Abstract :
The results of a beam test are presented concerning the energy resolution of a calorimeter hodoscope prototype of PWO (PbWO4) crystals, measured by electron beams having energies between 0.5 and 2.5 GeV. The hodoscope consists of a 3 × 3 matrix of modules of PWOs having dimensions of 20 mm × 20 mm in cross section and 200 mm in length. The energy dependence of the energy resolution is obtained to be (σ/EGeV))2=((0.0310±0.0011)/E(Gev))2+(0.0079±0.0025)2, fitted by a quadratic form.
