Abstract
A 6-m cryomodule including four Tesla-like cavities was developed, and was tested in the Superconducting RF Test Facility phase-I at KEK. The performance as a total superconducting cavity system was checked in the cryomodule tests at 2 K with high rf power. One of the four cavities achieved a stable pulsed operation at 32 MV/m, which is higher than the operating accelerating gradient in the ILC. The maximum accelerating gradient (Eacc,max) obtained in the vertical cw tests was maintained or slightly improved in the cryomodule tests operating in a pulse mode. Compensation of the Lorentz force detuning at 31 MV/m was successfully demonstrated by a piezo tuner and predetuning.
