Abstract
DarkSide program utilizes the 39Ar-depleted argon as target and the dual-phase Time Projection Chamber (TPC) technology to search for WIMP signal. In this talk, I will review the recent results
of the DarkSide-50 experiment, currently running at LNGS with 50-kg fiducial mass. Then I will present the status of the DarkSide-20k experiment with 20-tonne fiducial mass, with an emphasis on
the progress of cryogenics construction and test, and the R&D towards the finalization of the TPC design. Plans for a further step towards a 300-ton detector and a dedicated 1-ton scale detector
for low-mass WIMP will be briefly introduced as well.
