Abstract

We present results from the barrel depleted uranium/TMP calorimeter modules constructed by the UAl Collaboration. Electromagnetic and hadronic energy resolutions have been measured using electron and pion beams with momenta in the range 7 to 70 GeV/c. Results on the energy linearity and the spatial uniformity of response are reported . The electromagnetic shower position resolution has been measured as a function of energy using a fine grained position detector placed at a depth of - 3.5Xo. The noise arising both from the electronics chain and from the uranium radioactivity is compared with 70 GeV/c muon signals. The ratio of the electron to pion response has been measured both as a function of the energy and of the electric field. The high lateral and longitudinal granularity of the calorimeter and the presence of a position detector have been used to determine the electron-pion separation as a function of energy .
