Abstract :
A calorimeter made by a homogeneous electromagnetic section consisting of 100 BGO crystals and by a sampling hadronic section made of copper and optical fibers was tested with pion and electron beams. The presence of UV filters and the waveform analysis in the crystal section and the use of scintillating and undoped fibers in the hadronic part make possible to apply the dual readout method to the whole detector. The estimation of the electromagnetic fraction of hadronic showers developing in the whole system allows to correct the energy measurements for its electromagnetic fraction fluctuations upgrading the energy resolution. The performance obtained by the BGO section are reported in this paper.
