Simulations on a high granularity matrix show very good rejection against background events. First results on a prototype cell are very encouraging. Neutron detection has been highlighted as well as cosmic muon detection. A phenomenological study has been done with the DarkSUSY code to investigate complementarity of MACHe3 with existing Dark Matter detectors.5 pages, 5 figures, to appear in Proceedings of the 4th Marseille International Cosmology ConferenceAstrophysicstext
