  MIMAC-He3 (MIcro-tpc MAtrix of Chambers of Helium 3) is a project for direct
detection of non-baryonic dark matter search using He3 as sensitive medium. The
priviledged properties of He3 are highlighted. The double detection :
ionization and track projection, is explained and rejection evaluated. A
phenomenological study in effective SUSY models has been to investigate the
MIMAC-He3 complementarity with respect to existing Dark Matter detectors.
