Geant-4 simulation for space based GeV detector

Abstract

The thesis presents an extensive analysis of the modeling of a space-based GeV detector, using the GEANT-4 toolkit. The main goal is to develop and verify a detection system to identify and characterize high-energy particles in space, emphasizing precise position hits & energy deposition measurements. This research is driven by the need for sophisticated detection systems in space missions focused on investigating γ rays. The GEANT-4 simulation framework is used to simulate the physical processes and interactions of particles with detector materials. The detector design includes an anti-coincidence and tracking module for accurate hit positions and energy deposition measurements. The study includes the thorough layout of the detector geometry, the execution of primary particle creation, and the simulation of particle interactions. The thesis incorporates the analysis of a simulated model for the hits and the energy deposition measurement. The results indicate the detector’s ability to detect the particles coming onto it by specifying the coordinates where they hit the detectors, precisely quantify the energy of arriving particles, and furnish dependable data for subsequent scientific investigation. This study advances the construction of space-based detectors, which will be more sophisticated and improve our understanding of high-energy particle environments in space. This work demonstrates the versatility and efficiency of the GEANT-4 toolkit in detector simulation while offering significant insights for future space missions and the progression of spacebased high-energy particle detection technology.
