Study of Particle Multiplicity by 2 m$$\times $$2 m Resistive Plate Chamber Stack at IICHEP-Madurai

An experimental setup consisting of 12 layers of glass Resistive Plate Chambers of size 2 m\(\times \)2 m has been built at IICHEP-Madurai to study the long-term performance and stability of RPCs produced on large scale in Industry. In this study, the data obtained by this setup was analysed to find out the events where more than one particle passed through the stack within a single trigger window. The results obtained from observation was then compared with simulation using CORSIKA and GEANT4.
