The Calibration Telescope System of the NEVOD Cherenkov Water Detector

Abstract

The calibration telescope system of the NEVOD Cherenkov water detector is described. Scintillation counters are used in the setup as detecting elements. The detection system is equipped with logical and amplitude channels and provides the calibration of the Cherenkov water detector. It can also be used to investigate the electron and muon components of an extensive air shower. A method for amplitude calibration of the scintillation counters is described, with which it is possible to estimate the number of detected charged particles. The results for the 1.5-year operation of the setup as a detector of extensive air showers are presented.
