Measurement of electromagnetic and TEV muon components of extensive air showers by eas-top and MACRO experiments

Abstract The simultaneous observation of the electromagnetic and TeV muon components of extensive air showers by the EAS-TOP and MACRO detectors, respectively, is described for a period of 100 days in 1990. The two detectors and their combined resolutions are briefly reviewed and muon multiplicity distributions for various detector configurations are presented. A first analysis of the physical parameters N μ and N e related to the study of the primary composition at E ν = 10 14 − 10 16 eV is also presented.
