Calibration of the electromagnetic part of the ZEUS calorimeter with electrons
Description
Ten modules of the Uranium-Scintillator-Calorimeter for ZEUS were exposed to the X5-beam at CERN. The momentum of the beam is determined with an accuracy of better than 1.1%. From measurements with electrons in the energy range of 10 to 110 GeV we obtain the following results. The energy resolution is found to be better than 18% / √ E/GeV. A worse resolution measured in the HACO-towers is explained by averaging effects over the beam size. The uranium noise provides an intercalibration of the calorimeter sections within 1.1% for electron signals in the FCAL (1.5% in RCAL). The linearity of the FCAL is better than 0.5%. Nonlinearities of 2% in the RCAL are mainly caused by the photomultipliers. (orig.)
