DESCRIPTION:Speakers: Vicente Pesudo Fortes (CIEMAT / LSC)\nDarkSide-20k i
 s under construction at LNGS and is designed to lead the search for heavy 
 WIMPs in the coming years. In addition to this\, it has prospects to lead 
 other DM searches and perform relevant detections of neutrinos from the Su
 n\, the atmosphere\, and Supernovae. Argon has the advantage of pulse shap
 e discrimination compared to other noble elements\, but has the drawback o
 f the cosmogenically induced 39Ar content with an activity of 0.96 Bq/kg. 
 Getting rid of this background is pivotal for the success of our scientifi
 c program. For this reason\, the experiment will use underground Argon\, i
 n which the concentration of 39Ar is depleted by at least a factor of 1400
 . The extraction of the needed 120 tonnes will take place at the Urania pl
 ant in Colorado\, the purification at the ARIA plant in Sardinia\, and the
  characterization at the DArT experiment in Canfranc. In this talk\, I wil
 l present the sensitivity of the DarkSide-20k to different rare events and
  the status of the overall program\, with a focus on the Spanish contribut
 ions.\n\nhttps://indico.ific.uv.es/event/8035/contributions/28901/
