Abstract

A nonperturbative analytic solution of the high charge and energy (HZE) Green's function is used to implement a computer code for laboratory ion beam transport in multiple-layered materials. The code is established to operate on the Langley nuclear fragmentation model used in space engineering applications. Computational procedures are established to generate linear energy transfer (LET) distributions for a specified ion beam and target for comparison with experimental measurement. Comparison with 56Fe ion with Pb-Al and Pb-(CH2)x targets shows reasonable agreement.

摘要

利用高电荷与能量（HZE）格林函数的非微扰解析解来实现用于多层材料中实验室离子束传输的计算机代码。该代码基于空间工程应用中使用的兰利核碎裂模型构建。建立了计算程序，以生成特定离子束和靶材的线性能量转移（LET）分布，用于与实验测量结果进行比较。与铅 - 铝和铅 - （CH2）x靶材的56Fe离子的比较显示出合理的一致性。
