Directional detection of galactic Dark Matter
Résumé
MIMAC is a project of micro-TPC matrix of gaseous chambers (helium, CF4 ...) for direct detection of non-baryonic dark matter. Measurement of both track and ionization energy will allow the electron-recoil discrimination, while access to the directionnality of the tracks will open a unique way to distinguish a geniune WIMP signal from any background. Firsts results of low energy events (electron, nuclear recoils) will be presented together with the expected performances of the directional detector
