Description
The Global Argon Dark Matter Collaboration (GADMC), formed to unite liquid argon–based dark matter experiments, is currently constructing its next-generation experiment DarkSide-20k. Located at the Laboratori Nazionali del Gran Sasso (LNGS), DarkSide-20k builds upon the success of previous argon experiments, including its predecessor, DarkSide-50, to continue the search for weakly interacting massive particles (WIMPs). The experiment introduces several new technologies and design improvements to reduce backgrounds and enhance sensitivity.
With its large target mass and advanced instrumentation, DarkSide-20k is expected to probe WIMP–nucleon cross sections below 1×10^(-42) " " 〖"cm" 〗^2 for WIMP masses above 800 MeV. Central to this sensitivity is the use of a dual-phase time projection chamber (TPC), which enables precise reconstruction of particle interactions through the detection of both primary scintillation light and an amplified secondary electroluminescence signal. While this amplification improves sensitivity to low-energy nuclear recoils, it also renders DarkSide-20k sensitive to coherent elastic neutrino nucleus scattering (CEνNS). This sensitivity opens a complementary physics program beyond dark matter searches, including the potential detection of neutrinos from core-collapse supernovae within our galaxy. As such, DarkSide-20k serves not only as a powerful probe of dark matter but also as a novel observatory for low-energy neutrino physics.
