Meregaglia,a / A b s t r a c t : DarkSide is a graded experimental project based on radiopure argon, and is now, and will be, used in direct dark matter searches. The present DarkSide-50 detector, operating at the Gran Sasso National Laboratory, is a dual-phase, 50 kg, liquid argon time-projection-chamber surrounded by an active liquid scintillator veto. It is designed to be background free in 3 years of operation. DS-50 performances, when filled with atmospheric argon, are reported. However DS-50 filled with underground argon, shows impressive reduction of the 39Ar isotope. The application of this powerful technology in a future generation of the DarkSide program is discussed. K e y w o r d s : Time projection Chambers (TPC); Noble liquid detectors (scintillation, ionization, double-phase); Large detector systems for particle and astroparticle physics; Dark Matter detectors (WIMPs, axions, etc.)
