Simulation study of the performance of new micropattern gaseous detectors

Abstract

The micropattern gaseous detectors (MPGDs) are widely used in high-energy physics experiment, such as detector upgrade projects in LHC, due to its excellent performance on rate capability, spatial and time resolutions. In this paper, we studied the performances of GEM, FTM and $$\mu $$ -RWELL detectors on time and spatial resolutions using Monte Carlo simulation methods and compared their performances and characteristics at various working conditions. Result shows that time resolution of MPGDs improves with the increase of electric field intensity in drift region, while spatial resolution shows the reverse tendency. In addition, detectors operating with an electronegative gas mixture show better performances on both time and spatial resolution. We studied the performance of triple-GEM, FTM and $$\mu $$ -RWELL detectors with Monte Carlo simulation. In this paper, ANSYS and GARFIELD are used to build full electric field model of the detector. The time resolution and spatial resolution are derived, which are very important for triggering performance and track reconstruction ability. These results will provide references on detector design and the technology chosen in LHC detector upgrade projects.
