We describe the experiment PHELEX (PHoton-ELectron EXperiment) on the searchfor dark photons of cold dark matter using a technique of multi-cathode counterdeveloped by us for this task. We present the new data, the new upper limit forthe constant of kinetic mixing and also first results of measurements of thediurnal variations in solar and stellar frames. We outline the perspectives ofthis method for the search of dark photons

Diurnal variations of the count rates from dark photons in PHELEX
