Description
The GEM is one of the Micro Pattern Gas Detector (MPGD) proposed to be used as a readout for ALICE TPC upgrade in LHC experiment, at CERN [1]. The existing Multiple Wire Proportial Chamber (MWPC) will be replaced by GEM based readout which provides intrinsic ion blocking capability without any gating grid system [2]. For R&D purpose we have assembled a 10cm × 10cm triple GEM detector in IOP High Energy Detector (HED) laboratory. In this study we have performed a simulation for triple GEM detector using Garfield++ package [3]. ANSYS script is used to solve the electric fields inside the detector as well as for the graphical visualization of potentials [4]. A systematic calculation is done for gain, transparency, collection and extraction effieciency and signal distribution both for electrons and ions for this particular detector setup. Here we will present a comparison of experimental data with simulation results.
