Direct dark-matter searches are promising techniques to identify the nature of dark-matter particles via their elastic scattering off target nuclei. The directional information allows to extend dark-matter searches beyond the neutrino floor, providing an unambiguous signature of galactic dark matter. The new experiment NEWSdm (Nuclear Emulsions for WIMP Search-directional measurement) is based on the technology of nuclear emulsions, which combine high spatial resolution and the possibility of creating a large, solid, mass detector, acting both as target and tracking device. The detector will be placed on an equatorial telescope in order to cancel out the effect of the Earth rotation, keeping the detector at a fixed orientation toward the expected direction of galactic WIMPs.
