The COSINUS (Cryogenic Observatory for SIgnals seen in Next-generation Underground Searches) project aims to provide a model-independent cross-check of the long-standing DAMA/LIBRA claim on the observation of dark matter. The use of sodium iodide (NaI) crystals, operated at cryogenic temperature as scintillating calorimeters, offers both a low energy threshold for nuclear recoils and the possibility to perform particle discrimination. Indeed, the dual read-out of phonon and light allows to perform signal-to-background discrimination on an event-by-event basis, a unique feature in comparison to other NaI-based dark matter searches. In this paper we will present the COSINUS detector concept together with status and future prospects of the project.

Abstract
The COSINUS (Cryogenic Observatory for SIgnals seen in Next-generation Underground Searches) project aims to provide a model-independent cross-check of the long-standing DAMA/LIBRA claim on the observation of dark matter. The use of sodium iodide (NaI) crystals, operated at cryogenic temperature as scintillating calorimeters, offers both a low energy threshold for nuclear recoils and the possibility to perform particle discrimination. Indeed, the dual read-out of phonon and light allows to perform signal-to-background discrimination on an event-by-event basis, a unique feature in comparison to other NaI-based dark matter searches. In this paper we will present the COSINUS detector concept together with status and future prospects of the project.
