    What is the Universe made of? Where did it come from, where is it going and why does it behave the way it does? These are some of the questions that CERN set out to address when a small number of pioneering scientists created Europe’s first scientific international organization. Founded in 1954, in the aftermath of the Second World War, CERN is not only a first-class centre for fundamental research but also a pioneering adventure in international collaboration.

    We summarize the physics motivations for future accelerators at CERN. We argue that (a) a luminosity upgrade for the LHC could provide good physics return for a relatively modest capital investment, (b) CLIC would provide excellent long-term perspectives within many speculative scenarios for physics beyond the Standard Model, (c) a Very Large Hadron Collider could provide the first opportunity to explore the energy range up to about 30 TeV, (d) a neutrino factory based on a muon storage ring would provide an exciting and complementary scientific programme and a muon collider could be an interesting later option.

    The accelerator control systems at CERN will be renovated and many electronics modules will be redesigned as the modules they will replace cannot be bought anymore or use obsolete components. The modules used in the control systems are diverse: analog and digital I/O, level converters and repeaters, serial links and timing modules. Overall around 120 modules are supported that are used in systems such as beam instrumentation, cryogenics and power converters. Only a small percentage of the currently used modules are commercially available, while most of them had been specifically designed at CERN. The new developments are based on VITA and PCI-SIG standards such as FMC (FPGA Mezzanine Card), PCI Express and VME64x using transition modules. As system-on-chip interconnect, the public domain Wishbone specification is used. For the renovation, it is considered imperative to have for each board access to the full hardware design and its firmware so that problems could quickly be resolved by CERN engineers or its ...

    Building 300 right in the middle of the CERN site houses a special "antique": the Laboratory's very first accelerator. After several years in the wilderness following its decommissioning in 1990, the Synchrocyclotron is set to take on a new lease of life in the near future, this time as a visitor attraction.   The Synchrocyclotron as it was in 1975; it will be restored to this configuration for public viewing. The Synchrocyclotron (SC) began operation in 1957, two years before the PS was commissioned. Running at an energy of 600 MeV and producing beams of protons, neutrons, muons and pions, it helped to further research in the nuclear physics field for no fewer than 33 years, providing beams for various decay experiments as well as the muon capture experiment (*). Since the SC was decommissioned in 1990, three of its four buildings (160, 161 and 301) have been converted into offices for members of the ALICE collaboration, but the shielded hall housing the machine it...

    The context of this internship is the CERN summer student program for the year 2015. As a member of the CERN summer school, I have been assigned, in addition to the classes I attended in the morning, a scientific project within the BE-ABP-HSC section. This work was done under the directions of Benoit Salvant and Nicolo Biancacci whom I thank greatly for their help, patience and teaching. The project consisted in observing the effects generated by the beam passing through various devices. We focused mainly on the electromagnetic waves generated by beams of particles travelling along two of the accelerator's devices: A wire scanner and the TDI (LHC injection beam stopper). These Simulations are of importance to estimate the effect of the beam onto the surrounding apparatus and ensuring both that the latter doesn't get damaged and that the beam doesn't lose too much energy. All the models and simulations were done using c CST STUDIO SUITE software developed by the c CST company.

  8. A great start for the whole CERN accelerator chain

    CERN Multimedia

    2016-01-01

    With physics data-taking under way this week at the LHC, I’d like to take a look at what’s been happening at the rest of the CERN accelerator chain.   The LHC tends to dominate the news from CERN for all kinds of reasons, beech martens included, but we should not forget that there is a unique chain of accelerators upstream of the LHC, tended to and operated by an incredible group of people. If our whole accelerator chain does not work perfectly, nor can the LHC, and in addition to forming the LHC’s injector chain, our upstream accelerators support their own experiments, bringing great diversity to the CERN research programme. The chain begins with the proton source and Linac2, which have been faithfully delivering beams since 1978. This year, Linac2 accelerated its first beams on 29 February. Beams were then passed on to the PS Booster and the veteran PS, the linchpin of the CERN accelerator complex and in operation since 1959. The final link in the chain before the ...

    2012-01-01

    The Compact LInear Collider (CLIC) study is dedicated to the design of an electron-positron (e- e+) linear accelerator, colliding particle beams at the energy of 3 TeV. The CLIC required luminosity can be reached with powerful particle beams (14 MW each) colliding with extremely small dimensions and high beam stability at the interaction point. The accelerated particle beams must have dimensions of 45 nm in the horizontal plane and 1 nm in the vertical plane. CLIC relies upon a novel two-beam acceleration concept in which the Radio Frequency (RF) power is extracted from a low energy but high-intensity particle beam, called Drive Beam (DB), and transferred to a parallel high energy accelerating particle beam, called Main Beam (MB). The extraction and transfer of the RF power is achieved by the Power Extraction and Transfer Structures (PETS) and the particle beam acceleration is achieved with high precision RF-Accelerating Structures (AS), operating at 11.9942 GHz with an accelerating gradient of 100 MV/m, whi...

  12. AWAKE: Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN

    CERN Document Server

    Gschwendtner, E

    2014-01-01

    Plasma wakefield acceleration is a promising alternative reaching accelerating fields a magnitude of up to 3 higher (GV/m) when compared to conventional RF acceleration. AWAKE, world’s first proton-driven plasma wakefield experiment, was launched at CERN to verify this concept. In this experiment proton bunches at 400 GeV/c will be extracted from the CERN SPS and sent to the plasma cell, where the proton beam drives the plasma wakefields and creates a large accelerating field. This large gradient of ~GV/m can be achieved by relying on the self-modulation instability (SMI) of the proton beam; when seeded by ionization through a short laser pulse, a train of micro-bunches with a period on the order of the plasma wavelength (~mm) develops, which can drive such a large amplitude wake from a long proton bunch (~12 cm). An electron beam will be injected into the plasma to probe the accelerating wakefield. The AWAKE experiment is being installed at CERN in the former CNGS facility, which must be modified to mat...

    The AWAKE collaboration prepares a proton driven plasma wakefield acceleration experiment using the SPS beam at CERN. A long proton bunch extracted from the SPS interacts with a high power laser and a 10 m long rubidium vapour plasma cell to create strong wakefields allowing sustained electron acceleration. The electron bunch to probe these wakefields is supplied by a 20 MeV electron accelerator. The electron accelerator consists of an RF-gun and a short booster structure. This electron source should provide beams with intensities between 0.1 and 1 nC, bunch lengths between 0.3 and 3 ps and an emittance of the order of 2 mm mrad. The wide range of parameters should cope with the uncertainties and future prospects of the planned experiments. The layout of the electron accelerator, its instrumentation and beam dynamics simulations are presented.

Impressive pictures of the accelerators and detectors are also shown. This is correct but clearly incomplete since there are other didactic possibilities to explore while talking about one of the most important scientific institutions in the world. The aim of this article is to introduce a few simple physical calculations about some magnetic phenomena that took place in old accelerators and will be present when the LHC (Large Hadron Collider) starts working in 2007.

    One of CERN's most daring and successful undertakings was the quest for the intermediate bosons, W and Z. In this paper, we describe the accelerator part of the venture which relied on a number of innovations: an extension of the budding method of stochastic cooling by many orders of magnitude; the construction of the Antiproton Accumulator, depending on several novel accelerator methods and technologies; major modifications to the 26 GeV PS Complex; and the radical conversion of the 300 GeV SPS, which just had started up as an accelerator, to a protonâ€"antiproton collider. The SPS Collider had to master the beamâ€"beam effect far beyond limits reached ever before and had to function in a tight symbiosis with the huge detectors UA1 and UA2.

    During the first 3 years of LHC operation, the priority for the SCADA (Supervisory Control And Data Acquisition) of vacuum controls was to attend to user requests, and to improve its ergonomics and efficiency: access & presentation of information simplified and normalized; coherent functionalities & menus across all accelerators; automatic scripts instead of fastidious manual actions; enhanced tools for data analysis and for maintenance interventions. Several decades of cumulative developments, based on heterogeneous technologies and architectures, have been asking for a homogenization effort. The first LHC Long Shutdown (LS1) provides the opportunity to further standardize the vacuum controls systems [1], around Siemens-S7 PLCs (Programmable Logic Controllers) and PVSS SCADA. Meanwhile, exchanges with other Groups at CERN and outside Institutes have been promoted: to follow the global update policy for software libraries; to discuss philosophies and development details; and to accomplish common pro...

    Saraiva, João Pedro de Carvalho; Carvalho, João

    The scope of this thesis consists in the radiological characterization of chilled water pipes used for air-conditioning and exposed to ionizing radiation in the PS accelerator, one of the CERN accelerators, for more than 40 years. Due to corrosion problems, the 1200 m of steel pipeline were removed from the PS tunnel during the long shutdowns between the years 2000 to 2004. The radiological characterization, that included the use of FLUKA Monte Carlo simulations and the JEREMY code, began in mid-2011 and revealed a radionuclide inventory with the presence of 55Fe as dominant radionuclide and 60Co as dominant gamma emitter. Due to operational reasons, only 5.5% of the pipeline were characterized for validation. In the course of this work it was found that the contribution of both aforementioned radionuclides corresponds to more than 90% of the total computed IRAS factor (Indice Radiologique d’Acceptation en Stokage). Two different methods were used for the characterization of the PS pipes, yielding two diffe...

