XENON1T, the first tonne-scale dual-phase xenon time projection chamber, took data at the Laboratori Nazionali del Gran Sasso in Italy between 2016 and 2018. The experiment was sensitive to the scattering of weakly interacting massive particle (WIMP) dark matter within a 2 t target volume. By using both the scintillation and ionisation signals induced by an interaction it is possible to discriminate WIMP-induced events from the main electronic recoil background. The electronic-recoil background rate of 82 ev / (t yr keV) is the lowest ever achieved in such a detector.
Work is now underway to upgrade the detector to XENONnT. Using much of the same infrastructure, this will have a three-times larger target. At the same time XENONnT will have a significantly reduced background rate, largely due to a new radon distillation column.
This talk will present the latest results from XENON1T as well as the status of the XENONnT work currently being performed.
