本文研究了具有小边缘（边缘小于10 μ m）的单、双THGEM探测器（有效面积为5 × 5cm ~ 2）的气体增益和能量分辨率。单、双THGEM探测器的最大增益分别可达5 × 103和2 × 105，而不同孔径和厚度的单、双THGEM探测器对5.9keV X射线的能量分辨率在18%~ 28%之间变化在大气压下，气体（氩气、氖）和少量其它气体（异丁烷、甲烷）。
The gas gain and energy resolution of single and double THGEM detectors (5{\times}5cm2 effective area) with mini-rims (rim is less than 10{\mu}m) were studied. The maximum gain can reach 5{\times}103 and 2{\times}105 for single and double THGEM respectively, while the energy resolution of 5.9 keV X-ray varied from 18% to 28% for both single and double THGEM detectors of different hole sizes and thicknesses.All the experiments were investigated in mixture of noble gases(argon,neon) and small content of other gases(iso-butane,methane) at atmospheric pressure.
