摘要

溴化镧（铈）（LaBr3（Ce））闪烁探测器具有较高的能量分辨和较高的探测效率

在中子质询非破坏性检测爆炸物、违禁品及地雷等研究领域发挥了重要作用。本文提出了中子场中LaBr3（Ce）探测器宽能范围的刻度方法:分别测量中子诱发NH4Cl和三聚氰胺（C3H6N6）的瞬发能谱

对比后确定了各核素的特征峰

获得了1–10MeV能区的能量刻度曲线。采用二次多项式及三次多项式拟合

能较好地区分被测特征核素。

Abstract

Background: LaBr3（Ce） detector has played an important role in detecting explosive

contraband and landmine because of its high detection efficiency and good energy resolution etc.Purpose: To calibrate detector in wide energy region.Methods: The gamma spectra of NH4Cl and C3H6N6 induced by 252Cf neutron source were measured.Results: Comparing their gamma spectra

characteristic gamma lines can be located and the energy calibration curve was obtained.Conclusions: Radio nuclides can be identified by the calibration curve fitted with quadratic or cubic polynomial.
