强流电子束在薄靶中能量沉积的模拟计算

SIMULATED CALCULATION OF ENERGY DEPOSITION OF RELATIVISTIC ELECTRON BEAM IN THE THIN TARGET

一、引言美、日等国发表过利用强流相对论电子束打靶的实验与理论工作。本文采用MonteCarlo方法模拟计算强流电子束在薄靶物质中的能量沉积。目的是配合中国原子能科学研究院17室强流电子束加速器的物理实验,提供一些理论解释。

The Monte Carlo calculations of the energy deposition of relativistic electronbeam (REB) in 50μm Al, 20μm Cu and 7μm Au thin targets and the angulardistributions of the outgoing electrons are described in the cases of differentincident distributions and taking into account the diode electric field effects andthe values of the deposited energies in 25 subregions for each target aregiven.
