  DARWIN (dark matter wimp search with noble liquids) is a design study for a
next-generation, multi-ton dark matter detector in Europe. Liquid argon and/or
liquid xenon are the target media for the direct detection of dark matter
candidates in the form of weakly interacting massive particles (WIMPs). Light
and charge signals created by particle interactions in the active detector
volume are observed via the time projection chamber technique. DARWIN is to
probe the spin-independent, WIMP-nucleon cross section down 1e-48 cm2 and to
measure WIMP-induced nuclear recoil spectra with high-statistics, should they
be discovered by an existing or near-future experiment. After a brief
introduction, I will describe the project, selected R&D topics, expected
backgrounds and the physics reach.
