我们报告的脉冲形状歧视（PSD）的性能，由Eljen公司和Amcrys制造的塑料振荡器。在这项研究中，我们调查的快中子和伽马性能的塑料闪烁器时，耦合到SensL J系列硅光电倍增管（SiPM）和读出的快速波形数字化器的ADC分辨率为14位和采样率为500 MS/s。调查发现，与之前的C系列相比，SensL J系列SiPM的PSD性能显著提高，两家供应商的最新塑料闪烁体也是如此。使用同步电荷积分脉冲形状鉴别（PSD）算法进行分析，该算法应用于从AmBe中子源的混合快中子/伽马辐射场获得的数据。离线处理收集的脉冲，计算能量和PSD参数。PSD性能的质量由共同的品质因数（FoM）表征。最佳的n-γ分离是由较新的Eljen EJ-276闪烁体发现的，在1.5 MeV伽马当量的能量下，FoM值为3.03±0.03。Amcrys UPS-113 NG材料的FoM值为2.60±0.04。
We report on the pulse shape discrimination (PSD) performance of plastic scintillators manufactured by Eljen Corporation and Amcrys. In this study we investigate the fast neutron and gamma performance of the plastic scintillators when coupled to the SensL J-series silicon photomultiplier (SiPM) and read out with fast waveform digitisers with an ADC resolution of 14-bits and a sample rate of 500 MS/s. The investigation observes a significant PSD performance increase for the SensL J-series SiPM in comparison to the previous C-series, and also for the latest variants of plastic scintillator from both suppliers. Analysis was performed using a Synchronous Charge Integration Pulse Shape Discrimination (PSD) algorithm which was applied to data acquired from a mixed fast neutron/gamma radiation field from an AmBe neutron source. The collected pulses were processed offline with the energy and PSD parameters calculated. The quality of the PSD performance was characterised by a common figure of merit (FoM). The best n-γ separation was found by the newer Eljen EJ-276 scintillator with a FoM value of 3.03±0.03 at an energy of 1.5 MeV gamma equivalent. The Amcrys UPS-113NG material achieved a FoM value of 2.60±0.04.
