Description

DarkSide uses dual-phase Liquid Argon Time Projection Chambers (TPC) to search for WIMP dark matter.
The talk will present the latest result from the current experiment, DarkSide-50, which has been running since mid-2015 and uses a 50-kg-active-mass TPC filled with argon from an underground source.
The next stage of the DarkSide program will be a new generation experiment involving a global collaboration from all the current argon-based experiments.
DarkSide-20k, based on a 20-tonne fiducial mass TPC with SiPM based photosensors, is designed to have a background well below that from coherent scattering of solar and atmospheric neutrinos.
Like its predecessor, DarkSide-20k will be housed at the Gran Sasso (LNGS) underground laboratory, and it is expected to attain a WIMP-nucleon cross section of $0^{-47}$\,cm${}^2$ for a WIMP mass of $1$\,TeV/c${}^2$ in a 5-year run.
