闪烁探测器中子相对光输出曲线标定技术

The technique of calibrating relative photo-output curve of scintillator detector

叙述了利用多道分析仪标定闪烁探测器光输出曲线的原理,用挡锥法消除了大厅散射中子和γ本底的影响,通过空靶(不含D和T)实验消除了靶头产生的γ的影响。实现了闪烁探测器中子光输出曲线的标定。

A method for calibrating photo-output curve of scintillator detector with multi-channel analyzer is introduced. The neutrons and γ rays scattered from wails were filtered with the tapered shield. The influence of γ rays from target was cleared through the experiments in which the target didn＇t include D and T. The calibration of photo-output curve of scintillator detector has been accomplished.
