Description
Summary:The results of the long-term investigations of very high energy extensive air showers with the calibration telescope system of the NEVOD experimental complex are presented. The top plane of the setup is used to register the electron EAS component in the primary particle energy range of 1014−1015 eV, while the bottom plane can register muon component in the primary energy range of 1016−1018 eV. Two independent reconstruction methods of the charged particle local density spectrum are considered. The effects of building construction and water pool on the measurement results were calculated using Geant4. The exponents of charged particles local density spectra are obtained for different energy ranges, and the presence of the second "knee" in the spectrum of the EAS muon component is confirmed. The results are compared with CORSIKA-based calculations and data from other setups.
