Description
The Global Argon Dark Matter Collaboration (GADMC) will pursue a sequence of future LAr dual phase TPC detectors to search for WIMPs with sensitivity that surpasses current level by several orders of magnitude, due to LAr technology excellent potential. The first detector in the sequence is the DarkSide-20k two-phase detector, that is getting ready for construction at LNGS. DarkSide-20k will have ultra-low backgrounds and sensitivity to WIMP-nucleon cross sections down to 1.2 x 10^{-47} cm^2 for WIMPs of 1 TeV/c^2 mass with a LAr exposure of 100 t yr. GADMC will also pursue WIMP search below 10 GeV/c^2, by looking for the electroluminescence signal, with another smaller detector developed in parallel, referred to as DarkSide-LowMass and installed at LNGS. This dedicated search will have excellent discovery capability, reaching the so-called neutrino floor in the low-mass search region. A subsequent objective will be the construction of the ARGO detector which will achieve a LAr exposure of 1000 t yr to push the sensitivity to the neutrino floor region for high mass WIMPs. The combination of the three experiments will cover the WIMP hypothesis down to the neutrino floor for masses from 1 GeV/c^2 to several hundreds of TeV/c^2.
