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.

Design and first results of a cryogenic beam loss monitor installed at the LHC
/ Effinger, Ewald (CERN) ; Morales Vigo, Sara (CERN) ; Salvachua, Belen (CERN) ; Storey, James (CERN) ; Zamantzas, Christos (CERN) ; Griesmayer, Erich (TU Vienna ; CIVIDEC)
The Large Hadron Collider (LHC) is equipped with NiTb superconducting magnets operating at the cryogenic temperature of 2.9 K. A tiny fraction of proton beam at 7 TeV impacting the magnet coils has the potential to generate enough heat, leading to the loss of superconductivity in the magnets. [...]

Benchmarking power deposition from fast losses of heavy-ion beams at the onset of LHC Run 3
/ Rodin, Volodymyr (CERN) ; Lechner, Anton (CERN) ; Salvachua, Belen (CERN) ; Mirarchi, Daniele (CERN) ; Esposito, Luigi Salvatore (CERN) ; D'Andrea, Marco (CERN) ; Schoofs, Philippe (CERN) ; Bruce, Roderik (CERN) ; Cai, Rongrong (CERN) ; Morales Vigo, Sara (CERN) et al.
In 2023, the LHC started its Run 3 operation with $^{208}\text{PB}^{82+}$ beams at 6.8 ZTeV, with a substantially higher number of bunches compared to past runs. Several new hardware systems were used operationally for the first time with high-intensity beams, including bent crystal collimators in the betatron cleaning insertion. [...]
