Simulations and First RF Measurements of Coaxial HOM Coupler Prototypes for PERLE SRF Cavities
/ 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. [...]
