Simulation of a new hybrid MPGD with improved time resolution and decreased discharge probabilities using Garfield++

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 Ar/CO2(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.
