Abstract

A mathematical model of proton transport in matter is considered. The interaction of protons with the electron subsystem of the medium’s atoms is modeled in the approximation of the average energy loss during ionization scattering. Nuclear interactions are considered in the model of individual collisions. An algorithm for modeling proton transfer in piecewise-homogeneous media is developed, combining the continuous deceleration approximation when interacting with electrons with the implicit direct modeling of elastic and inelastic scattering on the nuclei. The calculations that demonstrate the effect of nuclear scattering on the distribution of the energy released by protons during scattering are presented.

质子传输的模拟

摘要

考虑质子在物质中传输的数学模型。质子与介质原子电子子系统的相互作用以电离散射过程中平均能量损失的近似值来模拟。在单个碰撞模型中考虑了核相互作用。提出了一种在分段均质介质中质子传递建模的算法，将与电子相互作用时的连续减速近似与原子核上弹性和非弹性散射的隐式直接建模相结合。提出了表明核散射对质子在散射过程中释放的能量分布的影响的计算。
