Experimental study of uranium plastic scintillator calorimeters
Abstract
As preparation for the ZEUS high resolution calorimeter, sampling calorimeters made from 3.2 mm plates of depleted uranium read out by plastic scintillator of 3 mm and 5 mm thickness were built. The response of hadrons, electrons, and muons was measured in the energy range between 3 and 100 GeV. In agreement with predictions, the relative response of electrons and hadrons as well as the hadronic energy resolution depend strongly on the thickness of the plastic scintillator. For 3.2 mm depleted uranium and 3 mm thick scintillator equal response for electrons and hadrons is seen over the full energy range. A hadronic energy resolution of 34.5 percent/rt e(GeV) is obtained. Results for the spatial resolution for electrons and hadrons are given. Results from a lead scintillator calorimeter built as a prestudy before uranium plates were available are reported.
