MIMAC: A large micro-tpc for directional non-baryonic dark matter search (15'+5')
 
A Micro-tpc MAtrix of Chambers of 3He and 19F  is proposed as a directional 
detector
for non-baryonic dark matter search. The purpose is to exploit the axial 
interaction
of WIMPs with neutron (3He) and proton (19F) with a electron-recoil 
discrimination by
the dual track-ionization detection. The complementary aspect of this axial 
detection
with respect to the scalar one will be illustrated. In order to read-out the
pixelized anode a dedicated electronics  has been developped. The response of 
the
first prototype of one of the micro-tpc chamber as well as the first measurement 
of
ionization quenching factor in 4He at low energies (1 to 50 keV)  will be 
presented.
