摘要: 介绍了一种用于等离子体焦点装置(DPF装置)中子波形测量的塑料闪烁体探测器，该探测器由ST401型塑料闪烁体、XP2262B型光电倍增管构成。利用银活化中子探测器和DPF装置对该塑料闪烁体探测器进行标定，确定其中子灵敏度为0.022 5 pC每中子，，中子产额测量范围达到109～1011每脉冲，可以满足DPF装置中子参数测量的需要。Abstract: In order to research Dense Plasma Focus device (DPF), a kind of scintillation neutron detector is introduced in this paper. The detector consists of a ST401-plastic scintillation and a XP2262B-photoelectric electron-multiplier tube. With a silver activation detector, the DT neutron sensitivity of the scintillation detector is calibrated as 0.022 5 pC per neutron, the neutron yield measurement range is from 109 to 1011 per pulse.
