【摘要】：多像素光子计数器(MPPC)作为一种硅光电倍增管(SiPM),因具有对磁场不灵敏、高增益、高光子探测效率以及响应速度快等优点而受到人们关注,并被应用于高能物理实验。而日盲紫外光电倍增管(PMT)因其对紫外波段探测的优势也被应用于多种场合。本文主要针对这两种光电器件作了性能研究,主要内容包括：第一,对MPPC模块的性能研究。针对MPPC进行了测试系统的设计与搭建,测试了MPPC的性能,包括MPPC的稳定性测试、增益一致性调节以及MPPC的绝对增益测试。结果表明MPPC具有较好的长时间稳定性以及增益一致性,其绝对增益达到2.3×106。第二,基于SiPM位置灵敏探测器的研究。使用四块MPPC拼接成一个4×16的位置灵敏探测器,对探测器进行了一维位置分辨的测试,结果表明MPPC的一维位置分辨为0.9695mm。同时也研究了该探测器的成像情况。第三,针对日盲紫外光电倍增管的性能作了测试,包括单光电子谱,增益以及渡越时间分散(TTS)等。结果表明,“日盲”紫外光电倍增管对单光电子具有较好的响应,触发阈值为3mV时阳极暗计数率为60Hz,在增益为1.83×107时峰谷比可达到3.2,TTS可达到1.22ns。通过对MPPC以及日盲紫外光电倍增管的研究,了解了这两种光电器件的性能,也为在高能物理领域进一步研究这两种光电器件提供了参考。
[Abstract]:Multi pixel photon counter (MPPC) as a silicon photomultiplier tube (SiPM), because it has not sensitive to magnetic fields, high gain, high photon detection efficiency and response speed and attention, and is applied in high energy physics experiments. And the ultraviolet solar blind photomultiplier tube (PMT) because of its the band of ultraviolet detection advantage has also been applied to a variety of occasions. This paper focuses on two kinds of optoelectronic devices have been studied, the main contents include: first, the research on the performance of MPPC module for MPPC. The design and construction of the test system, the MPPC performance test, including the stability test of the MPPC gain consistency adjustment and absolute gain of MPPC. Test results show that MPPC has good stability and long time gain consistency, the absolute gain of up to 2.3 x 106. second, SiPM position sensitive detector based on the use of four MPPC spell. Connected to a 4 x 16 position sensitive detector, the detector is a one-dimensional position resolution test results show that the one-dimensional position of MPPC resolution 0.9695mm. also examined the imaging detector. Third, for the solar blind UV photomultiplier tube performance testing, including single photoelectron spectrum, gain and the transit time dispersion (TTS). The results show that the solar blind ultraviolet photomultiplier tube has a good response to the single optical electronics, triggering threshold of 3mV anode dark count rate is 60Hz, the gain is 1.83 * 107 peak valley ratio can reach 3.2 TTS can reach 1.22ns. by the photomultiplier tube research on the MPPC and the solar blind ultraviolet photoelectric, understanding the properties of these two kinds of photoelectric devices, but also provides a reference for further study of these two kinds of optoelectronic devices in the field of high energy physics.
