| 中文摘要 | GEM探测器是一种新型微型气体探测器(Micrc-Pattern Gas Detector),在粒子物理实验及低能X射线成像系统中有着较大的应用前景．文章研制了一种适用于低能X射线成像和带电粒子径迹测量的三级GEM气体探测器．使用放射源55Fe对其气体放大特性、电荷传输效率及能量分辨本领等性能进行了实验研究,重点研究了传输区电场对气体有效增益和能量分辨本领的影响．实验结果表明,三级GEM探测器的暗电流和噪声较小,有效增益能够达到105以上并稳定地工作,对5．9keV的X射线能量分辨率可达24％,传输区电场强度大于3000V／(cm·atm)时,能量分辨率基本稳定在30％左右．; GEM gas detector is a type of Micro-pattern gas detectors, which has a wide potential in particle physics experiment and lower energy X-ray imaging system. In this paper a tri-GEM gas detector was developed, and the gas gain, energy resolution and charge transfer efficiency of the tri-GEM detector were studied with source of 55Fe. The results of the test indicate that more than 105 effective gain and about 24% energy resolution of 5.9keV X ray of the tri-GEM detector can be reached. The results also show that when the electric field in transfer region is more than 3kV/(cm穉tm), the best energy resolution of the tri-GEM detector can be obtained.; 国家自然科学基金(105T5063)资助~~ |
