  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 500
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 during several weeks. As a measure of the
effect from HP the difference R1-(R2-D3/D2xR3) has been used. Some preliminary
results have been obtained on a first try to search for HP with a mass from 5
to 500 eV. The upper limit for mixing parameter X has been set on the level of
3.3x10-10 for hidden photon mass from 9 to 100 eV. In our plans is to refine
the procedure of data treatment and to continue the measurements to collect
more data.
