TL;DR
This paper presents the analysis of cosmic ray composition in the 10^15 to 10^18 eV range using Tunka Array data, highlighting recent results and future research prospects.
Contribution
It provides the final analysis of X_max distribution from Tunka-25 data and discusses future measurements with the larger Tunka-133 array.
Findings
X_max distribution analyzed for 3×10^15 to 3×10^16 eV energy range
Results indicate composition trends across the studied energy spectrum
Future plans include extending measurements up to 10^18 eV with Tunka-133
Abstract
The final analysis of the Extensive Air Shower (EAS) maximum X_max depth distribution derived from the data of Tunka-25 atmospheric Cherenkov light array in the energy range 3.10^15 - 3.10^16 eV is presented. The perspectives of X_max studies with the new Cherenkov light array Tunka-133 of 1 km^2 area, extending the measurements up to 10^18 eV, are discussed.
