In 1994, extensive tests were carried out to evaluate shashlik prototype calorimeter as a candidate for the electromagnetic calorimeter (ECAL) for the Compact Muon Solenoid (CMS) detector. The measured energy resolution is characterized by a stochastic term of 8.5% / ÖE, a noise term of 0.33/  E and a constant term of 0.5 % (E in GeV). Reproducibility of performance of the towers and the uniformity of the calorimeter response have been studied across a large 25 cm × 25 cm area. Effects of radiation damage on the shashlik tower have also been studied.
