Abstract
A prototype electromagnetic calorimeter of 5 x 5 modules has been test ed under a beam of pi0-mesons from events selected by a neutral trigge r under a 40 GeV/c pi- beam. The momentum spectrum and mass resolution for pi0- and eta-mesons were measured. The mass resolution for pi0-me sons with a maximum available energy of 40 GeV is better than 19%. The possibility of identifying pi0- and eta-mesons over a wide range of m omenta and measuring their energy within the geometry of MIS ITEP faci lity is demonstrated.
