Descripción
By employing high-purity NaI as a cryogenic bolometer target material, the upcoming COSINUS experiment aims at providing a definitive crosscheck of the DAMA/LIBRA dark matter claim within the next few years. This approach is made possible through the dedicated „remoTES" detector design, which allows to readout the NaI crystal using a transition edge sensor without exposing it to fabrication processes. In combination, with ultrathin Si beaker light detectors, COSINUS modules provide event-by-event particle identification and low nuclear recoil detection thresholds on the order of few keV. Construction of the COSINUS facility at Laboratori Nazionali del Gran Sasso is finished, and commissioning of the setup is ongoing, while the final detector design is being prepared. This contribution will give an overview on the characteristics and features of the new COSINUS facility, which includes a modern, „dry“ dilution refrigeration cryostat, specialized vibration decoupling solutions, and a dedicated water cherenkov muon veto system. The ongoing R&D efforts for COSINUS detectors will be presented, with an outlook to possible future applications of the readout concept.