    2013-01-01

    Several indicators have pointed to the presence of an Electron Cloud (EC) in some of the CERN accelerators, when operating with closely spaced bunched beams. In particular, spurious signals on the pick ups used for beam detection, pressure rise and beam instabilities were observed at the Proton Synchrotron (PS) during the last stage of preparation of the beams for the Large Hadron Collider (LHC), as well as at the Super Proton Synchrotron (SPS). Since the LHC has started operation in 2009, typical electron cloud phenomena have appeared also in this machine, when running with trains of closely packed bunches (i.e. with spacings below 150ns). Beside the above mentioned indicators, other typical signatures were seen in this machine (due to its operation mode and/or more refined detection possibilities), like heat load in the cold dipoles, bunch dependent emittance growth and degraded lifetime in store and bunch-by-bunch stable phase shift to compensate for the energy loss due to the electron cloud.

    2006-01-01

    The Large Hadron Collider (LHC) at CERN (The European Organisation for Nuclear Research) is one of the largest and most complicated machines envisaged to date. The LHC has been conceived and designed over the course of the last 25 years and represents the cutting edge of accelerator technology with a collision energy of 14TeV, having a stored beam energy over 100 times more powerful than the nearest competitor. Commissioning of the machine is already nderway and operation with beam is intended for Autumn 2007, with 7TeV operation expected in 2008. The LHC is set to answer some of the fundemental questions in theoretical physics, colliding particles with such high energy that the inner workings of the quantum world can be revealed. Colliding particles together at such high energy makes very high demands on machine operation and protection. The specified beam energy requires strong magnetic fields that are made in superconducting dipole magnets, these magnets are kept only around two degrees above absolute zero...

    We have designed, built and tested a crystal calorimeter in the context of CERN’s first beam line for schools competition. The results of the tests at CERN show that the light output of our calorimeter depends on the energy deposited by particles (electrons and muons) hitting the crystals. Our design can be reproduced by high schools around the world, as we have avoided the use of toxic chemicals.

    A new joint CERN-Fermilab summer school is proving more popular than the organizers ever imagined. Interest in the first CERN-Fermilab Hadron Collider Physics Summer School, to be held at Fermilab on 9-18 August, has proved far greater than anyone anticipated, with 300 applications for the planned 100 places. In response, the Organizing Committee, led by Fermilab's Jeffrey Appel and Bogdan Dobrescu, has had to increase the class size to nearly 150 participants. 'The success of this initiative, with an unexpectedly large number of applications, shows both the great anticipation that exists in the world for the start up of the LHC, and the need for greater educational support to enable the hundreds of young researchers to get ready for a full and prompt exploitation of the LHC data,' explains CERN's Michelangelo Mangano, who is a member of the International Advisory Committee (IAC) for the school. 'Fulfilling the expectations of the students will be a great challenge, which we are all eager to tackle.' Fabiol...

    2011-01-01

    There has been a proposal by Caldwell et al to use proton beams as drivers for high energy linear colliders. An experimental test with CERN’s proton beams is being studied. Such a test requires a transfer line for transporting the beam to the experiment, a focusing section for beam delivery into the plasma, the plasma cell and a downstream diagnostics and dump section. The work done at CERN towards the conceptual layout and design of such a test area is presented. A possible development of such a test area into a CERN test facility for high-gradient acceleration experiments is discussed.

  8. A Proton-Driven Plasma Wakefield Acceleration experiment at CERN

    CERN Multimedia

    The AWAKE Collaboration has been formed in order to demonstrate protondriven plasma wakefield acceleration for the first time. This technology could lead to future colliders of high energy but of a much reduced length compared to proposed linear accelerators. The SPS proton beam in the CNGS facility will be injected into a 10m plasma cell where the long proton bunches will be modulated into significantly shorter micro-bunches. These micro-bunches will then initiate a strong wakefield in the plasma with peak fields above 1 GV/m that will be harnessed to accelerate a bunch of electrons from about 20MeV to the GeV scale within a few meters. The experimental program is based on detailed numerical simulations of beam and plasma interactions. The main accelerator components, the experimental area and infrastructure required as well as the plasma cell and the diagnostic equipment are discussed in detail. First protons to the experiment are expected at the end of 2016 and this will be followed by an initial 3–4 yea...

    2002-01-01

    The last of our series on the Task Forces. PS accelerator 'We had a clear mandate, which we could approach in a logical way', explains Steve Myers, Head of SL Division and convenor of Task Force 5, 'To avoid duplication of effort in the accelerator sector through a restructuring that would lead to greater efficiency and flexibility and so release resources for the LHC.' The implementation of all their recommendations is already underway, albeit with different time scales. In 2001 the accelerator sector involved more than 900 staff members in three divisions (LHC, PS and SL) and one unit (AC), working in 141 sections within 34 groups. The first step for the Task Force was to identify major activities within the sector and to set up inter-divisional working groups to review these activities (16 in all), identifying the technologies and the numbers of staff associated with each activity. The working groups were also asked to propose ways of grouping the activities into a new more efficient organizational stru...

    2000-01-01

    ELFE at CERN is the study of a quasi continuous electron accelerator that accelerates an average current of about 0.1 mA to 25 GeV. A polarized electron beam is injected into either a racetrack microtron or into a first recirculating linear accelerator and accelerated to 800 MeV. The acceleration from there to 25 GeV is achieved in a second recirculating linear accelerator. The beam passes seven times through super-conducting RF cavities that were previously used in LEP2, and gains about 3.5 GeV on each pass. The hadronic physics and machine aspects have been studied by a joint NuPECC-CERN Study Group. This paper reports on the findings of the machine study. Several of the following topics will be covered: Beam dynamics in a recirculating linear accelerator with a super-conducting RF system, vacuum, construction in the North Area of the SPS, experimental areas, manpower, cost and construction schedule.

    Many particle accelerators operate with very high beam power and very high energy stored in particle beams as well as in magnet systems. In the future, the beam power in high intensity accelerators will further increase. The protection of the accelerator equipment from the consequences of uncontrolled release of the energy is essential. This was the motivation for organizing a first school on beam losses and accelerator protection (in general referred to as machine protection). During the school the methods and technologies to identify, mitigate, monitor and manage the technical risks associated with the operation of accelerators with high-power beams or subsystems with large stored energy were presented. At the completion of the school the participants should have been able to understand the physical phenomena that can damage machine subsystems or interrupt operations and to analyze an accelerator facility to produce a register of technical risks and the corresponding risk mitigation and management strategie...

    2010-01-01

    The construction of Linac4, the new 160 MeV CERN H- injector, has started with the goal of improving the LHC injection chain from 2015 with a new higher energy linac. The low energy front end of Linac4 is based on a 352 MHz, 3-m long Radiofrequency Quadrupole (RFQ) accelerator [1]. The RFQ accelerates the 70 mA, 45 keV H- beam from the RF source to the energy of 3 MeV. The fabrication of the RFQ has started at CERN in 2009 and is presently in progress, aiming at the completion of the full structure by early 2011. The RFQ consists of three modules, one meter each; the fabrication alternates machining phases and stress relief cycles, for copper stabilization. Two brazing steps are required: one to assemble the four parts composing a module, and a second one to install the stainless steel flanges. In order to monitor that the tight mechanical and alignment budget is not exceeded, metrology measurements at the CERN workshop and RF bead-pull measurements are performed during the fabrication process.

    A student from the Simon Langton Grammar School for Boys in Kent (UK) has developed an app that displays data recorded by Medipix chips. Created for Android-based devices, the app is a new way for students to visualize the natural radiation in their local area.   James Hurst shows off the Medipix chips at his school's stand at the UK's Royal Society Summer Science Exhibition. James Hurst, 17, developed the app in the framework of the CERN@school project that Becky Parker, a former participant in CERN’s High School Teachers (HST) programme, set up in 2008. “The app is able to display pre-recorded data in both graphic and numeric formats,” explains James. “I am already envisaging further developments, which might include producing the iOS version and eventually a live data-taking system.” CLEAR (Comprehensive Langton Evaluation and Analysis of Radiation), as it is named, will soon be available free from the Android Market toget...

    In a collaboration between CERN, PSI and Sincrotrone Trieste (ST), a multi- purpose X-band accelerating structure has been designed and fabricated, used for high gradients tests in the CLIC structure testing program and in the FEL projects of PSI and ST. The structure has 72 cells with a phase advance of 5 pi/6 and includes upstream and down-stream wakefield monitors to measure the beam alignment. The SLAC mode launcher design is used to feed it with RF power. Following the CERN fabrication procedures for high-gradient structure, diffusion bonding and brazing in hydrogen atmosphere is used to assemble the cells. After tuning, a vacuum bakeout is required before the feedthroughs for the wake field monitors are welded in as a last step. We describe the experiences gained in finishing the first two structures out of a series of four and present the results from the RF tuning and low level RF tests.

