Measurement of azimuthal dependent muon flux by 2 m × 2 m RPC stack at IICHEP-Madurai

The proposed 50 kton INO-ICAL experiment is an upcoming underground high energy physics experiment planned to be commissioned at Bodi hills near Theni, India *, ** to study various properties of neutrino oscillations using atmospheric neutrinos produced by extensive air shower phenomenon. The resistive plate chamber has been chosen as the active detector element for the proposed INO-ICAL. An experimental setup consisting a stack of 12 layers of glass resistive plate chambers each with a size of *** m has been built at IICHEP, Madurai to study the performance and long-term stability of the resistive plate chambers(RPCs) commercially produced in large quantities by the Indian industries as well as its electronics for the front-end and subsequent signal processing. In this study, the azimuthal dependence of muon flux at various zenith angles at Madurai **** and at an altitude of 160 m above mean sea level) has been presented along with the comparison of Monte Carlo from CORSIKA and HONDA predictions.
