In this study, a diamond-based neutron scatter camera (DNSC) was developed for neutron spectroscopy in high flux environments. The DNSC was evaluated experimentally and through simulations. It was simulated using several Monte Carlo codes in a two-array layout. The two-array model included two diamond detectors. The simulation reconstructed the spectra of 252Cf and 239Pu–Be neutron sources with high accuracy (∼93%). The two-diamond array system was experimentally evaluated, demonstrating the neutron spectroscopy capabilities of the DNSC. The reconstructed spectrum of the 239Pu–Be source manifested the characteristic peaks of the source. The advantage of a DNSC over a NSC is its ability to define any neutron double-scattering events without the need to absorb incident neutrons in the second detector, and atomic recoil energy information is not needed to determine the incident neutron energy.

基于金刚石的中子散射相机

在这项研究中,开发了一种基于金刚石的中子散射相机 (DNSC),用于高通量环境中的中子光谱。DNSC 通过实验和模拟进行了评估。它是使用两个阵列布局中的几个蒙特卡罗代码进行模拟的。双阵列模型包括两个钻石探测器。该模拟以高精度(~93%)重建了252 Cf 和239 Pu-Be 中子源的光谱。对双金刚石阵列系统进行了实验评估,证明了 DNSC 的中子光谱能力。239的重建光谱Pu-Be源表现出源的特征峰。DNSC 优于 NSC 的优势在于它能够定义任何中子双散射事件,而无需在第二个探测器中吸收入射中子,并且不需要原子反冲能量信息来确定入射中子能量。
