    Abstract

    We describe the results of beam tests of three uranium-liquid argon calorimeter modules constructed for the DØ detector at the Fermilab Tevatron collider. As part of the calibration procedure, these modules were exposed to beams of electrons, pions and muons between 10 and 150 GeV/c before their installation in the end calorimeter of the completed DØ detector. We obtain an electromagnetic sampling resolution of 15.7%/√E and constant term of 0.3%. The hadronic sampling resolution is 45%/√E (degraded to 50%/√E by the effects of upstream material) and the constant term is 4%. The calorimeter is linear to 0.5%, and the electromagnetic to hadronic response ratio is between 1.02 and 1.09 over this range of momenta. For an electron efficiency of 95% we obtain a rejection factor against pions of ∼ 900-3000 for particles in the momentum range between 50 and 150 GeV/c. We also compare our results with the predictions of a detailed Monte Carlo simulation.
