Research Progress of Hexagonal Boron Nitride Neutron Detector

摘要:

六方氮化硼中子探测器具有泄漏电流小、体积小、响应速度快、探测效率高、对γ射线不灵敏等优点,有望取代传统的³He气体探测器和微结构半导体中子探测器而得到广泛应用。文章介绍了六方氮化硼中子探测器的原理,从制备工艺、探测器结构、探测器性能等方面综述了六方氮化硼中子探测器近年来的研究进展。

Abstract:

Hexagonal boron nitride (hBN) neutron detectors present such advantages as small leakage current, small volume, fast response speed, high detection efficiency and insensitivity to γ-rays, thus they are expected to be widely used as supplements of the traditional ³He gas detector and microstructure semiconductor neutron detector. The principles of hBN neutron detector are introduced in this paper, and the research progressed of hBN neutron detector in recent years are also reviewed, including the preparation process of hBN films, the structure and performance of hBN neutron detectors and so on.
