Dark Matter, Liquid Xenon

Scientific paper

The XENON10 Experiment is a dual (liquid/gas) phase time-projection chamber designed for direct detection of dark matter via elastic scattering of the Xe nuclei. It was deployed in March 2006 at LNGS (~ 3100 mwe) and is presently operational. The ratio of prompt (primary) scintillation to secondary scintillation (via electro-luminesence caused by ionization electrons extracted into the gas phase) allows event-by-event discrimination of electron and nuclear recoil events. A threshold < 10 keV nuclear recoil energy (keVr) is demonstrated, as well as a background rate of < 1 cts/kg/keVee/day (dru) before rejection. With 3-D position reconstruction (to define a fiducial region) and > 99% discrimination of gamma background (at 50% acceptance for nuclear recoils), XENON10 expects to be sensitive to a WIMP-nucleon interaction cross section of < 10-43 cm2 for WIMP particles with mass > 50 GeV.
