Description

MIMAC is a project of directonal direct detection of non-baryonic dark matter using a matrix of micro-tpc chambers with a 3D reconstruction of recoil tracks. The directionality degree of freedom opens the possibility to reject the background efficiently by its isotropic spatial distribution as it has been shown in our recent papers (J.Billard et al.). The 3D reconstruction is possible due to the MIMAC electronics developed in the last three years coupled to a specially designed pixelized micromegas. The first recoil tracks in 3D produced by neutrons of a few tens of keV will be presented. The very low energy threshold (~300 eV) and the fast read-out give access to the head-tail detection. The exclusion plot of the final detector (50m3) will be presented showing the allowed SUSY model region to be explored.
