Description
The Muon Tracking Detector (MTD) in KASCADE-Grande experiment measures with
high accuracy muon directions in EAS (Emu>800MeV). In addition, shower
directions are determined by the surface detectors with high precision. These
two conditions allow to study shower longitudinal development by means of
quantities like muon production heights and muon pseudorapidities and
lateral distributions of muon densities. Results of such investigations
will be shown between 10^15 eV and 10^17 eV, for data and simulations
based on CORSIKA with QGSJetII+Fluka2002.4 model combination and the new EPOS
version 1.99. The muon pseudorapidity distributions will be studied in the
predefined distance range to the shower core and compared to the
simulations as well.The pseudorapidity distributions for muons which stem
from above 15 km muon production height and which stem very likely from the
first interactions are studied in more detail also in the context of
geometric scaling in the near LHC energy range.
