Experimental determination of the intrinsic fluctuations from binding energy losses in [formula omitted] hadron calorimeters

Abstract

Fluctuations due to binding energy losses were determined experimentally for a sampling hadron calorimeter with an active medium consisting of layers of silicon mosaics. The absorbers were uranium layers ( Si U ). The calorimeter was exposed to hadrons (protons) at incoming energies of 8, 10, and 12 GeV. The contribution ( σ bind) of the binding energy losses fluctuations to the energy resolution of this compensating hadron calorimeter was found to be σ bind ≈ 47.8%.
