  1. IHEP Cryomodule Status Jiyuan Zhai On behalf of the IHEP ILC SRF R&D Team AWLC14, May 14, Fermilab

  2. Outline • IHEP ILC-TC1 Cryomodule Assembly • Horizontal Test Facilities • Cavity Fabrication

  3. IHEP ILC-TC1 Cryomodule • Short cryomodule with one low-loss large grain 9-cell cavity (VT 20MV/m, Q0=1.4E10) • Cylindrical magnetic shield inside helium vessel • STF type input coupler and tuner • Module assembly to complete in July 2014, horizontal test in 2015

  4. Cryomodule Assembly Assembly Hall in IHEP Building #2

  5. Cavity Clean Room Assembly

  6. Cavity Clean Room Assembly Beam Tube Assembly Gate Valve Assembly Cavity Assembly Prep Careful Clean Room Assembly Operations (PFFA)

  7. Cavity Clean Room Assembly • 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. • Coupler Mounting Test 2mm

  8. Outline • IHEP ILC-TC1 Cryomodule Assembly • Horizontal Test Facilities • Cavity Fabrication

  9. Horizontal Test Facility Layout IHEP Building #1 Cryogenic Plant In commissioning Power Source Deliver in end 2014 Tunnel Horizontal test & beam test Vertical test Dewar Deliver in September

  10. Cryogenic System in Commissioning Cold box and compressor: refrigeration 1000W@4.5K, liquefication: 284 L/h 2K pumps: 8000 m3/h @ 3100 Pa

  11. 1.3 GHz Klystron and Modulator Ordered • 1.3 GHz 5 MW Klystron and Marx Modulator will deliver in end 2014

  12. Outline • IHEP ILC-TC1 Cryomodule Assembly • Horizontal Test Facilities • Cavity Fabrication

  13. TESLA-like Cavity Fabrication • End groups EBW ongoing • Cavity EBW to be done in July • Process and test at KEK

  14. TESLA Cavity Production • HERT Company • FG TESLA 9-cell cavity • Pressing and EBW test and optimization • One prototype in 2014

  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 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.

  16. Thank you!
