描述了用于快速闪烁探测器实时并行处理的设计、操作原理和使用 4 通道多重分析仪进行的首次测量的结果。用于检测快中子的有机闪烁介质性能的最新进展，尤其是危险的减少以及最近出现的具有脉冲形状辨别（PSD）的塑料闪烁材料，突出了在基于利用这些介质的探测器的系统中使用多个探测器的可能性。本文描述了一种基于具有集成高压电源和图形用户界面的单板解决方案的实时数字多通道 PSD 分析仪。它的开发是为了满足与保障和安全相关的核材料分析的要求，并在各种相关的实验室环境中进行了测试。
The design, principle of operation and the results of the first measurements made with a 4-channel multiplexed analyzer for real-time parallel processing of fast scintillation detectors is described. Recent advancements in the performance of organic scintillation media for the detection of fast neutrons, not least the reduction in hazard and the recent advent of plastic scintillation materials exhibiting Pulse Shape Discrimination (PSD), has highlighted the possibility of using multiple detectors in systems based on detectors exploiting these media. In this paper a real-time, digital multiple-channel PSD analyzer is described based on a single-board solution with an integrated high-voltage supply and graphical user interface. It has been developed to meet the requirements of nuclear materials assay of relevance to safeguards and security, and tested in a variety of related laboratory-based environments.
