NE213闪烁体广泛使用于探测快中子,但却伴随很高的g本底。本文使用快信号门与总信号门的两门积分方法,用快信号与总信号进行二维作图来分辨粒子。用252Cf 中子源和d+D核反应产生的单能中子研究了 f5“2”、f5“5”和f8“2”三种尺寸的NE213闪烁体的n-g分辨性能,通过选择合适的门宽,获得了极好的n-g分辨效果。对f5“2”的NE213,最佳快信号门宽为30ns。 摘要 NE213闪烁体广泛使用于探测快中子,但却伴随很高的g本底。本文使用快信号门与总信号门的两门积分方法,用快信号与总信号进行二维作图来分辨粒子。用252Cf 中子源和d+D核反应产生的单能中子研究了 f5“2”、f5“5”和f8“2”三种尺寸的NE213闪烁体的n-g分辨性能,通过选择合适的门宽,获得了极好的n-g分辨效果。对f5“2”的NE213,最佳快信号门宽为30ns。
The NE213 scintillator is widely used to detect fast neutrons but with a high g background. In this paper, two-point integration method of fast signal gate and total signal gate is used to distinguish particles with two-dimensional mapping of fast signal and total signal. We studied the ng resolution performance of NE213 scintillator with three sizes of f5 “2 ”, f5 “5 ” and f8 “2 ” using 252Cf neutron source and d + By choosing the right door width, excellent ng resolution is achieved. For f5 “2 ” NE213, the best fast signal width is 30ns. Abstract The NE213 scintillator is widely used to detect fast neutrons but with a high g background.