    Zaharieva, Z; Peryt, M

    2011-01-01

    The Controls Configuration Database (CCDB) and its interfaces have been developed over the last 25 years in order to become nowadays the basis for the Configuration Management of the Controls System for all accelerators at CERN. The CCDB contains data for all configuration items and their relationships, required for the correct functioning of the Controls System. The configuration items are quite heterogeneous, depicting different areas of the Controls System – ranging from 3000 Front-End Computers, 75 000 software devices allowing remote control of the accelerators, to valid states of the Accelerators Timing System. The article will describe the different areas of the CCDB, their interdependencies and the challenges to establish the data model for such a diverse configuration management database, serving a multitude of clients. The CCDB tracks the life of the configuration items by allowing their clear identification, triggering of change management processes as well as providing status accounting and aud...

  6. Development of an In-Situ Radiological Classification Technique for Material from CERN's Accelerator Facilities

    CERN Document Server

    AUTHOR|(CDS)2081300; Froeschl, Robert; Forkel-Wirth, Doris

    CERN, the European Organization for Nuclear Research, operates high energy accelerators for particle physics research. Because of beam losses and subsequent particle interactions, radioactivity can be induced in certain accelerator components. Material and waste taken out of the accelerators facilities as a result of maintenance repair and upgrade actions as well as in case of decommissioning needs to be radiologically classied for future handling. Depending on the level of residual activity, some of these components are candidates for clearance from regulatory control in Switzerland. The Swiss radiation protection ordinance sets as criteria for clearance of material and waste from regulatory control the compliance with radionuclide specic limits for surface contamination and for specic activity as well as an ambient dose equivalent rate criterion. For objects with a mass below 1 kg a radionuclide specic clearance limit for total activity has to be respected. This work is focused on the specic activity criter...

    The ISOLDE RIB-facility at CERN has today been producing a vast range of radioactive beams since more than 30 years. The low-energy beams of ISOLDE will be complemented by a post-accelerator, REX-ISOLDE, currently being assembled. In order to convert the pseudo-DC, singly-charged beam from the ISOLDE mass separators into a cooled and bunched beam at higher charge states a novel scheme of trapping, cooling and charge-state breeding has been devised, using a linear Penning trap and an Electron Beam Ion Source (EBIS). This allows for subsequent acceleration by a short, cost-effective LINAC consisting of an RFQ, an IH-structure and three seven-gap resonators, reaching 0.8 - 2.2 MeV/u. The installation of REX-ISOLDE is well underway and the first post-accelerated radioactive beams are expected to be obtained during late 2000.

  9. On the possibility of accelerating multiply charged ions in the CERN Synchrocyclotron

    CERN Document Server

    Giannini, R

    1975-01-01

    Some problems relating to the possibility of accelerating light ions in the CERN SC are studied. Deuteron capture conditions and the optimum radio-frequency versus time curve are calculated. Internal beam currents of some micro-amperes seem obtainable when using the calutron source as for protons. The same calculations were repeated for N/sup 5+/ taking into account the charge exchange process in the vacuum. A transmission of between 5 and 10% has been calculated, giving some 10/sup 10/ particles per second with a PIG source.

  10. The new low frequency accelerating systems for the CERN PS booster

    Krusche, A

    1998-01-01

    A set of four, ferrite-loaded, low-frequency RF cavities equipped with local RF feedback has been built and installed in the CERN PS Booster rings. Together with the modified existing RF systems they now serve for acceleration as well as RF gymnastics of protons and heavy ions up to the highest beam intensities. The systems specifications with a frequency range of about 0.6 to 1.8 MHz and a nomina l RF peak voltage of 8 kV satisfy specifically the requirements of acceleration on harmonic 1 of the future proton beam for the LHC. The system design has been guided by the request for safety margins for high beam intensity operation and ease of maintenance and repair. Some design aspects are presented as well as the performance achieved.

    2016-09-01

    The first cryomodule of the new HIE-ISOLDE rare isotope accelerator has recently been commissioned with beam at CERN, with the second cryomodule ready for installation. Each cryomodule contains five superconducting low-beta quarter wave cavities, produced with the technology of sputtering a thin niobium film onto the copper substrate (Nb /Cu ). This technology has several benefits compared to the bulk niobium solution, but also drawbacks among which the most relevant is the increase of surface resistance with accelerating field. Recent work has established the possible connection of this phenomenon to local defects in the Nb /Cu interface, which may lead to increased thermal impedance and thus local thermal runaway. We have analyzed the performance of the HIE-ISOLDE cavities series production, as well as of a few prototypes', in terms of this model, and found a strong correlation between the rf properties and one of the model characteristic quantities, namely the total surface having increased interface thermal impedance.

    The CERN PS accelerator complex has been progressively converted to full computer controls without interrupting its full-time operation (more than 6000 hours per year with on average not more than 1% of the total down-time due to controls). The application software amounts to 120 man-years and 450'000 instructions: it compares with other large software projects, also outside the accelerator world: e.g. Skylab's ground support software. This paper outlines the application software structure which takes into account technical requirements and constraints (resulting from the complexity of the process and its operation) and economical and managerial ones. It presents the engineering and management techniques used to promote implementation, testing and commissioning within budget, manpower and time constraints and concludes with experience gained.

    The world’s first proton driven plasma wakefield acceleration experiment (AWAKE) is presently being studied at CERN. The experimentwill use a high energy proton beam extracted from the SPS as driver. Two possible locations for installing the AWAKE facility were considered: the West Area and the CNGS beam line. The previous transfer line from the SPS to the West Area was completely dismantled in 2005 and would need to be fully re-designed and re-built. For this option, geometric constraints for radiation protection reasons would limit the maximum proton beam energy to 300 GeV. The existing CNGS line could be used by applying only minor changes to the lattice for the final focusing and the interface between the proton beam and the laser, required for plasma ionisation and bunch-modulation seeding. The beam line design studies performed for the two options are presented.

  19. Application software of the CERN PS accelerator controls system - analysis of its cost and resources

    1986-06-01

    The CERN PS accelerators have evolved into one of the world's most sophisticated high energy physics facility. The variety of beams and their high repetition rate means that a most sophisticated controls system is required. This reflects on the application software. At the time of the completion of the new control system, nearly 1000 programs, amounting to around 450 000 lines of code, have been developed at the cost of approximately 120 man-years. The span of this software ranges from real-time application programs to special purpose development and management tools. This paper documents the cost, resources and production of this software project. These are analyzed in terms of the structure of the application software. Rules-of-thumb are suggested for estimating the required effort at various phases of the project and to define the implementation strategy.

    The Accelerator complex at the European Organisation for Nuclear Research (CERN) is composed of many systems which are required to function in a valid state to ensure safe beam operation. One key component of machine protection, the Beam Interlock System (BIS), was designed to interface critical systems around the accelerator chain, provide fast and reliable transmission of beam dump requests and trigger beam extraction in case of malfunctioning of equipment systems or beam losses. Numerous upgrades of accelerator and controls components during the Long Shutdown 1 (LS1) are followed by subsequent software updates that need to be thoroughly validated before the restart of beam operation in 2015. In parallel, the ongoing deployments of the BIS hardware in the PS booster (PSB) and the future LINAC4 give rise to new requirements for the related controls and monitoring software due to their fast cycle times. This paper describes the current status and ongoing work as well as the long-term vision for the integratio...

    Podlech, H; Repnow, R; Schwalm, D

    2002-01-01

    The REX-ISOLDE experiment which is presently under construction at CERN is intended to investigate exotic, very neutron-rich, radioactive nuclei. A linear accelerator will deliver radioactive beams which are produced by the isotope separator ISOLDE, with energies between 0.85 and 2.2 MeV/u. The linac will consist of an RFQ accelerator, an interdigital H-structure (IH) and three 7-gap- resonators for variable final energy. The 7-gap-resonators are being operated at a frequency of f=101.28 MHz with a pulsed power of P=90 k W (duty cycle 1:10). After the fabrication of the power type resonators, high-power tests were performed in order to prove the design voltage of 1.74 MV at 90 kW rf power. These tests were carried out with a /sup 32/S beam and showed that the 7-gap-resonators exceed their design voltage; voltages between 1.77 and 1.88 MV were reached. In this paper the status of the 7-gap-resonator accelerator and the results of the high-power test are reported. (4 refs).

    This special section is devoted to the proceedings of the conference `Winter School on Strings, Supergravity and Gauge Theories', which took place at CERN, the European Centre for Nuclear Research, in Geneva, Switzerland 9-13 February 2009. This event is part of a yearly series of scientific schools, which represents a well established tradition. Previous events have been held at SISSA, in Trieste, Italy, in February 2005 and at CERN in January 2006, January 2007 and January 2008, and were funded by the European Mobility Research and Training Network `Constituents, Fundamental Forces and Symmetries of the Universe'. The next event will take place again at CERN, in January 2010. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of several general lectures of four hours each, whose notes are published in this special section, and six working group discussion sessions, focused on specific topics of the network research program. It was well attended by over 200 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress, and to the open problems, in string theory. One of the most active areas in string theory in recent years has been the AdS/CFT or gauge/gravity correspondence, which proposes the complete equivalence of string theory on (asymptotically) anti de Sitter spacetimes with certain quantum (gauge) field theories. The duality has recently been applied to understanding the hydrodynamical properties of a hot plasma in gauge theories (like the quark-gluon plasma created in heavy ion collisions at the RHIC experiment at Brookhaven, and soon at the LHC at CERN) in terms of a dual gravitational AdS theory in the presence of a black hole. These developments were reviewed in the lecture notes by M Rangamani. In addition, the AdS/CFT duality has been proposed as a tool to study interesting physical properties in other

    Mauro, Egidio; Silari, Marco

    2009-01-01

    CERN is presently designing a new chain of accelerators to replace the present Proton Synchrotron (PS) complex: a 160 MeV room-temperature H$^-$ linac (Linac4) to replace the present 50 MeV proton linac injector, a 3.5 GeV Superconducting Proton Linac (SPL) to replace the 1.4 GeV PS booster (PSB) and a 50 GeV synchrotron (named PS2) to replace the 26 GeV PS. Linac4 has been funded and the civil engineering work started in October 2008, whilst the SPL is in an advanced stage of design. Beyond injecting into the future 50 GeV PS, the ultimate goal of the SPL is to generate a 4 MW beam for the production of intense neutrino beams. The radiation protection design is driven by the latter requirement. This thesis summarizes the radiation protection studies conducted for Linac4. FLUKA Monte Carlo simulations, complemented by analytical estimates, were performed 1) to evaluate the propagation of neutrons through the waveguide, ventilation and cable ducts placed along the accelerator, 2) to estimate the radiological i...

