Abstract: We describe a physics simulation software framework, MAGE, that is based onthe GEANT4 simulation toolkit. MAGE is used to simulate the response ofultra-low radioactive background radiation 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 theneutrinoless double-beta decay of 76Ge, and MAGE is jointly developed betweenthese two collaborations. The MAGE framework contains the geometry models ofcommon objects, prototypes, test stands, and the actual experiments. It alsoimplements customized event generators, GEANT4 physics lists, and outputformats. All of these features are available as class libraries that aretypically compiled into a single executable. The user selects the particularexperimental setup implementation at run-time via macros. The combination ofall these common classes into one framework reduces duplication of efforts,eases comparison between simulated data and experiment, and simplifies theaddition of new detectors to be simulated. This paper focuses on the softwareframework, custom event generators, and physics lists.
