	Experimental study on superconducting electron linac has been developed at Peking University. Stable operation of a DC-SRF photoinjector and a 2*9-cell SRF linac has been realized with an average beam current of mA scale in macro pulses of several ms with a repetition rate of 10 Hz. A compact high repetition rate THz radiation source has been developed based on DC-SRF photo-injector through velocity bunching. Superradiant THz radiation with a repetition rate of 16.25 MHz and a frequency that can be tuned from 0.24 to 0.42 THz was generated by varying the electron beam energy from 2.4 to 3.1 MeV. MeV UED at MHz repetition rate has been demonstrated experimentally using electron pulses from the DC-SRF photoinjector. THz undulator radiation of ~1THz central frequency with an average power of 1W has been achieved with 13MeV electron beam from SRF linac and applications are underway.

	A 2×4-cell superconducting linac module for the THz-FEL facility has been developed at the China Academy of Engineering Physics, which is expected to provide 6~8 MeV quasi-CW electron beams with an average current of 1~5 mA. The module consists of two 4-cell cavities, two power couplers, two tuners and the cyromodule. The main components are tested before the module assembly. The cavity test includes microwave measurement at room temperature and vertical test at 2 K. The conditioning and test of the couplers are also finished. The performances of the main components and the whole module are present-ed in this paper. The horizontal test indicated that the effective field gradients of both cavities have reached 10 MV/m, which have satisfied our designed goal.

The cavity test includes microwave measurement at room temperature and vertical test at 2 K. The conditioning and test of the couplers are also finished. The performances of the main components and the whole module are present-ed in this paper.
