Description

The XENON100 dark matter experiment, installed in the Laboratory Nazionali del Gran Sasso (LNGS, Italy), is searching for WIMP dark matter particles scattering off a 62 kg liquid xenon target in a dual phase (liquid/gas) time projection chamber. Careful material selection, a novel detector design, and an upgrade of the passive shield, together with capitalizing the self-shielding power of liquid xenon, are crucial in order to achieve a background of less than 0.01 events/kg/keV/day in the fiducial volume. This background, which has been verified experimentally, is lower than in any other dark matter experiment In this talk, I will present the experiment and its status, details about the detector calibration, and focus on recent analyses and results.
