摘　　要：TlBr晶体是一种理想的的X射线和γ射线探测器材料,其原子序数高、密度大、禁带宽和电离能小,TlBr探测器具有探测效率高、能量分辨性能优异和体积小易集成等特点,可以在室温条件下使用,是核材料核查与核保障、国土安全、空间及高能物理实验的较佳选择。文章介绍了TlBr探测器工作原理及其发展与现状,对探测器结构设计及信号收集处理方法作了详细介绍,提出了TlBr探测器发展及开发工艺的建议。TIBr is a promising detector material for X - ray and γ- rays due to its high atomic number, high density, large band -gap and low ionization energy. The properties of T1Br detector are high detection efficien- cy and excellent energy resolution. It can be easily fabricated or compacted in small size, it also can be operated at room temperature. So the T1Br detector is a priority selection for nuclear material inspection and safeguards property, national security, spatial and high energy physics researches. The paper shows the principle of T1Br detector, its development and current status. The detectors＇electrode structure with signals collection and pro- cessing are introduced in detail. Lastly, there are some original ideas for component optimizing design, signal analysis method.
