摘要
聚变反应随时间变化诊断装置是惯性约束聚变(ICF)研究中的一项重要诊断设备,使用蒙特卡罗程序Geant4研究了基于气体切伦科夫探测器的聚变反应随时间变化诊断装置的时间分辨和辐射转换效率，给出了优化后的辐射转换体材料厚度，以及CO2气室压力与长度。模拟计算表明，优化后的系统时间分辨可达22 ps左右，伽马-切伦科夫光子转换效率可达4.7×10-3 Cherenkov photons/gamma。
Abstract
The fusion reaction history is valuable information for inertial confinement fusion experiment research. The Geant4 toolkit was used to study the system performance of the fusion reaction history diagnostic facility based on gas Cherenkov detector. The material and thickness of the radiation converter were optimized along with the pressure and length of the CO2 gas cavity. Simulation results indicate that the system time resolution and conversion efficiency reach about 22 ps and 4.7×10-3 Cherenkov photons/gamma respectively after optimization.
