AI 中文摘要
有机闪烁体已被使用数十年，以低成本探测伽马射线或快中子。尽管已开展大量研究，仍难以在单一闪烁体材料中同时兼顾稳定性、坚固性、高光产额和良好的脉冲形状甄别（PSD）性能。我们采用了一种非常规方法，将磷光体和波长移位剂嵌入固体聚氨酯基质中，试图将普通建筑材料的坚固性与闪烁特性及PSD性能相结合。经过多年研究制备的塑料闪烁体最终满足了这些需求。此外，其生产工艺比传统塑料闪烁体要求更低、更简单，可直接将光传感器或电子器件集成到闪烁体中，为构建极紧凑且坚固的塑料探测器开辟了道路，该探测器可同时探测快中子和伽马射线。本文介绍了基于这一新概念的闪烁体的基本配方和性能，并探讨了其在中子成像和个人辐射防护中的初步应用。
英文摘要
Organic scintillators have been used for decades to detect gamma rays or fast neutrons at low cost. Despite extensive efforts it is still difficult to combine stability, ruggedness, high light yield, and decent pulse-shape discrimination (PSD) in a single scintillator material. We took the unusual approach of embedding phosphors and wavelengths shifters in a solid polyurethane matrix, trying to combine the robustness of a common construction material with scintillating properties and PSD performance. The plastic scintillators resulting from years of research ultimately meet these intentions. Moreover, the production process is less demanding and less complex than that of conventional plastic scintillators. It allows to directly integrate light sensors or electronics into the scintillator. This opens the door for the construction of extremely compact and robust plastic detectors for the simultaneous detection of fast neutrons and gamma rays. This paper presents basic recipes and properties of scintillators based on this novel conception and discusses first applications in neutron imaging and personal radiation protection.
