新型脉冲中子探测器采用特殊工艺将两个PIN半导体组合而成 .利用脉冲γ辐射源研究了探测器对γ的响应 ;利用脉冲中子源研究了探测器对DT中子的响应 ,并与闪烁探测器进行了比较 .结果表明 :脉冲中子探测器对脉冲γ辐射基本不灵敏 ,对脉冲中子辐射的灵敏程度依赖于中子辐射体 ,是一种用于n ,γ混合脉冲辐射场中子测量的新型探测器 The new pulsed neutron detector uses a special process to combine two PIN semiconductors. The response of the detector to γ ​​is studied using a pulsed γ-radiation source. The response of the detector to the DT neutron is studied using a pulsed neutron source, The results show that the pulsed neutron detector is basically insensitive to pulsed γ-radiation and its sensitivity to pulsed neutron radiation depends on neutron radiation. It is a kind of pulsed neutron detector New detector for neutron measurement
