摘　　要：Silicon photomultipliers （SiPMs） have remarkable advantages for use in photo-detection. Compared with PMT, SiPM shows advantages of high gain, excellent time resolution, insensitivity to magnetic fields and a lower operating voltage. SiPMs from Hamamatsu are used in the electromagnetic calorimeter （ECAL） sub-detector in the Positron Electron Balloon Spectrometer （PEBS） experiment, a balloon-borne spectrometer experiment aiming at the precise measurement of the cosmic-ray positron fraction. This paper introduces the evaluation and test results of several SiPM detector types, the dedicated front-end application specific integrated circuit （ASIC） electronics and the design of the data acquisition system （DAQ） system.Silicon photomultipliers （SiPMs） have remarkable advantages for use in photo-detection.
