Abstract

Coaxial type couplers are adopted in many superconducting radio-frequency (SRF) cavities to suppress higher order modes for beam dynamics and cryogenic loads issues. HERA (Hadron-Electron Ring Accelerator) and TTF (Tesla Test Facility) are equipped with this type of HOM couplers and showed successful performances. It is, however, under suspicion that a limitation or a fault could be initiated from this type of coupler at certain unwanted combinations between cavity conditions and engineering designs of the coupler. Possible scenarios that could result in faults are under investigations and are summarized in this paper based on observations in the SNS (Spallation Neutron Source) SRF cavities.
