TIME-TRACK COMPLEMENTARITY APPROACH FOR THE STUDY OF THE EAS LONGITUDINAL DEVELOPMENT

The possibility of using muon tracking and timing measurements for the reconstruction of the EAS hadron longitudinal-development in the knee energy region is discussed. Simulation results are presented which in dicate that, provided these measurements are used as complementary and with reasonable TTC ('time-track complementarity') selection, the acc uracy of the muon production height reconstruction is sufficiently goo d even for sub-GeV energy muons, observed at sea level. Possible appli cations and advantages of the TTC approach in the study of primary cos mic rays and high-energy interactions are discussed.
