Resumen:
For the experimental conditions of the KASCADE-Grande experiment, the density of charged particles of large air showers (EAS) at the distance of about 500 m from the shower core S(500) has been shown by detailed simulation studies to be an approximate energy estimator, being nearly independent of the mass of the primary particle. This report presents some first experimentally observed features of the S(500) observable of EAS registered with the KASCADE-Grande array installed at the Forschungszentrum Karlsruhe, Germany. The measured energy deposits of particles in the 37 scintillation detector stations have been used to reconstruct the lateral charged particle distributions which are described by a Linsley LDF. With adjusting the charged particle density distribution and applying various cuts, the S(500) distribution of the data has been evaluated. Among other features, the S(500) dependence from the EAS angle of incidence has been studied.
