论文摘要
This paper reports on the time resolution of two photodetectors operated as single photon counters at high rate: a Hamamatsu R13742-103-M64 "conventional" (based on metal dynodes) multi-anode photomultiplier tube (MaPMT) and a Hamamatsu R10754-07-M16 microchannel plate photomultiplier tube (MCP-PMT). MCP-PMT在低光子速率下显示了〜70 ps fWHM(〜30 ps rms)的时间分辨率(运输时间扩散或抖动),但饱和量高于〜100 kHz/mm^2。 MAPMT可以将光子计数速率处理至最高测试的10 MHz/mm^2。当仅照亮像素中心时,其时间分辨率为〜250 ps fwhm(〜110 ps rms),但是当整个像素面积照亮时,像素边缘效应将分辨率降低到〜400 ps fwhm(〜170 ps rms)。
This paper reports on the time resolution of two photodetectors operated as single photon counters at high rate: a Hamamatsu R13742-103-M64 "conventional" (based on metal dynodes) multi-anode photomultiplier tube (MaPMT) and a Hamamatsu R10754-07-M16 microchannel plate photomultiplier tube (MCP-PMT). The MCP-PMT shows a time resolution (transit time spread, or jitter) of ~70 ps FWHM (~30 ps RMS) at low photon rates, but saturates above ~100 kHz/mm^2. The MaPMT can handle photon counting rates up to the highest tested, 10 MHz/mm^2. Its time resolution is ~250 ps FWHM (~110 ps RMS) when only the pixel center is illuminated, but pixel edge effects degrade the resolution to ~400 ps FWHM (~170 ps RMS) when the entire pixel area is illuminated.
