COSMIC RAYS AND PARTICLE PHYSICS 477 chambers, with an acceptance of 0. 1 m2 sr, to giant air shower arrays with areas measured in square kilometers. Intermediate in size and energy range are large calorimeters and emulsion chambers.
Collisions at 10-20 Te VThe emulsion chamber technique yields the most detailed information about properties of hadronic interactions in this energy range because it allows detection and energy estimates of single charged hadrons as well as
