Abstract

For the first time, the American (NASA) and Russian (ROSCOSMOS) space radiation transport codes, HZETRN and SHIELD respectively, are directly compared to each other. Calculations are presented for Galactic Cosmic Ray (GCR) minimum Hydrogen, Oxygen and Iron projectiles incident on a uniform Aluminum cylinder of varying thickness. Comparisons are made for the flux spectra of neutrons, light ions (Z≤ 2), heavy ions (Z> 2) and pions emitted from the back of the Aluminum cylinder. In order to provide more benchmark comparisons, some calculations with the GEANT and FLUKA transport codes are also shown.

摘要

首次对美国（NASA）和俄罗斯（ROSCOSMOS）的空间辐射传输代码 HZETRN 和 SHIELD 进行了直接比较。计算了银河宇宙射线（GCR）最小氢、氧和铁射弹撞击不同厚度均匀铝圆柱体的情况。比较了从铝圆柱体背面发射的中子、轻离子（Z≤2）、重离子（Z＞2）和π介子的通量谱。为了提供更多的基准比较，还展示了一些使用 GEANT 和 FLUKA 传输代码的计算。
