Numerical simulations of energy deposition caused by 50 MeV—50 TeV proton beams in copper and graphite targets / Nie, Y (CERN) ; Schmidt, R (CERN) ; Chetvertkova, V (GSI Helmholtzzentrum für Schwerionenforschung) ; Rosell-Tarrago, G (University of Barcelona) ; Burkart, F (CERN) ; Wollmann, D (CERN)
The conceptual design of the Future Circular Collider (FCC) is being carried out actively in an international collaboration hosted by CERN, for the post–Large Hadron Collider (LHC) era. The target center-of-mass energy of proton-proton collisions for the FCC is 100 TeV, nearly an order of magnitude higher than for LHC. [...]

Updated parameters for HL-LHC aperture calculations for proton beams / Bruce, Roderik (CERN) ; Bracco, Chiara (CERN) ; De Maria, Riccardo (CERN) ; Giovannozzi, Massimo (CERN) ; Redaelli, Stefano (CERN) ; Tomas Garcia, Rogelio (CERN) ; Velotti, Francesco Maria (CERN) ; Wenninger, Jorg (CERN)
During the accelerator design, it is important to have a reliable way of estimating the available aperture, in order to ensure a sufficient beam clearing and avoid potentially limiting beam losses on the aperture. [...]

Comparison of coaxial higher order mode couplers for the CERN Superconducting Proton Linac study / Papke, Kai (CERN) ; Gerigk, Frank (CERN) ; Van Rienen, Ursula (IAE)
Higher order modes (HOMs) may affect beam stability and refrigeration requirements of superconducting proton linacs such as the Superconducting Proton Linac, which is studied at CERN. Under certain conditions beam-induced HOMs can accumulate sufficient energy to destabilize the beam or quench the superconducting cavities. [...]
