中子探测器在从石油钻探到国土安全等领域都有应用。介绍了一种能测量从几兆电子伏到热能的中子的小型玻璃探测器的设计。所描述的探测器使用聚乙烯层和富含10 B的铈掺杂玻璃层的组合，以减慢快中子并在热能水平下捕获它们。10 B-富集的玻璃样品的生产和它们的光吸收，发射和闪烁产额性能进行了测量。然后使用GEANT 4软件模拟原型探测器的性能。还研究了几何优化和中子探测能力。
Neutron detectors have applications in fields ranging from oil drilling to homeland security. A design for a compact glass detector capable of measuring neutrons with energies from several MeV down to thermal energies is described. The detector described uses a combination of polyethylene layers and layers of Cerium-doped scintillating glass enriched with 10B in order to slow the fast neutrons and capture them at thermal energy levels. The 10B-enriched glass samples were produced and their light absorption, emission and scintillation yield properties were measured. GEANT4 software was then used to simulate a prototype detector’s performance. The geometrical optimization and neutron detection capabilities were also studied.
