Description

The KASCADE-Grande experiment operated in KIT from January 2004 to November 2012, measuring EAS generated by primary cosmic rays in the 10^16-10^18 eV energy range. The experiment detected, for each single event and with a high resolution, the total number of charged particles (Nch) and of muons (Nm). In this talk I will present the updated results about: - the measurement of the all particle energy spectrum, discussing the influence of the hadronic interaction model used in the event simulation. - The energy spectra derived separating the events according to the Nmu/Nch ratio. This technique allowed us to enhance the features of the heavy primary spectrum, measuring a change of slope at E~8x10^16 eV. - The elemental spectra (for five mass groups) obtained applying an unfolding analysis.