    The High Intensity and Energy ISOLDE (HIE-ISOLDE) project is a major upgrade of the existing ISOLDE and REX-ISOLDE facilities at CERN. The most significant improvement will come from replacing the existing REX accelerating structure by a superconducting linear accelerator (SC linac) composed ultimately of six cryo-modules installed in series, each containing superconducting RF cavities and solenoids operated at 4.5 K. In order to provide the cooling capacity at all temperature levels between 300 K and 4.5 K for the six cryo-modules, an existing helium refrigerator, manufactured in 1986 and previously used to cool the ALEPH magnet during LEP operation from 1989 to 2000, has been refurbished, reinstalled and recommissioned in a dedicated building located next to the HIE-ISOLDE experimental hall.

    For the selection of polymer-based materials to be used in radiation environments, radiation tests have been performed at the European Organization for Particle Physics Research (CERN) for several decades. According to the recommendations of the IEC Standard 544, mechanical tests are carried out, and the radiation degradation is measured after accelerated irradiations. It is well known that during long-term exposures, oxygen and moisture are allowed to diffuse in the materials and hence to induce more severe degradation; this phenomenon is known as the `dose-rate effect'. During machine shut-downs, samples of rigid and flexible polymeric insulators (magnet-coil resins and cable insulations) have been taken out and tested after several years of exposure in the Super Proton Synchrotron (SPS) and in the Large Electron-Position Collider (LEP). The mechanical test results are compared to the ones after the accelerated qualification tests, and to the ones of a study conducted in 1991 to estimate the lifetime of cables in the radiation environment of LEP 200. They confirm that thermoplastics are more sensitive to long-term irradiations than the thermosetting resins and the composites, but that the dose-rate effect cannot be neglected in the latter.

  12. Conference: ActiWiz – Optimizing material selection at CERN's accelerators from the radiological point of view

    CERN Multimedia

    2012-01-01

    by Dr. Helmut Vincke (CERN), Chris Theis (CERN). Tuesday, October 30, 2012 from 15:00 to 16:30 at CERN ( 864-1-D02 - BE Auditorium Prévessin ) Description: The operation of a high-energy accelerator inevitably triggers the activation of equipment, which poses a safety hazard. Consequently access and handling constraints have to be imposed to ensure optimized working conditions. One of the key parameters determining the level of radioactivity is the material composition. Considering the radiological impact in addition to the engineering requirements during the selection of material clearly results in a safety benefit as well as a more efficient accelerator operation due to less stringent access and handling constraints. Another aspect is the minimization of future radioactive waste, which constitutes an important part of CERN’s commitment to limit its environmental impact by applying best practices. The ActiWiz software developed at CERN provides an easy to use method to optimize the m...

    Roderick, C; Kruk, G

    2014-01-01

    During the 10 years since it's first operational use, the scope and scale of the CERN Accelerator Logging Service (LS) has evolved significantly: from an LHC specific service expected to store 1TB / year; to a CERN-wide service spanning the complete accelerator complex (including related sub-systems and experiments) currently storing more than 50 TB / year on-line for some 1 million signals. Despite the massive increase over initial expectations the LS remains reliable, and highly usable - this can be attested to by the 5 million daily / average number of data extraction requests, from close to 1000 users. Although a highly successful service, demands on the LS are expected to increase significantly as CERN prepares LHC for running at top energy, which is likely to result in at least doubling current data volumes. Furthermore, focus is now shifting firmly towards a need to perform complex analysis on logged data, which in-turn presents new challenges. This paper reflects on 10 years as an operational service,...

    The superconducting Large Hadron Collider (LHC) under construction at the European Organisation for Nuclear Research (CERN) is an accelerator unprecedented in terms of beam energy, particle production rate and also in the potential of self-destruction. Its operation requires a large variety of instrumentation, not only for the control of the beams, but also for the protection of the complex hardware systems. The Beam Loss Monitoring (BLM) system has to prevent the superconducting magnets from becoming normal conducting and protect the machine components against damages making it one of the most critical elements for the protection of the LHC. For its operation, the system requires 3600 detectors to be placed at various locations around the 27 km ring. The measurement system is sub-divided to the tunnel electronics, which are responsible for acquiring, digitising and transmitting the data, and the surface electronics, which receive the data via 2 km optical data links, process, analyze, store and issue warning...

    1986-06-01

    The CERN PS accelerators have evolved into one of the world's most sophisticated high energy physics facility. The variety of beams and their high repetition rate means that a most sophisticated controls system is required. This reflects on the application software. At the time of the completion of the new control system, nearly 1000 programs, amounting to around 450 000 lines of code, have been developed at the cost of approximately 120 man-years. The span of this software ranges from real-time application programs to special purpose development and management tools. This paper documents the cost, resources and production of this software project. These are analyzed in terms of the structure of the application software. Rules-of-thumb are suggested for estimating the required effort at various phases of the project and to define the implementation strategy.

  17. Facing new safety-challenges in a large particle accelerator experiment at CERN

    CERN Document Server

    Schmidt, Reiner

    1999-01-01

    An upgraded safety concept for CMS has been adapted to the size of the project and its organisational challenges under today's budgetary constraints, as well as to the increasing levels of risk. Strong magnetic fields and high radiation levels, including neutrons, pose additional hazards to materials, to operators, to maintenance and to ultimate deposit of activated materials. CMS also fits the insurer's risk-description for modern facilities, i.e. characterised by "higher energy density, more combustible materials and unattended operation". The regulatory environment, consisting essentially of CERN's autonomous regulations as well as of those of its host countries, also need to be satisfied with much attention. To face this challenge, seven distinct safety management tools have been identified, which are described in some detail, namely clear safety objectives, documented safety requirements, open items list, safety ( and design)reviews, safety risk analysis, enforcement of compliance and quality management....

  19. Natural air convection for cooling of particle accelerator electromagnets: case studies at CERN

    CERN Document Server

    Moreira, Mariana

    Cooling by natural convection is investigated on two air-cooled corrector magnets at CERN. The heat transfer coefficient (HTC) for each magnet is estimated analytically using established empirical correlations for certain geometries. The HTC is also estimated numerically with three-dimensional steady-state finite element simulations. Air convection around the respective coils as well as heat conduction inside the coils are modelled. Different formulas for the HTC are tested in the post-processing of the simulation results. The HTC for each magnet is then determined experimentally by measuring surface temperatures on the coils through time at constant currents. A method to extract the HTC from these temperature curves is developed, in which the curves are fitted to a function that is derived from a thermodynamical analysis of the heating process. Some plausible ranges for the HTC for each magnet for different currents are obtained. The results of the different estimation methods are compared with the experimen...

    2015-01-01

    This school is a continuation of the series of schools that began nine years ago: Japan 2006, Italy 2007, United States 2008, China 2009, Switzerland 2010, United States 2011, India 2012 and Turkey 2013. Based on needs from the accelerator community, the Linear Collider Collaboration (LCC) and ICFA Beam Dynamics Panel are organising the Ninth International Accelerator School for Linear Colliders. The school will present instruction in TeV-scale linear colliders including the ILC, CLIC and other advanced accelerators. An important change of this year’s school from previous LC schools is that it will also include the free electron laser (FEL), a natural extension for applications of the ILC/CLIC technology. The school is offered to graduate students, postdoctoral fellows and junior researchers from around the world. We welcome applications from physicists who are considering changing to a career in accelerator physics and technology. This school adopts an in depth approach. A selective course on the FEL has b...

    After 3 years of operation, the LHC entered its first Long Shutdown period (LS1), in February 2013 [1]. Major consolidation and maintenance works are being performed across the whole CERN’s Accelerator chain, in order to prepare the LHC to restart at higher energy, in 2015. The injector chain shall resume earlier, in mid-14. We report about the on-going vacuum-controls projects. Some of them concern the renovation of the controls of certain machines; others are associated with the consolidations of the vacuum systems of LHC and its injectors; and a few are completely new installations. ue to the wide age-span of the existing vacuum installations, there is a mix of design philosophies and of control-equipment generations. The renovations and the novel projects offer an opportunity to improve the uniformity and efficiency of vacuum controls by: reducing the number of equipment versions with similar functionality; identifying, naming, labelling, and documenting all pieces of equipment; homogenizing the contr...

