored beam intensity, was long regarded as a masterpiece of accelerator building, and blazed a trail for CERN's future accelerator projects. Many CERN specialists cut their accelerator teeth at the ISR.; ICTP Dirac Medal: The International Centre for Theoretical Physics (ICTP), Trieste, is awarding its 1995 Dirac Medal to Michael Berry of Bristol for his discovery of the non-integrable phase that arises in adiabatic processes in quantum theory.

  8. Viewpoint. The decision to build the ISR and its consequences: the role of Victor Weisskopf

    1995-01-01

    December 1995 marks the thirtieth anniversary of the decision by the CERN Council to approve the proposal by the then Director General Victor Weisskopf to build the Intersecting Storage Rings (ISR). It was probably the Council's most important decision since setting up the Laboratory, judging by its consequences for physics and for CERN over the following three decades. December is also the twenty-fifth anniversary of the startup of the machine which led to a period of developments in accelerator technology with far reaching consequences. They included the production of stable high current stacked beams with high interaction rates in the presence of non-linear resonances and space charge, the inventions of stochastic cooling and of beam instrumentation using Schottky scans, and the technology of large ultra-high vacuum chambers with controlled wall impedance and resonances, to name only a few. Two results from the ISR physics programme of similar importance for the future were the first observation of large particle and photon yields with high transverse momentum (indicative of quark-gluon processes deep inside the colliding protons), and the consequent development of concepts for detectors with full solid angle calorimetry and tracking coverage, now used on all colliders. The technical success of the machine and the significance of the physics results led to a radical switch in physicists' thinking everywhere, away from fixed targets and towards colliders as the way to higher collision energies for hadrons. The ISR ceased to be seen as a toy for accelerator builders and became a window into a future far beyond the possibilities of fixed target accelerators. The ISR advances in accelerator and detector technology stimulated the conversion of the SPS to a proton-antiproton collider and the similar conversion of the Fermilab machine, and led to the proposals for the Superconducting Supercollider (SSC) in the USA and the LHC in Europe, to plans for a

    Emerging cloud computing platforms offer an ideal opportunity for Intelligence, Surveillance, and Reconnaissance (ISR) intelligence analysis. Cloud computing platforms help overcome challenges and limitations of traditional ISR architectures. Modern ISR architectures can benefit from examining commercial cloud applications, especially as they relate to user experience, usage profiling, and transformational business models. This paper outlines legacy ISR architectures and their limitations, presents an overview of cloud technologies and their applications to the ISR intelligence mission, and presents an idealized ISR architecture implemented with cloud computing.

    This is a detailed guide to the use of the current version of a FORTRAN program for carrying out computations required in the design or modification of alternating-gradient synchrotrons and storage rings. The program, which runs on the CDC 7600 computer at CERN, computes linear transformation functions, and modifications of parameters to achieve specified properties; it tracks sets of particle trajectories, finds closed orbits when elements of the structure are displaced, computes the equilibrium orbit, designs closed-orbit bumps, tracks betatron functions through the structure, and matches insertions in the structure to specified betatron and dispersion functions. The report supersedes CERN 69-5 (AGS - The ISR computer system for synchrotron design and orbit analysis, by E. Keil and P. Strolin). (Author)

    A fast and flexible trigger processor system designed to run in parallel up to 51 different types of trigger is used in a large hadron calorimeter experiment at CERN-ISR. A very fast data bus connected to 255 10 bit address ECL memory chips allows programmable selection of events according to their topology and energy pattern in less than 150 ns. In addition this system can interrogate two programmable processors (ESOP) to isolate events characterized by a large energy flow in the central drift chamber (< 500 μs). All functions of the trigger processor can be checked externally by a computer through injecting in parallel simulated input signals into various stages of the system. Salient features and performances will be discussed

    A special open ISRC meeting was held on 20 September 1982 to present a 'comparative review and future perspectives of ISR physics'. In this report we summarize some of the contributions, with special emphasis on some areas of physics where the ISR are unique and irreplaceable, and which are of fundamental importance. We concentrate on physics with high-psub(T) jets, identified hadrons and single photons, and on heavy-flavour production. We believe that ISR experiments can make decisive experimental tests of quantum chromodynamics or any alternative theories of the strong interaction. (orig.)

    This is a specialized course which addresses a wide spectrum of theoretical and technological problems confronting the designer of an antiproton facility for high-energy-physics research. A broad and profound basis is provided by the lecturers' substantial experience gained over many years with CERN's unique equipment. Topics include beam optics, special lattices for antiproton accumulation and storage rings, antiproton production, stochastic cooling, acceleration and storage, r.f. noise, r.f. beam manipulations, beam-beam interaction, beam stability due to ion accumulation, and diagnostics. The SPS (Super Proton Synchrotron) panti p collider, LEAR (the Low Energy Antiproton Ring at CERN), antiprotons in the ISR (Intersecting Storage Rings), the new antiproton collector (ACOL) and gas jet targets are also discussed. A table is included listing the parameters of all CERN's accelerators and storage rings. See hints under the relevant topics. (orig./HSI)

  18. ISR RF cavities

    CERN Multimedia

    1983-01-01

    In each ISR ring the radiofrequency cavities were installed in one 9 m long straight section. The RF system of the ISR had the main purpose to stack buckets of particles (most of the time protons)coming from the CPS and also to accelerate the stacked beam. The installed RF power per ring was 18 kW giving a peak accelerating voltage of 20 kV. The system had a very fine regulation feature allowing to lower the voltage down to 75 V in a smooth and well controlled fashion.

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

    Current multinational operations show an increased demand for high quality actionable intelligence for different operational levels and users. In order to achieve sufficient availability, quality and reliability of information, various ISR assets are orchestrated within operational theatres. Especially airborne Intelligence, Surveillance and Reconnaissance (ISR) assets provide - due to their endurance, non-intrusiveness, robustness, wide spectrum of sensors and flexibility to mission changes - significant intelligence coverage of areas of interest. An efficient and balanced utilization of airborne ISR assets calls for advanced concepts for the entire ISR process framework including the Tasking, Collection, Processing, Exploitation and Dissemination (TCPED). Beyond this, the employment of current visualization concepts, shared information bases and information customer profiles, as well as an adequate combination of ISR sensors with different information age and dynamic (online) retasking process elements provides the optimization of interlinked TCPED processes towards higher process robustness, shorter process duration, more flexibility between ISR missions and, finally, adequate "entry points" for information requirements by operational users and commands. In addition, relevant Trade-offs of distributed and dynamic TCPED processes are examined and future trends are depicted.

    2002-01-01

    This experiment is a measurement of small angle scattering of antiprotons on protons and of protons on protons at 15/15, 22/22, 26/26 and 31/31 GeV, with the aim of obtaining data on the total cross-section for the scattering of protons on protons, and of determining the ratio of the real to the imaginary scattering amplitude at zero momentum transfer for antiprotons on protons. The measurement is divided into two parts: \\item 1) The measurement of @s^t^o^t(@*p) and @s^t^o^t(pp), using hodoscopes placed at small angles, outside the vacuum pipe, at approximately 9 metres from the intersection point. \\item 2) The measurement of the region in !t!, the momentum transfer squared, around the value !t^c!, where Coulomb and nuclear scattering are equal, in order to deduce the quantity @r = Re f(t=0)/Im f(t=0). This latter measurement is done by employi in earlier @s^t(pp) and @r experiments at the ISR. \\end{enumerate} In both set-ups the measurements are made by recording coincidences between collinear counters in th...

    After six months of work, the part of the ISR coming under EP Division has been emptied and refurbished. The area is now ready to start building the LHC experiments. People who know the ISR from way back are likely to be surprised when they push open the doors to the old collider. Whereas the part of the tunnel allocated to EP (Experimental Physics) Division now stands empty, a few months ago, it was piled high with odds and ends. For more than 20 years, this part of the former Intersecting Storage Rings, a full quarter of the loop, had been used as storage space.

    Neutron spectra in pp collisions at ISR energies are studied in the framework of sum rules for inclusive processes. The contributions of protons, π- and E- mesons to the energy sum rule are calculated at √5 = 53 GeV. It is shown by means of this sum rule that the spectra of neutrons at the ISR are in contradiction with the spectra of other particles also measured at the ISR

    The coming into operation of the Intersecting Storage Rings (ISR) at the European Centre of Nuclear Research (CERN), near Geneva, has made it possible in the past two years to study the behaviour of matter at the highest densities ever obtained artificially, hundreds of times greater than the density of matter in nuclei and even in the densest stars. An account is given of some of the results obtained thus far; this is followed by a brief discussion of possible future developments. (17 refs).

    The inclusive production of electron pairs with and without additional photons was measured at the CERN Intersecting Storage Rings (ISR). The investigation of J/psi particles with associated photons indicated that 47 +- 8% of the J/psi were produced via the photonic decay of one of the chi(3.5) states. The upper limit of the production cross-section ratio times the branching ratio into electron pairs of psi' relative to J/psi was found to be 2% at centre-of-mass energy of √s = 62 GeV. (Auth.)

    There were 48 of these Quadrupoles in the ISR. They were distributed around the rings according to the so-called Terwilliger scheme. Their aperture was 184 mm, their core length 300 mm, their gradient 5 T/m. Due to their small length as compared to the aperture, the end fringe field errors had to be compensated by suitably shaping the poles.

    2012-06-01

    There has been significant progress recognizing the value of Intelligence, Surveillance, and Reconnaissance (ISR) activities supporting Situational Awareness and Command and Control functions during the past several decades. We consider ISR operations to be proactive (discovering activities or areas of interest), active (activities performed for a particular task that flows down from a hierarchical process) or reactive (critical information gathering due to unexpected events). ISR synchronization includes the analysis and prioritization of information requirements, identification of intelligence gaps and the recommendation of available resources to gather information of interest, for all types of ISR operations. It has become critically important to perform synchronized ISR activities to maximize the efficient utilization of limited resources (both in quantity and capabilities) and, simultaneously, to increase the accuracy and timeliness of the information gain. A study evaluating the existing technologies and processes supporting ISR activities is performed suggesting a rigorous system optimization approach to the ISR synchronization process. Unfortunately, this approach is not used today. The study identifies existing gaps between the current ISR synchronization process and the proposed system optimization approach in the areas of communication and collaboration tools and advanced decision aids (analytics). Solutions are recommended that will help close this gap.

    Study Objective: To investigate the effectiveness of intensive sleep retraining in comparison and combination with traditional behavioral intervention for chronic primary insomnia. Participants: Seventy-nine volunteers with chronic sleep-onset insomnia (with or without sleep maintenance difficulties) were randomly assigned either to intensive sleep retraining (ISR), stimulus control therapy (SCT), ISR plus SCT, or the control (sleep hygiene) treatment condition. Intervention: ISR treatment consisted of 50 sleep onset trials over a 25-h sleep deprivation period. Measurements and Results: Treatment response was assessed with sleep diary, activity monitoring, and questionnaire measures. The active treatment groups (ISR, SCT, ISR+SCT) all resulted in significant improvements in sleep onset latency and sleep efficiency, with moderate to large effect sizes from pre- to post-treatment. Wake time after sleep onset decreased significantly in the SCT and ISR+SCT groups. Total sleep time increased significantly in the ISR and ISR+SCT treatment groups. Participants receiving ISR (ISR, ISR+SCT) experienced rapidly improved SOL and TST during treatment, suggesting an advantage of rapid improvements in sleep in response to ISR. Although there were few statistically significant differences between groups on individual variables, ISR+SCT resulted in consistently larger effect sizes of change than other treatments, including questionnaire measures of sleep quality, sleep self-efficacy, and daytime functioning. The combination treatment group (ISR+SCT) showed trends to outperform other active treatment groups with fewer treatment dropouts, and a greater proportion of treatment responders with 61% reaching “good sleeper” status. Treatment gains achieved at post-treatment in the active treatment groups were largely maintained throughout follow-up periods to 6 months. Conclusion: This 25-hour intensive conditioning treatment for chronic insomnia can produce rapid improvements in

  18. The science of autonomy: integrating autonomous systems with the ISR enterprise

    2013-05-01

    Consider a future where joint, unmanned operations are the norm. A fleet of autonomous airborne systems conducts overwatch and surveillance for their land and sea brethren, accurately reporting adversary position and aptly guiding the group of autonomous land and sea warriors into position to conduct a successful takedown. Sounds a bit like science fiction, but reality is just around the corner. The DoD ISR Enterprise has evolved significantly over the past decade and has learned many a harsh lesson along the way. Autonomous system operations supporting the warfighter have also evolved, arguably to a point where integration into the ISR Enterprise is a must, in order to reap the benefits that these highly capable systems possess. Achieving meaningful integration, however, is not without its challenges. The ISR Enterprise, for example, is still plagued with "stovepipe" efforts - sufficiently filling a niche for an immediate customer need, but doing little to service the needs of the greater enterprise. This paper will examine the science of autonomy, the challenges and potential benefits that it brings to the ISR Enterprise and recommendations that will facilitate smooth integration of emerging autonomous systems with the mature suite of traditional manned and unmanned ISR platforms.

