| 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.
