Abstract
A search for hidden-photon (HP) dark matter using a multi-cathode counter is reported. The technique based on counting of single electrons emitted from outer cathode of the proportional counter by hidden-photons was used. The apparatus and the calibration of the counter by ultraviolet lamp are described. It is shown that this technique attains a maximum sensitivity in the energy range of Vacuum Ultraviolet. From the results of measurements we set an upper limit on the photon-HP mixing parameter η. A further progress of using a multicathode technique is discussed.
