Abstract: The KASCADE-Grande experiment measures extensive air showers induced by cosmic rays in the knee region (with energies between 0.5 PeV and 1 EeV). The principal task of the experiment is to measure precisely the energy and chemical composition of primary cosmic rays to clarify the origin of the knee. The data of the original KASCADE experiment have been used in a composition analysis, which shows the knee is caused by a steepening of the element spectra. The limitations to these conclusions due to the dependence on the high energy hadronic interaction models used in the simulations are also presented. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
