Cavity Clean Room Assembly
• Coupler Mounting Test
• Slow Pumping and N2 Purging
• Middle-position slide jack tuner with four guiding rods
• Helium vessel bellow and tuner flanges sagging when loose the support fixtures; will be restored when the tuner is installed.

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.
