Abstract :
The electromagnetic section of a full hadronic calorimeter, using uranium absorbers and 0.25 m/sup 2/ of silicon active area, was investigated. Mosaic modules, consisting of 18 trapezoidal silicon detectors, 400- mu m thick, were used in the construction of sampling calorimeters. The overall performance of the detectors and associated electronics was found to be stable and reliable. During a four-week run no energy calibration variation occurred. A reduction of the energy sensed in electromagnetic showers, caused by the fiberglass (G10) supports of the silicon mosaic, was observed. This effect can be exploited to equalize the response of a Si/U hadronic calorimeter to incoming electrons and hadrons.<>
