Abstract
Fluctuations due to binding energy losses were determined experimentally for sampling hadron calorimeters with layers of silicon mosaics as active medium and with either Fe layers (Si/Fe) or combinations of Pb and Fe layers (Si/Fe + Pb) as absorbers. The calorimeters were exposed to hadrons (π) at incoming energies of 10, 15, 20, 30, 40, 50 and 70 GeV at the CERN-SPS. The contributions (σbind) of the binding energy losses fluctuations to the energy resolution of these hadron calorimeters were found to be σbind = (19.8±2.4)% and (49.9±14.1)% for Fe and Pb, respectively. σbind = (25.9±2.1)% has been found for a compensating Si/Fe + Pb calorimeter. These results are found in good agreement with previous measurements made at lower energies. As expected, an overall nonlinearity of about 3.5%, in the 10–70 GeV energy range, has been observed in the Si/Fe noncompensating (e/π∼ 1.11 at 10 GeV) calorimeter energy response.
