The Status of the COSINUS Experiment — •Maximilian Hughes for the COSINUS collaboration — Max-Planck-Institut für Physik

COSINUS (Cryogenic Observatory for SIgnatures seen in Next generation Underground Searches) is a dark matter direct detection experiment using cryogenic sodium iodide (NaI) modules. The goal is a model independent test of the DAMA/LIBRA dark matter claim. Prototype modules using the remoTES to read out heat signals from NaI have been measured and the results will be presented. The underground facility construction is complete and the dry dilution refrigerator to provide the milli-kelvin temperatures required has been commissioned. The water Cherenkov muon veto surrounding the cryostat has been installed and filled with water. The next steps include installing cabling and superconducting quantum interference devices (SQUIDs) to read out the modules. The first data taking is planned to start in 2025 with eight 30 gram NaI modules.
