The MIMAC project is a multi-chamber detector for Dark Matter search, aiming at measuring both track and ionisation 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. Reconstruction of track of alpha from Radon impurities is shown as a first proof of concept.
