Abstract

Hadronic response and electron identification performance of the new H1 lead-scintillating fibro calorimeter are investigated in the 1 to 7GeV energy range using data taken at the CERN Proton Synchrotron. Theenergy response to minimum ionizing particles and interacting pions are studied and compared to Monte Carlo simulations. The measured energy of pions interacting either in the electromagnetic or in the hadronic section is found to scale linearly with the incident energy, providing an energy resolution sigma/E similar to 38% within a depth of one interaction length and sigma/E similar to 29% for a total depth of two interaction lengths. Several electron identification estimators are studied and combined as a function of energy and impact point. The probability for pions to be misidentified as electrons of any measured energy above 1 GeV ranges from 5% (for 2 GeV incident pions) to 0.49% (at 7 GeV) for an electron detection efficiency of 90%. The probability for pions of a given energy to be misidentified as electrons of the sameenergy falls to 0.25% at 7 GeV.
