本文描述了一个用于中子β衰变角关联精确测量的探测系统。该系统基于与美光半导体公司合作开发的厚、大面积、高度分段的硅探测器。原型系统满足β电子探测的规格，其能量阈值低于10 keV，能量分辨率为1.3 keV FWHM，上升时间为1.50 ns，127个探测器像素中有19个装有仪器。我们在洛斯阿拉莫斯中子科学中心用超冷中子演示了中子β衰变中β粒子和反冲质子的同时探测。全仪器化探测系统将在UCNB和Nab实验中实施，以确定中子β衰变参数B、a和b。
We describe a detection system designed for precise measurements of angular correlations in neutronβdecay. The system is based on thick, large area, highly segmented silicon detectors developed in collaboration with Micron Semiconductor, Ltd. The prototype system meets specifications forβelectron detection with energy thresholds below 10 keV, energy resolution of ∼3 keV FWHM, and rise time of ∼50 ns with 19 of the 127 detector pixels instrumented. Using ultracold neutrons at the Los Alamos Neutron Science Center, we have demonstrated the coincident detection ofβparticles and recoil protons from neutronβdecay. The fully instrumented detection system will be implemented in the UCNB and Nab experiments to determine the neutronβdecay parametersB,a, andb.
