TESLA-like Cavity Fabrication End groups EBW ongoing Cavity EBW to be done in July Process and test at KEK
TESLA Cavity Production HERT Company FG TESLA 9-cell cavity Pressing and EBW test and optimization One prototype in 2014
Summary IHEP ILC test cryomodule assembly is ongoing and will be finished in July 2014. Hardware preparation, environment and component cleanliness, vacuum, alignment and assembly procedures are studied and conducted carefully for cavity clean room assembly. Cryogenic system and power source will be ready in end 2014 for the module horizontal test. Prototype production of a fine grain TESLA-like 9-cell cavity and a fine grain TESLA 9-cell cavity will be done in mid and end 2014 respectively.
Thank you!
