Description

For a fully model-independent investigation of the nature of the DAMA/LIBRA signal, experiments which use the same material as DAMA/LIBRA are mandatory.
COSINUS will use crystals of NaI, however not operating them as mere scintillation detectors, but as so-called cryogenic scintillating calorimeters cooled to milli-Kelvin temperatures. COSINUS detectors provide a simultaneous and independent measurement of both the temperature signal and the scintillation light signal caused by a particle interaction. Since the amount of produced light depends on the particle type (light quenching), this detection technique yields identification of the type of interacting particle on an event-by-event basis.
In this talk we will show new results from the latest generation of COSINUS prototype detectors utilizing the so-called „remoTES“ readout concept. Furthermore we will present on the current status of the experimental setup installation presently ongoing at the Gran Sasso underground lab in Italy.
