摘要: 为提供探测器或样品辐照实验与靶物质选择所需的辐射环境基本物理参数,利用蒙特卡罗模拟软件FLUKA对BEPCⅡ-LINAC试验束E2线上的第二靶室混合辐射环境进行了模拟计算,得到了以靶心为圆心,半径为1 m的球面上的各次级粒子的微分通量、角度微分截面、磁谱仪方位角上的双微分能谱、靶室内的剂量率分布。Abstract: In order to get basic physical parameters of radiation environment for detector or sample irradiation experiment and optimal target material choice, Monte Carlo simulation software FLUKA is used to calculate parameters of mixed radiation environment in target chamber Ⅱ on E2 line of test beam. At last, physical parameters: secondary particles differential fluencies, secondary particles angular differential cross-section, dual differential energy spectrum, dose rate distribution are acquired.
