RETGEM探测器的初步测试

Preliminary Test of Thick GEM with Resistive Electrodes

摘要: 研制了一种新型的带有阻抗性电极的TGEM——RETGEM(Thick GEM with Resistive Electrodes)探测器，阻抗性电极可以有效地保护探测器和前端电子学免于偶尔放电的损伤。对RETGEM探测器进行了初步测试，其中包括计数率、能量分辨、增益以及打火率。结果表明，探测器达到了设计的基本要求。 In this study we present preliminary results from a new detector: a thick gaseous electron multiplier(GEM) with resistive electrodes. The resistive electrodes protect the detector and the frontend electronics from damage by occasional discharges. In different gas mixtures, we test Thick GEM with Resistive Electrodes(RETGEM) detector for the first time, including counting rate, energy resolution, effective gain, and discharge probability. The results can satisfy the basic demand of RETGEM detector design.
