“…The relevant components of the KASCADE-Grande (Apel et al, 2010) multi-detector experiment used for the present analysis are the Grande and KASCADE arrays. Grande is formed by 37 stations of 10 m 2 scintillation detectors each, spread over an irregular grid with an average spacing of $137 m, covering an area of about 700 Â 700 m 2 (see Fig.…”

“…Also in this case the total number of muons N l in the shower disk is derived from a maximum likelihood estimation where the lateral distribution function is based on the one proposed by Lagutin and Raikin (2001). The reconstruction procedures and accuracies of KASCADE-Grande observables are described in detail in Apel et al (2010) and related references therein.…”

Previous results obtained by KASCADE-Grande using the QGSjetII-02 hadronic interaction model have shown that the energy spectrum of cosmic rays between 10 16 eV and 10 18 eV exhibits a significant hardening at approximately 2 Â 10 16 eV and a slight but statistically significant steepening close to 10 17 eV. Moreover, the analysis with QGSjetII-02 suggests that the break observed around 10 17 eV is caused by the heavy component of primary cosmic rays. In this paper, we report on the results of similar analyses performed using the SIBYLL 2.1 and EPOS 1.99 hadronic interaction models to interpret the data. The present results confirm qualitatively the previous findings. However, the intensity of the all-particle spectrum, the positions of the hardening and steepening of the spectrum, as well as the relative abundance of the heavy and light mass groups depend on the hadronic interaction model used to interpret the data.

The joint measurements with the KASCADE muon tracking devices are ensured by an additional cluster (Piccolo) located close to the center of KASCADE-Grande and deployed for fast trigger purposes.…”

a b s t r a c tThe KASCADE-Grande experiment operated at 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, with a high resolution, the total number of charged particles (N ch ) and of muons (N μ ). In this contribution we present the latest results about:(i) The measurement of the all particle energy spectrum, discussing the influence of the hadronic interaction model used to derive the energy calibration of the experimental data. (ii) The energy spectra derived separating the events according to the N μ =N ch ratio. This technique allowed us to unveil a steepening of the spectrum of heavy primaries at E $ 10 16:92 7 0:04 eV and a hardening of the spectrum of light primaries at E $ 10 17:08 7 0:08 eV.(iii) The elemental spectra (for five mass groups) obtained applying a detailed unfolding analysis technique.(iv) A search for large scale anisotropies.

“…In parallel to the N µ − N ch energy and mass estimation procedure used in the KASCADEGrande Experiment [1], the study of the lateral density of charged secondary particles from an EAS can provide sufficient information in order to be used in the development of an alternative reconstruction method. From the analysis of CORSIKA [2] EAS simulations based on the QGSJet-II.02 hadronic interaction model, the charged particle densities at 500 m (S(500) parameter [3]) and 200 m (S(200) parameter [4,5]) from the shower core, were proven to be good candidates for energy estimation and mass discrimination.…”

In previous studies based on CORSIKA EAS simulations with the QGSJet-II-02 hadronic interaction model, the observables S(200) and S(500) (the charged particle densities at 200 m and 500 m from the shower axis) were found to be good candidates for mass discrimination and energy estimation. In order to study the effects of new hadronic interaction models on the reconstruction of EAS from the KASCADE-Grande experiment, a set of CORSIKA simulated showers was computed using the QGSJet-II.04 and EPOS-LHC models. Lateral Energy Correction Functions (LECF) are obtained for the Grande array using a Geant4 simulation code containing a realistic geometry of the Grande station. The LECFs are used to reconstruct the charged particle densities from the energy deposits in the Grande stations. We are using the real and reconstructed lateral distributions of charged particles in order to find corresponding observables for mass discrimination and energy estimation.
