本特别报告介绍了专门用于模拟液态水中轨道结构 (TS) 和相关物理量（例如范围、制动力、平均自由程...）的 Geant4-DNA 用户应用程序。这些示例应用程序包含在 Geant4 Monte Carlo 工具包中，并且可以开放获取。描述了每个应用，并显示了与最新国际建议（例如 ICRU、MIRD）（如果有）的比较。讨论了 Geant4-DNA 中可用的物理模型对模拟液态水中电子相互作用的影响。得益于这些应用，作者表明，与 Geant4-DNA 中最初提供的默认模型集（选项 2）相比，Geant4-DNA 中可用的最新物理模型集（所谓的选项 4 和选项 6 集）能够更准确地模拟液态水中的阻止本领、剂量点内核和 W 值。它们还可以作为对 TS 模拟感兴趣的 Geant4-DNA 用户的参考应用程序。
This Special Report presents a description of Geant4-DNA user applications dedicated to the simulation of track structures (TS) in liquid water and associated physical quantities (e.g., range, stopping power, mean free path...). These example applications are included in the Geant4 Monte Carlo toolkit and are available in open access. Each application is described and comparisons to recent international recommendations are shown (e.g., ICRU, MIRD), when available. The influence of physics models available in Geant4-DNA for the simulation of electron interactions in liquid water is discussed. Thanks to these applications, the authors show that the most recent sets of physics models available in Geant4-DNA (the so-called option4 and option 6 sets) enable more accurate simulation of stopping powers, dose point kernels, and W-values in liquid water, than the default set of models (option 2) initially provided in Geant4-DNA. They also serve as reference applications for Geant4-DNA users interested in TS simulations.
