硅光伏探测器探测α粒子研究

摘要

采用蒙特卡罗方法计算了硅光伏探测器探测α粒子的能量分辨率等参数,通过实验测得了其α谱和探测效率.实验表明,硅光伏探测器对α粒子具有较高的探测效率和能量分辨率,受β、γ射线影响小,非常适合用作α粒子探测器.%Monte Carlo method was used to simulate the energy resolution of silicon photovoltaic detector for a -particle. The experiments showed that silicon photovoltaic detector had high energy resolution and detection efficiency. The influence of α- ray and α - ray was avoidable, so silicon photovoltaic detector was available to detecting α- particle.
