Description
Large arrays of aligned carbon nanotubes (CNTs) could be used as target material for directional detection of weakly interacting dark matter particles (WIMPs). Specifically, if a WIMP scatters on the surface of a CNT, a carbon ion might be ejected and propagate through multiple collisions in the CNT lattice. If the ion initial energy is large enough, to compensate energy losses along its path, and its direction sufficiently aligned with the CNT axis, the ion might reach the CNT upper end. There, it might be detected and provide informations on the galactic WIMP wind direction.
