MaGe MC package for the GERDA and Majorana experiments — •Xiang Liu1, Reyco Henning2, Kevin Kröninger1, and Luciano Pandola21Max-Planck-Institut für Physik (Werner-Heisenberg-Institut), Föhringer Ring 6, D-80805 München — 2GERDA and Majorana MC group

The GERDA (Germanium Detector Array) and Majorana experiments are both designed to search for neutrinoless double-beta decay in 76Ge. The main issue in the design of both experiments is the reduction of background. Background can be introduced by cosmic rays and by the decay of primordial radioactive elements. The latter can be reduced by shielding with large amounts of ultrapure material.

The Monte-Carlo simulations play an important role already in design of both experiments. A detailed MC simulation is needed to optimize the shielding and additional veto systems. The shielding materials as well as the infrastructure materials close to the crystals must be very pure. The requirements on the radioactive contaminations of these materials can only be estimated through MC simulations.

A joint MC simulation framework (MaGe) based on Geant4 is being developed by the MC groups from both collaborations. The MaGe package is flexible enough for accomandating both setups as well as the test facilities. At present it is being used intensively for both experiments.

A joint apporach has many benefits: the workload for the development of general tools is shared between more experts, the code is tested in more detail, and more experimental data are available for MC validation.
