Abstract. KASCADE-Grande was an air-shower experiment designed to study cosmic rays between 10 16 and 10 18 eV. The instrument was located at the site of the Karlsruhe Institute of Technology, Germany at an altitude of 110 m a.s.l. and covered an area of 0.5 km 2 . KASCADE-Grande consisted of several detector systems dedicated to measure different components of the EAS generated by the primary cosmic rays, i.e., the muon and the electron contents of the air-shower. With such a number of EAS observables and the precision of the measurements, the KASCADE-Grande data can be used to not only study in detail the properties of cosmic rays but also to test the predictions of hadronic-interaction models. In this work, in particular, the attenuation lengths of the muon number and the charged number of particles of EAS in the atmosphere were extracted from the KASCADE-Grande data and the results were compared with the predictions of the new EPOS-LHC hadronic-interaction model.

“…This basic question in astroparticle physics still wait for a conclusive answer. Possible scenarios range from supernova remnants (SNR) [1], superbubbles [2] and magnetars [3] to cannonballs from supernovae [4] and the remnants of gamma-ray bursts in our galaxy [5], being the SNR model the most accepted paradigm. All these models have in common that they predict the existence of individual kneelike structures or breaks in the corresponding spectra of cosmic nuclei, which are associated with the efficiency of the accelerator or features of the particle propagation through the Galaxy.…”

Abstract. The detection of high-energy cosmic rays above a few hundred TeV is realized by the observation of extensive air-showers. By using the multi-detector setup of KASCADEGrande, and here in particular the detectors of the large Grande array, the energy spectrum and the elemental composition of high-energy cosmic rays in the energy range from 10 PeV to 1 EeV are investigated. The estimation of energy and mass of the high-energy primary particles is based on the combined analysis of the total number of charged particles and the total number of muons measured by the detector arrays of Grande and KASCADE, respectively. The latest analysis results have shown that in the all-particle spectrum two features are present: a hardening of the spectrum at energies around 20 PeV and a steepening, i.e. a knee-like structure, at 80-90 PeV. The latter one was found to be due to a decrease of flux of the heavy mass component.
