摘　　要：设计研制了一种双能气体探测器,通过模拟计算研究了探测器应用于物质识别的可行性。在模拟计算的基础上制造了双能气体探测器样机,并对4种不同种类的物质进行了X射线透射实验。实验结果表明,双能气体探测器具备物质识别能力。研究了双能气体探测器的刻度校正方法,该方法可有效提高探测器不同探测单元间的一致性。In this paper, a dual-energy gas detector was designed, and the simulation research was taken to validate its feasibility in material discrimination. On the base of simulation, the prototype of dual-energy gas detector was developed and X-ray transmission experiment was done for four kinds of materials. The experiment results show that the dual-energy gas detector possesses the ability of material discrimination. The calibration method of dual-energy gas detector was studied, and it can improve the consistency of detector units.
