New detecting system of the NEVOD Cherenkov water detector

A new detecting system of the NEVOD Cherenkov water detector is described, whose development implies replacement of photomultipliers in quasispherical modules of the existing three-dimensional network by low-noise FEU-200 photomultipliers, their dynamic range expansion with the purpose to study events with energies above 1017 eV, the transition to the cluster structure principle, and the possibility of operating in the hodoscopic mode.
