用于DPF装置中子测量的闪烁体探测器

Scintillation neutron detector for DPF device

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0．0225pC每中子，中子产额测量范围达到10^9～10^11每脉冲，可以满足DPF装置中子参数测量的需要。

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.
