Based on the static electricfield simulation, the structures of diode and insulator, as well as the position and shape of guiding magnetic-field are designed and optimized. Then the experiments of repetition rate and intense current electron-beam diode are carried out on high voltage generator, and the experimental waveforms are brought forth. The compares of the cathode emission character at different vacuum and different cathode materials are presented. The output electron-beam current of graphite and metal cathode are both stable with repetition rate at the candition of p＜0.01Pa. The designed diode can deliver intense electron-beam pulse of 500kV/5kA, pulse width 40ns, repetition rate 100Hz．
