Effective Gain and Ion Back Flow study of triple and quadruple GEM detector

Abstract Gas electron Multipliers (GEM) are a new generation of gaseous avalanche devices in the Micro Pattern Gaseous Detector (MPGD) category. GEMs widely used both nuclear and high energy experiments as well medical science. Several parameters define performance these types under various experimental conditions. This article focuses on study effective gain Ion Back Flow (IBF) triple quadruple GEM detectors. Effective IBF two most important determining
