Abstract

Binary thin detecting elements on a base of ⁶Li₂O∗2SiO₂:Ce/⁷Li₂O∗2SiO₂:Ce:Ce glass and Gd_1.5Y_1.5Al_2.5Ga_2.5O₁₂:Ce,Mg/Y₃Al_2.5Ga_2.5O₁₂:Ce,Mg ceramic scintillators were evaluated for detection of neutrons. Coupling in the detecting unit of neutron-sensitive and insensitive materials with separate photosensors allows the application of different techniques to discriminate gamma-rays background. Sufficient difference in scintillation kinetics of Gd_1.5Y_1.5Al_2.5Ga_2.5O₁₂:Ce and Y₃Al_2.5Ga_2.5O₁₂:Ce,Mg allows pulse shape discrimination of gamma-rays of the same energy in a phoswich detecting unit when one photosensor is utilized.

以6Li2O∗2SiO2:Ce/7Li2O∗2SiO2:Ce:Ce玻璃和Gd1.5Y1.5Al2.5Ga2.5O12:Ce,Mg/Y3Al2.5Ga2.5O12:Ce，Mg陶瓷闪烁体为基础，评价了二元薄探测元件对中子的探测效果。耦合在中子敏感和不敏感材料的探测单元与单独的光传感器允许应用不同的技术来区分伽马射线背景。Gd1.5Y1.5Al2.5Ga2.5O12:Ce和Y3Al2.5Ga2.5O12:Ce，Mg在闪烁动力学上有足够的差异，当使用一个光传感器时，可以在一个光开关检测单元中对相同能量的伽马射线进行脉冲形状识别。
