Description
Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) is a direct detection dark matter (DM) search experiment located at the Laboratori Nazionali del Gran Sasso in Italy. Utilizing cryogenic and scintillating crystals, CRESST searches for nuclear recoils from DM particles, and has repeatedly achieved threshold below 100 eV across a variety of target materials. However, at these energies, the ability to discriminate between potential DM signals and electromagnetic background is limited. In addition, a key challenge shared by all low-mass dark matter searches — including CRESST — is the existence of unknown event populations at very low energies known as the low energy excesses. Therefore, having a reliable background model is of utmost importance.
To address this, a comprehensive GEANT4-based simulation framework (ImpCRESST) was developed, continuously refined to reflect the current configuration and materials of CRESST’s detector modules, used to understand various background components in the measured spectra by CRESST and development of the background model.
The CRESST background model and the ImpCRESST simulation code will be presented and discussed in detail.
