The CALOR89 code system has been utilized for extensive calorimeter benchmarking and design calculations. Even though this code system has previously demonstrated its power in the design of calorimeters, major revisions in the form of better collision models and cross-section data bases have expanded its capabilities. The benchmarking has been done with respect to the ZEUS and DO calorimeters. For the most part, good agreement with experimental data has been obtained. The design calculations presented here were done for a variety of absorbers (depleted uranium, lead, and iron) of various thickness, for a given scintillator thickness and for a fixed absorber thickness using various thickness for the scintillator. These studies indicate that a compensating calorimeter can be built using depleted uranium or lead as the absorber, whereas a purely iron calorimeter would be non-compensating. One possibly major problem exists with the depleted uranium calorimeter due to the large number of neutrons produced and due to the large capture cross-section of uranium. These captured neutrons will produce a signal in the scintillator due to secondary gamma rays for many hundreds of nanoseconds and this may contribute substantially to background noise and pile up. 14 figs.