  19. Access control within military C4ISR systems

    Science.gov (United States)

    Maschino, Mike

    2003-07-01

    Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) tactical battlefield systems must provide the right information and resources to the right individuals at the right time. At the same time, the C4ISR system must enforce access controls to prevent the wrong individuals from obtaining sensitive information, or consuming scarce resources. Because lives, missions and property depend upon them, these access control mechanisms must be effective, reliable, efficient and flexible. The mechanisms employed must suit the nature of the items that are to be protected, as well as the varieties of access policies that must be enforced, and the types of access that will be made to these items. Some access control technologies are inherently centralized, while others are suitable for distributed implementation. The C4ISR architect must select from among the available technologies a combination of mechanisms that eases the burden of policy administration, but is inherently survivable, accurate, resource efficient, and which provides low latency. This paper explores various alternative access enforcement mechanisms, and assesses their effectiveness in managing policy-driven access control within the battlespace.

  20. An agile acquisition decision-support workbench for evaluating ISR effectiveness

    2011-06-01

    The U.S. Air Force is consistently evolving to support current and future operations through the planning and execution of intelligence, surveillance and reconnaissance (ISR) missions. However, it is a challenge to maintain a precise awareness of current and emerging ISR capabilities to properly prepare for future conflicts. We present a decisionsupport tool for acquisition managers to empirically compare ISR capabilities and approaches to employing them, thereby enabling the DoD to acquire ISR platforms and sensors that provide the greatest return on investment. We have developed an analysis environment to perform modeling and simulation-based experiments to objectively compare alternatives. First, the analyst specifies an operational scenario for an area of operations by providing terrain and threat information; a set of nominated collections; sensor and platform capabilities; and processing, exploitation, and dissemination (PED) capacities. Next, the analyst selects and configures ISR collection strategies to generate collection plans. The analyst then defines customizable measures of effectiveness or performance to compute during the experiment. Finally, the analyst empirically compares the efficacy of each solution and generates concise reports to document their conclusions, providing traceable evidence for acquisition decisions. Our capability demonstrates the utility of using a workbench environment for analysts to design and run experiments. Crafting impartial metrics enables the acquisition manager to focus on evaluating solutions based on specific military needs. Finally, the metric and collection plan visualizations provide an intuitive understanding of the suitability of particular solutions. This facilitates a more agile acquisition strategy that handles rapidly changing technology in response to current military needs.

    At the inauguration ceremony for the Intersecting Storage Rings (ISR) on 16 October 1971, the man in charge of their construction, Kjell Johnsen, presented the "key" to the machine to Edoardo Amaldi, President of Council. Seated on the stage with them for this symbolic event were Victor Weisskopf, Marcel Antonioz, Willy Jentschke (seen on the left of the photo) and Werner Heisenberg (on the far right). On 27 January that year, in a world premier, signals produced by proton-proton collisions had been observed at the ISR. The protons, supplied by the PS, were injected into two identical rings, each measuring 300 metres in diameter, and collided head on at the 8 points where the rings intersected. The installation, which remained in operation until 1984, gave physicists access to a wide range of energies for hadron physics, hitherto restricted to the data from cosmic ray studies. The many technological challenges that were met at the ISR, in the fields of vacuum technology and stochastic cooling for instance,...

    This report is a complete account of the transformations and corrections necessary for geodetic quantities, whether directly measured or derived, before they can be entered into calculations involving the basic reference system used at CERN. A special type of projection (orthographic projection) has been developed, with the aim that it be the best possible for the geodetic system employed for the Super Proton Synchrotron (SPS) whilst retaining the basic possibilities provided for the Proton Synchrotron (PS) and the Intersecting Storage Rings (ISR). The coordinate system in which the geometry of particle beams is defined is necessarily Cartesian. This feature, although mathematically simple, has a number of consequences for the treatment of measurements which are physically connected with the shape of the Earth. Details of the orthographic projection, the planimetry, and the altimetry are given. (Author) [fr

    There is considerable interest in natural language conversational interfaces. These allow for complex user interactions with systems, such as fulfilling information requirements in dynamic environments, without requiring extensive training or a technical background (e.g. in formal query languages or schemas). To leverage the advantages of conversational interactions we propose CE-SAM (Controlled English Sensor Assignment to Missions), a system that guides users through refining and satisfying their information needs in the context of Intelligence, Surveillance, and Reconnaissance (ISR) operations. The rapidly-increasing availability of sensing assets and other information sources poses substantial challenges to effective ISR resource management. In a coalition context, the problem is even more complex, because assets may be "owned" by different partners. We show how CE-SAM allows a user to refine and relate their ISR information needs to pre-existing concepts in an ISR knowledge base, via conversational interaction implemented on a tablet device. The knowledge base is represented using Controlled English (CE) - a form of controlled natural language that is both human-readable and machine processable (i.e. can be used to implement automated reasoning). Users interact with the CE-SAM conversational interface using natural language, which the system converts to CE for feeding-back to the user for confirmation (e.g. to reduce misunderstanding). We show that this process not only allows users to access the assets that can support their mission needs, but also assists them in extending the CE knowledge base with new concepts.

    In an analysis of ``minimum bias'' data taken in experiment R415 it was shown that if this data is analysed in terms of a new energy variable E^h^a^d, obtained by correcting the ISR c.m. energy for the energy carried away by the leading protons, then there is a remarkable similarity between (pp) and (e|+e|-) interactions. The range of (e|+e|-) equivalent energies over which the data could be analysed was limited by the total c.m. energy of the colliding protons (@Rs=62~GeV). \\\\ \\\\ This experiment at the Split Field Magnet uses a momentum-selective trigger logic to collect an enriched sample of events with identified leading protons or antiprotons, covering an extended range of equivalent (e|+e|-) energies by collecting data at different~@Rs.\\\\ \\\\ A first run with proton-proton at three different @Rs (30, 44 and 62~GeV) was already performed. \\\\ \\\\ The hypothesis that the energy released by the leading protons, and not @Rs, is the important quantity when studying low p^t multiparticle production in (pp) collis...

    This report is a detailed account of the transformations and corrections that must be applied to any geodetic quantity - whether directly observed or derived - before it can be introduced into calculations relating to the reference system of coordinates used at CERN. In particular, a type of projection, called orthographic projection, has been developed to be as well adapted as possible to the geodetic network of the Subterranean Proton Synchrotron (SPS), while preserving the basic possibilities of the other installations - i.e., the Proton Synchrotron (PS) and the Intersecting Storage Rings (ISR). The system in which the particle beam geometry is defined is necessarily cartesian. This feature, though mathematically simple, nevertheless has numerous consequences for the treatment of measurements that are physically connected to the shape of the earth. The calculations of the orthographic projection, the planimetry and the altimetry are presented in detail. 12 figures

    The Large Hadron Collider is exploring the new frontier of particle physics. It is the largest and most ambitious scientific instrument ever built and 100 years after the Rutherford experiment it continues that tradition of “smashing atoms” to unveil the secret of the infinitely small. LHC makes use of all what we learnt in 40 years of hadron colliders, in particular of ISR and Sp-pbarS at CERN and Tevatron at Fermilab, and it is based on Superconductivity, discovered also 100 years ago. Designing, developing the technology, building and finally commissioning the LHC took more than twenty years. While LHC is now successfully running, we are already preparing the future for the next step. First, by increasing of a factor five the LHC luminosity in ten years from now, and then by increasing its energy by a factor two or more, on the horizon of the next twenty years. These LHC upgrades, in luminosity and energy, will be the super-exploitation of the CERN infrastructure and is the best investment that the HEP...

    The 32 correction 6-pole magnets had the special feature of having an asymmetric aperture of 192 mm (horizontal) x 112 mm (vertical), the two central poles having been brought closer to the ISR elliptical vacuum chamber in order to save Ampere-turns and power. In fact for a given strength the required Ampere-turns per pole are proportional to the cube of its distance from the centre. The low-carbon steel core was 396 mm long , the strength 28 T/m. The strong dipole field generated at the ends by the asymmetry, as well as other unwanted multipoles, were compensated by suitable shaping of the pole profiles.

  11. Smart systems, dumb data: impact on ISR operations

    2013-05-01

    Just as we face a global environment where the latest technology is most needed by Department of Defense (DoD) and the Intelligence Community (IC), we find ourselves hindered by the lack of smart, useful data that our intelligent systems and workforce can fully exploit. Consider the ISR Enterprise "system of systems." Our inability to properly populate metadata fields for making data discoverable and useful is as harmful to system performance as putting lowgrade fuel in a race car. In order for our downstream ISR Enterprise systems (and analysts) to achieve their full performance potential, we must take measures upstream to make the data stream smart. This paper will examine the challenges and ongoing efforts that will benefit analysts at all echelons.

  12. Beam position pickup for antiprotons to the ISR

    1981-01-01

    The Antiproton Project, launched for proton-antiproton collisions in the SPS (SPS collider), had a side-line for p-pbar collisions in the ISR. A new transfer line, TT6, was constructed to transport antiprotons from the 26 GeV PS to the injection line TT1 of ISR ring 2. Antiprotons were a scarce commodity. For setting up the lines, beam diagnostic devices in the antiproton path had to work reliably and precisely with just a few low-intensity pilot pules: single bunches of about 2x10**9 antiprotons every few hours. Electrostatic pickup electrodes were used to measure beam position. They could be mounted for measurement in the horizontal plane, as in this picture, or at 90 deg, for the vertical plane.

    2012-05-01

    Full Text Available In this study, the molecular basis of the induced systemic resistance (ISR in Arabidopsis thaliana by the biocontrol fungus Trichoderma hamatum T382 against the phytopathogen Botrytis cinerea B05-10 was unraveled by microarray analysis both before (ISR-prime and after (ISR-boost additional pathogen inoculation. The observed high numbers of differentially expressed genes allowed us to classify them according to the biological pathways in which they are involved. By focusing on pathways instead of genes, a holistic picture of the mechanisms underlying ISR emerged. In general, a close resemblance is observed between ISR-prime and systemic acquired resistance (SAR, the systemic defense response that is triggered in plants upon pathogen infection leading to increased resistance towards secondary infections. Treatment with Trichoderma hamatum T382 primes the plant (ISR-prime, resulting in an accelerated activation of the defense response against Botrytis cinerea during ISR-boost and a subsequent moderation of the Botrytis cinerea induced defense response (BIDR. Microarray results were confirmed for representative genes by qRT-PCR, by analysis of transgenic plants expressing relevant promoter-GUS constructs and by phenotypic analysis of mutants affected in various defense-related pathways, thereby proving the validity of our approach.

    In the wake of rapid maturing of Internet of Things (IoT) approaches and technologies in the commercial sector, the IoT is increasingly seen as a key `disruptive' technology in military environments. Future operational environments are expected to be characterized by a lower proportion of human participants and a higher proportion of autonomous and semi-autonomous devices. This view is reflected in both US `third offset' and UK `information age' thinking and is likely to have a profound effect on how multinational coalition operations are conducted in the future. Much of the initial consideration of IoT adoption in the military domain has rightly focused on security concerns, reflecting similar cautions in the early era of electronic commerce. As IoT approaches mature, this initial technical focus is likely to shift to considerations of interactivity and policy. In this paper, rather than considering the broader range of IoT applications in the military context, we focus on roles for IoT concepts and devices in future intelligence, surveillance and reconnaissance (ISR) tasks, drawing on experience in sensor-mission resourcing and human-computer collaboration (HCC) for ISR. We highlight the importance of low training overheads in the adoption of IoT approaches, and the need to balance proactivity and interactivity (push vs pull modes). As with sensing systems over the last decade, we emphasize that, to be valuable in ISR tasks, IoT devices will need a degree of mission-awareness in addition to an ability to self-manage their limited resources (power, memory, bandwidth, computation, etc). In coalition operations, the management and potential sharing of IoT devices and systems among partners (e.g., in cross-coalition tactical-edge ISR teams) becomes a key issue due heterogeneous factors such as language, policy, procedure and doctrine. Finally, we briefly outline a platform that we have developed in order to experiment with human-IoT teaming on ISR tasks, in both

  18. Experimental study and numerical modelling of geochemical reactions occurring during uranium in situ recovery (ISR) mining

    International Nuclear Information System (INIS)

    Ben Simon, R.

