# Study of Particle Multiplicity of Cosmic Ray Events using 2m$\times$2m Resistive Plate Chamber Stack at IICHEP-Madurai

## TL;DR

This study uses a large-scale Resistive Plate Chamber array to measure cosmic ray particle multiplicity and compares the results with various hadronic interaction models in simulations.

## Contribution

It presents the first long-term performance analysis of large-scale RPCs in India and compares experimental data with multiple hadronic models.

## Key findings

- Measured charged particle multiplicity from cosmic rays
- Assessed RPC stability over time
- Compared experimental data with CORSIKA models

## Abstract

An experimental setup consisting of 12 layers of glass Resistive Plate Chambers (RPCs) of size 2\,m\,$\times$\,2\,m has been built at IICHEP-Madurai (\ang{9;56;14.5}\,N \ang{78;00;47.9}\,E, on the surface) to study the long term performance and stability of RPCs produced on large scale in Indian industry. This setup has been collecting data triggered by the passage of charged particles. The measurement of the multiplicity of charged particles due to cosmic ray interactions are presented here. Finally, the results are compared with different hadronic models of the CORSIKA simulation.
