We find that the pair meter technique for measuring high energy prompt muons can be very efficient in such an endeavor. As a by product, it allows to cleanly probe the change in composition of the primary cosmic rays expected at high energies.5 pages, 2 figuresHigh Energy Physics - PhenomenologyAstrophysicsHigh Energy Physics - Experimenttext
