描述了一个基于GEANT4仿真工具包的物理仿真软件框架MAGE。MAGE用于模拟超低放射性本底探测器对电离辐射的响应，特别是Majorana和Gerda无中微子双β衰变实验。Majorana和Gerda使用高纯度锗探测器来搜索Ge-76的无中微子双β衰变，MAGE是这两个合作伙伴共同开发的。MAGE框架包含了常见物体、原型、试验台和实际实验的几何模型。它还实现了定制的事件生成器、GEANT4物理列表和输出格式。所有这些功能都以类库的形式提供，这些类库通常被编译成单个可执行文件。用户在运行时通过宏选择特定的实验设置实现。将所有这些公共类组合到一个框架中，减少了重复工作，简化了模拟数据和实验之间的比较，并简化了要模拟的新检测器的添加。本文重点介绍了软件框架、定制事件产生器和物理列表。
We describe a physics simulation software framework, MAGE, that is based on the GEANT4 simulation toolkit. MAGE is used to simulate the response of ultra-low radioactive background detectors to ionizing radiation, specifically the MAJORANA and GERDA neutrinoless double-beta decay experiments. MAJORANA and GERDA use high-purity germanium detectors to search for the neutrinoless double-beta decay of Ge-76 and MAGE is jointly developed between these two collaborations. The MAGE framework contains the geometry models of common objects, prototypes, test stands and the actual experiments. It also implements customized event generators, GEANT4 physics lists and output formats. All of these features are available as class libraries that are typically compiled into a single executable. The user selects the particular experimental setup implementation at run-time via macros. The combination of all these common classes into one framework reduces duplication of efforts, eases comparison between simulated data and experiment and simplifies the addition of new detectors to be simulated. This paper focuses on the software framework, custom event generators and physics lists.
