Investigating charged particle transport through solid matter is important in those fields, such as particle induced x-ray emission analysis, where quantifying and identifying the reactions produced in the medium are of fundamental interest. A rigorous approach by solving the transfer equation means to face many difficulties most of which arise from the long range nature of the Coulomb interactions, involving more than one particle simultaneously. The common practice of neglecting the multibody collisions, though correct for rarefied neutral gases, often leads to very poor approximations, when charged particles move through dense matter. Here, we discuss a numerical simulation of the Fokker-Planck equation where the multibody collisions are taken into account. The model allows to calculate point-wise the distribution of energy and momentum transferred to the target.

The aim of this work is to analyze the diffusion and the slowing down of high energy proton shots through a target. Analyzing the phenomenon rigorously with the full transport equations, means tack ling many difficulties, most of which arise from the long range nature of the Coulomb interactions involving more than one particle simultaneously. The commonly used approach of neglecting the multi-body collisions, though correct for rarefied neutral gases, of ten leads to very poor approximations when charged particles moving through dense matter are considered. Here we present a Monte Carlo simulation of the Fokker-Planck equation where the multi-body collisions are taken into account. The model al lows the calculation of a point-wise distribution of energy and momentum transferred to the tar get
