An efficient method and system for simultaneously measuring the performance of vast scintillating materials

A method and system for automatically and simultaneously measuring the light output of multiple scintillators,or each scintillating unit of an array,were developed.Using a large area flat panel PSPMT H8500,the light output and energy resolution were obtained automatically by comparing with reference scintillators or array using an Energy Table,Look-up Table and energy spectrum data.The aim of developing an efficient performance evaluation of scintillators was achieved.Using the method,a scintillator performance testing system was set up and six LYSO crystals and a 3×3 LYSO array were measured.The results showed that the light output and energy resolution were accurately measured automatically.The deviation of repeat measurements for the same sample was not more than 2%,and the nonlinear deviation of the system was not more than 3%.The system is suitable for measuring the performance of crystals,especially where the mass measurement of crystals and arrays is required.
