An electron gun for X-band relativistic backward wave oscillator was presented in this paper. An electromagnetic particle-in-cell code is being used to investigate this device. The simulation results show that this device can generate 4 kA, 550 kV electron beams, has the characteristics such as long-life employ, high vacuum ratio and good performance, and can get high repetition frequency output. It can gain 1.5 GW peak power microwave at 10.34 GHz, the power efficiency is about 20%.