    2011-09-01

    The in situ Recovery (ISR) method consists of ore mining by in situ chemical leaching with acid or alkaline solutions. ISR takes place underground and is therefore limited to the analysis of the pumped solutions, hence ISR mine management is still empirical. Numerical modelling has been considered to achieve more efficient management of this process. Three different phenomena have to be taken into account for numerical simulations of uranium ISR mining: (1) geochemical reactions; (2) the kinetics of these reactions, and (3) hydrodynamic transport with respect to the reaction kinetics. Leaching tests have been conducted on ore samples from an uranium mine in Tortkuduk (Kazakhstan) where ISR is conducted by acid leaching. Two types of leaching experiments were performed: (1) tests in batch reactors; and (2) extraction in flow through columns. The assumptions deduced from the leaching tests were tested and validated by modelling the laboratory experiments with the numerical codes CHESS and HYTEC, both developed at the Geosciences research center of Mines ParisTech. A well-constrained 1D hydrogeochemical transport model of the ISR process at laboratory-scale was proposed. It enables to translate the chemical release sequence that is observed during experiments into a geochemical reaction sequence. It was possible to highlight the controlling factors of uranium dissolution, and the precipitation of secondary mineral phase in the deposit, as well as the determination of the relative importance of these factors.

Two kinds of PIG ion sources with permanent magnets and LEBT were installed and optimized for the injection into these two RFQs. The positive O + and negative O - ions were extracted and accelerated separately as well as simultaneously. The output macro pulse O - beam current reached 660 μA at a transmission efficiency of more than 82%. The N + beam was also accelerated with similar transmission efficiency, but the output current intensity for positive ions were lower than the negative ions because of the extracted current limitation of ion sources. The improvements, especially for high duty factor and experimental results with the 1 MeV ISR RFQ will be presented in this paper

    Full Text Available Biocontrol of plant diseases through induction of systemic resistance is an environmental friendly substitute to chemicals in crop protection measures. Different biotic and abiotic elicitors can trigger the plant for induced resistance. Present study was designed to explore the potential of Pseudomonas aeruginosa PM12 in inducing systemic resistance in tomato against Fusarium wilt. Initially the bioactive compound, responsible for ISR, was separated and identified from extracellular filtrate of P. aeruginosa PM12. After that purification and characterization of the bacterial crude extracts was carried out through a series of organic solvents. The fractions exhibiting ISR activity were further divided into sub-fractions through column chromatography. Sub fraction showing maximum ISR activity was subjected to Gas chromatography/mass spectrometry for the identification of compounds. Analytical result showed three compounds in the ISR active sub-fraction viz: 3-hydroxy-5-methoxy benzene methanol (HMB, eugenol and tyrosine. Subsequent bioassays proved that HMB is the potential ISR determinant that significantly ameliorated Fusarium wilt of tomato when applied as soil drench method at the rate of 10 mM. In the next step of this study, GC-MS analysis was performed to detect changes induced in primary and secondary metabolites of tomato plants by the ISR determinant. Plants were treated with HMB and Fusarium oxysporum in different combinations showing intensive re- modulations in defense related pathways. This work concludes that HMB is the potential elicitor involved in dynamic reprogramming of plant pathways which functionally contributes in defense responses. Furthermore the use of biocontrol agents as natural enemies of soil borne pathogens besides enhancing production potential of crop can provide a complementary tactic for sustainable integrated pest management.

    At the ISR intersection points the vacuum chambers had to be as "transparent" as possible, for the p-p collision product particles to reach the detectors with minimum hindrance. This meant the choice of a light, yet very strong, metal; minimum thickness; and corrugation for mechanical strength. The test-chamber seen here was made of 0.6 mm thick corrugated titanium, obviously not strong enough to withstand the atmospheric pressure.

  6. ISR Radial Field Magnet

    CERN Multimedia

    1983-01-01

    There were 37 (normal) + 3 (special) Radial Field magnets in the ISR to adjust vertically the closed orbit. Gap heights and strengths were 200 mm and .12 Tm in the normal magnets, 220 mm and .18 Tm in the special ones. The core length was 430 mm in both types. Due to their small length as compared to the gap heights the end fringe field errors were very important and had to be compensated by suitably shaping the poles. In order to save on cables, as these magnets were located very far from their power supplies, the coils of the normal type magnets were formed by many turns of solid cpper conductor with some interleaved layers of hollow conductor directly cooled by circulating water

An estimate of the total LAMBDA 0 and anti LAMBDA 0 inclusive cross sections is presented. The measured data are extrapolated to x = 0 using √s = 44 GeV CERN Intersecting Storage Ring results. The cross sections for LAMBDA 0 and anti LAMBDA 0 are found to be 4.42 +- 0.18 mb and 1.17 +- 0.40 mb at 1500 GeV/c and 4.72 +- 0.18 mb. and 1.37 +- 0.48 mb at 2100 GeV/c respectively. The total exactly equal to - inclusive cross section in the region x > 0.4 is found to be. In addition, results are presented of searches for reactions: pp →(LAMBDA 0 anti LAMBDA 0 ) +x and pp→(LAMBDA 0 LAMBDA 0 )+x. Pair production of LAMBDA 0 anti LAMBDA 0 with x > 0.6 is measured to be 1.7 +-/0.2μb, while LAMBDA 0 LAMBDA 0 cross section in the same x range is less than 1.0 +- 0.1 μb

    Shirey, Russell G.; Borntrager, Luke A.; Soine, Andrew T.; Green, David M.

    2017-04-01

    The Air Force Research Laboratory (AFRL) - Sensors Directorate has developed the Blue Guardian program to demonstrate advanced sensing technology utilizing open architectures in operationally relevant environments. Blue Guardian has adopted the core concepts and principles of the Air Force Rapid Capabilities Office (AFRCO) Open Mission Systems (OMS) initiative to implement an open Intelligence, Surveillance and Reconnaissance (ISR) platform architecture. Using this new OMS standard provides a business case to reduce cost and program schedules for industry and the Department of Defense (DoD). Blue Guardian is an early adopting program of OMS and provides much needed science and technology improvements, development, testing, and implementation of OMS for ISR purposes. This paper presents results and lessons learned under the Blue Guardian Project Shepherd program which conducted Multi-INT operational demonstrations in the Joint Interagency Task Force - South (JIATF-S) and USSOUTHCOM area of operations in early 2016. Further, on-going research is discussed to enhance Blue Guardian Multi-INT ISR capabilities to support additional mission sets and platforms, including unmanned operations over line of sight (LOS) and beyond line of sight (BLOS) datalinks. An implementation of additional OMS message sets and services to support off-platform sensor command and control using OMS/UCI data structures and dissemination of sensor product data/metadata is explored. Lastly, the Blue Guardian team is working with the AgilePod program to use OMS in a full Government Data Rights Pod to rapidly swap these sensors to different aircraft. The union of the AgilePod (which uses SOSA compliant standards) and OMS technologies under Blue Guardian programs is discussed.

    "Roman pots" are stainless steel containers, which can be moved from outside the vacuum chamber towards the beam. They house detectors which are conveniently at atmospheric pressure and can still be brought close to the limit of the circulating beam, to detect particles emanating at very small angles from the intersection of two colliding beams. Eifionydd Jones was the inventor of this device, highly successful at the ISR and now used again at the TOTEM experiment at the LHC. This particular Roman Pot, with a thickness of 0.2 mm, was built in 1980 for experiment R210 in intersection I-2, in preparation for proton-antiproton collisions in 1981. See also 7501065.

The Proton Synchrotron (PS), resembling a bicycle wheel in shape, had been in operation since the summer of 1959. A proposal had just been made for the site of CERN's second large project, the Intersecting Storage Rings (ISR): France was to house the world's first proton-proton collider. In September 1965, the French authorities signed an agreement making more than 40 hectares of land available for the extension of the CERN site established in Switzerland into French territory. The ISR project received final approval from the CERN Council in December 1965. The civil engineering work on the French part began in November 1966.

    This is one of the bicone chambers made of titanium for experiment R 702. The central corrugated part had a very thin titanium wall (0.28 mm). The first of these chambers collapsed in its central part when baked at 300 C (August 1975). After an intensive effort to develop better quality and reproducible welds for this special material, the ISR workshop was able to build two new chambers of this type. One of them was installed at I 7 for R 702 in 1976 and worked perfectly. It was at that time the most "transparent" intersection vacuum chamber. See also 7609219, 7609221.

    Rahm, D.C.

    1980-01-01

    The direct photon production in pp collisions for c.m. energies 31 less than or equal to 63 GeV and transverse momenta of up to 9 GeV/c were measured at the ISR by use of a segmented lead/liquid argon calorimeter. The observed γ/π 0 ratio was found to be a significantly larger than zero at 4 GeV/c in p/sub T/, increasing to 0.4 at 9 GeV/c. The average multiplicity on the trigger side for the single-photon events was found to be significantly lower than for π 0 events. The correlations in Δy and Δphi between the trigger particle and an additional particle were found to differe mainly at small Δy and Δphi. 3 figures

  10. Lepton pair production at ISR energies and QCD

    International Nuclear Information System (INIS)

    Altarelli, G.; Martinelli, G.

    1985-01-01

    Motivated by some recent results from the ISR we have considered all available data on the production of Drell-Yan pairs by high energy proton beams. We show that the lepton pair cross sections and qsub(T) distributions are correctly described by QCD using the known distributions of partons in the proton and acceptable values of the QCD scale Λ. No other free parameter is required. Within the accuracy of the data no appreciable intrinsic transverse momentum is needed. (orig.)

  13. Comments on airborne ISR radar utilization

    Science.gov (United States)

    Doerry, A. W.

    2016-05-01

    A sensor/payload operator for modern multi-sensor multi-mode Intelligence, Surveillance, and Reconnaissance (ISR) platforms is often confronted with a plethora of options in sensors and sensor modes. This often leads an over-worked operator to down-select to favorite sensors and modes; for example a justifiably favorite Full Motion Video (FMV) sensor at the expense of radar modes, even if radar modes can offer unique and advantageous information. At best, sensors might be used in a serial monogamous fashion with some cross-cueing. The challenge is then to increase the utilization of the radar modes in a manner attractive to the sensor/payload operator. We propose that this is best accomplished by combining sensor modes and displays into `super-modes'.

  17. Mounting an ISR intersection chamber in the Split Field Magnet(SFM)

    CERN Multimedia

    1977-01-01

    The Split Field Magnet (SFM) was the largest spectrometer for particles from beam-beam collisions in the ISR. It could determine particle momenta in a large solid angle, but was designed mainly for the analysis of forward travelling particles.As the magnet was working on the ISR circulating beams, its magnetic field had to be such as to restore the correct proton orbit.The SFM, therefore, produced zero field at the crossing point and fields of opposite signs upstream and downstream of it and was completed by 2 large and 2 small compensator magnets. The gradient effects were corrected by magnetic channels equipped with movable flaps. The useful magnetic field volume was 28 m3, the induction in the median plane 1.14 T, the gap heigth 1.1 m, the length 10.5 m, the weight about 1000 ton.Concerning the detectors, the SFM was the first massive application of multiwire proportional chambers (about 70000 wires) which filled the main and the large compensator magnets. In the course of the years different types of vacu...

  3. Beam stability in the ISR

    International Nuclear Information System (INIS)

    Hofmann, A.

    1979-01-01

    There are 3 effects which limit the current in the ISR: the gas desorption by the beam produced ions leads to a pressure rise at a certain beam current. To increase this current limit the vacuum system has been improved continuously which resulted in a maximum beam current of 50 A. The microwave instability leads to a dilution of the longitudinal phase space density during acceleration of the bunches across the chamber and during debunching. This limits the longitudinal density of the final stack and therefore the total current which can be accumulated in the given aperture. The transverse instability of the coasting beam represents another potential limitation of the beam current. This effect is controlled by Landau damping provided by the betatron frequency spread and by feedback systems. The ion induced gas desorption represents the lowest current limit at the top energies. However the other two limitations are not far away and they depend on the proper adjustment of many machine parameters

    The ISR results on the differential cross-sections for pp and anti-pp show unambiguously that the crossing-odd amplitude is still important at very high energies. Comparison of ISR and CERN collider anti-pp data suggests that the crossing-odd amplitude is growing maximally fast with energy. We explore the phenomenological consequences of such a ''maximal odderon'' behaviour at TeV energies

  18. The layered sensing operations center: a modeling and simulation approach to developing complex ISR networks

    Curtis, Christopher; Lenzo, Matthew; McClure, Matthew; Preiss, Bruce

    2010-04-01

    In order to anticipate the constantly changing landscape of global warfare, the United States Air Force must acquire new capabilities in the field of Intelligence, Surveillance, and Reconnaissance (ISR). To meet this challenge, the Air Force Research Laboratory (AFRL) is developing a unifying construct of "Layered Sensing" which will provide military decision-makers at all levels with the timely, actionable, and trusted information necessary for complete battlespace awareness. Layered Sensing is characterized by the appropriate combination of sensors and platforms (including those for persistent sensing), infrastructure, and exploitation capabilities to enable this synergistic awareness. To achieve the Layered Sensing vision, AFRL is pursuing a Modeling & Simulation (M&S) strategy through the Layered Sensing Operations Center (LSOC). An experimental ISR system-of-systems test-bed, the LSOC integrates DoD standard simulation tools with commercial, off-the-shelf video game technology for rapid scenario development and visualization. These tools will help facilitate sensor management performance characterization, system development, and operator behavioral analysis. Flexible and cost-effective, the LSOC will implement a non-proprietary, open-architecture framework with well-defined interfaces. This framework will incentivize the transition of current ISR performance models to service-oriented software design for maximum re-use and consistency. This paper will present the LSOC's development and implementation thus far as well as a summary of lessons learned and future plans for the LSOC.

