Abstract
The KEK high gradient test facility is described. Results are given of tests made on two 22-cell TW sections - one 'KEK' made by Japanese in dustry and the other 'CERN' made using technology developed for CLIC. The KEK structure was conditioned to an average accelerating gradient E(av) of 68 MV/m in 600 hours. The CERN structure reached 85 MV/m (a p eak field level of 138 MV/m) in 50 hours - these fields were limited b y the power available from the klystron. The dark current at 50 MV/m w as less than a few mu A for the CERN section but 20 to 30 mu A for the KEK section.
