Abstract
The Tunka-Grande experiment is a scintillation array with about 0.5 sq.km sensitive area at Tunka Valley, Siberia, for measuring charged particles and muons in extensive air showers (EASs). Tunka-Grande is optimized for cosmic ray studies in the energy range 10 PeV to about 1 EeV, where exploring the composition is of fundamental importance for understanding the transition from galactic to extragalactic origin of cosmic rays. This paper attempts to provide a synopsis of the current results of the experiment. In particular, the reconstruction of the all-particle energy spectrum in the range of 10 PeV to 1 EeV based on experimental data from four observation seasons is presented.

Blue circles - experiment data (Nµ and ρ200 are calculated from EAS events detected by Tunka-Grande array). Green circles - data of simulated Eass, initiated by gamma quantum. The events without any detected muons are plotted with l g(Nµ) = −1 to be
visible at the logarithmic axis. Lower red line indicates the selection criteria. "
