Abstract
The injector cryomodule for the compact energy recovery linac (cERL) is under development at KEK. The cryomodule with 3L-band 2-cell cavities was built in June 2012. A prototype 2-cell cavity and three other 2-cell cavities with five higher-order-mode (HOM) couplers for actual operation were fabricated in May 2011. The vertical tests of these cavities were carried out after standard surface preparation at the KEK Superconducting accelerator Test Facility (KEK-STF) from October 2010 to March 2012. Radio-frequency feedthroughs with high thermal conductivity for the HOM coupler were also developed to achieve 12.5MV/m CW operation in the cryomodule. A Kyocera NR-type connector was modified to connect to this target. The results of vertical tests of the 2-cell cavities to measure their feedthrough performance will be reported in this paper.
