摘　　要：本文研究开发直线感应加速器的光发射模块,并验证该模块的正确性.首先建立光发射模型,该模型确立阴极参数和入射激光与宏粒子初始值间的关系,并将该模型实现到代码中;其次,根据实验参数建立注入器模型,模拟光阴极的发射过程;最后,将模拟结果与实验结果比较,发现模拟的发射电流与实验电流吻合,发射度与理论分析一致,验证了模拟的正确性.We study photocathode of linear induction accelerator. A photoemission model was implemented which takes into account details such as photocathode material and laser source. A relationship between photocathode and macro particle initial condition is established. We achieved this model in LIAPIC code. A photocathode injector model was set up to simulate photoemission. At last,the model is verified. Simulation results are concordant with experiment.
