Directional detection of galactic dark matter is a Dark Matter search strategy. It takes advantage of the rotation of the Solar system around the galactic center through the Dark Matter halo, and allows to show a direction dependence of WIMP events. This may be a powerful tool to identify genuine WIMP events as such.
Directional detection strategy requires the simultaneous measurement of the energy and the 3D track of low energy recoils, which is a common challenge for all current projects of directional detectors.
