  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.
