Polystyrene based scintillation detector studies in Astro particle Physics and medical physics

Abstract

DEASA (Dayalbagh Educational Air Shower Array) consists of eight plastic scintillators each with an area of 1 square meter. The cosmic ray showers have been simulated in CORSIKA [1] for the different primary particles in the energy range of 1014- 1015 eV. The longitudinal and lateral profiles have been studied for Agra. The real-life applications of cosmic ray particles in space have been studied to protect the astronaut from the galactic cosmic rays [2]. A plastic scintillation detector is simulated in Geant4 to study applications in hadron and carbon ion therapy [3]. The proton and carbon beam are simulated through the tumour region to study the stopping power and depth dose distribution for different organs. The energy range for each study is optimized and the Bragg curve is then interpreted with Bragg peak position and range.
