First detection of tracks of radon progeny recoils by MIMAC

Understand

The MIMAC experiment is a $\mu$-TPC matrix project for directional dark matter search.

• Directional detection is a strategy based on the measurement of the WIMP flux anisotropy due to the solar system motion with respect to the dark matter halo.
• The main purpose of MIMAC project is the measurement of the energy and the direction of nuclear recoils in 3D produced by elastic scattering of WIMPs.
• Since June 2012 a bi-chamber prototype is operating at the Modane underground laboratory.
