  C-ADS linac is under key technology development stage. At present it focuses on the construction of two injectors with proton energy 10 MeV. One injector goes to 325 MHz RFQ and Spoke cavity technology being developed by IHEP in Beijing. The other injector consists of 162.5 MHz  RFQ and HWR cavity being developed by IMP in Lanzhou.  The construction of the high current ECR proton source, the CW RFQ accelerator, superconducting HWR and spoke cavities have made a great progress. It is expected to start 5 MeV CW proton beam commissioning by the end of 2014 for the both injectors in terms of  current status. This paper presents the status of the R & D activities for the C-ADS linac.

A new-concept injector for heavy ion synchrotrons, combined with a laser ion source, a Hybrid Single accelerator Chamber (HSC), has being developed based on Direct Plasma Inject Scheme (DPIS) at Institute of Modern Physics (IMP). The HSC is a linac integrating RFQ and DTL into a single chamber while costing partial matching efficiency between and the RFQ and DTL. Nevertheless, due to the capability of the laser ion source in producing intensive ion pulse and the advantage of DPIS, the intensity of the accelerated ion beam was still quite impressive. With this new-concept injector, C6+ ion beams could be accelerated to 2 MeV/u in less than 3 meters, which provides a possibility to use the most efficient single turn injection mode for filling of the synchrotrons rings. The preliminary results on the injector will be presented in this paper. And the investigation on the matching between the LIS and HSC, and that between RFQ and DTL part is still ongoing.