    Only a handful of universities in the US offer any formal training in accelerator science. The United States Particle Accelerator School (USPAS) is National Graduate Educational Program that has developed a highly successful educational paradigm that, over the past twenty-years, has granted more university credit in accelerator / beam science and technology than any university in the world. Sessions are held twice annually, hosted by major US research universities that approve course credit, certify the USPAS faculty, and grant course credit. The USPAS paradigm is readily extensible to other rapidly developing, crossdisciplinary research areas such as high energy density physics.

    Full Text Available The distribution of the school work into a serial sequence of interlocked years install negative conditions to learning, and everyday living, for students with intellectual ability and level of achievement higher than their peer group. Acceleration is a way to advance these students through school curriculum is less time than required, without submitting them to the minimum age limits established by school systems. The big conundrum is that although it is one of the most studied themes is both, Education and Gifted Education, the results of such research do not have an impact in the educational practice, still marked by strong resistance within the school milieu. This article discuss acceleration as a measure to develop academic talent, also the expression of intelligence as an ability domain most and perhaps better studied, in the area of giftedness and talent.

    CERN in Switzerland is presently building a new particle accelerator labeled as the LHC. This 27 km accelerator will, for the first time at such a large scale, operate at cryogenic temperatures with superconducting magnets and radio-frequency cavities. For that purpose, Air Liquide has designed, constructed and started up two custom designed refrigerators. The cryogenic power of each of these refrigerators is equivalent to 18 kW at 4.5 K. In order to produce the cryogenic power requested by the LHC accelerator at the different temperature levels with a very high efficiency, a custom design thermodynamic cycle has been chosen. This cycle, the major components of the refrigerators and the results obtained during the reception tests of the refrigerators are presented in this paper.

This event was organized in the framework of the European Mobility Research and Training Network entitled 'Constituents, Fundamental Forces and Symmetries of the Universe'. It is part of a yearly series of scientific schools, which represents what is by now a well established tradition. The previous conferences have been held at SISSA, in Trieste, Italy, in February 2005 and at CERN in January 2006. The next will again take place at CERN, in January 2008. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of several general lectures of four hours each, the notes of which are published in the present proceedings, and seven working group discussion sessions, focused on specific topics of the network research program. It was attended by approximatively 250 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress, and to the open problems, in string theory. String theory is a compelling candidate for a theory of all interactions. A basic challenge in this field is therefore to explore the connection of string theory models and the laws of physics in different realms, like high-energy particle physics, early cosmology, or physics of strongly coupled gauge theories. Concerning the exploration of string theory compactifications leading to realistic models of particle physics, one of the main obstacles in this direction is the proper understanding of supersymmetry breaking. The lecture notes by Nathan Seiberg review the realization of spontaneous breaking of supersymmetry in field theory, including recent developments via the use of meta-stable long-lived vacua. It is

  16. Design Study and Optimization of Irradiation Facilities for Detector and Accelerator Equipment Testing in the SPS North Area at CERN

    CERN Document Server

    Biskup, Bartolomej; Stekl, Ivan

    Due to increasing performance of LHC during the last years, the strong need of new detector and electronic equipment test areas at CERN appeared from user communities. This thesis reports on two test facilities: GIF++ and H4IRRAD. GIF++, an upgrade of GIF facility, is a combined high-intensity gamma and particle beam irradiation facility for testing detectors for LHC. It combines a high-rate 137Cs source, providing photons with energy of 662 keV, together with the high-energy secondary particle beam from SPS. H4IRRAD is a new mixed-field irradiation area, designed for testing LHC electronic equipment for radiation damage effects. In particular, large volume assemblies such as full electronic racks of high current power converters can be tested. The area uses alternatively an attenuated primary 400 GeV/c proton beam from SPS, or a secondary, mainly proton, beam of 280 GeV/c directed towards a copper target. Different shielding layers are used to reproduce a radiation field similar to the LHC “tunnel” and �...

This event was organized in the framework of the European Mobility Research and Training Network entitled 'Constituents, Fundamental Forces and Symmetries of the Universe'. It is part of a yearly series of scientific schools, which represents what is by now a well established tradition. The previous ones have been held at SISSA, in Trieste, Italy, in February 2005 and at CERN in January 2006. The next one will again take place at CERN, in February 2009. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of several general lectures of four hours each, whose notes are published in the present proceedings, and five working group discussion sessions, focused on specific topics of the network research program. It was attended by approximatively 250 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress, and to the open problems, in string theory. One of the most active areas in string theory in recent years is the AdS/CFT or gauge/gravity correspondence, which proposes the complete equivalence of string theory on (asymptotically) anti-de Sitter spacetimes with gauge theories. The duality relates the weak coupling regime of one system to the strongly coupled regime of the other, and is therefore very non-trivial to test beyond the supersymmetry-protected BPS sector. One of the key ideas to quantitatively match several quantities on both sides is the use of integrability, both in the gauge theory and the string side. The lecture notes by Nick Dorey provide a pedagogical introduction to the fascinating topic of integrability in AdS/CFT. On the string theory side, progress has

  7. Wall-Current-Monitor based Ghost and Satellite Bunch Detection in the CERN PS and the LHC Accelerators

    Steinhagen, R J; Belleman, J; Bohl, T; Damerau, H

    2012-01-01

    While most LHC detectors and instrumentation systems are optimised for a nominal bunch spacing of 25 ns, the LHC RF cavities themselves operate at the 10th harmonic of the maximum bunch frequency. Due to the beam production scheme and transfers in the injector chain, part of the nominally ‘empty’ RF buckets may contain particles, referred to as ghost or satellite bunches. These populations must be accurately quantified for high-precision experiments, luminosity calibration and control of parasitic particle encounters at the four LHC interaction points. This contribution summarises the wall-current-monitor based ghost and satellite bunch measurements in CERN’s PS and LHC accelerators. Instrumentation set-up, post-processing and achieved performance are discussed.

    2014-01-01

    What is industrial radiography? It is a non-destructive method with a wide variety of applications, such as inspecting the quality of a weld. It uses high-energy radioactive sources or an X-ray generator.   Is this inspection technique used at CERN? Yes, it is widely used at CERN by the EN-MME Group, which outsources the work to one or more companies, depending on the workload. Is it possible to carry out radiography anywhere at CERN? Yes, it is possible to carry out radiography in any building/accelerator/experiment area at CERN (including in areas which are not normally subject to radiological hazards). When is radiography carried out? It normally takes place outside of working hours (7 p.m. to 6 a.m.). How will I know if radiography is taking place in my building? If this activity is planned in a CERN building, notices will be affixed to all of its main entrance doors at least 24 hours in advance. What are the risks? There is a risk of exposure to very high levels of radiation, dep...

    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.

Today our guest is Mike Lamont, who is in charge of the Operations Group for the accelerator beams. This weekend, protons were injected into the LHC for the first time since September 2008. But before we talk about that, let's go back a few weeks and look at the previous stage, which involved testing the transfer lines of the injection tunnels TI2/TI8. Our video team was there to film this operation.

  7. CERN: an aerial view

    CERN Multimedia

    2004-01-01

    On 30th January, when CERN still resembled a winter wonderland, a helicopter with a photographer on board took off on an aerial tour. One sunny morning at the end of January, when the area was waking up to an overnight snowfall, a helicopter took off from the Meyrin site with a CERN photographer on board. CERN has been the subject of aerial photographs ever since its creation. Although its appearance has changed over the years, the Laboratory has aged well. The aerial photographs taken during its fifty-year history bear witness to its expansion, showing how a handful of buildings and a first accelerator have blossomed into an entire machine complex. Let's take to the skies and have a look at some of the photos taken on this crisp January morning: a sight for sore eyes! In the foreground, Building 40 on the Meyrin site is recognisable from its magnet shape.On the right of the Route de Meyrin (crossing the photo diagonally), next to Point 1, the work on the Globe of Innovation, which got underway at the beg...

    This animation shows how the Large Hadron Collider (LHC) works. The film begins with an aerial view of CERN near Geneva, with outlines of the accelerator complex, including the underground Large Hadron Collider (LHC), 27-km in circumference. The positions of the four largest LHC experiments, ALICE, ATLAS, CMS and LHCb are revealed before we see protons travelling around the LHC ring. The proton source is a simple bottle of hydrogen gas. An electric field is used to strip hydrogen atoms of their electrons to yield protons. Linac 2, the first accelerator in the chain, accelerates the protons to the energy of 50 MeV. The beam is then injected into the Proton Synchrotron Booster (PSB), which accelerates the protons to 1.4 GeV, followed by the Proton Synchrotron (PS), which pushes the beam to 25 GeV. Protons are then sent to the Super Proton Synchrotron (SPS) where they are accelerated to 450 GeV. The protons are finally transferred to the two beam pipes of the LHC. The beam in one pipe circulates clockwise while ...

    2006-01-01

    The Technical Infrastructure Monitoring system (TIM) is used to monitor and control CERN's technical services from the CERN Control Centre (CCC). The system's primary function is to provide CCC operators with reliable real-time information about the state of the laboratory's extensive and widely distributed technical infrastructure. TIM is also used to monitor all general services required for the operation of CERN's accelerator complex and the experiments. A flexible data acquisition mechanism allows TIM to interface with a wide range of technically diverse installations, using industry standard protocols wherever possible and custom designed solutions where needed. The complexity of the data processing logic, including persistence, logging, alarm handling, command execution and the evaluation of datadriven business rules is encapsulated in the system's business layer. Users benefit from a suite of advanced graphical applications adapted to operations (synoptic views, alarm consoles, data analysis tools etc....

