G-M计数管能量响应的蒙特卡罗模拟及优化设计

Monte-Carlo Simulation on the Energy Response of GM Counter and Optimum Design

采用蒙特卡罗方法,通过入射粒子在灵敏体积内的能量沉积,模拟计算G-M计数管的探测效率随入射粒子能量的变化关系,得到相应的能量响应曲线;并在此基础上改变包壳材料、厚度、形状等参数,对其设计制作进行优化,从而节省实验测试时间和减小工作量,并使材料组合和形状组合更趋于多样化。

Based on the energy deposition, The energy response of GM counter is simulated by monte - carlo method, and the parameters of the wrapped material, thickness and shape are also varied for having a optimum design ; with these having done, the experiments testing time is saved on, the workload is cut down, the material built- up and shape built -up are also more diversified.
