摘要

本文介绍了利用单晶化学气相沉积（CVD）金刚石探测器评估快中子能谱的方法，该方法适用于通常具有混合和高剂量辐射场特征的先进科学/工程系统的辐射监测。基于脉冲形状和宽度的脉冲形状判别（PSD）被用于提取快中子击中单晶金刚石特定深度的事件。对提取脉冲的测量频谱进行展开，可以推断出中子能谱。使用单能中子源进行的实验证明，这种方法具有定量评估中子能谱的可靠能力。

Application of a Single-Crystal CVD Diamond Detector for Fast Neutron Measurement in High Dose and Mixed Radiation Fields

This article presents the method to evaluate the fast neutron energy spectrum using the single-crystal chemical vapor deposition (CVD) diamond detector to be applicable on the radiation monitoring in advanced scientific/engineering systems usually characterized with mixed and high-dose radiation field. The pulse shape discrimination (PSD) based on the shape and the width of a pulse was applied to extract events, in which fast neutron hits at the specific depth of the single-crystal diamond. Unfolding of the measured spectrum for extracted pulses could deduce the neutron energy spectrum. Experiments using monoenergetic neutron sources demonstrated the reliable capability of this method to evaluate the neutron energy spectrum quantitatively.
