“…By fitting with a Gaussian function (solid curve), the timing resolution for a single photon is estimated to be 80 ps including the timing jitter of the measurement system (26 ps) and light pulse (29 ps). The resolutions at lower gain are also measured to be 97 ps (4.7×10 4 ) and 104 ps (4.2×10 4 ), confirming the dependence of the timing resolution upon the gain of the HPD, as discussed in [14]. The resolution is compatible with that of the transit time spread (TTS) of commercially available fast PMTs.…”

A multi-pixel photon sensor with single-photon sensitivity has been developed. Based on a hybrid photo-detector (HPD) technology, it consists of a photocathode and a multi-pixel avalanche diode (MP-AD). The developed HPD has a proximity-focused structure, where the photocathode and MP-AD face each other with a small gap of 2.5 mm. The MP-AD, which has an effective area of 16mm×16mm, is composed of 8×8 pixel and has been specially designed for the HPD. The maximum gain of the HPD is 5×10 4 , sufficiently high to detect single photons with a timing resolution better than 100 ps. Up to four photoelectrons can be clearly identified as distinct peaks in a pulse-height spectrum, thanks to the low noise characteristics of the HPD. It is also 1 demonstrated that the HPD can be operated with good performance in a magnetic field as high as 1.5T.
