Abstract

A new type of a galactic cosmic rays (GCR) simulator, provided at the JINR Laboratory of Radiation Biology, is potentially capable of generating a complex radiation field with inclusions of a variety of ions with a wide energy range and with required abundance at the charged particle accelerators. This complex multicomponent radiation field simulates radiation environment inside a spacecraft during an interplanetary flight, for example, to Mars. The article provides an analytical description of the GCR simulator as well as a description of a specially developed software that enables selection of necessary parameters of a simulator model for creating relevant mixed radiation conditions. The software implements processing of data obtained with Monte Carlo-based FLUKA and PHITS programs, fitting and optimization of model parameters as well as data visualization tools.

新型银河宇宙射线模拟器的计算机建模

JINR 辐射生物学实验室提供的一种新型银河宇宙射线（GCR）模拟器有可能产生一个复杂的辐射场，其中包含各种离子，其能量范围很广，并具有带电粒子加速器所需的丰度。这种复杂的多成分辐射场可以模拟航天器在星际飞行（例如飞往火星）过程中的辐射环境。文章对 GCR 模拟器进行了分析描述，并介绍了专门开发的软件，该软件可以选择模拟器模型的必要参数，以创建相关的混合辐射条件。该软件可以处理通过基于蒙特卡洛的 FLUKA 和 PHITS 程序获得的数据、拟合和优化模型参数以及数据可视化工具。

期刊介绍： The focus of CPC is on contemporary computational methods and techniques and their implementation, the effectiveness of which will normally be evidenced by the author(s) within the context of a substantive problem in physics. Within this setting CPC publishes two types of paper. Computer Programs in Physics (CPiP) These papers describe significant computer programs to be archived in the CPC Program Library which is held in the Mendeley Data repository. The submitted software must be covered by an approved open source licence. Papers and associated computer programs that address a problem of contemporary interest in physics that cannot be solved by current software are particularly encouraged. Computational Physics Papers (CP) These are research papers in, but are not limited to, the following themes across computational physics and related disciplines. mathematical and numerical methods and algorithms; computational models including those associated with the design, control and analysis of experiments; and algebraic computation. Each will normally include software implementation and performance details. The software implementation should, ideally, be available via GitHub, Zenodo or an institutional repository.In addition, research papers on the impact of advanced computer architecture and special purpose computers on computing in the physical sciences and software topics related to, and of importance in, the physical sciences may be considered.
