Abstract

Using Monte Carlo simulation, we present the impact of contamination particles in the build-up region and their effect on the divergence between Monte Carlo simulations and experimental measurements in this region. Two types of medical accelerators are studied: Elekta Synergy MLCi2 and Varian 2100C. Monte Carlo calculations are performed by the multi-threaded code G4Linac_MT, compiled and executed on the HPC-Marwan computing grid. The Monte Carlo simulations are validated by experimental measurements of percentage dose at depth in a water phantom. The results obtained indicate that the dose divergence in the build-up region increases with the appearance of contamination particles. The contamination particles detected in the build-up region are electrons and positrons for the 6 MV photon beam and other particles are added for the high energy 18 MV beam, including protons and neutrons. The agreement between the Monte Carlo simulation becomes more accurate after the electron equilibrium depth.

Biography

Mustapha Assalmi is currently a Ph.D. student at the Multidisciplinary Faculty of Nador, Mohammed First University, Morocco. His work has focused on the optimization of Monte Carlo codes used in radiation physics simulation. Their current project is the Monte Carlo simulation of the medical linear accelerator. He teaches Moroccan grids (Magrid and HPC-marwan) for students in Master 1 GNSS, both grids are based on the different task management languages JDL for MaGrid and Slurm for HPC-marwan. Mustapha Assalmi also teaches the practical work of the module "electromagnetism in vacuum" for students in mathematics and computer science.
