文章着眼于提高地球同步轨道(GEO)空间地磁亚暴带电效应模拟的真实度,对多能量电子模拟空间地磁亚暴带电的方法进行分析评估。首先采用单一能量电子束的地面试验对SENSIT工程软件进行了校准；然后参考地磁亚暴环境能谱,用该软件对Kapton样品在单一电子束、双电子束、全能谱电子辐照下的充放电特性进行了计算预示。研究表明：表面充电速率受控于电流密度；在12．5keV/32．5keV电子束组合时其效应模拟的结果最有代表性；在双电子束模拟中,较高能量电子源起关键作用。
This paper analyzes and evaluates the method of multi-energy electron simulation of the geomagnetic sub-stratospheric electromagnetism by focusing on the simulation of the geomagnetic sub-stratospheric effects in the geosynchronous orbit (GEO) space. Firstly, SENSIT engineering software was calibrated by ground test of single energy electron beam. Then referring to the spectrum of geomagnetic sub-storms environment, the software was used to charge and discharge Kapton samples under single electron beam, double electron beam, Characteristics were calculated and predicted. The results show that the surface charge rate is controlled by the current density, and the simulation results are the most representative when the 12.5keV / 32.5keV electron beam is combined. In the dual electron beam simulation, the higher energy electron source plays a key role.
