摘要: 为在神光系列激光装置上开展惯性约束聚变（ICF）带电粒子诊断，通过0.7～10 MeV加速器质子源和²⁴¹Am放射性同位素α粒子源完成了CR39探测器的质子和α粒子能量响应实验研究，结合TRIM程序和半经验模型建立了CR39刻蚀动力学模拟程序，模拟分析了p、D、T和α粒子在正入射和斜入射条件下CR39的径迹形状与能量响应特征，对多种ICF带电粒子谱仪的CR39探测器单元的设计提出了优化方案。

Abstract: For the application in the charged particle diagnostics on the SG serial laser facilities, the energy responses of CR39 detector with 0.7-10 MeV protons and α particle were investigated by the accelerator proton source and ²⁴¹Am radioactive isotope source, respectively. An etching kinetic simulation code was developed based on the TRIM code and semi-empirical model. The characterizations of the energy responses and track shapes of p, D, T and α particles were simulated under the perpendicular incident and oblique incident conditions. Some schemes were proposed to optimize the CR39 detector unit for some application in ICF charged particle spectrometers.
