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.

Abstract: 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.

Key words: linear induction accelerator, photocathode, quantum efficiency, injector, particle in cell
