Performance of 2 inch and 3 inch Scintillation Detectors with SiPM Light Readout

Spectroscopic performance of 4 types of large detectors consisting of 3 different scintillators (LaBr

, NaI(Tl) and BGO) coupled to large MPPC array are presented. The measurements are made with S12642-1616PB-50(X) Hamamatsu TSV MPPC array having a 50×50 μm

(16×16 channels). In all measurements the common readout of all channels is used. The results obtained with MPPC, such as energy resolution and linearity, are compared with measurements of the same crystals on classic photomultiplier. Also the possible optimization of data acquisition electronics is presented.