  9. Representation of potential information gain to measure the price of anarchy on ISR activities

    Ortiz-Peña, Hector J.; Hirsch, Michael; Karwan, Mark; Nagi, Rakesh; Sudit, Moises

    2013-05-01

    One of the main technical challenges facing intelligence analysts today is effectively determining information gaps from huge amounts of collected data. Moreover, getting the right information to/from the right person (e.g., analyst, warfighter on the edge) at the right time in a distributed environment has been elusive to our military forces. Synchronization of Intelligence, Surveillance, and Reconnaissance (ISR) activities to maximize the efficient utilization of limited resources (both in quantity and capabilities) has become critically important to increase the accuracy and timeliness of overall information gain. Given this reality, we are interested in quantifying the degradation of solution quality (i.e., information gain) as a centralized system synchronizing ISR activities (from information gap identification to information collection and dissemination) moves to a more decentralized framework. This evaluation extends the concept of price of anarchy, a measure of the inefficiency of a system when agents maximize decisions without coordination, by considering different levels of decentralization. Our initial research representing the potential information gain in geospatial and time discretized spaces is presented. This potential information gain map can represent a consolidation of Intelligence Preparation of the Battlefield products as input to automated ISR synchronization tools. Using the coordination of unmanned vehicles (UxVs) as an example, we developed a mathematical programming model for multi-perspective optimization in which each UxV develops its own fight plan to support mission objectives based only on its perspective of the environment (i.e., potential information gain map). Information is only exchanged when UxVs are part of the same communication network.

    CERN, the European organization for nuclear research, has just celebrated its fifty years of existence. Its first goal was to counterbalance the migration of physics scientists towards the USA by the creation of a physics laboratory gathering scientists from the different European countries. Today, the CERN's mission has changed and has overcome all the expectations of its founders. In 2008, it will become, with the LHC (Large Hadron Collider), the biggest particle accelerator in the world. The CERN employs about 3000 physicists, engineers, technicians and workers. There is also 6500 people from 80 different countries who use the CERN's facilities during the year. The CERN is controlled by 20 European member states and 6 observer countries, and 20 non-member countries participate to the programs in progress. The CERN's power comes from its international and cosmopolitan spirit. The whole most famous physicists of the world can work together for the progress of science and for a better understanding of matter, of its interactions and of our universe. Two Nobel prices of physics come from the CERN: C. Rubbia and S. Van der Meer in 1983 for the discovery of W{sup +}, W{sup -} and Z{sub 0} bosons, and G. Charpak for the development of particle detectors. One can foresee that the LHC will allow new scientific achievements, like for instance, during experiments for the quest of the famous Higgs boson. It is important also to mention that the CERN has been at the origin of several technological innovations in all technical and engineering domains in the framework of its fundamental physics researches.

  14. Sharing resources@CERN

    CERN Multimedia

    2002-01-01

    The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...

    In a virtualized environment, contextualization is the process of configuring a VM instance for the needs of various deployment use cases. Contextualization in CernVM can be done by passing a handwritten context to the user data field of cloud APIs, when running CernVM on the cloud, or by using CernVM web interface when running the VM locally. CernVM Online is a publicly accessible web interface that unifies these two procedures. A user is able to define, store and share CernVM contexts using CernVM Online and then apply them either in a cloud by using CernVM Cloud Gateway or on a local VM with the single-step pairing mechanism. CernVM Cloud Gateway is a distributed system that provides a single interface to use multiple and different clouds (by location or type, private or public). Cloud gateway has been so far integrated with OpenNebula, CloudStack and EC2 tools interfaces. A user, with access to a number of clouds, can run CernVM cloud agents that will communicate with these clouds using their interfaces, and then use one single interface to deploy and scale CernVM clusters. CernVM clusters are defined in CernVM Online and consist of a set of CernVM instances that are contextualized and can communicate with each other.

    CERN, currently the largest organization in the world for particle physics, was founded in 1954. Originally located in Meyrin, at the outskirts of the city of Geneva in Switzerland, it has with time extended into neighboring France. The Theoretical Study Division of CERN, however, was created already in 1952, i.e., before the official inauguration of CERN. It was situated in Copenhagen. Christian Møller [1] was appointed (part-time) as the Director and there were two full time senior staff members, Gunnar Källén and Ben R. Mottelson. While constructing buildings and accelerators were in progress, an international conference was organized by CERN in the city of Geneva. This “CERN Symposium on High Energy Accelerators and Pion Physics”, 11–23 June 1956, attracted about 250 participants from outside CERN, among them at least 18 Nobel Laureates or future Laureates. Unfortunately, the participants from CERN are not listed in the Proceedings [2]. The conference focused on measuring devices such as bubbl...

    Reyrolle, M.

    1985-01-01

    By adding a new spectrometer at 90 0 in the R608 experiment at CERN (ISR) we can search correlations between some systems of particles fully measured in the forward and transverse directions. The corresponding new electronic trigger, which selects events with momentum above a chosen threshold, is mixed or not to the forward trigger, in order to record correlated or inclusive data from the collisions p-p, p-anti-p, α-α. In the 90 0 spectrometer, we build drift chambers, set before the dipolar magnet. We studied the spatial resolution and the methods to associate tracks before and after this magnet. We developed the method to determine the momenta, by taking account of the variations of the deflecting power: the accuracy of this method is better than O.3%, and the global resolution is about 0.01 P 2 . We proposed also how to identify the particles from time of flight measurements and aerogel cerenkov counters [fr

    2014-01-01

    The “Khiagda” mine in the Republic of Buryatia is the only ISR mine in the world where ore mining is performed in a permafrost region. Its raw material source is deposits of the Khiagdinsky ore field having geological reserves of uranium to 48 thousand tonnes. The ore field is a part of the Vitimsky Uranium ore district with reserves of 100 thousand tonnes. This is the most promising region in Russia where the deposits may be extracted by the ISR technique. Throughout a year, the air temperatures varies from +35 to –50°C. Permafrost is developed everywhere to a depth of 90 m. The Khiagdinsky ore field includes 8 deposits. The ore-bearing paleovalleys down-cut the slopes of the granite rise. The ore accumulations are localised in alluvial sandy water-saturated Miocene deposits overlaying the crust formations of the granite basement. They are overlapped by the cover of basalts and volcanogenic sedimentary deposits. The ore accumulations occurrence under the cover of frozen basalts at the depths 90 to 280 m. Uranium in ores is presented by ningyoite; it is significantly reduced, comprising up to 90-100% U(IV). Mining of such ores by the acidic ISR without an oxidant is of low effectiveness. The orebearing sands are quartz-feldspar and practically noncalcareous. The acid consumption caused by chlorites and montmorillonites is at the medium level, 90 kg/tonne. The ore-bearing deposits, according to the filtration tests, have the filtration coefficient (hydraulic conductivity) of 2.1 (1.4–3.7) m/day and water transmissivity of 50 (24–105) m"2/day. The accumulations are inundated irregularly. In the lower reaches of the paleovalleys, the output of the pumping-out wells varies from 5 to 9 m"3/hour, and in the upper reaches it ranges from 2 to 5 m"3/hour. The temperature of the formation waters is 1 to 4°C. The rigorous climatic conditions, high degree of uranium reduction in ores, complicated hydrogeological conditions and high viscosity of the very cold

  8. RILEM TC ISR Summer 2015 Activity Report

    Energy Technology Data Exchange (ETDEWEB)

    Le Pape, Yann [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)

    2015-08-01

    With aging infrastructures, instances of Alkali Silica Reaction (ASR) and Delayed Ettringite Formation (DEF), broadly covered under the term Internal Swelling Reaction (ISR), are increasingly being detected. They have been observed in bridges, dams, and most recently in nuclear power plants. Concrete swelling may result in bridge partial failure, dams with structural cracks and misaligned turbine shafts, and locked slice gates. For nuclear reactors micro-cracks may cause increased gas permeability which will jeopardize the containment integrity and may decrease the residual structural resistance under accidental loading. This TC, which limits its activity to structures with known expansive concrete, seeks to address two complementary but fundamental questions: a) What is the kinetics of the reaction and b) How would it affect the integrity of the structure (serviceability and strength) and thus establish a science based prognostic to the structure owner.

  10. Structure of events with a particle at large transverse momentum in proton-proton collisions at the CERN ISR

    International Nuclear Information System (INIS)

    Herr, W.F.

    1985-01-01

    The structure of events with a particle with large transverse momentum has been studied for proton-proton collisions at a centre-of-mass energy of √s=62.2 GeV. The experiment was performed with the Split-Field-Magnet detector at the CERN Intersecting Storage Rings and events were recorded with high-psub(T) particles with psub(T)>2 GeV/c produced at polar angles around 45 0 and 20 0 . The distributions of charged particles in the jet recoiling against the high-psub(T) particle have been measured as a function of the fragmentation variable xsub(E)=psub(T)/psub(T)sup(tri). The production of high-psub(T) particles is usually interpreted in the quark parton model as the hard collision of proton constituents. The asymmetry and charge composition of the recoil jet and their correlation with the flavour of the high-psub(T) particle supports this qualitative picture. Model calculations using first order Quantum Chromodynamics (QCD) and phenomenological fragmentation model cannot explain the particle distribution in the recoil jet. (orig.) [de

    Art students inspired by CERN will be returning to show their work 9 to 16 October in Building 500, outside the Auditorium. Seventeen art students from around Europe visited CERN last January for a week of introductions to particle physics and astrophysics, and discussions with CERN scientists about their projects. A CERN scientist "adopted"each artist so they could ask questions during and after the visit. Now the seeds planted during their visit have come to fruition in a show using many media and exploring varied concepts, such as how people experience the online world, the sheer scale of CERN's equipment, and the abstractness of the entities scientists are looking for. "The work is so varied, people are going to love some pieces and detest others," says Andrew Charalambous, the project coordinator from University College London who is also curating the exhibition.

    CERN Multimedia

    1974-01-01

    The Split-Field Magnet (SFM) at I4 had an unconventional topology, consisting of two dipole magnets of opposite polarity. It formed the heart of the first general facility at the ISR. It had a useful magnetic field volume of 28 m3 and a field in the median plane of 1.14 T. With a gap height of 1.1 m and length of 10.5 m, the magnet weighed about 1000 t. The SFM spectrometer featured the first large-scale application of MWPCs (about 70,000 wires), which filled the main magnet, visible here in 1974, and the two large compensator magnets.

  1. Precise Measurement of the $\\bar{p}p$ Total Cross-Section in the ISR Energy Range

    CERN Multimedia

    2002-01-01

    The major aim of this experiment is the precise measurement of the antiproton-proton total cross-section in the ISR energy range, using the total-rate method. The proton-proton total cross-section is remeasured with the same method and the same apparatus, and a precision of 0.5\\% is expected for both cross-sections. The total-rate method consists in the simultaneous measurement of the total interaction rate and the ISR luminosity. This is done with a set of scintillation-counter hodoscopes covering over 99.99\\% of the solid angle, which are sensitive to over 95\\% of all interactions. In addition to these detectors, small-angle drift-tube hodoscopes are used to measure the differential elastic cross-section as a function of the momentum transfert t. The total cross-section can be measured independently by extrapolating this differential cross-section to the forward direction and invoking the optical theorem. A study of the general features of charged-particle production is performed using finely divided scinti...

He was a professor at the Scuola Normale Superiore in Pisa and spent most of his scientific career at CERN.   Lorenzo Foà (left) in front of the ALEPH detector, 2001. He is photographed with Jack Steinberger (centre) and Pierre Lazeyras (right). In the early 1960s Lorenzo was among the proponents of two experiments that allowed the first measurements of π0 and η lifetimes via the Primakoff effect at Frascati and then at DESY. Later he joined the CERN-Orsay-Pisa Collaboration, studying polarisation in hadron scattering, and then the Pisa-Stony Brook Collaboration at the CERN ISR. This experiment discovered that the total proton-proton cross section starts increasing at ISR energies, a departure from what had previously appeared to be a flat “asymptotic” beha...

