“日盲”紫外光电倍增管(PMT)对日光不敏感,具有高量子效率、高日盲紫外线获取率、低干扰性、响应速度快、全天候工作等优点而引起人们的重视。文章简要介绍了“日盲”紫外光电倍增管的应用,对日本滨松(Hamamatsu)公司生产的侧窗型日盲紫外光电倍增管R7154的性能作了测试和研究,包括暗计数率、单光电子响应以及渡越时间分散(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,在增益为1.83×10~7时峰谷比可达到3.2,暗计数率低于60Hz,TTS可达到1.22ns,为其实际应用提供了比较可靠的依据。
“Blind ” PMT is insensitive to daylight, attracting people’s attention due to its advantages of high quantum efficiency, high solar UV acquisition rate, low interference, fast response and all-weather working. The article briefly introduces the application of “Blind ” UV photomultiplier tube and tests and studies the performance of side-window day-blind UV photomultiplier tube R7154 manufactured by Hamamatsu Company in Japan, including dark count rate, Single photoelectron response and transit time dispersion (TTS) and so on. The results show that the “Blind” UV photomultiplier tube has a good response to single photoelectrons, with a peak to valley ratio of 3.2 at a gain of 1.83 × 10 -7, a dark count rate of less than 60 Hz and a TTS of 1.22 ns , For its practical application provides a more reliable basis.
