An experiment to operate an air shower array, a burst detector (or a hadron calorimeter) and an emulsion chamber is under way at Mt. Chacaltaya (5,200 m, Bolivia), in order to study the hadron interactions and the primary cosmic rays in the energy region exceeding 1015 eV. The number of hadrons in the air shower, detected by the burst detector, indicates that the proton fraction among the primary cosmic rays exceeds 50%.
