Description
There is a wide range of astronomical evidence that the visible stars and gas in all galaxies, including our own, are immersed in a much larger cloud of non-luminous matter, typically an order of magnitude greater in total mass. The existence of this “dark matter” is consistent with evidence from large-scale galaxy surveys and microwave background measurements, indicating that the majority of matter in the universe is non baryonic. The nature of this non-baryonic component is still totally unknown, and the resolution of the “dark matter puzzle” is of fundamental importance to cosmology, astrophysics, and elementary particle physics.
A review and description of the DarkSide underground argon program at LNGS will be presented, focusing in particular on the technological aspects of the DarkSide-50 experiment and presenting the first preliminary results. The talk is mostly devoted to the description of the detectors (Dark Matter TPC, Neutron Veto, Muon Veto) from the design to the construction to operations; performances and results will also be shown, and plans for future detectors.
