Study of High Energy Lepton Gamma Rays and Hadron Interactions in Particle Detectors

Abstract

The Quantum Field Theory (QFT) of constituent part in high-energy physics motivates every researcher for tracking the ultimate structure of matter. The present research work have been carried out using a muon telescope to conduct experimental and Geant4 based simulation studies to understand the concept of electroweak and hadronic interactions with matter. The muon telescope is a new experimental setup after the Geiger Muller detector and NaI detector in our Detector Physics laboratory. This is an outcome of the collaboration between D.E.I and T.I.F.R, Mumbai under which the Institute has acquired plastic scintillation detectors from Cosmic Ray Laboratory, Ooty for research purpose. The Nuclear Electronics for the NIM has been setup in the laboratory along with a characteristic study of secondary cosmic rays. It is analyzed through a basic and advanced educational activity for post graduate (PG) students. The correlation between muon count rate corresponding to temperature and atmospheric pressure is also discussed to study Decoherence curve. It is nothing but measure of the muon coincidence rate as function of distance variation among the detectors. It mainly helps to determine one of the most interesting aspect of cosmic ray showers i.e. energy of primary particle. newlineFurther discussion includes Geant4 based simulation of the muon telescope on implementation of a G4EMStandard Physics model for study of electroweak interactions in muon and gamma radiations. There are certain parameters which can t be performed through an experiment such as multiple coulomb scattering (MCS) phenomena and cross-section of muon interaction processes, effect of surface characteristics of detectors on photon yield, Compton Effect. These concepts also been considered in this simulation study. newlineThe study of hadronic interactions is based on medical application i.e. Hadrontherapy, where proton beams are used for curing tumors. The physical characteristics of proton beam such as stopping power and range and its equivalent dose for speci
