Monte Carlo Simulations of Bragg Peak Curves for Mono-Energetic Proton Beams
Article Sidebar
Main Article Content
Abstract
As an energetic proton beam penetrates into
matter its energy loss rate (stopping power) increases with
penetration depth reaching a maximum value in a region
known as Bragg peak. The main objective of this study is to
determine the penetration depths of mono- energetic
protons in water using Monte Carlo simulations.. The
outputs of the simulations were analysed using ROOT
analysis software. Validation of the Monte Carlo model was
carried out by comparing proton ranges in water obtained
with Geant4 simulations against data obtained from the
NIST database. The simulation results were in excellent
agreement (within an approximately 0.5% uncertainty) with
NIST data.
