Challenges and Performance of the C-ADS Injector System

Along with the rapid development of nuclear power plants in China, treatment of the nuclear waste has become a crucial issue. Supported by the "Strategic Priority Research Program" of the Chinese Academy of Sciences (CAS), The Chinese ADS project is now on-going based on the collaboration of several Chinese institutions. In the end of year 2015, China Initiative ADS (CIADS) program is approved by Chinese government, will construct in the Guangdong province south part of China. The proton accelerator of Chinese ADS is a superconducting CW linear accelerator. Its energy is 1.5GeV, with beam current of 10mA. Institute of High Energy Physics (IHEP) and Institute of Modern Physics (IMP) are responsible to developing this superconducting CW linear accelerator. In the injector part there are many challenges to developing several different low beta superconducting cavities and related hardware’s such like LLRF system etc. In this paper presents the progress of two different injector development including SC cavities and related hardware’s and performance test of two injectors and key hardware’s, and also brief introduction of CIADS program.
