摘要
用国内近年新研制的CeF3闪烁体和常用闪烁体ST401分别配特性相同的光电倍增管,构成两种闪烁体探测器,在强度不随时间变化的DD中子源场中测量了这两种闪烁探测器的相对灵敏度,测量结果表明:CeF3闪烁探测器对DD中子的灵敏度比同尺寸ST401的灵敏度低一个量级以上。
Two kinds scintillation detectors are composed of cerium fluoride (CeF3) and ST401 with photomultiplier tube respectively, the experimental sample of CeF3 is the newly developed inorganic scintillator in China in recent years, ST401 is a common plastic organic scintillator. The DD neutron relative sensitivity of the two scintillation detectors are measured in DD neutrons source radiation field, which indicate that the DD neutron sensitivity of CeF3 scintillation detector is less than onetenth that of ST401 with same volume.