    Launched in 2014, the Beamline for Schools (BL4S) competition allows high-school students between 16 and 18 years old to run a real experiment at CERN’s PS accelerator (see here). For two years, students and schools worldwide have risen to the challenge and taken part enthusiastically in the competition. To ensure that it runs smoothly and enjoyably, over 100 CERN people work behind the scenes. The Bulletin lifts the curtain.   Student teams from Greece and the Netherlands – the winners of CERN’s first Beamline for schools competition – came to CERN to work on their experiments using a test beam. Turning young high-school students into real physicists who use a high-energy beam, set up an experiment and deal with data acquisition and analysis, is no game. For the people at CERN, the first step is to select the best proposals from those received from schools worldwide. “In 2015, over 40 scientists helped us select the best proposa...

    CERN's fascinating history, from the period preceding its creation right up to the present day, has inspired many people to take up pen and paper over the years. Recently, Marie Mazzone, a 19-year old student at Geneva's Collège Sismondi, chose it as the subject for her "travail de maturité", which she presented in the form of a comic book.   Cover of "the Accelerator of Peace" comic book by Marie Mazonne. In her comic book, which she entitled "L’accélérateur de paix" (the Accelerator of Peace, see the full PDF), Marie traces CERN's history back to its creation, explaining how the needs of post-war Europe led to the construction of an international scientific laboratory. Marie's four grandparents are all former CERN employees, so the Organization has been part of her life ever since she was small. "I'd always been familiar with the word CERN," she tells us. "But I...

    To better prepare students for college-level math and the demands of the labor market, school systems have tried to increase the rigor of students’ math coursework. The failure of universal “Algebra for All” models has led recently to more targeted approaches. We study one such approach in Wake County, North Carolina, which began using prior test scores to assign middle school students to an accelerated math track culminating in eighth grade algebra. The policy has reduced the role that incom...

    In the effort to examine the factors that impact the use of ICT by teachers, research has up until now neglected the acceleration of ICT developments as a factor that affects the successful integration of ICT in education. The technological acceleration in general has triggered significant changes at the social level, such as the acceleration of social change and the acceleration of the pace of life. This is why the study of the acceleration of ICT provides for a good theoretical framework to...

    2001-01-01

    For the second year running, a group of Belgian high school students spent three days at CERN discovering that physics is far from boring and can even be fun. The students were obliged to revise their stereotyped image of the average physicist - the strange person with thick glasses who seems to have landed from another planet - and replace it with a young and enthusiastic person not too different from themselves. The 45 Belgian students gave up a part of their holidays to learn all about accelerators, detectors, and the wonders of particle physics. They were not disappointed, as they took home great memories, lots of documentation, and - who knows - maybe even dreams of a life in physics. The students came from all over the Flemish part of Belgium, united by a common wish - to see CERN from the inside. They were guided through the Laboratory by Belgian physicists involved with the Laboratory. Their visit started with an introduction to particle physics and CERN by Walter Van Doninck from the Vrije Universi...

    CERN SSM (Safety System Monitoring) [1] is a system for monitoring state-of-health of the various access and safety systems of the CERN site and accelerator infrastructure. The emphasis of SSM is on the needs of maintenance and system operation with the aim of providing an independent and reliable verification path of the basic operational parameters of each system. Included are all network-connected devices, such as PLCs, servers, panel displays, operator posts, etc. The basic monitoring engine of SSM is a freely available system-monitoring framework Zabbix [2], on top of which a simplified traffic-light-type web-interface has been built. The web-interface of SSM is designed to be ultra-light to facilitate access from handheld devices over slow connections. The underlying Zabbix system offers history and notification mechanisms typical of advanced monitoring systems.

    The Large Hadron Collider (LHC) from CERN is a 14 TeV proton-proton collider that is at the cutting edge of technology, and is a heartening sign of both the public's support for basic science in Europe and beyond, and the determination of European countries to stay at the forefront of particle physics. Realization of this project started some 50 years ago. Now for the next 50 years, particle phycists not only at CERN are planning a new generation of experiments that will push the high-energy boundary back even further. At CERN, a high-energy electron-positron linear collider, such as the 3-5 TeV Compact Linear Collider (CLIC) project is being considered. At Fermilab, focus is on a Very Large Hadron Collider (VLHC) that would take physicists into the 200 TeV region. These two possibilities could be among the long-term goals of the global accelerator network, which would keep the world's particle physicists busy until 2050.

    New webpages answer common questions about CERN and the environment.   One of the new public webpages dedicated to CERN and the environment. Do your neighbours ever ask you about CERN’s environmental impact? And about radiation in particular? If so, the answers to those questions can now be found online on a new set of public webpages dedicated to CERN and the environment. These pages, put together by the Occupational Health, Safety and Environmental Protection (HSE) unit and the groups responsible for CERN's site maintenance, contain a wealth of information on topics linked to the environment, such as biodiversity at CERN, waste management, ionising radiation, and water and electricity consumption. “CERN forms part of the local landscape, with its numerous sites and scientific activities. It’s understandable that people living nearby have questions about the impact of these activities and it’s important that we respond with complete transp...

    Aren’t we innovative and creative people? Building complex accelerators and doing sophisticated physics analysis is not easy and requires a lot of excellent brains. Some items of hardware are pure works of art, worthy of a place in an art museum. Some software takes advantage of all the finesse of computer science to optimize every last bit of computing power. So, yes. We are. Innovation and creativity are our middle names.   But I wonder why these splendid characteristics are lost when dealing with passwords? Recent computer security scans have found a series of unprotected passwords and, I hope you agree, “Operator1”, “SamFox” or “Admin123” do not reflect our innovative nature (and might even be taken as an insult).

  17. An accelerator worth fighting for

    1996-01-01

    Financial pressures from member states have upset the calculations of the European Laboratory for Particle Physics's (CERN) major accelerator, the Large Hadron Collider (LHC). Despite preference for domestic high energy programs, CERN members accord high priority to LHC physics. Converting to a global facility can help spread the high annual cost of subscription. But given the political realities, a revision of the LHC project appears more feasible. CERN's management needs to deploy its skills to overcome the financial obstacles to the facility.

    1995-01-01

    The plasma produced when a powerful laser pulse is focused onto a target surface in vacuum can provide a copious source of highly charged ions. Ions can then be extracted from the plasma to form a high current, short pulse length ion beam. Experimental laser ion sources have been the subject of investigation in medical physics and particle accelerator applications; a laser ion source is an option for the injection system of heavy ions for the Large Hadron Collider at CERN where a high intensity lead ion beam is required. This paper describes work carried out at CERN to develop a CO2 laser ion source.

    2011-01-01

    As the first step of a long-term programme aiming at an increase in the LHC luminosity, CERN is building a new 160 MeV H¯ linear accelerator, Linac4, to replace the ageing 50 MeV Linac2 as injector to the PS Booster (PSB). Linac4 is an 86-m long normal-conducting linac made of an H¯ source, a Radio Frequency Quadrupole (RFQ), a chopping line and a sequence of three accelerating structures: a Drift-Tube Linac (DTL), a Cell-Coupled DTL (CCDTL) and a Pi-Mode Structure (PIMS). The civil engineering has been recently completed, and construction of the main accelerator components has started with the support of a network of international collaborations. The low-energy section up to 3 MeV including a 3-m long 352 MHz RFQ entirely built at CERN is in the final construction phase and is being installed on a dedicated test stand. The present schedule foresees beam commissioning of the accelerator in the new tunnel in 2013/14; the moment of connection of the new linac to the CERN accelerator chain will depend on the L...

    In this work we analyse the biggest particle accelerator in the world: the LHC (Large Hadron Collider). The ring shaped tunnel is 27 km long and it is buried over 110 meters underground, straddling the border betwen France and Switzerland at the CERN laboratory near Geneva. Its mission is to recreate the conditions that existed shortly after the Big-Bang and to look for the hypothesised Higgs particle. The LHC will accelerate protons near the speed of the light and collide them head on at an energy of to 14 TeV (1 TeV = 10(12) eV). Keeping such high energy in the proton beams requires enormous magnetic fields which are generated by superconducting electromagnets chilled to less than two degrees above absolute zero. It is expected that LHC will be inaugurated in summer 2007.

    CERN Document Server

    AUTHOR|(CDS)2082069; Macián-Juan, Rafael

    Radiation protection calibration facilities are essential to ensure the correct operation of radiation protection instrumentation. Calibrations are performed in specific radiation fields according to the type of instrument to be calibrated: neutrons, photons, X-rays, beta and alpha particles. Some of the instruments are also tested in mixed radiation fields as often encountered close to high-energy particle accelerators. Moreover, calibration facilities are of great importance to evaluate the performance of prototype detectors; testing and measuring the response of a prototype detector to well-known and -characterized radiation fields contributes to improving and optimizing its design and capabilities. The CERN Radiation Protection group is in charge of performing the regular calibrations of all CERN radiation protection devices; these include operational and passive dosimeters, neutron and photon survey-meters, and fixed radiation detectors to monitor the ambient dose equivalent, H*(10), inside CERN accelera...