  5. Keeping particle physics lively, stimulating, and maybe more…

    CERN Multimedia

    2011-01-01

    A recurring theme at last week's Council meetings was the request I received to pass on Council’s heartfelt thanks to all the CERN community for the successful period we are currently enjoying, and it is my pleasure to do so. Council's request also serves as a timely reminder that CERN is more than the LHC, and the LHC is more than the machine and its four big experiments.   Earlier this week, one of the smaller LHC experiments, TOTEM, published its first results. TOTEM's paper contains measurements that are vital for a full understanding of hadron collider physics, as well as for topics in particle astrophysics. They continue a CERN tradition that goes back to the world's first hadron collider, CERN’s Intersecting Storage Rings (ISR). One of the most significant results from the ISR was the unexpected observation that the cross-section for proton-proton collisions rises with energy. Put another way, it appears that the proton gets larger t...

    Simple statistical simulation algorithms are suggested for formation and breaking of a few quark-gluon strings in inelastic pp collisions. Theoretical multiplicity distributions, semi-inclusive quasirapidity spectra, forward-backward correlations of charged secondaries and seagull effect agree well with the experimental data at ISR energies. In the framework of the model, the semi-inclusive two-particle correlations of quasirapidities depend upon the fraction of the spherical chains. The seagull effect is qualitatively interpretated

    In 1961, based on the finding that the evolution of the labour market created a growing need for qualified staff, a first agreement between the Republic and Canton of Geneva and CERN was signed. One of the objectives of this agreement was the vocational training of young electronics and physics laboratory technicians. CERN, an important stakeholder in the local economy, highlighted with this agreement its willingness to participate in the local social and economic development. The first apprentice arrived at CERN in 1965. In 1971, the apprenticeship centre was created; it now hosts over twenty apprentices in total and welcomes about six new apprentices each year. These apprenticeships are for young people aged between 15 and 21 years, coming from one of the CERN Member States, and having completed their mandatory education, e.g. 11th grade in Switzerland or 3ème in France.

  18. RSS based CERN Alerter. Information broadcast to all CERN offices.

    CERN Multimedia

    Otto, R

    2007-01-01

    Nearly every large organization uses a tool to broadcast messages and information across the internal campus (messages like alerts announcing interruption in services or just information about upcoming events). These tools typically allow administrators (operators) to send "targeted" messages which are sent only to specific groups of users or computers, e/g only those located in a specified building or connected to a particular computing service. CERN has a long history of such tools: CERNVMS€™s SPM_quotMESSAGE command, Zephyr and the most recent the NICE Alerter based on the NNTP protocol. The NICE Alerter used on all Windows-based computers had to be phased out as a consequence of phasing out NNTP at CERN. The new solution to broadcast information messages on the CERN campus continues to provide the service based on cross-platform technologies, hence minimizing custom developments and relying on commercial software as much as possible. The new system, called CERN Alerter, is based on RSS (Really Simpl...

    In its continual tour of CERN Member States, the European Committee for Future Accelerators (ECFA) visited Lisbon, Portugal, on 21-22 April, where it met at the Instituto Superiore Tecnico, a technical university with 9,000 students. Portuguese particle physics is in a particularly healthy situation, having developed considerably following Portugal's admission to CERN in 1985. With support from Brussels, scientific infrastructure has developed rapidly, although the science base has yet to attain the levels seen in larger nations. The 45-strong population of experimentalists in Portugal, including 14 PhDs, represents a 2.5-fold increase since Portugal joined CERN ten years ago and is in line with the goal stated at the time. This successful development of experimental particle physics has benefited much from physicists returning from abroad (mainly France and the UK). The direct result of the efforts of a few individuals (notably J.M. Gago), this splendid achievement provides an excellent role model for new and potential CERN Member States. At present, particle physics represents some 3 0% of all Portuguese physics publications. This very special role (and the financial support it implies) provides a visible target, but one which can be defended as it provides a catalyst for other national scientific developments. The national hub is the Laboratory for experimental high energy physics and related R&D projects (LIP), with centres in Lisbon (Head, J.M. Gago) and Coimbra (Head, A. Policarpo). LIP, with close links to two universities in Lisbon and to the University of Coimbra, has developed into a centre of expertise and training in electronics, computing and software engineering. Present LIP funding is some 2 million Swiss francs/year (70% in Lisbon and 3 0% in Coimbra), covering most of the salaries of the nonuniversity people, the remainder being supported by grants from Portuguese and European programmes.

    Israel (along with the US, Japan, Canada, the Russian Federation and India) is one of the CERN non- Member State nations targeted for substantial future participation in CERN's experimental programme, in particular for the LHC proton collider to be built in the 27-kilometre LEP tunnel and which was formally approved by CERN Council in December (January/February, page 1). In keeping with their illustrious scientific traditions, Israeli experimental physicists have collaborated in experiments at many of the world's major high energy Laboratories - Brookhaven, Fermilab and SLAC in the US, and in Europe, DESY, Hamburg, as well as CERN. However CERN, as the geographically closest major Laboratory (as well as the largest), plays a special role for Israeli scientists. At CERN, the advent of preparations in the early 1980s for the experimental programme at the LEP electron-positron collider was the signal for Israeli researchers to mount a concerted effort and contribute to one of the experiments - Opal - at a level comparable to that of major nations. This allowed Israeli teams to participate fully in the planning and construction phase of this branch of Big Science. Underlining this commitment, and to coordinate the various national agencies involved in this aspect of Big Science, in 1983 the Israel Commission for High Energy Physics (ICHEP) was formed. It is currently chaired by David Horn of Tel Aviv. The initial ICHEP/CERN contract established the official CERN/lsrael link under which, in the short-term, teams from three major research centres - the Weizmann Institute, Tel- Aviv University, and Haifa's Technion - contributed to Opal, as the flagship experiment, while providing a framework for longer-term collaboration. (At CERN, Israeli physicists also participate in the NA45 heavy ion experiment and the NA47 Spin Muon Collaboration - SMC.) Opal groups some 320 scientists from 32 research centres in eight countries, and includes a 21-strong Israeli

    1999-01-01

    A preliminary full size test of a simplified version containing some relevant elements of the CMS (compact muon solenoid) Link Alignment System has been installed in an experimental area of the ISR (interaction storage ring) tunnel at CERN. Previously a calibration bench was prepared with standard precise survey methods. The environmental conditions, temperature, atmospheric pressure and relative humidity in the hall were controlled revealing quite stable conditions all along the tests period. The stability measurements done under these conditions show that the light spot on sensors located at about 6 m from the light source are smaller than 5 μm, which satisfies the requirements. Induced changes in the environmental conditions have different effects. Air flows degrades significantly the spatial resolution (∼5μm) but the background due to the environmental light does not degrades the resolution in position reconstruction. A geodesic network defines a reference system common to all opto-mechanical components and can be used to do absolute measurements of the angle between the two light beams coming out from the splitter. The accuracy in the reconstruction of angles with the help of the geodesic network depends on the errors in the network definition. These errors propagate with a smaller or larger strength depending on the distances between the network points. In our tests, the accuracy in the angle reconstruction is 14 μrad when using 4 in and 5.9 m long arms and 17 μrad for 4 m and 2.9 m arms. We found a precision 4 μrad in the angular reconstruction.

As part of this exchange, CERN Director-General Rolf Heuer wrote a message in DESY inForm. Helmut Dosch took over from Albrecht Wagner in March 2009. You may think that the connections between CERN and DESY are obvious – particle physics labs with record-breaking accelerators and users from all around the world trying to solve mankind’s great mysteries. We even exchanged a few Directors. But did you know that there are similarities that are much closer to home – for example that both labs have names for their staff in the host language that are untranslatable into English? You are CERNoises and CERNois, we are DESYanerinnen and DESYaner. And in the end it’s the people it all comes down to. We at DESY admire the resourcefulness, enthusiasm, dedication and perseverance with which you at CERN have designed, built, started ...

    Since the beginning of 2009, due to the CERN restructuring, LabVIEW support moved from the IT to the EN department, joining the Industrial Controls and Electronics Group (ICE). LabVIEW support has been merged with the Measurement, Test and Analysis (MTA) section which, using LabVIEW, has developed most of the measurement systems to qualify the LHC magnets and components over the past 10 years. The post mortem analysis for the LHC hardware commissioning has also been fully implemented using LabVIEW, customised into a framework, called RADE, for CERN needs. The MTA section has started with a proactive approach sharing its tools and experience with the CERN LabVIEW community. Its framework (RADE) for CERN integrated application development has been made available to the users. Courses on RADE have been integrated into the standard National Instruments training program at CERN. RADE and LabVIEW support were merged together in 2010 on a single email address:labview.support@cern.ch For more information please...

  16. CERN's technical apprentices during their apprenticeships

    2004-01-01

    CERN starting training apprentices in 1966 at the request of the Geneva authorities. The programme was consolidated with the opening of the training centre in 1971. In recent years CERN has taken on seven new technical apprentices each year (four in electronics, three in physics laboratory work), plus one or two administrative apprentices, such that there always are around 30 apprentices in total at CERN. The programme is highly regarded in Geneva by the authorities, industry, schools and young people, and contributes very positively to CERN's local image. Since the beginning 160 young people have now successfully completed their apprenticeships at CERN. Unlike some other employers, as a general rule CERN does not take on its ex-apprentices as staff; on completing their years at CERN the apprentices usually go on to higher education or are sought after by other employers.

    1999-04-15

    As a consequence of changes in the administrative structure of TIS Division in 1996 and 1997, the Environmental Section was integrated into the TIS Technical Services and Environment Group that also looks after the non-radiation parameters in the CERN releases and environment. However, it remains the duty of the Radiation Protection Group (RP) to define the environmental programme for radiation and radioactivity, and of the leader of RP to report its results both inside and outside CERN. Part I of this Annual Report describes the results of measurements which are relevant for assessing the radiological impact of CERN's activities on the environment and the population living in the vicinity of the CERN sites. Measurements of radioactivity released into the atmosphere and into water, as well as measurements of stray radiation at or near the CERN site boundaries, are reported.

    1986-01-01

    A condensed version is given of CERN report ''Economic utility resulting from CERN contracts'' by the same authors, which attempts to quantify the economic benefit to high technology manufacturing industries involved in CERN contracts, in relation to their sales to CERN. It covers the period 1973 to 1987 and complements an earlier study made in 1973-1975. Interviews were carried out in 166 European firms of which the majority supplied estimates of increased sales and cost savings due to CERN contracts. This ''economic utility'' totals 3107 million Swiss francs (up to the year 1987) compared to sales to CERN in 1973 to 1982 amounting to 748 million Swiss francs in 1982 prices. It is estimated that, by 1987, CERN's high technology purchases made in 1973 to 1982 will have generated economic utility amounting to about 60% of the overall cost of the organization during the same period.

    2002-01-01

    Kurt Hübner will long be remembered at CERN for his leadership in the accelerator field during his 38 years of service to it. A brilliant, conscientious and determined physicist, he has always been known for his humility and humanity. He retired from CERN on 29th November. Kurt Hübner, who is Austrian, joined CERN in 1964 as a fellow, to work on the CESAR electron storage ring project for the ISR. He became a member of the personnel in 1966 and joined the ISR Division two years later. At the end of the 1970s he played an important role in the design studies for LEP, in particular proposing that the existing synchrotrons be used as the injectors for the new collider. It was therefore logical that he should take on the responsibility for designing the LEP injector chain from 1983 onwards. In addition to his involvement in the commissioning and operation of the collider, he took part in drawing up the proposals for the LHC and in the studies for CLIC, the project for a future linear collider...

    To mark International Women's Day on 8 March, the Weekly Bulletin has looked at the careers of six female physicists, engineers and administrators working at CERN. A frequent question on the lips of newcomers to CERN as they take a quick look around them is 'But where are the women?' However, while it's true that the Laboratory has never had a huge number of female personnel, a closer look reveals that there are in fact quite a few around. To mark International Women's Day, the Bulletin has interviewed six women working at CERN to find out how they see the Organization, what they do and what they think about their daily working lives. Creating a link 'Maybe because I grew up during World War II, my parents always taught me to respect people of other nationalities, religions, colour, etc., so one thing I have always appreciated about CERN is that it promotes this tolerance and understanding by giving us the great privilege of working side by side with colleagues from many cultures and walks of life.'

    CERN is actively making its knowledge and technology available for the benefit of society and does so through a variety of different mechanisms. Open hardware has in recent years established itself as a very effective way for CERN to make electronics designs and in particular printed circuit board layouts, accessible to anyone, while also facilitating collaboration and design re-use. It is creating an impact on many levels, from companies producing and selling products based on hardware designed at CERN, to new projects being released under the CERN Open Hardware Licence. Today the open hardware community includes large research institutes, universities, individual enthusiasts and companies. Many of the companies are actively involved in the entire process from design to production, delivering services and consultancy and even making their own products available under open licences.

