Times Cited Count：0 Percentile：0(Physics, Applied)A prototype cryomodule containing two 9-cell superconducting cavities of 
=0.725 and 
=972 MHz had been constructed under the collaboration of Japan Atomic Energy Research Institute (JAERI) and High Energy Accelerator Research Organization (KEK) on the development of superconducting LINAC for Accelerator Driven System (ADS). Cool-down tests to 2 K of the cryomodule and high power rf tests with a 972 MHz pulsed klystron have been carried out. Rf power of 350 kW in pulsed operation of 3 msec and 25 Hz was transferred to a nine-cell cavity through an input coupler. Accelerating gradients of 14 MV/m (compared to the specification of 10 MV/m) have been achieved in both cavities. Compensation of Lorentz-force detuning by a piezo tuner was successfully demonstrated.
