| | As part of the coordinated U.S. effort to build up SRF infrastructure
for the ILC, the Cornell SRF lab has developed
tools and procedures for 9-cell 1.3 GHz cavity processing
and vertical testing. Steps performed with 9-cell cavities
at Cornell include tuning for field flatness, vertical electropolishing
(or BCP if desired), high-pressure rinsing in
ultra-pure water, baking at 110C, and RF testing at 2K in a
vertical cryostat. Since spring 2006, Cornell has performed
ILC cavity processing/testing cycles at a rate of about one
per month. We summarize methods, results, and possible
next steps. | |
