The performance of the new beamlines will be optimized in terms of maximum momentum and choice of particle type.

Statistical sensitivities could approach 10<sup>−29</sup><em>e </em>cm. The challenge will be to reduce systematic errors to similar levels. The ring will be adjusted to preserve the spin polarization, initially parallel to the particle velocity, for times in excess of 15 min. Large radial electric fields, acting through the EDM, will rotate the polarization from the longitudinal to the vertical direction. The slow increase in the vertical polarization component, detected through scattering from a target, signals the EDM.</p> <p>The project strategy is outlined. A stepwise plan is foreseen, starting with ongoing COSY activities that demonstrate technical feasibility. Achievements to date include reduced polarization measurement errors, long horizontal plane polarization lifetimes, and control of the polarization direction through feedback from scattering measurements.

Béjar Alonso, O. Brüning, P. Fessia, M. Lamont, L. Rossi, L. Tavian, M. Zerlauth</strong></p> <p><br>The Large Hadron Collider (LHC) is one of the largest scientific instruments ever built. Since opening up a new energy frontier for exploration in 2010, it has gathered a global user community of about 9000 scientists working in fundamental particle physics and the physics of hadronic matter at extreme temperature and density. To sustain and extend its discovery potential, the LHC will need a major upgrade in the 2020s. This will increase its instantaneous luminosity (rate of collisions) by a factor of five beyond the original design value and the integrated luminosity (total number of collisions) by a factor ten. The LHC is already a highly complex and exquisitely optimised machine so this upgrade must be carefully conceived and will require new infrastructures (underground and on surface) and over a decade to implement. The new configuration, known as High Luminosity LHC (HL-LHC), relies on a number of key innovations that push accelerator technology beyond its present limits. Among these are cutting-edge 11–12 Tesla superconducting magnets, compact superconducting cavities for beam rotation with ultra-precise phase control, new technology and physical processes for beam collimation and 100 metre-long high-power superconducting links with negligible energy dissipation, all of which required several years of dedicated R&D effort on a global international level.</p> <p>The present document describes the technologies and components that will be used to realise the project and is intended to serve as the basis for the detailed engineering design of the HL-LHC.</p> <p>ISBN 978-92-9083-586-8 (paperback), ISBN 978-92-9083-587-5 (PDF). </p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/125"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_125_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/125"> A primary electron beam facility at CERN—eSPS: Conceptual design report </a> <div class="series"> Vol. 8 (2020) </div> </h2> <div class="description"> <p><strong>Editors: Torsten Åkesson and Steinar Stapnes</strong></p> <p>The design of a primary electron beam facility at CERN is described. The study has been carried out within the framework of the wider Physics Beyond Colliders study. It re-enables the Super Proton Synchrotron (SPS) as an electron accelerator, and leverages the development invested in Compact Linear Collider (CLIC) technology for its injector and as an accelerator research and development infrastructure. The facility would be relevant for several of the key priorities in the 2020 update of the European Strategy for Particle Physics, such as an electron-positron Higgs factory, accelerator R&D, dark sector physics, and neutrino physics. In addition, it could serve experiments in nuclear physics. The electron beam delivered by this facility would provide access to light dark matter production significantly beyond the targets predicted by a thermal dark matter origin, and for natures of dark matter particles that are not accessible by direct detection experiments. It would also enable electro-nuclear measurements crucial for precise modelling the energy dependence of neutrino-nucleus interactions, which is needed to precisely measure neutrino oscillations as a function of energy. The implementation of the facility is the natural next step in the development of X-band high-gradient acceleration technology, a key technology for compact and cost-effective electron/positron linacs. It would also become the only facility with multi-GeV drive bunches and truly independent electron witness bunches for plasma wakefield acceleration. A second phase capable to deliver positron witness bunches would make it a complete facility for plasma wakefield collider studies. <br>The facility would be used for the development and studies of a large number of components and phenomena for a future electron-positron Higgs and electroweak factory as the first stage of a next circular collider at CERN, and its cavities in the SPS would be the same type as foreseen for such a future collider. The operation of the SPS with electrons would train a new generation of CERN staff on circular electron accelerators. The facility could start operation in about five years, and would operate in parallel and without interference with Run 4 of the LHC.</p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/121"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_121_en_US.jpg" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/121"> Linac4 design report </a> <div class="series"> Vol. 6 (2020) </div> </h2> <div class="description"> <p><strong>Editor: Maurizio Vretenar</strong></p> <p>Linear accelerator 4 (Linac4) is designed to accelerate negative hydrogen ions for injection into the Proton Synchrotron Booster (PSB). It will become the source of proton beams for the Large Hadron Collider (LHC) after the long shutdown in 2019–2020. Linac4 will accelerate H– ions, consisting of a hydrogen atom with an additional electron, to 160 MeV energy and then inject them into the PSB, which is part of the LHC injection chain. The new accelerator comprises an ion source and four types of accelerating structures. The particles are accelerated first to 3 MeV energy by a Radio-Frequency Quadrupole (RFQ), then to 50 MeV by three Drift Tube Linacs (DTL) tanks, then to 100 MeV by seven Cell-Coupled Drift Tube Linac (CCDTL) modules, and finally to 160 MeV by twelve Pi-Mode Structures (PIMS). A chopper line placed between the RFQ and the first DTL tank modulates the linac beam at the PSB injection frequency. Linac4 includes transfer and measurement lines up to the PSB injection, where the ions are stripped of their two electrons to leave only protons. Linac4 is 76 metres long and located 12 metres below ground. The first low-energy beams were produced in 2013 and after the commissioning of all accelerating structures the milestone energy of 160 MeV was reached in 2016. Linac4 will be connected to the PSB during the long shutdown of 2019–20, after which it will replace the 50 MeV Linac2 as source of protons for the LHC. The Linac4 is a key element in the project to increase the luminosity of the LHC during the next decade. </p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/112"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_112_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/112"> LHC fixed target experiments: Report from the LHC Fixed Target Working Group of the CERN Physics Beyond Colliders Forum </a> <div class="series"> Vol. 4 (2020) </div> </h2> <div class="description"> <p><strong>Corresponding editor: </strong><a href="mailto:Stefano.Redaelli@cern.ch"><strong>Stefano.Redaelli@cern.ch</strong></a><br></p> <p>Several fixed-target experiments at the LHC are being proposed and actively studied.

