DESCRIPTION:Speakers: Andrea Ianni (Princeton University)\nThe DarkSide Co
 llaboration has started consideration of DarkSide-20k\, a direct WIMP sear
 ch with a Liquid Argon Time Projection Chamber (LAr-TPC) with an active (f
 iducial) mass of 23 (20) tonnes.  The DarkSide-20k LAr-TPC will be deploye
 d in the shield/veto facility already built in support of the DarkSide-50 
 experiment in the Gran Sasso underground laboratory (LNGS). DarkSide-20k w
 ill be a detector with ultra-low background levels\, the ability to measur
 e its backgrounds in situ\, and sensitivity to WIMP-nucleon interactions w
 ith cross sections of 9×10E-48 cm2 (9x10E-47 cm2) for WIMPs of 1 TeV/c2  
 (10 TeV/c2) mass\, achieved in a background-free exposure of 100 t yr accu
 mulated in a run of 5 yr.  We believe\, in particular\, that the ability t
 o identify\, measure\, and reject background will ultimately define the se
 nsitivity of direct dark matter searches.  The sensitivity of DarkSide-20k
  compares favourably with the sensitivity of other projects to start data 
 taking before 2020.  DarkSide-20k could become the most powerful dark matt
 er experiment searching for high mass dark matter to start data taking by 
 2020.  The use of the two-phase argon technology afford a sharp definition
  of the fiducial volume e effecting a strong reduction of the systematic e
 rror that dominates the measurement of 7Be neutrinos in Borexino.  To meet
  this challenge\, DarkSide-20k will exploit the auxiliary facilities inclu
 ding radon-free clean rooms\, already built at LNGS as part of the DarkSid
 e program.  It will also use the water muon veto constructed for the DarkS
 ide program.  DarkSide-20k will be instrumented with SiPMs as photosensors
  and will establish the entire chain of production\, purification\, transp
 ort\, and storage of low-radioactivity argon at the multi-tonne level.  In
  short\, DarkSide-20k will perform the most sensitive search for dark matt
 er yet proposed and will also provide a convincing foundation for a 100 t 
 scale detector.  A summary of the future experiment and the improvement of
  the existing facilities will be presented.\n\nhttps://indico.particle.mep
