Abstract: (Elsevier)

A study has been made of the characteristics of electromagnetic calorimeter modules with the structure (1.4 mm Pb + 4 mm Sc)×60 layers using 72 wavelength shifting fibers for readout. These modules were made according to a specially developed technology and were tested with a beam of electrons, pions and muons with energies between 0.5 and 5 GeV. It was found that their energy resolution is σE/E = 0.014+0.067/ E[ GeV ] , response nonuniformity <2%, and π /e rejection at the level 10 −2 to 10 −3 .
