The AFS hadron calorimeter has been designed to permit unbiased selection and study of events characterized by large transverse energy. Half of the calorimeter is now installed at the Intersecting Storage Rings at CERN; in its final form it will cover the full azimuth over a polar region of 40/sup 0/ < theta < 140/sup 0/. The calorimeter is built in a modular way from 128 uranium stacks (plus 64 copper catchers), each of which is a fine sampling uranium/copper scintillator sandwich. Uranium is used as passive absorber material to achieve optimum resolution and unbiased triggering. Fluctuations in the energy deposited by hadrons are compensated on an event-by-event basis by the energy gained from fission induced in the development of the hadronic shower. This compensation provides excellent hadron energy resolution, as well as nearly equal energy response for hadronic and electromagnetic showers. This paper reports on the calibration of the calorimeter modules and presents preliminary results from studies in a test beam.
