EnglishWe have studied the properties of electromagnetic shower counters made of scintillator and lead tiles of different thickness. Light collection is achieved by wavelength shifting fibres sparse in the body of the calorimeter. The counters were tested in a beam of electrons, pions and muons with energies between 2 and 8 GeV. We report here the final results of the test. The energy resolution is in good agreement with what is expected from the sampling fraction, i.e. sigma/E = 0.07/root E, the non uniformity of the response is less than 1% at the centre of a counter and 7 in the boundaries between modules, and the pi/e contamination is at the level of a few 10(-3). Performance of the calorimeter with readout systems able to operate in magnetic field is also reported.
