To test and to develop Geant4 (Geometry And Tracking version 4) Monte Carlo hadronic models with focus on applications in a space radiation environment.
The Monte Carlo simulations have been performed using the Geant4 toolkit. Binary (BIC), its extension for incident light ions (BIC-ion) and Bertini (BERT) cascades were used as main Monte Carlo generators. For comparisons purposes, some other models were tested too. The hadronic testing suite has been used as a primary tool for model development and validation against experimental data.
The Geant4 pre-compound (PRECO) and de-excitation (DEE) models were revised and improved. Proton, neutron, pion, and ion nuclear interactions were simulated with the recent version of Geant4 9.4 and were compared with experimental data from thin and thick target experiments.
The Geant4 toolkit offers a large set of models allowing effective simulation of interactions of particles with matter. We have tested different Monte Carlo generators with our hadronic testing suite and accordingly we can propose an optimal configuration of Geant4 models for the simulation of the space radiation environment.
使用 Geant4（几何和追踪版本 4）蒙特卡罗强子模型进行测试和开发，重点关注空间辐射环境中的应用。
使用 Geant4 工具包进行蒙特卡罗模拟。二进制（BIC）、其用于入射轻离子的扩展版本（BIC-ion）和 Bertini（BERT）级联被用作主要的蒙特卡罗生成器。出于比较目的，还测试了其他一些模型。强子测试套件已被用作模型开发和验证实验数据的主要工具。
修订和改进了 Geant4 预复合（PRECO）和退激发（DEE）模型。使用 Geant4 最新版本 9.4 模拟了质子、中子、介子和离子核相互作用，并与来自薄靶和厚靶实验的实验数据进行了比较。
Geant4 工具包提供了一组大型模型，允许有效地模拟粒子与物质的相互作用。我们使用强子测试套件测试了不同的蒙特卡罗生成器，并相应地提出了用于模拟空间辐射环境的 Geant4 模型的最佳配置。
