We are happy to present the first paper dedicated to this: “Geant4-based electromagnetic background model for the CRESST experiment”, published in The European Physical Journal C. The paper describes the first attempt to create an electromagnetic background model for the TUM40 detector module used in CRESST-II phase 2. The combination of internal, external radiogenic and cosmogenic sources simulated with the GEANT4 toolkit gives us the possibility to explain up to 68% of the background in the energy range between 1 and 40keV. The work for this publication was performed by scientists working at HEPHY and TU Wien.
The next steps, which will allow us to improve our model, are a dedicated screening campaign of materials used in the experiment, and further studies of cosmogenic activation as well as investigation of the neutron background."
