Performance of a scintillator glass shower detector for 20–120 MeV electrons

Abstract A scintillator glass (type : SCG1B) detector of 14 × 14 × 40 cm 3 gives an energy resolution (fwhm) of 6.5%/E −1 2 for low energy electrons, which is better than for lead glass by a factor approximately 0.6. The light yield for SCG1B is 3.4 times that for lead glass (SF5) if the blocks have similar dimensions. Different surface textures are also compared.
