摘要

通过开发三维PIC代码，并在代码中编译MC功能模块，实现了从x射线到电磁场环境的整个SGEMP三维仿真，将传输代码JMCT计算的任意能量、角度、空间和时间分布的光电子直接转化为PIC仿真中使用的初始电流源。对仿真结果进行了初步分析。当温度为1 keV，发射能量为1 J/cm2的黑体x射线垂直照射高度为2.0 cm，半径为1.0 cm，材料为Al的圆柱形物体的侧面时，发射电流为0.11 A，电场可达100 kV/m，磁场大于1.6×10−6 T。

Simulation of cylinder SGEMP radiated by X-ray

The whole 3D simulation of SGEMP from X-ray to electromagnetic field environment is realized by developing 3D PIC code with compiling MC function modules in it, so that photoelectrons of arbitrary energy, angular, spatial and time distributions which calculated by transport code JMCT could be transformed into the initial current source used in PIC simulation directly. The simulation results are analyzed preliminarily. It is obtained that the emitted current is 0.11 A while the electric field could get 100 kV/m and magnetic field is over 1.6×10−6 T when the blackbody X-ray of temperature 1 keV and emitted fluence 1 J/cm2 perpendicularly irradiates the side of cylindrical object with material of Al and height of 2.0 cm, radius of 1.0 cm.
