阐述通过COMSOL和Genat4联合仿真的方式,对电子感应加速器加速场进行仿真,模拟出电子在加速腔中的运动轨迹。根据7.5MeV小型电子感应加速器实验平台设置仿真参数,仿真出电子能量为7.62MeV,与实际测量电子能量7.28MeV相对误差为4.7%,仿真结果与实际相符。

This paper expounds the simulation of the acceleration field of an electron induction accelerator through the joint simulation of COMSOL and Genat4,simulating the motion trajectory of electrons in the acceleration chamber.According to the simulation parameters set on the 7.5MeV small electron induction accelerator experimental platform,the simulated electron energy was 7.62MeV,with a relative error of 4.7%compared to the actual measured electron energy of 7.28MeV.The simulation results are consistent with the actual measurement.
