Monte Carlo simulation of cosmic muon interactions in MRPC detector medium

Gas detectors are widely used in various applications, ranging from high-energy particle detection to imaging technologies. MRPC (Multigap Resistive Plate Chamber) detector structures are unique among gas detectors. Particles entering the gas volume of the MRPC detector physically interact with the gas mixture, creating a characteristic signal. Thus, information about the incoming particle is obtained. The main feature that distinguishes MRPC detectors from other RPC detectors is that they significantly improve the tracking of particles thanks to their multiple gas gaps. MRPC structures can also be combined and used in large detector systems. These structures, for example, are an essential component of the CERN ALICE experiment. In this thesis, for %90 R134a - %5 i-C4H10 - %5 SF6 , %97 R134a - %2,5 i-C4H10 - %0,5 SF6 , %50 CO2 - %45 N2 - %5 Ar , %60 CO2 - %35 N2 - %5 Ar gas mixtures, Soda-Lime Glass MRPC detector with 5 gas spaces is designed. Cosmic muons with energies of 0.5 GeV – 1.0 GeV – 2.0 GeV and 4.0 GeV are sent vertically on a Glass MRPC detector and the physical interactions that occur are examined using the FLUKA simulation software, as well as the properties that can provide the best performance are investigated.