    2016-01-01

    Operation with closely spaced bunched beams causes the build-up of an Electron Cloud (EC) in both the LHC and the two last synchrotrons of its injector chain (PS and SPS). Pressure rise and beam instabilities are observed at the PS during the last stage of preparation of the LHC beams. The SPS was affected by coherent and incoherent emittance growth along the LHC bunch train over many years, before scrubbing has finally suppressed the EC in a large fraction of the machine. When the LHC started regular operation with 50 ns beams in 2011, EC phenomena appeared in the arcs during the early phases, and in the interaction regions with two beams all along the run. Operation with 25 ns beams (late 2012 and 2015), which is nominal for LHC, has been hampered by EC induced high heat load in the cold arcs, bunch dependent emittance growth and degraded beam lifetime. Dedicated and parasitic machine scrubbing is presently the weapon used at the LHC to combat EC in this mode of operation. This talk summarises the EC experi...

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...

    Civil engineering has begun for the new AWAKE experiment, which looks to push the boundaries of particle acceleration. This proof-of-principle experiment will harness the power of wakefields generated by proton beams in plasma cells, producing accelerator gradients hundreds of times higher than those used in current RF cavities.   Civil engineering works are currently ongoing at the AWAKE facility. As one of CERN's accelerator R&D experiments, the AWAKE project is rather unique. Like all of CERN's experiments, AWAKE is a collaborative endeavour with institutes and organisations participating around the world. "But unlike fixed-target experiments, where the users take over once CERN has delivered the facility, in AWAKE, the synchronised proton, electron and laser beams provided by CERN are an integral part of the experiment," explains Edda Gschwendtner, CERN AWAKE project leader. "So, of course, CERN's involvement in the project goes well...

Behavioral models have been proposed for the different kinds of Power Converters and the corresponding functionalities, with their parameters, variables and attributes have been identified. The resulting data structures have been presented using the ISO ASN.1 metalanguage, that permits universal representation independent of any computer environment. Implementations in the UNIX-based CERN accelerator control systems are under development.

  2. 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.

    The CERN Accelerator School (CAS) and MedAustron jointly organised a course on Accelerators for Medical Applications in Vösendorf, Austria between 26 May and 5 June 2015. The course was held at the Eventhotel Pyramide on the outskirts of Vienna, and was attended by 76 participants from 29 countries, coming from as far away as Canada, China, Lithuania, Thailand, Ukraine and Russia.       The intensive programme comprised 37 lectures. The emphasis was on using charged particle beams for cancer therapy and the programme began by covering the way in which particles interact with biological material, how this translates into the dose needed for treatment and how this dose is best delivered. The different accelerator options for providing the particles needed were then presented in some detail. The production of radioisotopes and how these are used for diagnostics and therapy was also covered, together with a look at novel acceleration techniques that may play a role i...

    Spotlight on CERN No. 3 Recruitment and professions at CERN Welcome to the Globe of Science and Innovation for this third edition of "Spotlight on CERN". When one thinks about professions at CERN, what springs to mind? Physicists? Engineers? In fact, the smooth operation of the Organisation relies on a diversity of professions and this in itself, poses a real challenge in terms of recruitment in CERN member states. Today, to tell us more about this challenge and about CERN professions in general, we welcome James Purvis, Head of the HR Recruitment, Programmes and Monitoring group, and Lore Taillieu, leader of the group's Recruitment section.

  13. CERN achievements in relativistic heavy ion collisions

    2015-01-01

    Full Text Available Twenty years after a Letter of Intent by the GSI and LBL groups for the “Study of particle production and target fragmentation in central 20Ne on Pb reactions, at 12 GeV per nucleon energy of the CERN PS external beam" [1], based on the results found by the NA45/CERES, NA49, NA50, and WA97/NA57 experiments at the SPS, CERN announced compelling evidence for the formation of a new state of matter in heavyion collisions at CERN-SPS energies [2]. Some of the experiments were indeed the 2nd or 3rd generation successors of the apparatuses originally proposed by the GSI-LBL collaboration. Actually, the CERN ion program initiated at the SPS with the acceleration of oxygen ions at 60 and 200 GeV/nucleon only in 1986, and continued with sulphur ions at 200 GeV/nucleon up to 1993. The rest is history: lead-ion beams at 160 GeV/nucleon became available at the SPS in 1994; the LHC accelerated and collided lead beams at a center of mass energy per nucleon pair √sNN = 2.76 TeV in 2010. Heavy ion physics is definitely in the future program of CERN: ALICE will operate a major upgrade of its detectors during the second long shutdown of the LHC, in 2018-2019, and the associated physics program will span the third and fourth LHC runs, till late 2020s.

    Consolidating phonebooks at CERN We have had many phonebooks in the past, Xwho (now decommissioned), the NICE phonebook on Windows PCs, and more recently the web site people.cern.ch. However, diversity doesn’t always equate to improved efficiency or quality. So in order to reduce the maintenance effort and to improve the user experience, we have consolidated these various phonebooks into a single web application: phonebook.cern.ch Motivations for change The NICE Phonebook was introduced in the year 2000 when Windows 95 was the major desktop platform. Since then, a lot has changed not only in technology and the desktop landscape but also in the variety of devices used to access the data (notably smartphones and tablets). Updating the NICE phonebook is slow. Once the master database is modified it can take up to two days for the data to propagate to the application. Thus, we are now planning the retirement of the NICE phonebook application. The new Phonebook.cern.ch The new phonebook.cern.ch...

    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. "It's contemporary modern art, and that's sometimes difficult to take in." For more information on this thought-provoking show, see: htt...

    Rania Python is twenty-five years old and in the second year of her Master's Degree at Geneva University's School of Translation and Interpreting (ETI); she arrived at CERN on 16 August to start a two-month placement in the Translation and Minutes Service. Nothing remarkable about that, you might say…until you find out that she's blind.   One of the first questions that springs to mind when you hear this is: "how does she manage?" Happily, modern computer technology makes it possible for Rania to work like any other translator. "I have two ways of reading a text on my computer," Rania explains. "Either I use the voice function, where the text on screen is dictated by a voice-synthesis programme, or I use my special braille terminal (see photo and box) which plugs into a USB port and reproduces the on-screen text under my fingers." Rania brought all these devices with her to CERN so that she could get straight to work on the first d...

    2000-07-01

    Two years ago John Kinchin and myself were lucky enough to attend the Goldsmith's particle physics course. As well as many interesting lectures and activities, this course included a visit to CERN. To most physics teachers CERN is Mecca, a hallowed place where gods manipulate and manufacture matter. The experience of being there was even better. Alison Wright was an enthusiastic and very knowledgeable host who ensured the visit went smoothly and we all learned a lot. While we were there, John and I discussed the possibility of bringing a party of A-level students to see real physics in action. In February of this year we managed it. 33 students from two schools, Boston Grammar School and Northampton School for Boys, and four staff left England and caught the 2 am ferry to France. Many hours and a few `short cuts' later we arrived at our hotel in St Genis, not far from CERN. The first day was spent sight-seeing in Lausanne and Geneva. The Olympic museum in Lausanne is well worth a visit. Unfortunately, the famous fountain in Geneva was turned off, but then you can't have everything. The following morning we turned up at CERN late due to the coach's brakes being iced up! We were met once again by Alison Wright who forgave us and introduced the visit by giving an excellent talk on CERN, its background and its reason for existing. At this point we met another member of our Goldsmith's course and his students so we joined forces once again. We then piled back into the coach to re-cross the border and visit ALEPH. ALEPH is a monster of a detector 150 m below ground. We divided into four groups, each with a very able and knowledgeable guide, and toured the site. The size and scale of the detector are awesome and the students were suitably impressed. We repeated the speed of sound experiment of two years ago at the bottom of a 150 m concrete shaft (320 m s-1), posed for a group photo in front of the detector (figure 1) and returned to the main site for lunch in

    The drift chambers of the former NA48 experiment have recently left CERN to be installed in the MPD experiment at the future NICA accelerator in Dubna, Russia. As a counterpart, the JINR Laboratory will produce drift chambers for the new NA62 experiment. This operation is a fruitful exchange of technology that profits both laboratories and enhances their collaboration.   On 22 July, in the occasion of the departure of the chambers from CERN, Mikhail Itkis (centre), acting Director of the JIINR visited the NA62 experimental area accompanied by Rolf Heuer (left), CERN Director General and Ferdinand Hahn, NA62 technical Co-ordinator. The NA48 drift chambers were overhauled in 2000 and employed until 2008. With a total of 110 kilometres of wire soldered to a very high degree of precision, the four drift chambers were a crucial element of the experimental kaon programme at CERN. The chambers are now moving to a new challenge as they will be re-used by the Multi Purpose Detector (MPD) experiment, under...

    The impact of CERN’s activities on the surrounding environment is carefully monitored by the Organization via a complete environmental monitoring programme, which is defined and run in agreement with the authorities of Switzerland and France. This programme covers both radiological and conventional aspects. So far the environmental impact of CERN was shown to be negligible. In particular, CERN’s radiological impact is a fraction of the variation of the natural exposure at different locations of the surrounding region. As the site of the Organization is on the territory of two countries and straddles the Swiss-French border, the implementation of its environmental policy requires specific procedures and a very transparent communication towards the Host States authorities and the public opinion. This paper reports the official CERN speech delivered for the opening of the international conference Enviroinfo 2004 that was held at CERN in October 2004.

