Abstract

This paper gives results from a performance test of a large multicell uranium/scintillator hadron calorimeter used in the AFS experiment at the CERN ISR. Front and back sections of the calorimeter are read-out with separate wavelength shifter bars. Information on the longitudinal and transverse shower development provides separation between electromagnetic and hadronic showers. The results presented concentrate on the angular dependence of linearity, energy resolution, spatial resolution and electron vs hadron separation. The emphasis of the analysis is directed towards the implementation of a pattern recognition program for the calorimeter array.
