Cryomodule Tests of Tesla-like Cavities in S1-Global for ILC

S1-Global project for ILC is an international collaboration for cryomodule tests including eight 9-cell sc cavities from DESY, FNAL and KEK. One of two 6-m cryomodules, Cryomodule-A, contains four Tesla-like cavities with slide-jack tuners and STF-II couplers. The cryomodule was assembled and was installed in the STF tunnel. The first cool-down tests and low power rf tests were carried out in June-July, 2010.
