Wang, Z.J. JACoW Publishing Geneva, Switzerland The Chinese ADS project now is under key technology R&D and a 25 MeV CW proton superconducting linac is under assembling in Lanzhou by collaboration between IMP in Lanzhou and IHEP in Beijing. The beam commissioning is scheduled in June-July 2017. Before assembling 25 MeV proton linac, IMP team built a 10 MeV proton superconducting linac based on 162.5 MHz HWR cavity technology, which successfully accelerated 9.55-10 MeV@1-2.7 mA CW proton beam in 2016, meanwhile, IHEP team built a 10 MeV proton superconducting linac based on 325 MHz Spoke cavity technology, which successfully accelerated 10 MeV@2.1 mA CW proton beam in 2016. This invited alk will present 1-5 mA CW proton beam commissioning results and lessons learned from the 10-25 MeV superconducting linac.
