Abstract A calorimeter, consisting of uranium plates and thin liquid ionization chambers filled with tetramethylpentane (TMP) at room temperature, has been tested using electrons between 10 and 70 GeV. The essential characteristics of the liquid are discussed, including measurements of the free electron lifetime. Results on uniformity, linearity and energy resolution are described and some information on the response to hadrons has been obtained. A single TMP box containing four electrodes and a TMP position detector for electromagnetic showers have also been tested.

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%.
