`Time-track complementarity' approach for the study of the EAS longitudinal development

Abstract

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 indicate that, provided these measurements are used as complementary and with reasonable TTC (`time-track complementarity') selection, the accuracy of the muon production height reconstruction is sufficiently good even for sub-GeV energy muons, observed at sea level. Possible applications and advantages of the TTC approach in the study of primary cosmic rays and high-energy interactions are discussed.
