The use of laser-driven light and 100kV DC acceleration gap can produce a width of 50 ~ 100ps high brightness pulsed electron beam. The device is mainly composed of photocathode preparation room and DC acceleration gap. The photocathode can be prepared by chemical vapor deposition, ion implantation and ion beam enhanced deposition. Through the simulation with EGUN and POISSON programs, the physical design of DC acceleration gap is given. The light source uses a main passive double-locked Nd: YAG laser, which can work at three wavelengths of 1064, 532 and 266nm with a repetition frequency of 10Hz. In addition, the relevant issues of the superconducting high brightness injector combined with the ultra-cavity with the photo-cathode preparation chamber
