Monte Carlo模拟电子在球壳模型中的能量沉积分布

Monte-Carlo Simulation of Energy Deposition of Electrons in a Spherical Shell Model

高能电子和物质相互作用是一个级联簇射 (shower)物理过程 .空间飞行器防护系统就是利用这一原理 ,通过宇宙中的电子在飞行器中产生的 shower电子 ,来了解其中半导体器件的有关信息 .该文利用 Monte Carlo方法 ,采用 PENEL OPE(Penetration and Energy L oss of Positrons and Electrons)软件包 ,对电子在飞行器中的运动过程进行模拟 ,给出球壳和半导体材料中的能量沉积分布 。

An electron with high energy produces a shower of particles when striking a target. The safeguard system of spatial aircraft provides the semiconductor devices information through detection of the shower particles produced by the electron beam. The energy deposition in spherical shell and semiconductor material is calculated with PENELOPE Monte Carlo program. The results are useful in safeguard of spatial aircraft.
