Abstract：
Power couplers, used in China-ADS proton linac injector Ⅰ, are required to transfer 6 kW RF power to the superconducting Spoke cavities. At present, first the two couplers of a coaxial design have been fabricated, which accomplished a high power test at IHEP. The test results indicated that couplers of this design are qualified to deliver 10 kW RF power in continuous travelling wave mode. This paper describes the coupler's room temperature test procedures and results and discusses the original high power test, which was terminated due to serious out-gassing and after some modifications. In the final test, the couplers smoothly exceeded the design power level.
