XENON100 is a liquid xenon time projection chamber built to search for rare collisions of hypothetical, weakly interacting massive particles (WIMPs), which are candidates for the dark matter in our universe, with xenon atoms. Operated in a low-background shield at the Gran Sasso Underground Laboratory in Italy, XENON100 has reached the unprecedented background level of <0.15 events/(day keV) in the energy range below 100 keV in 30 kg of target mass, before electronic/nuclear recoil discrimination. It found no evidence for WIMPs during a dark matter run lasting for 100.9 live days in 2010, excluding with 90% confidence scalar WIMP-nucleon cross sections above 7e-45 cm2 at a WIMP mass of 50 GeV/c2. A new run started in March 2011, and more than 210 live days of WIMP-search data were acquired. Results are expected to be released in spring 2012. The construction of the ton-scale XENON1T detector in Hall B of the Gran Sasso Laboratory will start in late 2012.
