Abstract

The growing interest in clarifying the controversial situation in the Dark Matter sector has driven the experimental efforts towards new ways to investigate the long-standing DAMA/LIBRA result. Among them, low-temperature calorimeters based on Na-containing scintillating crystals offer the possibility to clarify the nature of the measured signal via particle identification. Here we report the first measurement of Na-containing crystals, based on material different from NaI, i.e. Na $_2$ Mo $_2$ O $_7$ and Na $_2$ W $_2$ O $_7$ , pointing out their excellent performance in term of energy resolution, light yield, and particle identification.
