Determination of shower central position in laterally segmented lead-fluoride electromagnetic calorimeters

M. Mazouz, L. Ghedira, E. Voutier

The spatial resolution of laterally segmented electromagnetic calorimeters, built of lead fluoride material, is studied on the basis of Monte-Carlo simulations. Parametrization of the relative resolution on the shower position is proposed and optimized in terms of the energy of incoming particles and the elementary size of the calorimeter blocks. A new fit algorithm method is proposed that improves spatial resolution at high energies (> 5 GeV), and provides guidance for the design optimization of electromagnetic calorimeters.
