“…At moderate zenith angles (less than 55°), a residual contribution of electromagnetic and hadron EAS components to the response of the unscreened water calorimeter located at the surface is observed. This contribution decreases nearly exponentially with the slant depth of the atmosphere [11], and at large zenith angles practically only muons and secondary relative to them particles remain in the bundle events. Arrows in the lower part of the figure indicate typical energies (calculated meanlogarithmic values [4]) of primary particles contributing to muon bundle formation at different zenith angles.…”

“…Detection of muon bundles in a wide range of multiplicities and zenith angles provides a possibility of exploration of a very wide interval of primary energies in frames of a single experiment. Preliminary results of the measurements of muon bundle energy deposit were reported at the preceding conference [11]. For the moment, the available experimental statistics has been increased about 1.7 times and is now based on 29,175 h of net observation time.…”

In order to solve the problem of the excess of multi-muon events observed in several cosmic ray experiments at ultra-high energies (so-called 'muon puzzle'), investigations of the energy characteristics of the muon component of extensive air showers (EAS) are required. A possible approach to such investigations is the measurement of the energy deposit of muon bundles in the detector, which provides information on the mean muon energy. In the experiment being now conducted at the NEVOD-DECOR complex, the local muon density and EAS arrival direction are determined according to the data of the coordinate-tracking detector DECOR, whereas the energy deposit is measured by means of the Cherenkov water calorimeter NEWOD. Simultaneous detection of muon bundles in a wide range of zenith angles and muon multiplicities ensures exploration of primary particle energy region of 10 16 -10 18 eV and even higher. Results of the measurements of the energy deposit of the inclined muon bundles at various zenith angles based on the data accumulated during more than 29,000 h observations over the period from May 2012 to February 2017 are presented and compared with simulations performed by means of the CORSIKA program.

The Tunka Radio Extension (Tunka-Rex) is a digital radio array operating in the frequency band of 30-80 MHz and detecting radio emission from air-showers produced by cosmic rays with energies above 100 PeV. The experiment is installed at the site of the TAIGA (Tunka Advanced Instrument for cosmic rays and Gamma Astronomy) observatory and performs joint measurements with the co-located particle and air-Cherenkov detectors in passive mode receiving a trigger from the latter. Tunka-Rex collects data since 2012, and during the last five years went through several upgrades. As a result the density of the antenna field was increased by three times since its commission. In this contribution we present the latest results of Tunka-Rex experiment, particularly an updated analysis and efficiency study, which have been applied to the measurement of the mean shower maximum as a function of energy for cosmic rays of energies up to EeV. The future plans are also discussed: investigations towards an energy spectrum of cosmic rays with Tunka-Rex and their mass composition using a combination of Tunka-Rex data with muon measurements by the particle detector Tunka-Grande.
