Abstract: [Background] With the development of semiconductor photon detector technology, a novel signal readout device named multi pixel photon counter (MPPC) has gradually been developed and applied in radiation detection.[Purpose] This study aims to verify the performance of the MPPC and compare it with photomultiplier tube (PMT) in linearity and energy resolution.[Methods] First of all, scintillation detectors with MPPC coupling with scintillation crystals such as thallium-doped sodium iodide (NaI(Tl)), CsI, and Bi4Ge3O12(BGO) crystals was constructed to test three characteristic γ-ray energy peaks of 137Cs and 60Co. Then the same tests were done with PMT (Hamamatsu H7195) coupling with these crystals as the parallel experiments. Simultaneously, the output signal of the MPPC was collected by using a waveform digitizer (CAEN DT5730) and a self-made pre-amplifier.[Results] The results show that the MPPC has a slightly worse energy resolution compared to that of PMT, but reserves a similar energy linearity.[Conclusion] This MPPC could be applied in circumstances such as the space detection and medical applications instead of PMT.
