  • CERN Courier–Digital Edition
    CERNMarch/April 2021 cerncourier.com COURIERReporting on international high-energy physics WELCOME CERN Courier – digital edition Welcome to the digital edition of the March/April 2021 issue of CERN Courier. Hadron colliders have contributed to a golden era of discovery in high-energy physics, hosting experiments that have enabled physicists to unearth the cornerstones of the Standard Model. This success story began 50 years ago with CERN’s Intersecting Storage Rings (featured on the cover of this issue) and culminated in the Large Hadron Collider (p38) – which has spawned thousands of papers in its first 10 years of operations alone (p47). It also bodes well for a potential future circular collider at CERN operating at a centre-of-mass energy of at least 100 TeV, a feasibility study for which is now in full swing. Even hadron colliders have their limits, however. To explore possible new physics at the highest energy scales, physicists are mounting a series of experiments to search for very weakly interacting “slim” particles that arise from extensions in the Standard Model (p25). Also celebrating a golden anniversary this year is the Institute for Nuclear Research in Moscow (p33), while, elsewhere in this issue: quantum sensors HADRON COLLIDERS target gravitational waves (p10); X-rays go behind the scenes of supernova 50 years of discovery 1987A (p12); a high-performance computing collaboration forms to handle the big-physics data onslaught (p22); Steven Weinberg talks about his latest work (p51); and much more.

This will be the first experiment to demonstrate proton-driven plasma wake- field acceleration. The 400 GeV proton beam from the CERN SPS will excite a wakefield in a plasma cell several meters in length. To probe the plasma wakefield, electrons of 10–20 MeV will be injected into the wakefield follow- ing the head of the proton beam. Simulations indicate that electrons will be accelerated to GeV energies by the plasma wakefield. The AWAKE spectrometer is intended to measure both the peak energy and energy spread of these accelerated electrons. Results of beam tests of the scintillator screen Figure 1: A 3D CAD image of the spectrometer system output are presented, along with tests of the resolution of annotated with distances along the z direction from the exit the proposed optical system.

Scientists from around the world go to The 600 MeV Synchrocyclotron (SC), built in CERN to seek answers to such fundamental 1957, was CERN’s first accelerator. It provided questions using particle accelerators and pushing beams for CERN’s first experiments in particle and nuclear the limits of technology. physics. In 1964, this machine started to concentrate on nuclear physics alone, leaving particle physics to the newer During February 2019, I was given a once in a lifetime and more powerful Proton Synchrotron. opportunity to be part of The Maltese Teacher Programme at CERN, which introduced me, as one of the participants, to cutting-edge particle physics through lectures, on-site visits, exhibitions, and hands-on workshops. Why do they do all this? The main objective of these type of visits is to bring modern science into the classroom. Through this report, my purpose is to give an insight of what goes on at CERN as well as share my experience with you students, colleagues, as well as the general public. The SC became a remarkably long-lived machine. In 1967, it started supplying beams for a dedicated radioactive-ion-beam facility called ISOLDE, which still carries out research ranging from pure What does “CERN” stand for? At an nuclear physics to astrophysics and medical physics. In 1990, intergovernmental meeting of UNESCO in Paris in ISOLDE was transferred to the Proton Synchrotron Booster, and the SC closed down after 33 years of service.

  • The AWAKE Acceleration Scheme for New Particle Physics Experiments at CERN
    AWAKE++: the AWAKE Acceleration Scheme for New Particle Physics Experiments at CERN W. Bartmann1, A. Caldwell2, M. Calviani1, J. Chappell3, P. Crivelli4, H. Damerau1, E. Depero4, S. Doebert1, J. Gall1, S. Gninenko5, B. Goddard1, D. Grenier1, E. Gschwendtner*1, Ch. Hessler1, A. Hartin3, F. Keeble3, J. Osborne1, A. Pardons1, A. Petrenko1, A. Scaachi3, and M. Wing3 1CERN, Geneva, Switzerland 2Max Planck Institute for Physics, Munich, Germany 3University College London, London, UK 4ETH Zürich, Switzerland 5INR Moscow, Russia 1 Abstract The AWAKE experiment reached all planned milestones during Run 1 (2016-18), notably the demon- stration of strong plasma wakes generated by proton beams and the acceleration of externally injected electrons to multi-GeV energy levels in the proton driven plasma wakefields. During Run 2 (2021 - 2024) AWAKE aims to demonstrate the scalability and the acceleration of elec- trons to high energies while maintaining the beam quality. Within the Physics Beyond Colliders (PBC) study AWAKE++ has explored the feasibility of the AWAKE acceleration scheme for new particle physics experiments at CERN. Assuming continued success of the AWAKE program, AWAKE will be in the position to use the AWAKE scheme for particle physics ap- plications such as fixed target experiments for dark photon searches and also for future electron-proton or electron-ion colliders. With strong support from the accelerator and high energy physics community, these experiments could be installed during CERN LS3; the integration and beam line design show the feasibility of a fixed target experiment in the AWAKE facility, downstream of the AWAKE experiment in the former CNGS area. The expected electrons on target for fixed target experiments exceeds the electrons on target by three to four orders of magnitude with respect to the current NA64 experiment, making it a very promising experiment in the search for new physics.

