由强度前沿需求驱动的MARS15规范开发
MARS15 Code Developments Driven by the Intensity Frontier Needs
摘要：
MARS 15（2012）是自1974年以来开发的多用途蒙特卡罗代码的最新版本，用于详细模拟屏蔽，加速器，探测器和航天器组件的任意3-D几何形状中的强子和电磁级联，能量范围从几分之一电子伏到100 TeV。受强度前沿项目及其兆瓦级光束需求的驱动，例如，ESS、FAIR和Project X，该代码最近得到了实质性的改进和扩展。这些包括在0.7至12 GeV能量范围内的包容性和排他性粒子事件发生器，低于20 MeV的质子非弹性相互作用建模，在1 keV至20 MeV能量范围内电磁簇射模拟的EGS 5代码的实施，化合物材料中的阻止功率描述，从几分之一eV至20-150 MeV中子的DPA计算的新模块，用户友好的基于DeTra-based的方法来计算核素库存，以及新的基于ROOT的几何结构。
英文摘要：
The MARS15(2012) is the latest version of a multi-purpose Monte-Carlo code developed since 1974 for detailed simulation of hadronic and electromagnetic cascades in an arbitrary 3-D geometry of shielding, accelerator, detector and spacecraft components with energy ranging from a fraction of an electronvolt to 100 TeV. Driven by needs of the intensity frontier projects with their Megawatt beams, e.g., ESS, FAIR and Project X, the code has been recently substantially improved and extended. These include inclusive and exclusive particle event generators in the 0.7 to 12 GeV energy range, proton inelastic interaction modeling below 20 MeV, implementation of the EGS5 code for electromagnetic shower simulation at energies from 1 keV to 20 MeV, stopping power description in compound materials, new module for DPA calculations for neutrons from a fraction of eV to 20-150 MeV, user-friendly DeTra-based method to calculate nuclide inventories, and new ROOT-based geometry.
