  The MIMAC project is a multi-chamber detector for Dark Matter search, aiming
at measuring both track and ionization with a matrix of micromegas micro-TPC
filled with He3 and CF4. Recent experimental results on the first measurements
of the Helium quenching factor at low energy (1 keV recoil) are presented,
together with the first simulation of the track reconstruction. Recontruction
of track of alpha from Radon impurities is shown as a first proof of concept.
