本文概要介绍了超快猝灭塑料闪烁探测器特性，并在不同闪烁体、光导和微通道板光电倍增管的组合条件下用１０ｎｓ脉宽的窄脉冲中子管对探测器的Ｄ－Ｔ中子灵敏度进行了标定。由这些标定数据推算出的探测器不同条件下的Ｄ－Ｔ中子灵敏度与实测数据在误差范围内是一致的。
In this paper, the characteristics of ultra-fast quenching plastic scintillation detector are briefly introduced. In the combination of different scintillator, photoconductors and micro-channel plate photomultiplier tubes, the narrow pulse neutron tube with 10 ns pulse width is used to detect the D-T Sub-sensitivity was calibrated. The D-T neutron sensitivity of the detector under different conditions derived from these calibration data is in agreement with the measured data within the error range.