    What do CERN and other scientific organizations like ESA and ESO have in common with neurosurgery and airlines? At first sight, not much. But all require sound safety management. CERN's expertise in this field was recently highlighted when two CERN engineers were invited to talk at an international conference on Quality Management and Risk Control in Neurosurgery.CERN has long been recognised as a centre of excellence in physics, and its spin-offs in fields such as medicine have been widely hailed. But increasingly, the Laboratory's expertise in the management of large international collaborations is also being recognised. Contacts between CERN and organizations like ESA and ESO, as well as with industry, bear witness to this fact. One recent example comes from Airbus Industrie, which organized a meeting in 1998 with CERN to compare notes on project management, safety, and quality assurance. Safety management is a recognised speciality in the field of project management and at CERN, TIS and the safety offici...

In honour of the publication's 50th anniversary, we're taking a trip through CERN’s history via the headings and hidden corners of its internal newsletter.     It's 1965 and CERN - now 11 years old - has matured from a simple lab to a fledgling community. While news could once spread in a single afternoon, CERN's growth necessitated a new approach to the sharing of internal information. Meanwhile, the CERN Courier - the only publication in town - was approaching a more global physics audience – an audience for whom CERN road closures were not breaking news. And so, in March 1965, the Weekly Bulletin was born. What was meant as a simple newsletter of events and internal announcements quickly developed into a wider source of news about CERN....

  1. Comparison of Vertical Drifts of ISR and Magnetometer Data Measurements at the Magnetic Equator

    Science.gov (United States)

    Condor P, P. J.

    2014-12-01

    We compare vertical drifts measured with the Jicamarca incoherent scatter radar (ISR) and drifts estimated from magnetometer data applying a Neural Network data processing technique. For the application of the Neural Network (NN) method, we use the magnitude of the horizontal (H) component of the magnetic field measured with magnetometers at Jicamarca and Piura (Peru). The data was collected between the years 2002 and 2013. In training the NN we use the difference between the magnitudes of the horizontal components (dH) measured at JRO (placed at the magnetic equator) and Piura (displaced 5° away). Additional parameters used are F10.7 and Ap indexes. The estimates obtained with the NN procedure are very good. We have an RMS error of 3.7 m/s using dH as an input of the NN while the error is 3.9 m/s when we use the component H of JRO as an input. The results are validated using the set of vertical drifts observations collected with the Jicamarca incoherent scatter radar. The estimated drifts can be accessed using the following website: http://jro.igp.gob.pe/driftnn. In the poster, we show the comparison of vertical drifts from 2002 to 2013 where we discuss the agreement between magnetometer and ISR data.

    1987-01-01

    The paper examines the future of CERN, with respect to its proposed research programme and its need to save money. Proposals concerning what accelerators CERN should build for the future are outlined; machines such as the Large Hadron Collider and the CERN Linear Collider have been proposed. Experimental expectations for the first Large Electron Positron (LEP) collider (now close to completion) are briefly described, along with the experimental investigations for the second phase of operation of LEP where modifications will increase the machine's energy. Criticisms of CERN's management by its governing body are also discussed. (UK)

  5. CERN, the US and the W

    CERN Document Server

    Crease, Robert P

    2004-01-01

    In 1983, CERN physicists discovered the W boson earning them the first Nobel prize. This discovery served as the turning point for CERN from the point of view of the self-confidence of its physicists, the confidence of its fund-raisers, and its reputation in the US. However, this feat did not come as easy for CERN. Rivalry with the US revealed complexities. Nevertheless in the end, CERN physicists became the more successful. Recognizing this, US physicists agreed to collaborate with CERN physicists. Today, there is no more political competition over accelerators between the two groups. (Edited abstract).

  8. Industrial Activity at CERN

    CERN Document Server

    Kowalik, G

    2000-01-01

    The decrease in the number of CERN staff creates the need for optimization of the non-core, infrastructure-related activities. An industrial, service-orientated approach has long been considered as an appropriate way to cope with the problem of diminishing resources. This paper presents industrial and service activity issues at CERN based on the experience of the exploitation of the power network. The most important problems linked to the application of the industrial approach to the exploitation of equipment in the CERN research environment are covered. These include the interface between accelerators and electrical exploitation services, external and internal regulations, sharing of responsibility between CERN staff and external contractors, continuous modification of clients' requirements, the balance between the cost of accelerator downtime versus the cost of infrastructure upgrade. A benchmarking through a comparison with a big industrial manufacturer is followed by recommendations for possible improveme...

    The picture shows the part of the "Flat-Fish" chamber covering one side of the beam intersection region. The other side is covered by an equal part and both are welded toghether at their small end. The two shells of each part were hydroformed from 0.15 mm thick inconel 718 sheet (with end parts in inconel 600 for easier manual welding to the arms) and welded toghether with two strips which were attached by means of stainless steel strings to the Split Field Magnet poles in order to take the atmospheric pressure forces. This was the thinnest vacuum chamber made for the ISR. Inconel material was chosen for its high elastic modulus and strenght at chamber bake-out temperature.

    The newest phase of CERN’s openlab framework was inaugurated this week during a meeting of the openlab partners. This phase will last three years and will bring together existing openlab partners and a new contributor: Huawei.   Group picture taken at the first CERN openlab IV annual Board of Sponsors meeting, in the presence of the CERN Director-General, the partners and the openlab team members. © Fons Rademakers (CERN Photo Club). Eleven years ago, the creation of the CERN openlab created a long-term link between industrial partners and the Organization. Its framework has allowed industry to carry out large-scale IT research and development in an open atmosphere – an “Open Lab”, if you will. For CERN, openlab has contributed to giving the computing centre and, more broadly, the LHC community, the opportunity to ensure that the next generation of services and products is suitable to their needs. Now entering its fourth phase, openlab will ...

  4. CERN and ESA: fundamentally contrasting organisations?

    International Nuclear Information System (INIS)

    Bowell, Valerie

    1988-01-01

    The paper concerns the European Organisation for Nuclear Research (CERN) and the European Space Agency (ESA), and questions whether the United Kingdom (U.K.) will continue as a full member of these two organisations. A description is given of the establishment of these institutions, their collaboration and their activities. The effect of the U.K.'s financial difficulties on both CERN and ESA programmes is discussed. Figures are given on the actual cost to the U.K. of CERN and ESA, and also the CERN and ESA subscriptions as a percentage of total spending on particle physics and astronomy, for the period 1980-8. The U.K. committment to the ESA and CERN programmes are both described. (U.K.)

    1979-01-01

    Inclusive π 0 production at 90 0 has been studied at the ISR at ssup(1/2) = 52.7 and 62.4 GeV over the psub(T) range from 7 to 15 GeV/c. The two photons from π 0 decay yielded overlapping electromagnetic showers in the liquid-argon-Pb plate calorimeter detector system. Any direct photon production is included in these measurements. For large values of psub(T), the cross section is observed to decrease with psub(T) more slowly than the psub(T) -8 behaviour which has been observed at lower values of psub(T). (Auth.)

    CERN communicates with the outside world in many different ways – websites, publications, through the media and via twitter to name but a few. As of January, CERN has a new way of engaging with the world: a CERN institutional blog.   CERN’s blog was launched on 10 January on the Quantum Diaries platform, adding a new strand to a well-established site. Quantum Diaries was launched in 2005 as an initiative for the World Year of Physics promoted by the InterAction collaboration, a group that brings together the communication offices of some of the world’s major particle physics labs and organisations. The launch of institutional blogs from Brookhaven, CERN, Fermilab and TRIUMF has added an extra dimension to Quantum Diaries. Visits to the site jumped to 3000 per day with the addition of the institutional blogs, and that number is already growing. CERN’s first post explains one of the reasons we’re doing this.

  14. CERN and space science

    CERN Multimedia

    2009-01-01

    The connection between CERN and space is tangible this week, as former CERN Fellow and ESA astronaut Christer Fuglesang begins the second week of his mission on space shuttle flight STS-128. I had the pleasure to meet Christer back in October 2008 at an IEEE symposium in Dresden, and he asked me whether we could give him something related to CERN for his official flight kit. We thought of caps and tee-shirts, but in the end decided to give him a neutralino as a symbol of the link between particle physics and the science of the Universe. Neutralinos are theoretical particles that the LHC will be looking for, and if they exist, they’re strong candidates for the Universe’s dark matter. Christer’s neutralino is just a model, of course, escaped from the particle zoo, but what better symbol of the connectedness of science? Christer Fuglesang is not the only link CERN has with the space shuttle programme. We’ve recently learned that...

    The CERN Library Information desk.At a meeting on the Wednesday before Easter, the Executive Committee endorsed a policy of open access to all the laboratory's results, as expressed in the document ‘Continuing CERN action on Open Access' (http://cds.cern.ch/record/828991/files/open-2005-006.pdf), released by its Scientific Information Policy Board (SIPB) earlier in the month. "This underlines CERN's commitment to sharing the excitement of fundamental research with as wide an audience as possible", said Guido Altarelli, current SIPB chairman. Open Access to scientific knowledge is today the goal of an increasing component of the worldwide scientific community. It is a concept, made possible by new electronic tools, which would bring enormous benefits to all readers by giving them free access to research results. CERN has implicitly supported such moves from its very beginning. Its Convention (http://cds.cern.ch/record/330625/files/cm-p00046871.pdf), adopted in 1953, requires openness, stipulating that "......

    1993-01-01

    CERN's long and distinguished neutrino tradition began in 1958 at the then new 500 MeV synchrocyclotron (SC) with the first observation of the decay of a charged pion into an electron and a neutrino. At that time, the first ideas on the special (vector/axial vector) structure of the weak interactions had been put forward by Feynman and Gell-Mann and by Marshak and Sudarshan, but the continual non-observation of that charged pion decay was holding up progress. This decay is only one part in ten thousand, and is masked by the dominant muon-neutrino channel. A special telescope was built to pick up the high energy electrons from the pion decay. In 1962 came another SC neutrino success, with the first measurement of the decay of a charged pion into a neutral one, with emission of an electron and a neutrino. Meanwhile the main thrust of CERN's neutrino effort was taking shape at the PS. By the close of 1960, CERN had decided to attack neutrino physics using several detectors - a 1m heavy liquid bubble chamber from Andre Lagarrigue's team in Paris, a CERN 1 m heavy liquid bubble chamber, and a hybrid chamber/counter from a group led by Helmut Faissner

    Firemen from local fire brigades have been coming to CERN to learn modern fire-fighting techniques. The CERN fire brigade has some unique training equipment for two particularly dangerous fire hazards, flashover and backdraft. Flashover occurs when a room that is on fire reaches a temperature of 400 to 500°. Beyond this point, a fully developed fire breaks out. This series of photos shows recruits from the fire services of Ain (Service Départemental Incendie et Secours (SDIS)) taking part in a flashover training exercise at CERN.

    Burckhart, H; Schmid, P; Schuh, S

    Celebrating its 50 years of existence, its achievements and to communicate its plans for the future, CERN is organizing an "Open Day" on Saturday 16 October 2004. This will be a major event for CERN's public relations; some 10000 visitors from near and far are expected to follow CERN's invitation. ATLAS has to, and will, play its role on this occasion. A small group of people (H. Burckhart, C. Potter, P. Schmid and S. Schuh) from the CERN ATLAS Team is acting as interface to CERN's organizing committee. This is all done in close collaboration with the ATLAS Outreach Coordinators. According to our present plans ATLAS will organize three visit sites: - The ATLAS "headquarters" will be in the future ATLAS control room at the pit. We shall show films (ATLAS specific and general HEP), distribute information material, sell our scarves, ties, T-shirts and watches, explain ATLAS in as many languages as we can and - most likely the major attraction - give the visitors the possibility to go down into the cavern. - ...

    In early September, GridPP, the collaboration that manages the UK’s contribution to the worldwide LHC Computing Grid (wLCG), celebrated a decade of work by holding its twenty-seventh collaboration meeting at CERN.   Officially launched in September 2001, GridPP was one of the original partners in wLCG, funding much of the early work at CERN. Over the last decade GridPP has gone from a mere proposal to almost 30,000 CPUs working for researchers scattered across the globe. Twice a year, GridPP meets to discuss the progress and future plans of the community and this year, for the first time since 2004, decamped to CERN for this biannual meeting on the theme “GridPP in the International Context”. The main meeting was held over 2 days in the IT auditorium and was the perfect opportunity to have contributions from experts based at CERN, alongside those from within GridPP. Opening with a welcome from Frederic Hemmer, Head of the IT Department at CERN, the meeting began with...

