	A 10 MeV superconducting proton linac is being design and constructing at Institute of Modern Physics (IMP) of Chinese Academy of Sciences (CAS). This proton linac is one of two injectors for Chinese ADS project. It is to validate one of concepts for C-ADS front end, to demonstrate the low beta acceleration, to minimize the risk of key technoledges within the Reference Design. It consists of a 2.1 MeV RFQ and two cryomodules hosting 8 HWR cavities. The basic frequecy is 162.5 MHz. The physical design of linac and the progess of prototypes for solid state amplifiers, superconducting solenoids, supercondecting HWRs, ion source, and RFQ are presented in the paper.

	A four-vane RFQ accelerator has been designed for the ADS project which has been launched in China since 2011. As one of the front ends of C-ADS LINAC, the RFQ works at a frequency of 162.5 MHz, accelerating the proton beam from 35 keV to 2.1 MeV. Due to the CW (continuous wave) operating mode, a small Kilpatric factor of 1.2 was adopted. At the same time, Pi-mode rods are employed to reduce the effect of dipole mode on quadrupole mode, and cavity tuning will be implemented by temperature adjustment of cooling water. Beam dynamics design, RF cavity design, thermal and stress analysis all will be presented in the paper.
