我们在神光装置打靶现场对加门光电倍增管进行了调试和研究。实验结果表明，光电倍增管的恢复时间是随其饱和深度的增加而增加的。ＸＰ２０４０光电倍增管配上２μｓ的高压脉冲开关可用于液体闪烁探测器在神光装置辐射驱动聚变靶时进行强Ｘ射线辐射场的低产额中子测量。 We Shenjiaguang device targeting the scene of the Galvanic photomultiplier tube debugging and research. Experimental results show that the photomultiplier tube recovery time increases with the increase of its saturation depth. XP2040 Photomultiplier Tube Coupled with 2μs High Voltage Pulse Switch for Liquid Scintillation Detector Low-yield neutron measurement of intense X-ray field when Shenzhou unit radiates fusion target.
