Search for hidden photons of cold dark matter using a multi-cathode counter
The purpose of the experiment is to record a very specific process: the conversion of a hidden photon into an electron emitted from the surface of the metal. In this case, the target for hidden photons is the free electrons of the degenerate electron gas of the metal, and the effect is proportional to the area of the cathode. Currently, strong limitations have been obtained using detectors where the working volume is the detector volume, but the target in this case is the valence electrons of the target atoms. Obviously, these are completely different elementary processes. Currently, our detector is the only operational detector sensitive to the interaction of hidden photons with free electrons of the degenerate electron gas of a metal.
