利用数字电子学系统的波形,发展了一种脉冲形状鉴别(PSD)的离线分析技术,以改善NE-213闪烁体中的中子-γ分离,该闪烁体两端与光电倍增管(PMT)耦合。新的改进方法称为“赋值PSD”(VPSD),为每个波形分配一个归一化的拟合残差作为PSD值。然后,该过程便于并入闪烁体的纵向位置依赖性,这进一步增强了探测器系统的PSD能力。在这篇文章中,我们使用从AmBe中子源发出的辐射来证明,所得到的中子-伽马识别相比,传统的技术,使用的几何平均值(GM)的光输出从两个光电倍增管的已大大改善。新方法也被修改并应用于国家超导回旋加速器实验室(NSCL)最近的一项实验,该实验使用模拟电子系统。
Using the waveforms from a digital electronic system, an offline analysis technique on pulse shape discrimination (PSD) has been developed to improve the neutron-gamma separation in a bar-shaped NE-213 scintillator that couples to a photomultiplier tube (PMT) at each end. The new improved method, called the “valued-assigned PSD” (VPSD), assigns a normalized fitting residual to every waveform as the PSD value. This procedure then facilitates the incorporation of longitudinal position dependence of the scintillator, which further enhances the PSD capability of the detector system. In this article, we use radiation emitted from an AmBe neutron source to demonstrate that the resulting neutron-gamma identification has been much improved when compared to the traditional technique that uses the geometric mean (GM) of light outputs from both PMTs. The new method has also been modified and applied to a recent experiment at the National Superconducting Cyclotron Laboratory (NSCL) that uses an analog electronic system.
