摘要
The performances of the Hl liquid argon calorimeter modules for the energy measurements and identification of electons are studied with test data taken at CERN in the energy range 5 to 166 GeV. Various electron identification estimators exploiting global or detailed shower characteristics are studied and compared. The usage of impact position measurements is also discussed. A best combination of robust shower estimators leads typically to pi-misidentification probabilities in the range 1.5 to 5.0 x 10(-3) at 30 GeV for 95% electron detection efficiency. This further reduces to approximately 10(-4) for these pions to be misidentified as electrons below 25 GeV.
