TL;DR: In this paper, a composition analysis of KASCADE air shower data is performed by means of unfolding the two-dimensional frequency spectrum of electron and muon numbers, and the analysis is the determination of energy spectra for elemental groups representing the chemical composition of primary cosmic rays.

TL;DR: The results show that it should be possible to determine the nature and composition of UHECRs with combined radio and particle detectors, and to detect the ultrahigh-energy neutrinos expected from flavour mixing.

TL;DR: In this article, the KASCADE-Grande air-shower data was used to reconstruct the energy spectra of different mass groups by unfolding methods over an energy range where the detector is fully efficient.
