The DC-SC photoinjector at Peking University is designed to provide an electron beam of average current 1mA with the energy of 2~3MeV and normalized rms transverse emittance of 3πmm-mrad at an 81.25MHz repetition rate. The test facility has been completely installed in our lab. In this paper some of the ongoing experimental activities are summarized. First results from the cold test of superconducting cavity have been presented. According the results, we have improved the main coupler to repress the multipacting. The beam test of 100μA on the DC gun has been done, photocathode preparation chamber can produce Cs2Te cathodes (5%@266nm), and the laser system can provide laser pulse with 266nm wavelength. The time synchronization between laser and RF power has been achieved by a timing stabi
