This article presents a model setup of neutron sensors consisting of a Li-glass scintillator coupled with a silicon photomultiplier (SiPM) array. The newest developments based on SiPMs array enable high-gain and the low-light detection capabilities of the traditional photomultiplier tube (PMT) while offering the benefits of a solid-state sensor: low-voltage operation, insensitivity to magnetic fields, reduced dimensions, and mechanical robustness. Measurements conducted with the presented setup were complemented with the Monte Carlo N-Particle Transport Code (MCNP) numerical simulations for larger systems. The results indicate the feasibility of utilizing the presented technology for highly sensitive handheld neutron radiation detectors in compliance with the requirements of IEC 62534 standards.

基于锂玻璃闪烁体和 SiPM 阵列的中子检测模块

本文介绍了一个中子传感器的模型设置，它由一个锂玻璃闪烁体和一个硅光电倍增管 (SiPM) 阵列组成。基于 SiPMs 阵列的最新发展实现了传统光电倍增管 (PMT) 的高增益和低光检测能力，同时提供了固态传感器的优点：低电压操作、对磁场不敏感、尺寸减小、和机械强度。使用所提出的设置进行的测量得到了更大系统的蒙特卡罗 N 粒子传输代码 (MCNP) 数值模拟的补充。结果表明，将所提出的技术用于符合 IEC 62534 标准要求的高灵敏度手持式中子辐射探测器是可行的。
