摘要： 本工作报告了使用熔融沉积建模（FDM）增材制造技术制造的新型中子敏感闪烁探测器的性能。 FDM是一种成本效益高的3D打印方法，采用柔性塑料丝材来制造定制形状的部件。 基于聚苯乙烯掺杂\emph{p}-联苯和1,4-双(5-苯基恶唑-2-基)苯的闪烁丝材，并富含$^6$LiF以实现中子灵敏度，在本实验室制造并实现了可见闪烁，光输出为30$\pm$5~每MeV光子。 然后将打印的闪烁体集成到包含图像增强型TimePix3相机的探测器系统中，提供了高空间和时间分辨率。 探测器性能与Geant4对闪烁传感器在电子、伽马射线和热中子作用下的响应的模拟进行了比较。 一种新颖的事件鉴别算法，利用TimePix3相机的特性，实现了中子特征与伽马射线背景的分离。 显示英文摘要

摘要： This work reports on the performance of a novel neutron-sensitive scintillating detector fabricated using Fused-Deposition Modelling (FDM) additive manufacturing. FDM is a cost-effective 3D-printing method employing flexible plastic filaments to create custom-shaped components. Scintillating filaments, based on polystyrene doped with \emph{p}-terphenyl and 1,4-bis (5-phenyloxazol-2-yl) benzene, and enriched with $^6$LiF to enable neutron sensitivity were manufactured in house and achieved visible scintillation with a light output of 30$\pm$5~photons per MeV. Printed scintillators were then integrated into a detector system consisting of an image intensified TimePix3 camera, offering high spatial and temporal resolution. The detector performance was compared with Geant4 simulations of the scintillating sensor's response to electrons, gamma-rays, and thermal neutrons. A novel event discrimination algorithm, using the properties of the TimePix3 camera, enabled the separation of neutron signatures from the gamma-ray background.
