Abstract：
Modeling multipacting to steady state saturation is of interest in determining the performance of the micro-pulse electron gun. In this paper,a novel method is proposed to calculate the multipacting resonance parameters for the gun. This method works well,and the 2-D simulation results suggest that steady state saturation can be achieved in the gun. After saturation the transition from two-surface multipacting to single-surface multipacting occurred,and an extensive range of electron emission time is a suggested way to avoid this kind of transition.
