Description
Measurements of the energy spectra of cascade showers generated due to interactions of penetrating cosmic ray particles in massive water/ice detectors is one of the main methods of the study of the energy characteristics of the fluxes of muons and neutrinos. In the present paper, results of investigations of cascades initiated by inclined muons in the Cherenkov water detector NEVOD with a volume of 2000 m^3, located at the ground surface and equipped with a spatial lattice of 91 quasi-spherical modules (QSMs), detecting Cherenkov light from any direction with nearly equal efficiency, are discussed. A brief description of the setup features is given. The approaches to the reconstruction of energy and spatial parameters of the showers registered in a dense lattice of QSMs, and questions of the absolute calibration of the QSM response are considered. Preliminary results of the measurements of the energy spectrum of the cascades in the energy range 30 GeV – 10 TeV based on the data accumulated in 2013 – 2015 experimental series (about 11,000 live observation time) and their comparison with expectation for some models of the muon energy spectrum are presented.