    Stephen Hawking visiting the CERN Control Centre.If you happened to pass through Building 4 during the first weeks of September, you might have noticed the name of Stephen Hawking on one of the doors on the second floor, which hosts most of CERN theorists’ offices. Three years after his last visit to CERN, Stephen Hawking gladly accepted the invitation from the University of Geneva to hold a public lecture on the occasion of its 450th anniversary and requested an office at CERN for the length of his stay. The "master of the Universe", as the Geneva University journal dubbed him, attracted over 4000 people to his lecture on "The Creation of the Universe" held on 15 September in the Main Auditorium of Uni Dufour. His more technical colloquium on the same subject at CERN a week earlier, was no less popular and quite "provocative" according to some of the physicists in the audience. With his repeated reference to the "non-need" for a "creating agent" for the Universe, mo...

  4. New spam-detection engine for CERN mailboxes

    CERN Multimedia

    The flow of spam (unsolicited e-mail) targetting CERN mailboxes is constantly increasing: 96% of the 2.5 million mails received daily at CERN consist in successfully filtered spam, but spammers get smarter and detecting spam is becoming ever more difficult. In order to address this evolution, a new spam-detection software engine will progressively be deployed starting from 15 April 2008. It will not affect how CERN users currently deal with spam: the spam configuration page, the 'CERN Spam' folder and the Outlook 'report spam' button will continue to work exactly as before. Because spam detection is based on probabilities, some legitimate messages can sometimes be incorrectly detected as spam. We invite all users of CERN mailboxes to regularly check their 'CERN spam' folder for such messages. To prevent incorrect filtering of legitimate messages, it is possible to set up a whitelist (list of trusted e-mail addresses that bypass the spam filter) and adjust the spam filtering level from the CERN mailbox confi...

    2009-01-01

    With a strong curiosity for the work of CERN, HSH Prince Albert II of Monaco visited CMS and the CERN Control Centre on 2 September. "The Prince is interested in and sensitive to what CERN is doing. Monaco is closely linked to France, which is an important member of CERN. He wishes to express his help to the scientific community in every trip. He wants to meet scientists and to be really personally involved," explained Francois Chantrait, Head of the Press Service of the Prince’s Palace. CERN Director-General Rolf Heuer welcomed the Prince of Monaco to Point 5 with a presentation about CERN before they descended 100 metres underground to see the CMS experiment. Although the detector was closed up for test runs, he was able to see its grand scale as well as look at some of the intricate sample parts exhibited by CMS Spokesperson, Jim Virdee. The Prince wrote in the CERN Visitors’ Book that he perceives a realisation of promisin...

  6. Internet Access from CERN GSM subscriptions

    CERN Multimedia

    2008-01-01

    The data service on GSM subscriptions has been improved, allowing CERN users to access the Internet directly. A CERN GSM subscription with data option now allows you to connect to the Internet from a mobile phone or a PC equipped with a GSM modem. The previous access (CERN intranet) still exists. To get access to the new service, you will find all the information on configurations at: http://cern.ch/gprs The use of this service on the Sunrise network is charged on a flat-rate basis (no extra charge related to the volume of downloaded data). Depending on your CERN subscription type (standard or master), you can also connect to foreign GSM data networks (roaming), but this is strongly discouraged, except where absolutely necessary, due to international roaming charges.

  8. Production of charmed mesons and charmed baryons at the ISR

    International Nuclear Information System (INIS)

    Geist, W.M.

    1980-01-01

    Although many experiments were dedicated to charm search in hadronic interactions no significant signals were found until recently. This is why no consistent picture for charmed particle production could be extracted from the data so far. After the first observation of D + production by the CCHK-Collaboration, the obvious aim is to learn more details about the dominant production mechanisms of this new flavour. The observation of charmed baryon production at the ISR by the CCHK and two other collarborations constitutes another major step forward in this field. Here, the two experiments performed by CCHK with the Split Field Magnet (SFM) will be described, in which charmed meson production and charmed (anti)-baryon production were observed. Cross sections will be presented and consequences of the results will be discussed

    2011-01-01

    During more than 50 years of existence, CERN’s well-known magazine has changed several times in appearance. Now, for the first time since the 1990s, it has a new look for the new decade.   The new cover of the CERN Courier. Originally conceived as an internal newsletter, the CERN Courier first appeared in August 1959 in an edition of 8 pages with a print run of 1000. From the start it generated interest outside CERN, with its articles not only on CERN but also about particle physics around the world. The number of copies doubled in the first 6 months in response to the external demand. As CERN prepares to welcome new Member States in the coming years, it’s even more fitting that the magazine should continue to address a global readership, now totalling some 25,000 and extending throughout the many countries that have an interest in particle physics. It’s therefore important that the CERN Courier should remain appealing to this extensive audience, both visually and i...

    It's getting hot in Buildings 201 and 860, over-heating even... But no reason to panic! We're talking about the superheated water boilers of CERN's two heating plants, which heat all the buildings on the Meyrin and Prévessin sites.   View of the three boilers and the control centre of the Meyrin heating plant. CERN's two heating plants each comprise three gas* boilers, with generators of 15 MW in the case of Meyrin and 5 MW in the case of Prévessin. Both inject pressurised water, superheated to 125 degrees, into several kilometres of pipes, 22 km on the Meyrin site and 5 km in Prévessin. "A single boiler is sufficient most of the time but a second kicks in automatically during very cold weather, and a third is there on stand-by," explains Christophe Martel, head of the GS Department section responsible for CERN's heating and air-conditioning systems. All of CERN's buildings have a sub-station that receives the superheated water from the boilers an...

    Do you like listening to music while working? What about watching videos during leisure time? Sure this is fun. Having your colleagues participating in this is even more fun. However, this fun is usually not free. There are music and film companies who earn their living from music and videos. Thus, if you want to listen to music or watch films at CERN, make sure that you own the proper rights to do so (and you have the agreement of your supervisor to do this during working hours). Note that these rights are personal: You usually do not have the right to share this music or these videos with third parties without violating copyrights. Therefore, making copyrighted music and videos public, or sharing music and video files as well as other copyrighted material, is forbidden at CERN --- and also outside CERN.

  15. Environmental radiation monitoring on the CERN sites and in the CERN environment during 1997

    Energy Technology Data Exchange (ETDEWEB)

    Vojtyla, P; Wittekind, D

    1998-04-10

    As a consequence of changes in the administrative structure of TIS Division in 1996 and 1997, the Environmental Section was integrated into the TIS Technical Services and Environment Group that also looks after the non-radiation parameters in the CERN releases and environment. However, it remains the duty of the Radiation Protection Group to define the environmental programme for radiation and radioactivity, and to report its results both inside and outside CERN. In 1997, the environmental programme was slightly modified after discussions with the Sektion zur Ueberwachung der Radioaktivitaet (SUeR) in Fribourg. Gamma spectroscopy analyses of moss and water plants collected once per year in the rivers l'Allondon, Le Lion, Le Nant d'Avril and La Versoix were added. Moss and water plants were chosen as they are sensitive indicators of the presence of natural and man-made radioactivity in the environment. Part I of this Annual Report describes the results of measurements which are relevant for assessing the radiological impact of CERN's activities on the environment and the population living in the vicinity of the CERN sites.

  18. A brief history of CERN

    International Nuclear Information System (INIS)

    Jacob, M.

    2004-01-01

    This article draws a brief history of CERN that has just celebrated its jubilee. Today 20 member states contribute to its annual budget that reached 650 million euros in 2004. In 1954 CERN was created by 12 founder states for mainly 3 reasons: 1) to achieve a research facility dedicated to particle physics able to compete with its American counterparts and that no European country could afford alone, 2) to generate with scientific research an example and a promoter for future international collaborations, and 3) to make scientists from different countries that were at war a few years before, to work together. The creation of CERN has not led to a decline of national laboratories as it was feared in the fifties. On the contrary scientific and technical tasks have been dispatched: CERN provides member states with accelerator facilities while national laboratories and universities contribute to the design and fabrication of detectors and to the analysis of experimental data. The history of CERN is marked by 2 main scientific milestones, first the discovery of weak interaction through neutral currents in 1973 and secondly the discovery of W and Z bosons in 1983. (A.C.)

    Summer is coming - and with it, a new Microcosm exhibition showcasing CERN (see here). But while the new exhibit is preparing to enchant visitors, many have been asking about the site's former content. Will it simply be out with the old and in with the new? Not as such!   The plasma ball from Microcosm is now on display at the LHCb site. As Microcosm's new content is moving in, its old content is moving up. From LHCb to IdeaSquare, former Microcosm displays and objects are being installed across the CERN site. "Microcosm featured many elements that were well suited to life outside of the exhibition," says Emma Sanders, Microcosm project leader in the EDU group. "We didn't want this popular content to go to waste, and so set out to find them new homes across CERN." The LHCb experiment has received a number of Microcosm favourites, including the Rutherford experiment, the cosmic ray display and the Thomson experiment. "We&...

    In 2015, the artists participated in a research residency at CERN and began to work with data captured by ATLAS, one of the four detectors at the Large Hadron Collider (LHC) that sits in a cavern 100 metres below ground near the main site of CERN, in Meyrin (Switzerland). For Art Basel, they created HALO, an installation that surrounds visitors with data collected by the ATLAS experiment at the LHC. HALO consists of a 10 m wide cylinder defined by vertical piano wires, within which a 4-m tall screen displays particle collisions. The data also triggers hammers that strike the vertical wires and set up vibrations to create a truly multisensory experience. More info: https://arts.cern/event/unveiling-halo-art-basel

  12. EFQPSK Versus CERN: A Comparative Study

    2001-01-01

    This report presents a comparative study on Enhanced Feher's Quadrature Phase Shift Keying (EFQPSK) and Constrained Envelope Root Nyquist (CERN) techniques. These two techniques have been developed in recent times to provide high spectral and power efficiencies under nonlinear amplifier environment. The purpose of this study is to gain insights into these techniques and to help system planners and designers with an appropriate set of guidelines for using these techniques. The comparative study presented in this report relies on effective simulation models and procedures. Therefore, a significant part of this report is devoted to understanding the mathematical and simulation models of the techniques and their set-up procedures. In particular, mathematical models of EFQPSK and CERN, effects of the sampling rate in discrete time signal representation, and modeling of nonlinear amplifiers and predistorters have been considered in detail. The results of this study show that both EFQPSK and CERN signals provide spectrally efficient communications compared to filtered conventional linear modulation techniques when a nonlinear power amplifier is used. However, there are important differences. The spectral efficiency of CERN signals, with a small amount of input backoff, is significantly better than that of EFQPSK signals if the nonlinear amplifier is an ideal clipper. However, to achieve such spectral efficiencies with a practical nonlinear amplifier, CERN processing requires a predistorter which effectively translates the amplifier's characteristics close to those of an ideal clipper. Thus, the spectral performance of CERN signals strongly depends on the predistorter. EFQPSK signals, on the other hand, do not need such predistorters since their spectra are almost unaffected by the nonlinear amplifier, Ibis report discusses several receiver structures for EFQPSK signals. It is observed that optimal receiver structures can be realized for both coded and uncoded EFQPSK

On Sunday, April 12, an avalanche buried four out of five skiers, taking part in a ski touring in the region of the Becs de Bosson in Valais (CH). The fifth skier, who had not been buried in the snow,  courageously managed to save two of the skiers, but Hervé Milcent, 49 years, federal ski instructor, and Mattieu Cattin, 33 years, were buried under two to three meters of snow, far down the avalanche slope, and did not survive, despite the fast arrival of the mountain rescue. In its 40 years of existence, the CERN Ski Club, one of the biggest in the Geneva area, has never been confronted with such a tragedy. The passing of Hervé and Matthieu has deeply shocked and saddened all volunteers of the Club as well as the entire alpine community.

    Early success with the CERN 28 GeV proton synchrotron (PS) prompted three questions about the future. Which areas of high energy particle physics would offer the best chance of progress, and with which accelerators? Which detectors would be needed? What experiments would be most likely to succeed? About 1963 it was suggested that the PS be extended with intersecting storage rings (ISR), and a 300 GeV SPS be built. By 1971 the ISR was ready for experiments, and the SPS proposal approved. At the present time the SPS programme comprises 28 experiments in the West Hall. (0 refs).

    Although raw physics data is produced at CERN, thanks to the GRID its analysis is performed in various institutes worldwide. In addition, workshops, conferences and meetings take place all over the world. The physicist community is decentralized, and CERN must continue to provide intellectual leadership. The LHC Physics Centre is the tool that will make this possible.   Until the early days of LEP, a large part of the scientific activity related to CERN’s experiments was strongly centered at the Laboratory. Few places had the infrastructure to host activities such as the working groups preparing the Yellow Reports, and the limited access to information in the pre-web era made CERN the natural place to learn what was happening in the field. “I remember the days when we, the theorists, would come to CERN just to read the most recent preprints, which were reaching CERN's Library before we could get them in our institutes”, says Michelangelo Mangano, a member of the Theo...

