Abstract：
a tracking algorithm using grid–based space charge fields is studied for the analysis of secondary emission microwave electron gun(semeg). the poisson equations of the space charge forces are determined in the bunchs rest frame with a multi–grid method. the particles equations of motion are solved with a fifth–order embedded runge–Kutta method. the results of the semeg by this algorithm are presented and compared with these by mafia algorithm.
