Powered operation of Cryomodule 1 (CM-1) at the Fermilab SRF Beam Test Facility began in late 2010. Since then a series of tests first on the eight individual cavities and then the full cryomodule have been performed. We report on the results of these tests and lessons learned which will have an impact on future module testing at Fermilab.

Fermilab makes use of a single-cavity test cryostat to assess the performance of dressed superconducting RF cavities using pulsed high-power RF before they are assembled into a cryomodule. Cavity performance is evaluated in terms of accelerating gradient, unloaded quality factor, and field emission. The functionality of auxiliary components such as tuners and fundamental power couplers is also verified. The latest results from extensive testing of nine-cell 1.3 GHz cavities are presented here, along with a discussion of future extensions of the horizontal test program to include 650 MHz cavities and continuous wave testing.

S1-Global collaborative project by joint efforts of INFN, DESY, FNAL, SLAC and KEK, finished successfully at KEK- STF on February in 2011, is a crucial project for ILC. For this project, 8 SRF cavities, 2 from DESY, 2 from FNAL and 4 from KEK, were installed into one cryomodule with the thermal shields and the cooling pipes of liquid helium and nitrogen, cooled down to 2K totally three times, and cold-tested by using the three different frequency tuning systems (Blade tuner from INFN/FNAL, Saclay tuner from DESY and Slide-Jack tuner from KEK) and two types of input couplers (TTF III from DESY and STF#2 from KEK). During the cold test with high power, cavity performance, LFD (Lorentz Force Detuning) compensation by Piezo actuator, simultaneous 7 SRF cavities operation, dynamic heating loss measurement including static loss and DRFS (Distributed RF Scheme) operation with LLRF (Low Level RF) feedback system, were established successfully. In this talk, the results of the S1-Global cryomodule test are reported, discussed and summarized.
