| 中文摘要: |
| 介绍了一种气体倍增器(Gas Electron Multiplier,GEM)薄膜,研制了有效面积为10 cm×10 cm的单层GEM探测器原型机.利用55Fe 的5.9 keV的 x射线源对单层 GEM探测器的正比性,有效增益以及能量分辨率随漂移电场、GEM工作电压以及收集场的函数关系进行了测量,找到了探测器的最佳工作条件.实验结果表明,探测器的正比性良好,性能稳定.当GEM工作电压为451 V时,增益达到500,此时的能量分辨率为17.6%. |

| A Gas detector based on Gas Electron Multiplier with the sensitive area of 10 cm×10 cm is introduced.The basic performances of the GEM detector are tested with 5.9 keV x ray of 55Fe source,which are the proportional,energy resolution and effective gain with the field of drift gap,the voltage of GEM and the field of induce gap.And we found the best work condition of the detector.The results show that the detector has a good proportion and works stable.The effective gain and energy resolution is 500 and 17.6%,respectively,when the work voltage of GEM is 451 V. |
