Abstract
In the energy region 10 - 100 TeV both the c.r. composition from direct mea surements and the cross section for high energy secondary production in the very forward region for p-air interactions are rather uncertain. Contempor aneous measurements of the total energy and of the threshold energy/nucleon of the primary particle can be provided by the atmospheric Cherenkov light and high energy muons. These measurements are performed by the combined op eration of the Cherenkov array of the EAS-TOP experiment on the surface (81 0 gcm(2) atmospheric depth) and of the LVD experiment in the underground Gr an Sasso Laboratories (3300 m w.e.; E-mu(th) = 1.3 TeV) leading to the meas urement of < N-mu > (E-mu > 1.3 TeV, E-o) in the given energy range. The co mbined operation of the experiments and preliminary results are reported.
