	Z.J. Wang, Y. He, H. Jia, S.H. Liu IMP/CAS, Lanzhou, People's Republic of China
	China ADS project is lunched in 2011 by CAS (Chinese Academy Science), which aims to solve the nuclear waste disposition problem. The Injector as a demonstrated facility composed by RFQ cavity, superconducting cavities has been installed on-line and commissioned from June 2014. Proton beam has been accelerated to 5 MeV at CW operation mode successfully. More than 25kW proton beam has been operated stable for one hour, which is the highest record among the same type linacs. In this paper, the commissioning issues and results for high beam power superconducting linac will be presented in detail.

	*High power superconducting linac develops fast recently with the strong demand from research and application. The cost and scale of the projects increase with the energy and beam power. For the superconducting linac, the choice of beta family is the key point to determine the effective acceleration efficiency of the whole facility. The Particle swarm optimization algorithm (PSO) is proposed to optimize the TTF value of the cavities to increase the acceleration efficiency.

	*In order to avoid the hybrid ions like H²⁺, H³⁺ injecting into the RFQ and the residual gas H2 tracing through the RFQ which may lead the RFQ cavity performance degradation, we present the conceptual design of the Low Energy Beam Transport (LEBT) for the China Accelerator Driven Sub-Critical reactor system (C-ADS) accelerator. The LEBT, consisting of one bending magnet and three solenoids and four short-drift sections, match the CW proton beam with 35KeV and 10mA to the entrance of a radio frequency quadrupole (RFQ). This bending LEBT can easily separate the unwanted ions. With the edge angles and one quadrupole to correct the beam asymmetry causing by the bending magnet, the simulation results meet the RFQ entrance requirements.
