15. 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 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 respectively.
