Abstract: The DarkSide-50 direct dark matter detector is a liquid argon time projection chamber (TPC) surrounded by a liquid scintillator neutron veto (LSV) and a water Cerenkov muon veto (WCV). Located under 3800 m.w.e. at the Laboratori Nazionali del Gran Sasso, Italy, it is the only direct dark matter experiment currently operating background free. The atmospheric argon target was replaced with argon from underground sources in April, 2015. The level of Ar-39, a beta emitter present in atmospheric argon (AAr), has been shown to have been reduced by a factor of (1.4 +/- 0.2) x 10(3). The combined spin-independent WIMP exclusion limit of 2.0 x 10(-44) cm(2) (m(chi) = 100 GeV/c(2)) is currently the best limit on a liquid argon target.
