Measurement of azimuthal dependent cosmic muon flux by 2\,m\,$\times$\,2\,m RPC stack near Equator at IICHEP-Madurai

The proposed 50 \,kton\, INO-ICAL experiment is an underground high energy physics experiment planned to be built at Theni, India ($9^{\circ}57'N$, $77^{\circ}16'E$) to study various parameters of neutrino oscillations using atmospheric neutrinos. The Resistive Plate Chamber (RPC) has been chosen as the active detector element for the ICAL detector. An experimental setup consisting of 12 layers of glass RPCs of size \,$\sim$\,2\,m\,$\times$\,2\,m has been built at IICHEP, Madurai to study the performance and long-term stability of RPCs produced on a large scale in the Indian industry as well as its readout electronics. In this study, the azimuthal dependence of muon flux at different zenith angles at Madurai ($9^{\circ}56'N,78^{\circ}00'E$ and altitude of about 160\,m from sea level) are presented along with the comparison of CORSIKA and HONDA predictions.
