In View of Large Detector Arrays: Automated Analysis Modules for COSINUS Direct Dark Matter Search — •Maximilian Gapp — Max Planck Institut für Physik, Garching, Deutschland

One unresolved issue is the explanation for the annual modulation in the rate of interactions in sodium iodide (NaI) crystals detected by DAMA/LIBRA, which is consistent with the expected dark matter signal. The COSINUS (Cryogenic Observatory for SIgnatures seen in Next generation Underground Searches) experiment has been designed to cross-check the long-standing results of the DAMA/LIBRA experiment. This will be achieved by employing cryogenic NaI calorimeters, which have low energy thresholds, and by introducing particle identification techniques through the use of an additional channel. In order to achieve this, it is necessary to test and characterize a significant number of detector prototypes. Furthermore, the COSINUS experiment plans to operate 16 channels initially and 48 subsequently. Given the substantial volume of data that will be generated, it is impractical to analyze the raw data manually. One solution is to automate the analysis chain wherever feasible. This contribution presents the analysis workflow for characterizing new prototypes and highlights potential avenues for automation.
