| 摘 要： | 为深入研究具有复杂角分布和能谱分布的系统电磁脉冲(SGEMP)的规律和特性，利用三维全电磁粒子模拟(PIC)程序，并添加相应功能模块——用蒙特卡洛方法实现电子发射的余弦角分布和指数能谱分布。模拟计算光电子由圆柱端面向外发射引起的SGEMP模型，选取2组X射线数据进行计算，并与文献估算结果进行对比。2次计算所得结果量级都与文献结果一致，说明本程序可用于深入研究各种SGEMP问题，为抗核加固和SGEMP效应研究提供基础数据。

| Abstract: | In order to research System-Generated Electromagnetic Pulse(SGEMP) effects which have complicated angular distribution and energy spectra, the 3-D Particle In Cell(PIC) code is used and the function module is appended to it to characterize cosine angular distribution and exponential energy spectra of photoelectrons. The external SGEMP effects induced by photoelectrons emitted from cylinder top surface are simulated by the 3-D PIC code. Two sets of parameters of X ray are adopted for simulation and the results are compared with the data from literature. It is shown that both results are the same in magnitude as that from literature. It is concluded that the PIC code is available for studying SGEMP effects to support basic data for nuclear hardening. |
