四探头井型快中子符合测量实验装置(图1)主要由4个φ127mm×50.8mm的BC501A液体闪烁探测器、DC271A四通道超高速数据采集卡及相关电路等构成,将主要应用于铀钚材料质量测量研究。4个BC501A探测器的阳极负脉冲信号分别经恒比定时器甄别后再经混合电路混合作为DC271A的触发信号,打拿极正脉冲信号则直接送入DC271A。基于LabWindows平台开发的应用
The four-probe well-type fast neutron coincidence measurement experiment device (Figure 1) is mainly composed of four φ501mm × 50.8mm BC501A liquid scintillation detectors, a DC271A four-channel ultra-high speed data acquisition card and related circuits, and will be mainly applied to uranium and plutonium Material Quality Measurement Research. 4 BC501A detector anode negative pulse signal respectively, after the constant ratio timer discriminated by the hybrid circuit mixed DC271A trigger signal, take a positive pulse signal is sent directly to the DC271A.
