Abstract We have developed a method for reading out scintillator plates in a compact calorimeter using embedded wavelength-shifting fibres coupled to photomultipliers. A test calorimeter using this technique, with uranium plates as the passive medium, was placed in test beams of 1 to 80 GeV. Results on resolution, uniformity, and electron-pion discrimination are presented, as well as a discussion of compensation (the near-equality of electron and hadron responses).

Abstract We describe the construction, calibration and performance of the central electromagnetic calorimeter of the UA1 experiment at the CERN proton-antiproton collider. The calorimeter is of the lead-scintillator sandwich type. It is 26.4 radiation lengths thick and covers a surface of about 50 m 2 . We estimate the resolution of the calorimeter for electrons of energy greater than 1 GeV to be the sum in quadrature of 15% √E ( E in GeV) and a constant 3%. The first term comes from the inherent resolution of the calorimeter due to sampling fluctuations and photostatistics. The second term comes from uncertainties in the calibration procedure and dominates the resolution for electrons from W and Z 0 decay. The uncertainty in the overall energy scale also reflects the uncertainties in the calibration procedure and is estimated to be 3%.
