Abstract: It is shown that measuring the high energy hadrons in air shower cores at high altitudes (like Yangbajing) can provide some new observables which are sensitive to the cosmic ray composition at the knee region. Assuming a hadron calorimeter (like KASCADE calorimeter) is set up at the center of ARGO array, the event selection conditions are studied for that the primary energies of the selected events range just around the knee. The sample has a reasonable size for 1—2 years’ exposure and a number of observables are shown to be sensitive to the composition.
