Investigating the 2 knee: The KASCADE-Grande experiment

Recent results from the multi-detector set-up KASCADE on measurements of cosmic rays in the energy range of the so called ”first” knee (at ≈ 3PeV) indicate a distinct knee in the energy spectra of light primary cosmic rays and an increasing dominance of heavy ones towards higher energies. This leads to the expectation of knee-like features of the heavy primaries at around 100 PeV. To investigat...

Energy spectrum and elemental composition of cosmic rays in the PeV region Recent results and future prospects of the KASCADE experiment

KASCADE (KArlsruhe Shower Core and Array DEtector) is determining flux spectra for different primary mass groups to disentangle the knee feature of the primary cosmic-ray energy spectrum. The energy spectra of the light element groups result in a knee-like bending and a steepening above the knee. The topology of the individual knee positions suggests a rigidity dependence. To proof the rigidity...

KASCADE extensive air shower experiment

The main aim of the KASCADE extensive air shower (EAS) experiment is the determination of the chemical composition of cosmic rays in the energy range around and above the knee at Ek ≈ 3 PeV. A large number of observables is measured simultaneously for each individual event, by the combination of various detection techniques for the electromagnetic, the muonic, and the hadronic component of the ...

KASCADE-Grande: a conclusive experiment on the knee

We present the status and capabilities of the Extensive Air Shower experiment (KASCADE-Grande) which is being realized at Forschungszentrum Karlsruhe through a large collecting area (0.5 km) electromagnetic array (Grande) that will operate jointly with the existing KASCADE detectors. KASCADE-Grande will cover the primary energy range 10 eV < E0 < 10 eV, overlapping with KASCADE around 10 eV, th...

Energy Spectra of Elemental Groups of Cosmic Rays: Update on the KASCADE Unfolding Analysis

The KASCADE experiment measures extensive air showers induced by cosmic rays in the energy range around the so-called knee. The data of KASCADE have been used in a composition analysis showing the knee at 3–5 PeV to be caused by a steepening in the light-element spectra [1]. Since the applied unfolding analysis depends crucially on simulations of air showers, different high energy hadronic inte...
