An Energy Resolution Test on a SCG1-C Scintillator Glass at Intermediate Energies

We performed a test of a SCG1-C scintillator glass (Ohara Optical Glass Manufactoring Co., Ltd) at the CERN SC with electrons at ener ties from 100 to 300 Mev. The block surface was 15×15 cm2 and its length was 43.5 cm. corresponding to 10 radiation lengths. The energy resolution of the SCG1-C block was measured at five momentum values and the results can be fitted by the following form: ?/E = (0.80/?V)% with E expressed in Mev.
