Abstract
The uranium-scintillator calorimeter of the ZEUS experiment in the HERA electron proton collider at DESY in Hamburg, Germany, is described. It covers 99.8% of the solid angle, has an energy resolution 35%/{radical}E for single hadrons and jets, and 17.5%/{radical}E for electrons. e/h is 1 within 2% in the energy range of 2 to 100 GeV. Test beam results show that an intercalibration at the 1% level is achievable using uranium radioactivity. The calorimeter was commissioned in April, 1992, and has been taking data since May, 1992. Main characteristics of the calorimeter construction, readout, and trigger are reviewed. Experience from the first data taking period, including results on noise, stability of calibration, background from HERA accelerator, and performance of the calorimeter trigger is discussed. (orig.).
