Abstract

We present a multi-channel, fast-neutron/photon detection system that uses ZnS(Ag) scintillator detectors. The system employs field-programmable gate arrays to pulse-shape analysis for real-time all-digital neutron/photon differentiation, producing particle-dependent pulse height and temporal distributions while allowing count rates in excess of 1,000,000 events per second per channel. The system size is scalable in blocks of 16 channels.
快中子闪烁体在瞬态反应堆试验装置(TREAT)反射镜中实时脉冲形状识别的优化
我们提出了一种使用ZnS(Ag)闪烁体探测器的多通道快中子/光子探测系统。该系统采用现场可编程门阵列进行脉冲形状分析,用于实时全数字中子/光子分化,产生与粒子相关的脉冲高度和时间分布,同时允许每个通道每秒超过1,000,000个事件的计数率。系统大小可扩展为16个通道的块。
