Mimac-He3, a Project for a Micro-TPC Matrix of Chambers of Helium 3 for Axial Direct Detection of Non-Baryonic Dark Matter

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.