    2008-01-01

    Are you wondering about the intricacies of using videoconferencing and other collaborative tools at CERN? Our two new courses might just be the answer! In April 2008 the venerable VRVS service was shut down and replaced by EVO. EVO is a Java-based, cross-platform collaborative tool which allows you to hold meetings from your office or from a CERN video conference room. Because of ever-increasing usage of EVO at CERN, IT-UDS-AVC is organizing an introductory EVO course entitled "A hands-on overview of EVO", which will cover the basic usage of EVO (hardware recommendations; booking meetings; joining an EVO meeting from a CERN conference room/office/phone; moderating meetings). This course will be held as a hands-on session in the training centre, and mainly targets meeting conveners and users who want to join meetings from their office. We also organize a course entitled "Videoconferencing and collaborative tools at CERN", which is a general introduction to the videoconferenc...

    CERN Multimedia

    2015-01-01

    Bernard Hyams, a distinguished scientist who worked at CERN for 32 years, died on 15 May 2015 at the age of 90.     He started his career in Manchester, at Blackett’s laboratory, working on a magnetic spectrograph to measure the momentum of single cosmic ray particles (1950). Then, leading a group from Manchester University, he set up a cosmic ray experiment at the Pic du Midi Observatory in France. Having joined CERN in 1958, he performed one of the first experiments at the PS by demonstrating that in pion decay the muon spin behaves as expected. After studying vector meson decays into muon pairs, he spent several years working on precision pion measurements. When the ISR started operation in early 1971, it was realised that there was no experiment in place capable of looking for quarks, which was quite sobering, considering the ISR was constructed as a “discovery machine”. Bernard acted decisively, supporting a small and mostly young team of...

  17. New spam-detection engine for CERN mailboxes

    CERN Multimedia

    IT Department

    2008-01-01

    The flow of spam (unsolicited e-mail) targetting CERN mailboxes is constantly increasing: 96% of the 2.5 million mails received daily at CERN consist in successfully filtered spam, but spammers get smarter and detecting spam is becoming ever more difficult. In order to address this evolution, a new spam-detection software engine will progressively be deployed starting from 15 April 2008. It will not affect how CERN users currently deal with spam: the spam configuration page, the ‘CERN Spam’ folder and the Outlook ‘report spam’ button will continue to work exactly as before. Because spam detection is based on probabilities, some legitimate messages can sometimes be incorrectly detected as spam. We invite all users of CERN mailboxes to regularly check their ‘CERN spam’ folder for such messages. To prevent incorrect filtering of legitimate messages, it is possible to set up a whitelist (list of trusted e-mail addresses that bypass the spam filter) and adjust the spa...

    2011-01-01

    A rich harvest of important prizes has recently been awarded to CERN communication efforts. The list includes: the European Excellence Award 2010, the physics.org “people’s choice” award for the best children's website, and two prizes in the UK Recruitment Advertising Awards for 2011. Given the high expectations surrounding CERN's future physics results, there is little doubt that the old refrain “the best is yet to come” also applies to communication at CERN.   Marie Anne Bugnon and Antonella del Rosso, from the Communication Group, accept the 2010 European Excellence Award for LHC First Physics. In recent years, efforts to communicate as much and as well as possible have been stepped up at CERN – across all communities – and the fruits have come little by little. First of all, awards represent the recognition of the public, which, on different levels, has shown that it appreciates CERN’s efforts to...

  10. The ELENA project at CERN

    CERN Document Server

    Oelert, W

    2015-01-01

    CERN has a longstanding tradition of pursuing fundamental physics on extreme low and high energy scales. The present physics knowledge is successfully described by the Standard Model and the General Relativity. In the anti-matter regime many predictions of this established theory still remain experimentally unverified and one of the most fundamental open problems in physics concerns the question of asymmetry between particles: why is the observable and visible universe apparently composed almost entirely of matter and not of anti-matter? There is a huge interest in the very compelling scientiic case for anti-hydrogen and low energy anti-proton physics, here to name especially the Workshop on New Opportunities in the Physics Landscape at CERN which was convened in May 2009 by the CERN Directorate and culminated in the decision for the final approval of the construction of the Extra Low ENergy Antiproton (ELENA) ring by the Research Board in June 2011.

    The number of laptops stolen from or lost by CERN staff and users is not negligible. On average, four to five devices are reported lost or stolen to the CERN Fire Brigade every month.   The real number might be even higher as not everyone is aware that such thefts/losses should be reported in this way. Along with each laptop, private e-mails and personal documents, as well as MARS forms, contracts, NDAs, etc. are also lost. Fortunately, CERN has not lost any sensitive data so far (unlike other companies). In parallel with the approval by the Enlarged Directorate at its latest session of the development of a CERN-wide Data Protection Policy, the IT Department has prepared measures allowing you to protect the data on your laptop using full hard-disk encryption. While the word “encryption” might sounds complicated, the IT Department has fully automated the encryption process.

    Witowski, Sebastian

    2017-01-01

    The Large Hadron Collider at CERN is producing 600 million collisions every second. Only 1 in a million collisions is interesting. It requires a fast programming language to analyze and filter this amount of data. Is Python such a language? No, it’s not. Does it mean there is no place for Python in one of the largest scientific facilities in the world? Quite the contrary. The ease of use and a very low learning curve makes Python a perfect programming language for many physicists and other people without the computer science background. CERN does not only produce large amounts of data. The interesting bits of data have to be stored, analyzed, shared and published. Work of many scientists across various research facilities around the world has to be synchronized. This is the area where Python flourishes. And with CERN’s pursuit to create and use open source software, many interesting projects were born. To facilitate the analysis of data, ROOT framework [https://root.cern.ch/] was created.

    CERN Multimedia

    2014-01-01

    We would like to draw your attention to the CERN openlab IT in Healthcare Workshop (see here) that will take place at CERN on Tuesday 11 November.   CERN openlab is a unique public-private partnership between CERN and leading ICT companies. It was created in 2001 in support of the ambitious computing and data management goals set by the construction of the Large Hadron Collider (LHC) and detectors. Building on more than 10 years of ground-breaking work, CERN openlab continues to address the key topics in the CERN scientific and technical programme driven by the planned LHC upgrade activities spanning the next 20 years. The next phase of CERN openlab, Phase V, will start in January 2015 for three more years of joint technical collaborations. The scope of openlab is being expanded beyond High Energy Physics communities to understand how to address major computing and data analysis challenges in as diverse scientific disciplines as healthcare, radioastronomy, neurology or environmental research. ...

  11. Dynamic beam cleaning by a nonlinear resonance

    Energy Technology Data Exchange (ETDEWEB)

    Chao, A W; Month, M [Brookhaven National Lab., Upton, N.Y. (USA)

    1976-03-15

    The general framework for the dynamic cleaning of a stored proton beam by passing the beam through a nonlinear resonance is developed. The limitations and advantages of this technique are discussed. The method is contrasted with physical beam scraping, which is currently in use at the CERN ISR.

  12. Production of the charmonium states in the direct channel of pantip annihilation and description of a new experimental method. Exclusive reactions pantip#-> #e+e-

    International Nuclear Information System (INIS)

    Brom, J.M.

    1985-06-01

    The experiment R704 at the CERN Intersecting Storages Rings (ISR) utilised a completely new technique for charmonium spectroscopy, using a cooled antiprotons beam in collision with protons of a dense, molecular H 2 ''jet target''. ISR operations, jet target and experimental apparatus are described. Observation of the reaction pantip#-> #J/Ψ#-> #e + e - (193 evts for an integrated luminosity of 141 nb -1 ) and estimation of the J/Ψ mass using the beam parameters (3096.95±0.1±0.27 MeV) are used to test the method, the energy calibration and the reproductibility of the ISR. From these results, a very good precision of ± 300 KeV is expected in the later results on J PC ≠ 1 -- states. In addition, we give new upper limits for the magnetic form factor of the proton at high transfer [fr

  17. CERN as seen by its personnel

    CERN Multimedia

    2009-01-01

    How are the various players in research experiencing the run-up to the restart of the LHC? How do they feel their work is perceived outside CERN? After interviewing the inhabitants of Meyrin, Divonne-les-Bains and Geneva on the subject of the LHC and CERN, the Bulletin went to put its questions to the CERN personnel themselves. For some, working at CERN had always been a childhood dream. Today, as we approach the restart of the largest particle accelerator in the world, everybody is very enthusiastic about taking part in this adventure. In the words of a CMS physicist: "This is something that happens once in a scientist’s lifetime!" But what do the researchers consider to be the most important thing we do at CERN? It’s difficult to pin them down to any one specific thing, so this question gets the virtually unanimous general reply: "the advancement of knowledge". Many also mention the concrete spin-offs of technology transfer. However, nobody can anticipate what developments will arise in this field: wh...

The LPCC will shortly begin issuing a weekly bulletin of its own, distributed by e-mail. Members of the CERN physics community and subscribers to the CERN Bulletin will receive the ...

  19. CHANGE@CERN:Changes in Industrial Services

    CERN Document Server

    2002-01-01

    The changes envisaged in the Management's draft plan will focus the resources of the Laboratory on the LHC project and its completion. One of CERN's largest areas of spending is in Industrial Service Contracts, which currently amount to nearly 15% of the CERN budget. At present more than 2000 people have access to CERN through such contracts, although the nature of the contracts means that expenditure is not only on labour but also on materials. The revised cost to completion of the LHC has caused understandable concern that savings in Industrial Services will give rise to job losses at CERN, and rumours of '500 lay-offs' appeared in some newspaper reports. These reports were based on misunderstanding and speculation rather than the actual plan being prepared at CERN. The current proposal regarding expenditure on Industrial Services - which is supported by the findings of Task Force 3 - is to redirect about CHF170 M to the LHC, spread over the period 2003-2009. Crucially, the Management's plan envisages a r...

  20. CERN's vacuums honoured to the full

    CERN Multimedia

    2002-01-01

    CERN's Cristoforo Benvenuti is awarded one of the most prestigious prizes in the world of vacuum techniques     Because we constantly run into such individuals, we tend to forget that CERN has specialists with world reputations. It takes the international prizes they win to remind us of the fact. One such prize, the American Vacuum Society (AVS)'s Gaede-Langmuir Award for 2002, has gone to Cristoforo Benvenuti, Leader of the Surfaces and Materials Technologies Group in EST Division. The award, conferred once every two years, is one of the leading prizes in the vacuum field. By coincidence, its very first winner was Pierre Auger, one of CERN's founding fathers, back in 1978. Cristoforo Benvenuti, a senior physicist who joined CERN in 1966, has been singled out for his work on getter technologies. These technologies made their name at CERN with the coming of LEP, where they were used for pumping the machine. Getter is a material with the property of capturing gas molecules and thereby actin...

    2007-01-01

    CERN is the guest of honour at the 35th International Inventions Fair, which will take place from 18th to 22nd April at Palexpo, in Geneva. CERN has been chosen as the guest of honour for its ability to develop new technologies and translate them for the benefit of society. For the Fair, CERN has teamed up with ten companies that have made use of technologies and ideas from the Laboratory. The CERN stand at the exhibition will be dedicated to a presentation of the Laboratory and the LHC. Each of the technologies featured will be highlighted on the stand, along with the companies that have put them into more general use. This will allow visitors to trace the path from basic research to practical application from start to finish. One example is Medipix, a particle detection technology that has found applications in medical imaging. Visitors to the Fair will be able to see a Medipix detector in action on the CERN stand, and use it to view the particles emitted by everyday objects.

  2. CERN firemen share their expertise

    CERN Multimedia

    Maximilien Brice

    2002-01-01

    Firemen from local fire brigades have been coming to CERN to learn modern fire-fighting techniques. The CERN firemen have some unique training equipment for two particularly dangerous fire hazards, flashover and backdraft. Backdraft occurs when a fire smoulders for a long time within a confined space. The gases produced by the embers fail to burn owing to a lack of oxygen. When the door of the room is opened, for example, the resulting inflow of oxygen causes a deflagration that may prove fatal. This series of photos shows the use of special apparatus to simulate the spectacular backdraft phenomenon, so that firemen training at CERN learn to understand it.

    On 30 August CERN turned aside from its usual day-to-day preoccupations when Director-General Herwig Schopper played host to the Dalai Lama of Tibet and his entourage during the holy man's 1983 visit to Europe. In welcoming his visitor, Professor Schopper stressed the role of particle physics in helping to understand man's place in the cosmos, and how the Dalai Lama's interest would further the interrelation of science, philosophy and religion. The Dalai Lama visited the UA 1 experiment (rolled back into its 'garage' during the present fixed target operations at CERN) and the large installations for the neutrino experiments in the West Area of the SPS machine. There was an intriguing exchange of views with CERN theorists, who described how science has continually modified our view of the world around us
