  At present the results in the field of direct dark matter search are in
tension: the positive claim of DAMA/LIBRA versus null results from other
experiments. However, the comparison of the results of different experiments
involves model dependencies, in particular because of the different target
materials in use. The COSINUS R&D project aims to operate NaI as a cryogenic
calorimeter. Such a detector would not only allow for a direct comparison to
DAMA/LIBRA, but would also provide a low(er) nuclear recoil threshold and
particle discrimination.
