我们描述了一个实验方案，以评估TOFPET多通道定时电子使用微通道板光电倍增管在单光子计数模式。时间分辨率测量使用：（i）机载电子刺激信号;（ii）Photek PMT 210高速单阳极MCP光电倍增管检测器，以及;（iii）使用像素化多层陶瓷读出的PMT 240 MA多阳极MCP检测器成像。使用ASIC电子器件的电子刺激的实验测量给出43 ps rms的时间分辨率。PMT 210检测器的检测器定时使用40 ps宽的脉冲激光器进行评估，并使用TOFPET电子器件的阈值时间能力进行振幅游走校正。单光子时间分辨优于100 ps rms，并将多阳极像素化MCP探测器与TOFPET系统耦合，实现了256个离散像素的成像。
We describe an experimental programme to evaluate TOFPET multichannel timing electronics using microchannel plate PMTs in single photon counting mode. Time resolution measurements were made using: (i) the on-board electronic stim signal; (ii) a Photek PMT210 high speed single anode MCP photomultiplier detector, and; (iii) imaging with a PMT240MA multi-anode MCP detector using a pixelated multi-layer ceramic readout.Experimental measurements using an electronic stim with the ASIC electronics gave a time resolution of 43 ps rms. Detector timing of the PMT210 detector was evaluated using a 40 ps wide pulsed laser with amplitude walk correction using the time over threshold capability of the TOFPET electronics. Single photon timing resolution of better than 100 ps rms was demonstrated.Furthermore, 256 discrete pixel imaging has been demonstrated by coupling a multi-anode pixelated MCP detector to the TOFPET system.
