Future Circular Collider Feasibility Study Report Volume 2 : Accelerators, technical infrastructure and safety
/ Benedikt, M. (ed.) (CERN) ; Zimmermann, F. (CERN) ; Auchmann, B. (CERN ; PSI, Villigen) ; Bartmann, W. (CERN) ; Burnet, J.P. (CERN) ; Carli, C. (CERN) ; Chancé, A. (IRFU, Saclay) ; Craievich, P. (PSI, Villigen) ; Giovannozzi, M. (CERN) ; Grojean, C. (DESY ; Humboldt U., Berlin) et al.
In response to the 2020 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Feasibility Study was launched as an international collaboration hosted by CERN. The FCC ‘integrated programme’, described in this report, in a first stage consists of a highest-luminosity electron-positron collider, FCC-ee, serving as Higgs, top and electroweak factory, with a subsequent energy-frontier proton-proton collider, FCC-hh, as the second stage. The FCC-ee is designed to operate at four baseline centre-of-mass energies, corresponding to the Z pole, the WW pair production threshold, the ZH production peak, and the top/anti-top production threshold, always delivering the highest possible luminosities to four experiments.

Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how the FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model.

Data-Driven Risk Matrices for CERN’s Accelerators
/ Cartier-Michaud, Thomas (CERN) ; Apollonio, Andrea (CERN) ; Blarasin, Gennaro (CERN) ; Todd, Benjamin (CERN) ; Uythoven, Jan (CERN)
A risk matrix is a common tool used in risk assessment, defining risk levels with respect to the severity and probability of the occurrence of an undesired event. Risk levels can then be used for different purposes, e.g. [...]

FGC3.2: A New Generation of Embedded Controls Computer for Power Converters at CERN
/ Page, Stephen (CERN) ; Ghabrous Larrea, Carlos (CERN) ; King, Quentin (CERN) ; Todd, Benjamin (CERN) ; Uznanski, Slawosz (CERN) ; Zielinski, Dariusz (CERN)
Modern power converters (power supplies) at CERN are controlled by devices known as Function Generator/Controllers (FGCs), which are embedded computer systems providing function generation, current and field regulation, and state control. FGCs were originally conceived for the LHC in the early 2000s, though later generations are now increasingly being deployed in the accelerators in the LHC Injector Chain (Linac4, Booster, Proton Synchrotron and SPS) to replace obsolete equipment.

Adaptation of CERN Power Converter Controls for Integration into Other Laboratories using EPICS and TANGO
/ Page, Stephen (CERN) ; Afonso, Joao (CERN) ; Ghabrous Larrea, Carlos (CERN) ; Herttuainen, Joni (CERN) ; King, Quentin (CERN) ; Todd, Benjamin (CERN)
Modern power converters (power supplies) at CERN use proprietary controls hardware, which is integrated into the wider control system by software device servers developed specifically for the CERN environment, built using CERN libraries and communication protocols. There is a growing need to allow other HEP laboratories to make use of power converters that were originally developed for CERN and, consequently, a desire to allow for their efficient integration into control systems used at those laboratories, which are generally based upon either of the EPICS and Tango frameworks. [...]

Chapter 6B: Warm powering of the superconducting circuits
/ Martino, M (CERN) ; Burnet, J-P (CERN) ; Cerqueira Bastos, M (CERN) ; Herrero Gonzales, V R (CERN) ; Kuczerowski, N (CERN) ; Pittet, S (CERN) ; Thiesen, H (CERN) ; Thurel, Y (CERN) ; Todd, B (CERN) ; Yammine, S (CERN)
The warm powering of the HL-LHC involves the new circuits of the Inner Triplets and the Separation/Recombination magnets in Point 1 and Point 5, the powering of the 11 T magnets in Point 7, and the final R2E consolidation phase in LS3. The LHC was built with modular power converters to facilitate maintenance and integrate the redundancy principle. [...]
