Multi-dimensional numerical modelling of heavy ion transport in matter using a fast and accurate method

Abstract : Simulations of ion slowing-down beams in thick targets aim at characterizing the spatial and energy distributions of incident ions inside the matter. However, to simulate the propagation of a heavy ion beam we must confront several difficulties due to the stiffness of physical phenomena. In this paper, we propose to develop a moment method with a high order accuracy numerical scheme to solve the Fokker-Planck equation. The algorithm is accurate and fast enough to be used in operational processes of dose deposition optimization. Several benchmarks are carried out and will be presented in this paper.
