Title: FERRITE-LINED HOM ABSORBER FOR THE E-COOL ERL

Abstract

An R&D Energy Recovery Linac (ERL) intended as step towards electron-cooling of RHIC-II is being constructed at this laboratory. The center piece of the project is the experimental 5-cell 703.75 MHz superconducting ECX cavity. Successful operation will depend on effective NOM suppression, and it is planned to achieve NOM damping exclusively with room temperature ferrite absorbers. A ferrite-lined pillbox test model with dimensions reflecting the operational unit was assembled and attached to the 5-cell copper cavity. The cavity resonances of the lowest dipole and monopole modes and their damping due to the ferrite were determined. The effective ferrite properties in a form portable to other structures were obtained from network analyzer measurements of the ferrite absorber models and their interpretation with the simulation code Microwave Studio.