A similar scheme without the second crystal or other schemes with more conventional solid or gas targets have been proposed to study hadronic matter and the quark-gluon plasma, as well as to provide inputs to cosmic ray physics. Most notably, an upgrade of the existing and already productive LHCb gas target (SMOG), which would make use of a storage cell, has been proposed, designed, and extensively reviewed. The implementation in LHCb of a polarised gas target, based on the storage cell technique, was also discussed, motivated by the nucleon-spin study. The status of these proposals, their technical feasibility and impacts on the LHC machine have been studied in the LHC Fixed Target Working Group of the Physics Beyond Collider forum at CERN.

A. Blondel, J. Gluza, S. Jadach, P. Janot and T. Riemann</strong><br></p><p>The Future Circular Collider (FCC) at CERN, a proposed 100 km circular facility with several colliders in succession, culminates in a 100 TeV proton–proton collider. It offers a vast new domain of exploration in particle physics, with orders-of-magnitude advances in terms of precision, sensitivity, and energy. The implementation plan published in 2018 foresees, as a first step, an electroweak factory electron–positron collider. This high-luminosity facility, operating at centre-of-mass energies between 90 and 365 GeV, will study the heavy particles of the Standard Model (SM), Z, W, and Higgs bosons, and top quarks with unprecedented accuracy. The physics programme offers great discovery potential: (i) through precision measurements, (ii) through sensitive searches for symmetry violations, forbidden, or extremely rare decays, and (iii) through the search for direct observation of new particles with extremely small couplings. The electroweak factory e<sup>+</sup>e<sup>-</sup> collider constitutes a real challenge to the theory and to precision calculations, triggering the need for the development of new mathematical methods and software tools. A first workshop in 2018 focused on the first FCC-ee stage, the Tera-Z, and confronted the theoretical status of precision Standard Model calculations on the Z boson resonance to the experimental demands. The second workshop, in January 2019, extended the scope to the next stages, with the production of W bosons (FCC-ee-W), the Higgs boson (FCC-ee-H), and top quarks (FCC-ee-tt). In particular, the theoretical precision in the determination of the crucial input parameters, αQED, αQCD, MW, and mt, at the level of FCC-ee requirements was thoroughly discussed. The requirements on Standard Model theory calculations were spelt out, so as to meet the demanding accuracy of the FCC-ee experimental potential. The discussion of innovative methods and tools for multiloop calculations was deepened. Furthermore, phenomenological analyses beyond the Standard Model were discussed, including effective theory approaches. The reports of 2018 and 2019 serve as white papers of the workshop results and subsequent developments. </p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/106"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_106_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/106"> SPS Beam Dump Facility: Comprehensive Design Study </a> <div class="series"> Vol. 2 (2020) </div> </h2> <div class="description"> <p><strong>Editors: M.

Possible options include searches for very weakly interacting particles predicted by Hidden Sector models, and flavour physics measurements. Following the first evaluation of the BDF in 2014–2016, CERN management launched a Comprehensive Design Study over three years for the BDF. The BDF study team has executed an in-depth feasibility study of proton delivery to target, the target complex, and the underground experimental area, including prototyping of key subsystems and evaluations of radiological aspects and safety. A first iteration of detailed integration and civil engineering studies has been performed to produce a realistic schedule and cost.

Its aim was to study the quark structure of the nucleon through deep inelastic muon scattering. Two seminal discoveries were made; the EMC effect and the spin crisis. In this paper the history of the collaboration from beginning to end is described. The appendices describe some of the difficulties met during the development and performance of the experiments as well as a description of some of the social interactions in the collaboration.</p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/90"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_90_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/90"> Study on the career trajectories of people with a working experience at CERN </a> <div class="series"> Vol. 4 (2019) </div> </h2> <div class="description"> <p>This document describes the results of a study, aiming to measure the impact of CERN and of its environment on the career of people who worked at the laboratory.

