Fast Calculation of Mont Carlo Ion Transport Code

Abstract

In this work, a Monte Carlo code has been developed for quick simulation of carbon ion bombardment in materials. This program realizes the calculation of the displacement damage and ionization of particle (<10MeV/amu) in materials. In addition, high energy carbon (<500MeV/amu) transport calculation is developed to simulate the ionization dose in water. The GPU parallel algorithm is adopted to speed up the program. Subsequently, the vacancies and ionization of target materials induced by various energy carbon iron were simulated and compared with the SRIM2013. Dose depth distributions of different energy carbon in water were simulated and compared with GSI experimental data. Results of simulation are consonant well with SRIM2013 and experimental data. It achieves significant speed-up ratio in different GPU devices.
