Abstract:
"In previous investigations at KASCADE-Grande a Monte Carlo simulation code based on GEANT3 has been developed to describe the energy deposited by EAS particles in the detector stations. In an attempt to decrease the simulation time and insure compatibility with the geometry description in standard KASCADE-Grande analysis software, several structural elements have been neglected in the implementation of the Grande station geometry. Lately, in order to close the gap between simulated and experimental data for the KASCADE-Grande experiment, a more accurate simulation of the Grande detector response was necessary. A new simulation code was written based on the newer Geant4 toolkit, including a realistic geometry of the detector station with structural elements that were not considered in previous studies (and even a layer of soil below the detector hut!). We present a comparison between the results obtained with the Geant4-based code with a realistic implementation of the detector geometry and the results obtained previously with the GEANT3-based code using a simplified geometry. We expect that the new simulation code will allow us to build more accurate lateral energy correction functions for the reconstruction of EAS events."
