The SABRE experiment aims to find dark matter through the annual modulation in NaI(Tl) crystals’ rate. The goal is to carry out an independent test of the signal observed by DAMA/LIBRA, achieving a background rate significantly lower than 1 counts/day/kg/keV with ultra radio-pure crystals. A Proof-of-Principle was operated at LNGS in 2020 and measured a rate of 1.20±0.05 counts/day/kg/keV, the lowest ever reached after DAMA/LIBRA. The background model suggests that a large part of this rate is due to the 210Pb contamination in the reflector surface and in the crystal bulk. In this seminar we present strategies to further reduce the background and plans for the full scale detector.
