> Title: SABRE -- a NaI(Tl) experiment to test DAMA/LIBRA
> For over a decade, the DAMA collaboration has been observing a rate modulation in a large array of high purity NaI(Tl) crystal detectors at LNGS, which may be explained by dark matter interactions. This observation is both significant and controversial. Several experiments have claimed to rule out DAMA/LIBRA as an evidence for dark matter, but these tests were made based on dark matter halo models and dark matter- matter interaction models that are currently unknown. Therefore, the SABRE collaboration plans to carry out an unambiguous test of DAMA/LIBRA by using NaI(Tl) crystals with lower residual background than that of DAMA/LIBRA. 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.
