The FCC-ee Interaction Region Magnet Design / Koratzinos, M (Geneva U.) ; Blondel, A (Geneva U.) ; Bogomyagkov, A (Novosibirsk, IYF) ; Sinyatkin, S (Novosibirsk, IYF) ; Benedikt, M (CERN) ; Holzer, B (CERN) ; van Nugteren, J (CERN) ; Zimmermann, F (CERN) ; Oide, K (KEK, Tsukuba)
The design of the region close to the interaction point of the FCC-ee experiments is especially challenging. The beams collide at an angle (+-15 mrad) in the high-field region of the detector solenoid. [...]

Beam dynamics issues in the FCC / Bartmann, Wolfgang (CERN) ; Benedikt, Michael (CERN) ; Besana, Maria Ilaria (CERN) ; Bruce, Roderik (CERN) ; Bruning, Oliver (CERN) ; Buffat, Xavier (CERN) ; Burkart, Florian (CERN) ; Burkhardt, Helmut (CERN) ; Calatroni, Sergio (CERN) ; Cerutti, Francesco (CERN) et al.
The international Future Circular Collider (FCC) study is designing hadron, lepton and lepton-hadron colliders based on a new 100 km tunnel in the Geneva region. The main focus and ultimate goal of the study are high luminosity proton-proton collisions at a centre-of-mass energy of 100 TeV, using 16 T Nb3Sn dipole magnets. [...]

ANSYS modeling of thermal contraction of SPL HOM couplers during cool-down / Papke, K (CERN)
During the cool-down the HOM coupler as well as the cavity inside the cryo module experience a thermal contraction. For most materials between room temperature and liquid helium temperatures, the changes in dimension are in the order of a few tenths of a percent change in volume. [...]
