Time Distributions of Electromagnetic and Hadronic Components in Giant EAS

From our databank of giant air showers produced by 4D simulation with CORSIKA, we have derived the time distributions for photons, electrons, muons, charged hadrons and neutrons. Those distributions are compared at different distances from the shower core up to 2 km for proton and iron induced cascades. The average arrival time at different distances can help the reconstruction of the axis position and we present some cases of axis determination at 20 m from the actual location in the case of AUGER experiment.
