摘要

本文介绍了基于 CLYC 晶体开发的用于环境辐射监测的便携式中子-伽马探测器。它可以用作伽马能谱仪、伽马剂量计和热中子计数器。通过在 CLYC 晶体和 PMT 中使用拟议的电流模式，伽马剂量率的测量上限约为 6 mSv/h。同时，该探测器在 662 keV 时的伽马能量分辨率为 4.86%，伽马和中子脉冲形状判别优度（FOM）为 3.32 ± 0.04。在应用的最初阶段，该探测器被用于测量中国溅射中子源（CSNS）相关质子束实验平台（APEP）束线和R-dump室周围的伽马和中子辐射水平。

Development of a CLYC-based wide dose rate range portable neutron-gamma detector

This paper describes the development of a portable neutron-gamma detector for environmental radiation monitoring based on the CLYC crystal. It can function as a gamma spectrometer, gamma dosimeter, and thermal neutron counter. The upper measurement limit of gamma dose rate is approximately 6

mSv / h

by using the proposed current mode in CLYC crystal and PMT. Meanwhile, the detector has a gamma energy resolution of 4.86% at 662 keV, and a figure of merit (FOM) of 3.32 ± 0.04 for gamma and neutron pulse shape discrimination. In the initial phase of applications, the detector was used to measure the gamma and neutron radiation levels around the beamline of the associated Proton beam Experiment Platform (APEP) and R-dump room at the China Spallation Neutron Source (CSNS).

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
