在这项工作中，一个新的混合MPGD由两个GEM箔和金属网提出。仿真结果表明，与三重GEM设计相比，该设计能显著缩短信号的上升时间，并具有更好的颗粒识别性能。计算了不同电压设置下的增益，为以后的实验提供参考。仿真结果还表明，与三重GEM探测器相比，时间和空间分辨率也有所提高。研究了在不同漂移电场强度下，混合探测器（70/30）和Ar/异丁烷（95/5）的时间和空间分辨率。这种新型混合探测器在基础研究和成像应用方面都显示出很好的潜力。
In this work, a new hybrid MPGD consisting of two GEM foils and a metallic mesh was proposed. Based on the simulation studies, this design can significantly reduce the rise time of signal and has a better performance in respect of particle identification compared with the triple GEM design. The gain with various voltages setting was computed in order to provide us references for future experiment. The simulation results also show that the time and space resolution compared to the triple GEM detector are also improved. The time and space resolution of hybrid detector with(70/30) and Ar/isobutane(95/5) were investigated for various drift electric field intensities. This new hybrid detector shows excellent potential for both fundamental research and imaging applications.
