| As one of silicon photomultiplier (SiPM), multi-pixel photon counter (MPPC) would be attracted due to its advantages of insensitive to magnetic field, high gain, high photon detection efficiency and fast response, and it was applied in high-energy physics experiment. Meanwhile, the solar-blind ultraviolet (UV) photomultiplier tube (PMT) is used in a variety of occasions for its advantages in ultraviolet detection. In this paper, performance of these two optoelectronic devices have been studied, it includes:Firstly, we study the performance of MPPC module. In lab, we designed and built the test system for MPPC, and then tested the performance of MPPC, including stability test, gain consistency and absolute gain test. Results show that MPPC has a well long term stability and gain consistency, and absolute gain of MPPC could be 2.3 × 106.Secondly, position sensitive detector based on SiPM has been studied. Four MPPC modules were spliced into a position sensitive detector with an area of 4x16 cm2. Position resolution of the detector has been measured. Results show that one-dimensional position resolution of MPPC is 0.9695mm, and then the detector was used to be an imaging detector.Thirdly, the performance of solar-blind ultraviolet photomultiplier tube was tested, including single photoelectron spectrum, gain of detector, and transit time spread (TTS), etc. Results show that the solar blind ultraviolet photomultiplier tube have a good response to single photoelectron, and the anode dark count rate of PMT is 60Hz when trigger threshold is 3mV. Meanwhile, when gain of PMT is 1.83 × 107, ratio of peak to valley could be 3.21 and TTS is just 1.22 ns.Through the performance study of MPPC and solar blind UV photomultiplier tube, we have a better understanding of these two optoelectronic devices, and it also provide many references for high energy physics experiments in advanced research on these two optoelectronic devices in the future. |