A preliminary report was presented and discussed at the Workshop on "New International Research Facilities for South East Europe" held in January 2017 at ICTP (Trieste). In March 2018 the Steering Committee came unanimously to the conclusion that the first facility to be built should be the HTR.

It is foreseen to be built and operated in three stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, respectively. It offers a rich physics program including direct searches as well as the probing of new physics through a broad set of precision measurements of Standard Model processes, particularly in the Higgs-boson and top-quark sectors. The precision required for such measurements and the specific conditions imposed by the beam dimensions and time structure put strict requirements on the detector design and technology. This includes low-mass vertexing and tracking systems with small cells, highly granular imaging calorimeters, as well as a precise hit-time resolution and power-pulsed operation for all subsystems. A conceptual design for the CLIC detector system was published in 2012. Since then, ambitious R&D programmes for silicon vertex and tracking detectors, as well as for calorimeters have been pursued within the CLICdp, CALICE and FCAL collaborations, addressing the challenging detector requirements with innovative technologies. This report introduces the experimental environment and detector requirements at CLIC and reviews the current status and future plans for detector technology R&D.</p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/59"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_59_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/59"> HIE-ISOLDE : Technical Design Report for the Energy Upgrade </a> <div class="series"> Vol. 1 (2018) </div> </h2> <div class="description"> <strong>edited by Y.

HIE-ISOLDE (High Energy and Intensity – ISOLDE) is an upgrade that aims to increase the facility’s energy and intensity reach, opening the way to new opportunities in multiple fields of physics: nuclear and atomic physics, astrophysics and fundamental interactions. This technical design report presents the HIE-ISOLDE energy upgrade as built. The report is divided in six parts. The first details the motivation behind the project, as well as previous experiences with post-accelerated beams at the facility. The second part presents the design of the new linear accelerator and its components, including cryomodules, superconducting cavities and solenoids, while the third focuses on beam dynamics. General services and systems are presented in the fourth part, while the fifth and sixth concern safety procedures and commissioning respectively. </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/66"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_66_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/66"> The Compact Linear Collider (CLIC) - 2018 Summary Report </a> <div class="series"> Vol. 2 (2018) </div> </h2> <div class="description"> <p><strong>Corresponding editors</strong>: Philip N.

Following the CLIC conceptual design published in 2012, this report provides an overview of the CLIC project, its current status, and future developments. It presents the CLIC physics potential and reports on design, technology, and implementation aspects of the accelerator and the detector. CLIC is foreseen to be built and operated in stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, respectively. CLIC uses a two-beam acceleration scheme, in which 12 GHz accelerating structures are powered via a high-current drive beam. For the first stage, an alternative with X-band klystron powering is also considered. CLIC accelerator optimisation, technical developments and system tests have resulted in an increased energy efficiency (power around 170 MW) for the 380 GeV stage, together with a reduced cost estimate at the level of 6 billion CHF. The detector concept has been refined using improved software tools. Significant progress has been made on detector technology developments for the tracking and calorimetry systems. A wide range of CLIC physics studies has been conducted, both through full detector simulations and parametric studies, together providing a broad overview of the CLIC physics potential. Each of the three energy stages adds cornerstones of the full CLIC physics programme, such as Higgs width and couplings, top-quark properties, Higgs self-coupling, direct searches, and many precision electroweak measurements. The interpretation of the combined results gives crucial and accurate insight into new physics, largely complementary to LHC and HL-LHC. The construction of the first CLIC energy stage could start by 2026. First beams would be available by 2035, marking the beginning of a broad CLIC physics programme spanning 25-30 years.</p> </div> </div><!-- .obj_issue_summary --> </li> <li> <div class="obj_issue_summary"> <a class="cover" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/71"> <img src="https://e-publishing.cern.ch/public/journals/9/cover_issue_71_en_US.png" alt=""> </a> <h2> <a class="title" href="https://e-publishing.cern.ch/index.php/CYRM/issue/view/71"> The CLIC potential for new physics </a> <div class="series"> Vol. 3 (2018) </div> </h2> <div class="description"> <p><strong>Corresponding editors: </strong>J. de Blas, R.

It combines the benefits of the clean environment of e+e− colliders with operation at high centre-of-mass energies, allowing to probe scales beyond the reach of the Large Hadron Collider (LHC) for many scenarios of new physics. This places the CLIC project at a privileged spot in between the precision and energy frontiers, with capabilities that will significantly extend knowledge on both fronts at the end of the LHC era.

For an optimal exploitation of its physics potential, CLIC is foreseen to be built and operated in stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, for a site length ranging between 11 km and 50 km. CLIC uses a Two-Beam acceleration scheme, in which normal-conducting high- gradient 12 GHz accelerating structures are powered via a high-current Drive Beam. For the first stage, an alternative with X-band klystron powering is also considered.
