All-particle energy spectrum of KASCADE-Grande based on shower size and different hadronic interaction models
نویسندگان
چکیده
KASCADE-Grande is a large detector array for observations of the energy spectrum as well as the chemical composition of cosmic ray air showers up to primary energies of 1 EeV. The multi-detector arrangement allows to measure the electromagnetic and muonic components for individual air showers. In this analysis, the reconstruction of the all-particle energy spectrum is based on the size spectra of the charged particle component. The energy is calibrated by using Monte Carlo simulations performed with CORSIKA and high-energy interaction models QGSJet, EPOS and SIBYLL. In all cases FLUKA has been used as lowenergy interaction model. In this contribution the resulting spectra by means of different hadronic interaction models will be compared and discussed. 23rd European Cosmic Ray Symposium (and 32nd Russian Cosmic Ray Conference) IOP Publishing Journal of Physics: Conference Series 409 (2013) 012101 doi:10.1088/1742-6596/409/1/012101 Published under licence by IOP Publishing Ltd 1

Confronting the EPOS-LHC model predictions on the charged particle and muon attenuation lengths of EAS with the measurements of the KASCADE-Grande observatory
KASCADE-Grande was an air-shower experiment designed to study cosmic rays between 1016 and 1018 eV. The instrument was located at the site of the Karlsruhe Institute of Technology, Germany at an altitude of 110m a.s.l. and covered an area of 0.5 km. KASCADE-Grande consisted of several detector systems dedicated to measure different components of the EAS generated by the primary cosmic rays, i.e...
متن کاملKASCADE 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 is a multi detector setup for the investigation of extensive air showers in the 10 − 10 eV energy range. With the Grande array it is possible to reconstruct the shower core position, the arrival direction and the total number of charged particles in the shower. The Grande array measures in coincidence with the original KASCADE muon array consisting of 622 m shielded scintillators...

The KASCADE-Grande experiment has significantly contributed to the current knowledge about the energy spectrum and composition of cosmic rays for energies between the knee and the ankle. Meanwhile, post-LHC versions of the hadronic interaction models are available and used to interpret the entire data set of KASCADE-Grande. In addition, a new, combined analysis of both arrays, KASCADE and Grand...
متن کاملTest of Hadronic Interaction Models with the KASCADE Hadron Calorimeter
The interpretation of extensive air shower (EAS) measurements often requires the comparison with EAS simulations based on high-energy hadronic interaction models. These interaction models have to extrapolate into kinematical regions and energy ranges beyond the limit of present accelerators. Therefore, it is necessary to test whether these models are able to describe the EAS development in a co...
