Abstract
The KASCADE-Grande experiment operated at KIT from January 2004 to November 2012, measuring EAS generated by primary cosmic rays in the 1016–1018eV energy range. The experiment detected, for each single event, with a high resolution, the total number of charged particles (Nch) and of muons (Nμ).In this contribution we present the latest results about:(i)The measurement of the all particle energy spectrum, discussing the influence of the hadronic interaction model used to derive the energy calibration of the experimental data.(ii)The energy spectra derived separating the events according to the Nμ/Nch ratio. This technique allowed us to unveil a steepening of the spectrum of heavy primaries at E~1016.92±0.04eV and a hardening of the spectrum of light primaries at E~1017.08±0.08eV.(iii)The elemental spectra (for five mass groups) obtained applying a detailed unfolding analysis technique.(iv)A search for large scale anisotropies.
