/ Barbagallo, Carmelo (IJCLab, Orsay ; U. Paris-Saclay) ; Barriere, Simon (CERN) ; Clement, Sebastien (CERN) ; Duchesne, Patricia (IJCLab, Orsay) ; Gerard, Romain Louis (CERN) ; Gerigk, Frank (CERN) ; Henry, James (Jefferson Lab) ; Kaabi, Walid (IJCLab, Orsay) ; Maurin, Pierre (CERN) ; Olivier, Gilles (IJCLab, Orsay) et al.
Superconducting Radio-Frequency (SRF) linac cryomodules are foreseen for the high-current multi-turn energy recovery linac PERLE (Powerful Energy Recovery Linac for Experiments). Coaxial higher order mode (HOM) couplers are the primary design choice to absorb beam-induced power and avoid beam instabilities. [...]

High Energy Phys.) ; Koratzinos, Michael (PSI, Villigen ; U. Malta) ; List, Benno (DESY) ; Litvinenko, Vladimir (SUNY, Stony Brook) ; Nanni, Emilio (SLAC) et al.
A special session at eeFACT’22 reviewed the electrical power budgets and luminosity risks for eight proposed future Higgs and electroweak factories (CCC, CEPC, CERC, CLIC, FCC-ee, HELEN, ILC, and RELIC) and, in comparison, for a lepton-hadron collider (EIC) presently under construction. We report highlights of presentations and discussions..
