“…The reason is that we use multi-channel PMT H7546B followed by multichannel circuit to read out the light signal instead of XP2262B with single channel circuit, for multi-channel gain and noise are always bigger than that of single channel, both for circuit and PMT. The same phenomena occur when light signal was read out with other multi-channel photodetector [24][25][26][27][28].…”

Cerium doped lutetium oxyorthosilicate scintillators, such as LYSO, which possess high stopping power, high light output and fast decay time, are promising candidates for use in positron emission tomography. In this paper, the luminescence and nuclear spectroscopic properties of two LYSO samples, used in the NN-PET detectors, are studied. UV-excited emission spectra show that maximum emission spectral values are within the range of 400-425nm, which is well compatible with spectral response of PMT H7546B. The decay time, energy resolution, light output and energy spectra related to coincidence time window were investigated. The decay times of the two LYSO samples are 34.16±1.43ns, 34.26±1.95ns, respectively. The energy resolution and the light output, relative to NaI(Tl), are 10.25%±0.06%, 10.17%±0.10% and 75.3±5.7, 76.1±5.8 respectively when detected with PMT XP2262B. The energy spectra change obviously with coincidence time window and coincidence energy resolution is 14% when obtained using coincidence detector based on LYSO and H7546B.

“…This paper will model the distribution of the gamma-ray's arrival time for various SPAD jitters and light detection efficiencies. Standard SPAD jitters range from roughly 100 ps FWHM in fully digital SPAD TDC arrays to several hundred picoseconds in silicon photo-multipliers, though jitters as small as 70 ps sigma have been measured in SiPMs [9]- [12]. Light detection efficiencies range from over 25% for optimized silicon photo-multipliers with high fill factors and PDPs to under 5% in some modern SPAD TDC arrays with low fill factors [11], [13] .…”

Abstract-We present a statistical analysis of the tradeoffs between detector jitter and light detection efficiency for TOF PET gamma-ray detectors based on SPAD arrays and crystal scintillators. Results show that increasing the light detection probability is more important to improving the coincidence timing resolution than decreasing the detector jitter for modern scintillators. For a SPAD TDC array with a fill factor around 15% and a detector jitter of 120 ps, it is shown that a SiPM with a 30% fill factor and a jitter of 240 ps will produce a better timing resolution when using a LYSO crystal. Results also imply that SPAD TDC arrays might be competitive in TOF PET with SiPMs if faster scintillators are developed in the future and SPAD TDC arrays maintain a much lower jitter than SiPMs.
