Description
The dark matter interpretation of the DAMA/LIBRA annual modulation signal represents a long standing open question of the Astro-particle physics field. The SABRE experiment aims to test such claim bringing the same detection technique to an unprecedented sensitivity. Based on ultra-low background NaI(Tl) scintillating crystals as DAMA, SABRE features a liquid scintillator veto system, surrounding the main target, and it deploys twin detectors: one in the Northern hemisphere at Laboratori Nazionali del Gran Sasso, Italy (LNGS) and the other, first of its kind, in the Southern Hemisphere, in the Stawell Underground Physics Laboratory (SUPL). The first very-high purity crystal produced by the collaboration was shipped to LNGS in 2019 for characterization. It features a potassium contamination of the order of 4 ppb, about 3 times lower than DAMA/LIBRA crystals, measured by inductively coupled plasma mass spectroscopy (ICP-MS). The first phase of the SABRE experiment is a Proof of Principle (PoP) detector to be operated inside a liquid scintillator veto at LNGS. This talk will present the results of the stand-alone characterization of the first SABRE high-purity crystal, as well as the status of the PoP detector, which was commissioned early in the summer of 2020.
