Dual phase noble liquid Time Projection Chambers (TPCs) offer a
competitive and scalable way to search for dark matter directly via
elastically scattering off of detector target nuclei and electrons.
The Global Argon Dark Matter Collaboration (GADMC) is undertaking an
ambitious global program from the extraction and purification of
Underground Argon (UAr), depleted in 39Ar which reduces the internal
background, to the development of $25 cm^2$ Silicon Photo Multiplier
(SiPM) modules capable of resolving single photoelectrons.
DarkSide-20k is the next stage of this program and will be the next
generation dual phase Argon TPC. DarkSide-20k will be housed in the
Gran Sasso underground laboratory (LNGS) and has an exposure goal of
~100 tonne-years with zero instrumental background in expectation of a
WIMP-nucleon cross section of $10^{-47} cm^2$ for a WIMP mass of 1TeV/$c^2$
during a 5-year run. An overview of the DarkSide experimental program
will be presented with a focus on the upcoming DarkSide-20k detector
and the new technologies involved.
