The 10 MeV accelerator-driven subcritical system (ADS) Injector I test stand at Institute of High Energy Physics (IHEP) is a testing facility dedicated to demonstrate one of the two injector design schemes [Injector Scheme-I, which works at 325 MHz], for the ADS project in China. The ion source was installed since April of 2014, periods of commissioning are regularly scheduled between installation phases of the rest of the injector. Early this year, continuous wave (CW) proton beam has been successfully obtained with energy of 10MeV and average beam current around 2 mA, the single spoke cavities with smallest developed beta (βg=0.12) were applied and successfully commissioned. Single spoke cavities with higher beta (βg=0.21) were also adopted for the last cryomodule of 25MeV proton linac, and 170uA CW proton beam were shooting through recently. This contribution reports the details of the development of the C-ADS SRF accelerator at IHEP and the challenges of the CW machine commissioning

The recent SRF R&D efforts on TEM-type cavities at IHEP have been strongly linked to two large projects: high current proton linac for ADS and High Energy Photon Source (HEPS). A CW 10 MeV proton injector and part of the 25 MeV main linac for the CADS project are developed at IHEP. 14 SRF spoke012 cavities for the injector have been commissioned with 10.6mA proton beam at 10.67MeV; while 6 SRF spoke021 cavities for the main linac have been assembled into cryomodule in Lanzhou. 166.6 MHz quarter-wave β=1 cavities were proposed for HEPS storage ring, required by the planned on-axis beam accumulation injection scheme. Each 166.6 MHz cavity will be operated at 4 K providing 1.2 MV accelerating voltage and 145 kW of power to the electron beam. A proof-of-principle cavity has been manufactured and vertical tested recently with a success. HOM damping is currently being designed. The development progress of the 6 types of spoke, HWR, QWR cavities, and their ancillaries, as well as the spoke cavity performance during beam operation, will be addressed.
