Simulation of Synchrotron Radiation for the CERN Highest-Energy Accelerators / Guillermo Canton, Gerardo (CINVESTAV Merida)
In circular accelerators at energies in the order of TeV, synchrotron radiation (SR) is very high, even in a hadron beam. SR could be regarded as an important heat load to the cryogenic system cooling the superconducting electromagnets. [...]

Compensation of Synchrotron Radiation at Top Energy in the FCC-hh / Haas, Alexander (Vienna University of Technology (AT)) ; Timko, Helga (CERN)
To counteract the significant synchrotron radiation damping in the FCC-hh, a continuous longitudinal emittance blow-up is foreseen at top energy. [...]

Emittance growth from luminosity burn-off in future hadron colliders / Tomás, R (CERN) ; Keintzel, J (CERN) ; Papadopoulou, S (CERN)
Future hadron colliders aim at producing larger integrated luminosities by burning-off an increased fraction of the bunch particles. This burn-off removes particles unevenly in the bunch distribution generating an emittance growth. [...]

Design of the future circular hadron collider beam vacuum chamber / Bellafont, I (CELLS - ALBA, LLS ; CERN) ; Morrone, M (CERN) ; Mether, L (Ecole Polytechnique, Lausanne ; CERN) ; Fernández, J (Madrid, CIEMAT ; CERN) ; Kersevan, R (CERN) ; Garion, C (CERN) ; Baglin, V (CERN) ; Chiggiato, P (CERN) ; Pérez, F (CELLS - ALBA, LLS)
EuroCirCol is a conceptual design study of a post-LHC, Future Circular Hadron Collider (FCC-hh) which aims to expand the current energy and luminosity frontiers. The vacuum chamber of this 100 TeV, 100 km collider, will have to cope with unprecedented levels of synchrotron radiation linear power for proton colliders, 160 times higher than in the LHC for baseline parameters, releasing consequently much larger amounts of gas into the system. [...]

Availability and critical systems of the Future Circular Electron–Positron Collider / Niemi, Arto (CERN) ; Penttinen, Jussi-Pekka (Ramentor Oy, Tampere)
The Future Circular Electron–Positron Collider (FCC-ee) is planned to be the world’s largest particle collider and a precision instrument to study the heaviest known particles. Achieving substantial physics results requires producing high amounts of integrated luminosity, which calls for sufficient machine availability. [...]

SixTrack V and runtime environment / De Maria, R (CERN) ; Andersson, J (CERN) ; Berglyd Olsen, V K (CERN) ; Field, L (CERN) ; Giovannozzi, M (CERN) ; Hermes, P D (CERN) ; Høimyr, N (CERN) ; Kostoglou, S (CERN) ; Iadarola, G (CERN) ; Mcintosh, E (CERN) et al.
SixTrack is a single-particle tracking code for high-energy circular accelerators routinely used at CERN for the Large Hadron Collider (LHC), its luminosity upgrade (HL-LHC), the Future Circular Collider (FCC) and the Super Proton Synchrotron (SPS) simulations. The code is based on a 6D symplectic tracking engine, which is optimized for long-term tracking simulations and delivers fully reproducible results on several platforms. [...]

Impact of flux jumps in future colliders / Coello de Portugal, J (CERN) ; Tomás, R (CERN) ; Fiscarelli, L (CERN) ; Gamba, D (CERN) ; Martino, M (CERN)
Type-II superconductors, like the Nb3Sn used in the new HL–LHC quadrupole triplet and 11 T dipoles or FCC dipoles, are known to show an unstable behavior during magnetic-field ramps. This paper presents an analysis of the possible effects on the beam dynamics of this behavior of the magnets, with a focus on emittance blow-up..
