Abstract :
We present the main results of the Extensive Air Shower Cherenkov array Tunka-25. They cover the energy spectrum from 8 · 1014 to 1017 eV and mass composition of primary cosmic rays in the energy range of 3·1015 − 3 · 1016 eV. A new lateral distribution function (LDF) of Air Shower Cherenkov light and a new method to analyze the maximum depth distribution of the shower have been developed. Both have been successfully applied in the data analysis of Tunka-25. We also discuss methods of time and amplitude calibration of the array, providing an accurate determination of the primary energy and the steepness of the LDF.
