Description
The dark matter claim by DAMA/LIBRA is both significant and controversial. Several experiments have claimed to rule out DAMA/LIBRA, but the claims are made based on astrophysical and nuclear models that are unknown. Therefore, an unambiguous test of DAMA/LIBRA can only be made using NaI(Tl) crystals with lower residual background than that of DAMA/LIBRA, and the SABRE experiment is well equipped to achieve this goal. I will report the development of ultra-high purity SABRE NaI(Tl) crystals, the study of NaI(Tl) scintillation efficiency under Na nuclear recoils, and the progress of SABRE toward testing DAMA/LIBRA.
