Abstract：
The beam dynamics in micro-pulse electron guns (MPG) is studied using simulation methods in this paper. Based on the working principle of MPGs and the characteristics of its beam dynamics, a multi-particle trace simulation about the three-dimensional movement of the electrons in a MPG cavity is given by a program SEEG (Secondary Electron Emission Gun) written in VC++. The paper includes the principles of simulation and the stability tests of the program SEEG. A specific MPG is simulated using the program SEEG and the simulated beam dynamic results are given.
