  MACHe3 (MAtrix of Cells of superfluid He3) is a project of a new detector for
direct Dark Matter (DM) search, using superfluid as a sensitive medium. An
experiment on a prototype cell has been performed and the first results
reported here are encouraging to develop of a multicell prototype. In order to
investigate the discovery potential of MACHe3, and its complementarity with
other DM detectors, a phenomenological study done with the DarkSUSY code is
shown.
