  MACHe3 (MAtrix of Cells of superfluid Helium 3) is a project of non-baryonic
Dark Matter search using superfluid He3 as sensitive medium. Simulations on a
high granularity matrix show very good rejection against background events.
First results on a prototype cell are very encouraging. Neutron detection has
been highlighted as well as cosmic muon detection. A phenomenological study has
been done with the DarkSUSY code to investigate complementarity of MACHe3 with
existing Dark Matter detectors.
