Abstract

A 5-cell 650 MHz SRF cavity was design for eRHIC high current SRF linac. One Cu cavity was fabricated for HOM damping study, and one Nb cavity was fabricated for SRF performance study with various post-processing procedures. The SRF performance study includes both high Q-value study (at gradient of 15 ~ 18 MV/m) and high gradient study (> 26 MV/m). This paper reports the HOM measurements results on Cu cavity and first result of vertical test on the Nb cavity.
