Previous results obtained by KASCADE-Grande using the QGSjetII-02 hadronic interaction model have shown that the energy spectrum of cosmic rays between 1016eV and 1018eV exhibits a significant hardening at approximately 2×1016eV and a slight but statistically significant steepening close to 1017eV. Moreover, the analysis with QGSjetII-02 suggests that the break observed around 1017eV is caused by...
The energy spectrum of cosmic rays between 10 16 eV and 10 18 eV, derived from measurements of the shower size (total number of charged particles) and the total muon number of extensive air showers by the KASCADE-Grande experiment, is described. The resulting all-particle energy spectrum exhibits strong hints for a hardening of the spectrum at approximately 2·10 16 eV and a...
LOPES is set up at the location of the KASCADE-Grande extensive air shower experiment in Karlsruhe, Germany and aims to measure and investigate radio pulses from extensive air showers. Since radio waves suffer very little attenuation, radio measurements allow the detection of very distant or highly inclined showers. These waves can be recorded day and night, and provide a bolometric measure of the...
