| 摘 要： | 塑料闪烁探测器通常用来测量氘氘、氘氚聚变中子产额。中子在闪烁体中产生的质子数的统计涨落及质子在闪烁体中沉积能量的统计涨落为测量结果引入了两项不确定度分量。以氘氚聚变中子为例，分析了这两种统计涨落的概率密度函数的计算方法，该计算方法也适用于其它能量的单能快中子和塑料闪烁体作用的相应计算。

| Abstract: | The plastic scintillation detector is used to measure the yield of DD neutrons or DT neutrons.Fast neutrons incident on the scintillator give rise to recoil protons.Because the range of the recoil protons is usually small compared with the dimensions of the scintillator,their full energy is deposited in the scintillator.The statistic fluctuation of the protons' number and that of the protons' total energy are two sources of the measurement uncertainty.Based on DT neutrons,this paper presents the algorithms ... |
