The experimental system of the photo-cathode superconducting accelerator consists of a quadruple-frequency Nd: YAG mode-locked laser, a Cs2Te photocathode, a 2 +1 / 2 microwave electron gun, a L-band 3.5 MW pulsed microwave source, a 1.3 GHz single cavity superconducting niobium Cavity, a 500 W continuous microwave source, a superconducting cavity tube coupler, a 4.2 K cryostat, a liquid helium refrigeration system, a synchronous control system, a beam parameter diagnosis, a vacuum system and the like. The principle experiment of photocathode superconducting accelerator was carried out. The energy gain of the superconducting accelerating section was found to be 0.58 MeV and the micro pulsed beam intensity was 0.1 A