  • Beam–Material Interactions
    Beam–Material Interactions N.V. Mokhov1 and F. Cerutti2 1Fermilab, Batavia, IL 60510, USA 2CERN, Geneva, Switzerland Abstract This paper is motivated by the growing importance of better understanding of the phenomena and consequences of high-intensity energetic particle beam interactions with accelerator, generic target, and detector components. It reviews the principal physical processes of fast-particle interactions with matter, effects in materials under irradiation, materials response, related to component lifetime and performance, simulation techniques, and methods of mitigating the impact of radiation on the components and environment in challenging current and future applications. Keywords Particle physics simulation; material irradiation effects; accelerator design. 1 Introduction The next generation of medium- and high-energy accelerators for megawatt proton, electron, and heavy- ion beams moves us into a completely new domain of extreme energy deposition density up to 0.1 MJ/g and power density up to 1 TW/g in beam interactions with matter [1, 2]. The consequences of controlled and uncontrolled impacts of such high-intensity beams on components of accelerators, beamlines, target stations, beam collimators and absorbers, detectors, shielding, and the environment can range from minor to catastrophic. Challenges also arise from the increasing complexity of accelerators and experimental set-ups, as well as from design, engineering, and performance constraints. All these factors put unprecedented requirements on the accuracy of particle production predictions, the capability and reliability of the codes used in planning new accelerator facilities and experiments, the design of machine, target, and collimation systems, new materials and technologies, detectors, and radiation shielding and the minimization of radiation impact on the environment.

  • Accelerator Programme Evaluation Report
    OFFICIAL Accelerator Programme Evaluation Report ACCELERATOR PROGRAMME EVALUATION REPORT 1. Executive Summary 1.1. Accelerator science (i) enables advanced facilities that underpin fields as diverse as nuclear and particle physics, and physical and life sciences; and (ii) develops novel techniques that could revolutionise future research and lead to a wealth of applications. 1.2. Accelerator science within STFC is supported within the National Laboratories and by the Programmes Directorate (PD) programme. The PD programme funds accelerator R&D in universities via the UK’s two accelerator institutes (the Cockcroft and John Adams Institutes), and by fixed contribution to the Accelerator Science and Technology Centre (ASTeC) National Laboratory. 1.3. This review has evaluated the STFC PD funded Accelerators Programme under three financial scenarios (flat cash, and ±10%). The review includes a consideration of the breadth and balance of the programme and its sustainability. 1.4. We find that the UK performs world class accelerator science and is a valued and sought-after international partner. UK scientists lead international collaborations and working groups, develop innovative techniques, produce high impact papers, and leverage international investment in projects. UK accelerator institutes and universities provide world-class training and skilled graduates that move into industry and the public sector, 1.5. This world-leading expertise provides a basis to successfully leverage support and lead work in future projects. For example, the UK’s track record in cryomodules and targetry enabled the UK to successfully bid for BEIS funding and lead this work at Fermilab’s Long Baseline Neutrino Facility (LBNF). We note that this investment dwarfs PD’s total accelerator science budget, and that participation would not otherwise have been possible.

    Proceedings of the 2018 CERN–Accelerator–School course on Beam Instrumentation, Tuusula, (Finland) Beam Diagnostic Requirements: an Overview G. Kube Deutsches Elektronen Synchrotron (DESY), Hamburg, Germany Abstract Beam diagnostics and instrumentation are an essential part of any kind of ac- celerator. There is a large variety of parameters to be measured for observation of particle beams with the precision required to tune, operate, and improve the machine. In the first part, the basic mechanisms of information transfer from the beam particles to the detector are described in order to derive suitable per- formance characteristics for the beam properties. However, depending on the type of accelerator, for the same parameter, the working principle of a monitor may strongly differ, and related to it also the requirements for accuracy. There- fore, in the second part, selected types of accelerators are described in order to illustrate specific diagnostics needs which must be taken into account before designing a related instrument. Keywords Particle field; beam signal; electron/hadron accelerator; instrumentation. 1 Introduction Nowadays particle accelerators play an important role in a wide number of fields, the number of acceler- ators worldwide is of the order of 30000 and constantly growing. While most of these devices are used for industrial and medical applications (ion implantation, electron beam material processing and irradia- tion, non-destructive inspection, radiotherapy, medical isotopes production, :::), the share of accelerators used for basic science is less than 1 % [1]. In order to cover such a wide range of applications different accelerator types are required. As an example, in the arts, the Louvre museum utilizes a 2 MV tandem Pelletron accelerator for ion beam anal- ysis studies [2].
