Description
Gaseous Detectors are key components of particle detectors in High Energy Physics (HEP) experiments. The Gas Electron Multiplier (GEM) is one such detector being used in contemporary HEP experiments due to its good timing resolution, High-rate handling capability, good spatial resolution, and radiation tolerance. The optimal performance of gaseous detector depends on the choice of gases being used as ionising medium. Fluorine (F)-based gases, specially CF$_{4}$ are commonly used in particle detectors. Due to environmental concerns, fluorine based gases are no more considered appropriate for gaseous detectors. As a result, there is a need to find environment friendly alternatives while maintaining the performance of the detector. In this direction, we studied the possibility of using HFO gas as a replacement for CF$_{4}$ gas in Ar/CO$_{2}$ based gas mixture in GEM detectors. We performed this study to evaluate the timing resolution of the GEM detectors. The addition of CF$_{4}$ improves the timing resolution to the order of a few nanoseconds. The timing resolution of GEM detectors with only Ar/CO$_{2}$ mixture is more than 10 nanoseconds(ns). In our study, we evaluate the possibility of improving the timing resolution with the use of HFO.
