Results from KASCADE–Grande

The KASCADE–Grande experiment, located at Karlsruhe Institute of Technology (Germany) is a multi-component extensive air-shower experiment devoted to the study of cosmic rays and their interactions at primary energies 1014–1018 eV. Main goals of the experiment are the measurement of the all-particle energy spectrum and mass composition in the 1016–1018 eV range by sampling charged (Nch) and muon (NμNμ) components of the air shower. The method to derive the energy spectrum and its uncertainties, as well as the implications of the obtained result, is discussed. An overview of the analyses performed by KASCADE–Grande to derive the mass composition of the measured high-energy comic rays is presented as well.
