Description
The XMASS experiment, proposed as a multi-purpose underground
detector using liquid xenon, is now constructing an 800 kg
xenon detector in the Kamioka mine in Japan. The detector is
designed especially to search for WIMP dark matter candidates.
The main feature of the detector to reduce gamma ray backgrounds
is the self-shielding effect of liquid xenon. In addition,
the detector is located in a water tank to reduce incoming neutron
backgrounds. The background event rate is expected to be as low as
1e-4 count/day/kg/keVee. The characteristics of the experiment
and the sensitivity to WIMP dark matter are presented.
