Abstract

We report on a new technique of a Multi-Cathode Counter (MCC) developed to search for hidden photon (HP) cold dark matter (CDM) with a mass from 5 to 10 eV. The method suggested in the assumption that hidden photons of the mass greater than a work function of the metal, the cathode of the counter is fabricated induce emission of single electrons from a cathode. Three configurations of the same counter are used to measure the count rates R1, R2 and R3 of the single electron events sequentially each week, where the difference R1- R2 measures the effect from HP and R3 is used as a reference sequence to monitor the counting process. At present the work is aimed to refine the procedure of data treatment and to look for long term variations which should be accounted for in the final analysis of data.
