惯性约束中子测温的误差研究

UNCERTAINTY STUDY ABOUT ICF NEUTRONTEMPERATURE MEASUREMENT'S SYSTEMS

综合分析了ICF（惯性约束）中子测温系统的误差与其参数的关系，这些参数包括靶核温度、探测的中子数、靶到探测器的距离、探测器的响应函数以及闪烁作厚度等．考虑到中子与探测器的相互作用、探测器的响应与靶的烧蚀过程，在此基础上提出了新的统计误差计算方法．该方法对于改善中子测温的相对误差并应用于闪烁体的设计具有重要意义．

The relationship between uncertainty of ICF (inertial restrain ) neutron-temperaturemeasurement's system and its parameters are analysed. These parameters including targettemperature, number of detected neutron,distance between target and detector, response function ofdetector and others. Interactions about neutron with detector,response of detector and ablation processare considered. New calculating method of statistical error is raised, which has significance forimproving relative error of measuring neutron-temperature and can be applied to scintillator design.
