论文摘要
脉冲形状歧视（PSD）对于不扩散和安全应用至关重要，在这种情况下，需要在存在强γ射线背景的情况下识别和测量快速中子。传统的基于电荷整合的PSD方法需要为每个脉冲存储和处理数百个样品，这是高密度通道应用的时间和内存费用。在这项工作中，我们探讨了使用商业ASIC实现PSD的可能性，该商业ASIC允许用户调整脉冲成型时间。我们证明，可以通过最大化脉冲塑形电路对中子和伽马射线脉冲的响应之间的差异来实现PSD。
Pulse shape discrimination (PSD) is crucial for non-proliferation and security applications, where fast neutrons need to be identified and measured in the presence of a strong gamma-ray background. The traditional charge-integration-based PSD method requires the storage and processing of hundreds of samples for every single pulse, which is time- and memory-consuming for high-density channel applications. In this work, we explored the possibility of implementing PSD using a commercial ASIC that allows the user to adjust the pulse shaping time. We demonstrated that PSD can be achieved by maximizing the difference between the pulse shaping circuit's responses to neutron and gamma-ray pulses.
