摘要:

本研究针对粒子探测应用,特别是中子和α辐射环境,探究多晶金刚石的闪烁特性。多晶金刚石在保留关键探测性能的同时,为单晶金刚石提供了经济高效的替代方案。通过光致发光测量分析发射光谱,揭示了基于杂质含量和结晶度的独特特征。利用硅光电倍增管(SiPMs)评估闪烁响应,证明多晶金刚石粉末能对α辐照作出响应,尽管分辨率低于传统闪烁体。通过将金刚石粉末与中子敏感材料${}^6$LiF结合开发了原型中子探测器,并通过实验测试和Geant4模拟评估其性能。研究结果表明,多晶金刚石基探测器可实现显著的探测效率,同时对伽马辐射不敏感,为便携式中子探测应用提供了潜力。

英文摘要:

This study investigates the scintillation properties of polycrystalline diamond for particle detection applications, particularly in neutron and alpha radiation environments. Polycrystalline diamonds provide a cost-effective alternative to monocrystalline diamonds while retaining essential detection properties. Photoluminescence measurements were performed to analyze emission spectra, revealing distinct characteristics based on impurity content and crystallinity. Scintillation responses were assessed using Silicon Photomultipliers (SiPMs), demonstrating the capability of polycrystalline diamond powders to respond to alpha irradiation, albeit with reduced resolution compared to traditional scintillators. A prototype neutron detector was developed by combining diamond powder with neutron-sensitive ${}^6$LiF, and its performance was evaluated through experimental testing and Geant4 simulations. The findings indicate that polycrystalline diamond-based detectors can achieve significant detection efficiency while remaining insensitive to gamma radiation, offering potential for portable neutron detection applications.
