Diurnal variations of the count rates from dark photons in PHELEX

Abstract

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