  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. The project cost considering main hardware price is the final objective to evaluate the choice of beta family. The C-ADS lianc is used as an example to demonstrate the application of the new method. The optimization process and results are presented in the paper.
