URAGAN is a wide-aperture precision muon hodoscope located in Moscow, Russia, 55.7$^\circ$ N, 37.7$^\circ$ E, 173 m a.s.l. It allows to obtain the angular distribution of the muon flux. This distribution may be characterized by a vector of local anisotropy (the sum of the vectors of the particle arrival directions, normalized to the total number of muons). It was shown earlier that annual...

Investigations of cosmic rays on the surface of the Earth allow to derive information of applied character on the conditions of the interplanetary magnetic field and of the geomagnetic field. For this purpose, it is necessary to collate the trajectories of the particles detected in the ground detector to trajectories of primary cosmic rays in the heliosphere. This problem is solved by means of...

Study of the energy characteristics of EAS muon component with an increase the primary particle energy can be a key to solving the "muon puzzle" – the problem of muon excess in EAS observed in several experiments.
Such investigations are currently being conducted in the NEVOD-DECOR experiment on detection of inclined muon bundles. Cherenkov water detector NEVOD measures the energy deposit of...

The results of the long-term investigations of very high energy extensive air showers with the calibration telescope system (CTS) are presented. The CTS setup is a part of the NEVOD experimental complex. Its top plane is used to register the electron EAS component in the primary particle energy range of 10^14–10^15 eV, while the bottom plane can register muon component in the primary energy...

The description of the NEVOD detector multi-level system of trigger signal formation created for on-line selection of events is presented. The first level forms signals of three types for each quasispherical module (QSM) and provides registration of events with one or several photomultipliers. The second level represents a coincidence circuit of triggers from QSM clusters. This level is based...

In MEPhI, the URAN array for registration of the neutron component of extensive air showers (EAS) is being created. The setup has a cluster structure and includes 6 clusters of 12 detectors each, located on the roofs of the buildings. En-detectors capable of simultaneous registration of two main EAS components are used: electromagnetic (e) and neutron (n). The recording system of the setup...

The more accurate original calculations of the atmospheric vertical energy spectrum at energies $10^{2} - 10^{5} \space $ GeV have been carried out in terms of DPMJET $~2.55 \space $ and VENUS $~4.12 \space $ models. The Gaisser-Honda approximation and results of measurements of energy of primary protons, helium and nitrogen nuclei has been used. The package CORSIKA $~7.4 \space $ has been...

The TAIGA Observatory is aimed to provide the study of gamma-rays of high energies (above 100 TeV) and cosmic rays with energies higher than 10 PeV. The main advantage of the observatory is a hybrid method of detection of EAS generated by gamma rayswith an array of wide-angle detectors of Cherenkov radiation of EAS and by the network of IACT.
In the report the features of design of the...
