Description

In case dark matter consists of hidden-sector photons which kinetically mix with regular photons, a tiny oscillating electric-field component is present wherever we have dark matter. In the surface of conducting materials this induces a small amount of radiation being emitted almost perpendicular to the surface, with the corresponding photon frequency approximately matching the mass of the hidden photons. We report on a construction of an experimental setup with a large 15 m$^2$ spherical metallic mirror that will allow for searches of hidden-photon dark matter in the eV and sub-eV range by application of different electromagnetic radiation detectors. We discuss sensitivity and accessible regions in the dark matter parameter space.
