The XENONnT Dark Matter Search Experiment

ORAL

Abstract

XENON1T, the largest and most sensitive dark matter direct detection experiment, has set the most stringent upper limit on the spin-independent WIMP-nucleon cross section, with a minimum of 4.1 × 10-47 cm2 for a 30 GeV/c2 WIMP. The next step in the XENON program, XENONnT, is now under construction at LNGS. With this upgrade, the XENON collaboration aims to probe spin-independent WIMP-nucleon cross sections as low as 2 × 10-48 cm2 with a 20 tonne-year exposure, using a 6 tonne sensitive target with backgrounds from 222Rn and neutrons reduced by an order of magnitude. This talk will give an overview of the XENONnT detector, and discuss improvements to the existing XENON1T infrastructure that will make this next generation of the XENON program possible.