    State-of-the-art techniques derived from particle accelerators, detectors, and physics computing are routinely used in clinical practice and medical research centers: from imaging technologies to dedicated accelerators for cancer therapy and nuclear medicine, simulations, and data analytics. Principles of particle physics themselves are the foundation of a cutting edge radiotherapy technique for cancer treatment: hadron therapy. This article is an overview of the involvement of CERN, the European Organization for Nuclear Research, in medical applications, with specific focus on hadron therapy. It also presents the history, achievements, and future scientific goals of the European Network for Light Ion Hadron Therapy, whose co-ordination office is at CERN.

    CERN. Geneva

    2004-01-01

    CERN is where the web was born, and remains a hothouse of innovation in information technology (IT). In this fourth First Tuesday @ CERN, we look at industrial partnership at CERN in the IT area from several different angles. The approach taken by CERN with software licencing - a very hot topic in the world of IT - will be discussed. The benefits that CERN hardware and software suppliers gain from working with CERN will be presented, and the CERN openlab, a new approach to industrial partnership at CERN, will be covered. A novel ingredient of this First Tuesday @ CERN is that it will be run in parallel with a similar event for the business community in London, and there will be webcast presentations between the Queen Elizabeth II Conference Centre in London and CERN during the event. Thus, First Tuesday @ CERN will take on a truly European dimension, to reflect CERN's European character. More information: http://www.rezonance.ch, or view the joint UK event program

In Switzerland, as in many other countries, this year has seen a long list of activities, celebrating the centenary of Einstein's 'Annus mirabilis'. Having formerly employed Einstein, the Swiss Federal Institute of Intellectual Property in Bern made its contribution by sponsoring a special 'study week' for young high-school students, under the tutorship of 'Schweizer Jugendforscht', an organisation which supports the scientific activities of very talented young people. The organisers chose 'Mission to Jupiter's Moon, Europa' as the general theme for this study week. From 2 to 8 October 2005 several groups of students (between 16 and 19 years old) had to investigate some mission-related questions, ranging from the choice of the orbit and different ways of explor...

    2015-01-01

    Though the Large Hadron Collider (LHC) at CERN is just at the start of a program expected to run for 20 additional years, CERN is studying the next generation of colliders, like the Compact Linear Collider (CLIC). This project proposes an electron-positron collider with a length close to 50 km and with a centre of mass energy of 3 TeV at the collision point. One of the main challenges is the sub-micrometric size of the beams, down to a few nanometres at the interaction point. As a consequence, the accelerator will require unprecedented nanometric tolerances of beam alignment. A series of several thousands components will have to be assembled, aligned at the micrometre level and most critically, stabilized actively at the nanometre level. PACMAN, a study on Particle Accelerator Components Metrology and Alignment to the Nanometre scale, is a Marie Curie Program supported by the European Commission (FP7 Program), creating a network of 16 Academic and Industrial Partners. The project is hosted at CERN and it offe...

    CERN Director-General Rolf Heuer (left) and JINR Director Alexei Sissakian (right). On Thursday 28 January, CERN Director-General Rolf Heuer and JINR Director Alexei Sissakian signed a new enlarged co-operation agreement to continue and enhance the scientific and technical co-operation of the two institutes in the field of high-energy physics. CERN and JINR have a long and successful history of collaboration extending back to the earliest days of their existence. The first informal meeting on international co-operation in the field of high-energy accelerators took place at CERN in 1959. It was attended by senior scientists from the United States, the USSR (including JINR) and CERN. Both JINR and CERN have played the role of a bridge between East and West for decades, contributing to the development of international scientific co-operation.

During his visit to CERN on 17 February, Liu Yanhua, Vice Minister of Science and Technology of the People's Republic of China, signed a new Co-operation Agreement with the Laboratory. The Agreement, which is valid for a period of five years and renewable, lays down the framework for the development of scientific and technological co-operation between CERN and China. This includes China's participation, as a non-Member State, in CERN's research projects as well as its main programmes. Robert Aymar and Liu Yanhua underlined that this Agreement will provide an excellent framework for close co-operation on the LHC Programme and Grid and accelerator technologies. Scientific co-operation between China and CERN is nothing new, as Chinese physicists already took part in the LEP experiments. Today, CERN's C...

    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...

Net practice eventually started in late July, which is probably why the results at the beginning of the season weren’t so good.

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.

    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 Bulletin

    2011-01-01

    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. With the incredible thirst for informati...

  6. 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...

    2002-01-01

    Aspects of LHC construction. The CERN Council, where the representatives of the 20 Member States of the Organization decide on scientific programmes and financial resources, held its 120th session on 14 December under the chairmanship of Prof. Maurice Bourquin (CH). CERN adjusts to the LHC Director-General, Luciano Maiani, stressed that CERN was now fully engaged in the LHC and outlined the first moves to react to the increased cost to completion of the LHC. The new accelerator is an extremely complex, high-tech project which CERN is building under very severe conditions. However, the technical challenges are solved and industrial production of accelerator elements, and installation are starting. Professor Maiani said that 2001 had been a very hard but decisive year for CERN. An important milestone had been passed during this meeting with the approval of the LHC dipole magnets contract, the last major contract for the accelerator. The new costs to completion of the LHC project are now clear. A first propos...

  9. Project management as a breakthrough at CERN

    Building and maintaining control systems for high-energy physics is becoming an increasingly complex and costly activity. The quickly evolving technology and the tight budget conditions require today a better management of our engineering activities. This situation led us to organize these activities as "projects" and to use modern project management practices already widely spread in industry. In this context, many aspects of the re-engineering of the controls infrastructure of the two CERN largest particle accelerators - SPS and LEP - as well as the supervision of the CERN wide technical services are fully conducted as projects with special control over the costs, resources, objectives, activities and maintenance aspects. This paper presents our experience in project-based management with special emphasis on its applicability in a research environment, the impact on the current working practices, and the potential benefits for the future. Some key concepts and techniques of project management are introduced...

    Zaharieva, Z

    2011-01-01

    The CERN Alarms System - LASER is a centralized service ensuring the capturing, storing and notification of anomalies for the whole accelerator chain, including the technical infrastructure at CERN. The underlying database holds the pre-defined configuration data for the alarm definitions, for the Operators alarms consoles as well as the time-stamped, run-time alarm events, propagated through the Alarms Systems. The article will discuss the current state of the Alarms database and recent improvements that have been introduced. It will look into the data management challenges related to the alarms configuration data that is taken from numerous sources. Specially developed Extract-Transform-Load (ETL) processes must be applied to this data in order to transform it into an appropriate format and load it into the Alarms database. The recorded alarms events together with some additional data, necessary for providing events statistics to users, are transferred to the long-term alarms archive.The article will cover...

  13. Remote video conferencing teaching from CERN

    For those of us who are teaching at a university, coming to CERN for a week means that someone else has to be found to teach our course. Recently, thanks to an initiative of CERN's Education Group who in collaboration with the IT department have buit a Remote Video Conference (VC) room for outreach communication with schools, I have been able to test teaching class back home whilst at the same time being at CERN! On Monday October 5, at 16:00, (10:00 at Indiana University), I attempted my first remote class. Of course, I could not do this alone. Back in the main auditorium in the physics Department, Hal Evans and Fred Luehring had rolled in a portable teleconference center, set up lecture demos and started a class computer. At CERN, Knut Bjorkli had the teaching center teleconference screen active, and had also connected to my class website when I arrived. The first day startup was a bit rocky - there were fire wall problems (?) that required that we connect to the Indiana VC unit rather than the other way a...

    European Physical Journal H is a journal published by Springer that focuses on the historical development of ideas in contemporary physics. Since 2009 it has partially replaced the journal "Annales de Physique" published by EDP sciences.   The journal recently published a special issue about CERN accelerators entitled "CERN's accelerators, experiments and international integration 1959-2009", with the former CERN Director-General, Herwig Schopper, as guest editor. The origin of this issue is a symposium that took place at CERN on 3-4 December 2009: "50 years of Nobel Memories in High-Energy Physics", for the 50th anniversary of the CERN Proton Synchrotron. Some of the contributions to this symposium became articles that are a real treasure for physicists and historians. Many of these are actually personal recollections from the main actors of the CERN accelerators. In addition, regular papers have been invited to make this ...

    This week saw the First International School on Laser Applications at Accelerators held in GANIL (France). Organised by the LA3NET project – of which CERN is a partner – the school was a singular opportunity for accelerator and laser physicists to meet and discuss the future of the merging areas.   As an EU-funded training network, LA3NET has brought together 27 partner institutes to train early stage researchers in the field of laser applications. Though the network kickedoff only a few months ago, it has already filled 15 of its 17 fellow positions, including three in CERN’s BE and EN Departments. The five-day International School on Laser Applications at Accelerators was the first big event organised by LA3NET, and united participants from both inside and outside the project. “This was the first time a school had linked laser and accelerator physics at such a fundamental level,” says Carsten P. Welsch, a former CERN fellow who now coordinates t...
