本文介绍了MARS14(98) -最新版本的MARS蒙特卡罗代码系统，用于快速模拟屏蔽，加速器和探测器组件中的强子和电磁级串，能量范围从电子伏特的一小部分到30 TeV。与之前的版本MARS 13相比，主要的变化涉及强子产生模型与评估数据和DPMJET-II代码进行了调整，改进了强子和μ子的光和电产生，改进了三体衰变的算法，磁场中的粒子跟踪，电子和μ子的同步辐射，显著扩展了直方图功能和材料描述，并提高了计算性能。除了直接能量沉积计算外，代码中还内置了一套新的包括中微子在内的所有粒子的影响-剂量转换因子。MARS 14（98）系统包括链接到用于20mev以下中子输运的MCNP代码，用于热和应力分析的ANSYS代码以及用于大型同步加速器和对撞机环中多圈粒子跟踪的STRUCT代码。
This paper describes MARS14(98) - the newest version of the MARS Monte Carlo code system for fast simulation of hadronic and electromagnetic cascades in shielding, accelerator and detector components in the energy range from a fraction of an electronvolt up to 30 TeV. The main changes compared to the previous release, MARS 13, concern the hadron production model tuned with evaluated data and the DPMJET-II code, improved photo- and electro- production of hadrons and muons, improved algorithms for the 3-body decays, particle tracking in magnetic fields, synchrotron radiation by electrons and muons, significantly extended histograming capabilities and material description, and improved computational performance. In addition to direct energy deposition calculations, a new set of fluence-to-dose conversion factors for all particles including neutrino are built into the code. The MARS 14(98) system includes links to the MCNP code for neutron transport below 20 MeV, to the ANSYS code for thermal and stress analyses and to the STRUCT code for multi-turn particle tracking in large synchrotrons and collider rings.
