Abstract
The orbital motion of the Earth around the Sun is expected to produce a modulation in the interaction rate of hypothetical dark-matter particles in an Earth-based detector. The DAMA experiment has observed a signal compatible with this modulation in the scintillation light of NaI(Tl) crystals with high statistical significance. This claim has not yet been verified since the other experiments involved in this type of research employ different target materials and technologies and can not be compared with DAMA independently of the assumed theoretical model. SABRE will provide a model-independent test of the DAMA claim through the use of ultrapure NaI(Tl) crystals (same target material as DAMA) and by studying the modulation signal in both the hemispheres identifying any possible terrestrial contribution. To further reduce the background level the crystals will be placed in an active veto system. This paper presents the detector sensitivity studies in order to understand its ability to verify the DAMA claim.
