在中国的超级Tau-Charm设施（STCF）中，类似于dirc的飞行时间探测器（DTOF）是一种切伦科夫光探测器，它使用TOF技术来识别带电粒子。为了实现在2-Ge/c动量下提供$3\sigma \pi $ /K分离的预期目标，需要优于50 ps的单光子时间分辨率，而电子器件的贡献应低于15 ps。为了满足高通道数集成度的要求，dof探测器采用了采用前沿鉴别和基于现场可编程门阵列（FPGA）的时间-数字转换器（tdc）的定时电子器件。本文报道了一期工程的成果，其中构建了128通道的定时电子器件，并对其性能进行了评估。考虑系统时钟分布和同步的不确定性，电子器件的固有时序分辨率优于10ps有效值。采用快速微通道板光电倍增管（MCP-PMTs）作为切伦科夫光电探测器，采用时间超阈值（TOT）测量进行时间行走校正，测得的单光子时间分辨率优于40-ps rms。测试结果表明，所设计的定时电子器件具有高精度和高集成度的优点，这是未来皮秒定时探测器所需要的。
The DIRC-like time-of-flight detector (DTOF) at the Super Tau-Charm Facility (STCF) in China is a Cherenkov light detector that uses the TOF technique to identify charged particles. To achieve the expected target that provides a $3\sigma \pi $ /K separation at 2-Ge/c momentum, a single-photon time resolution of better than 50 ps is required, while the contribution from electronics should be lower than 15 ps. To meet the requirements with high channel count integration, the timing electronics using leading-edge discrimination and field-programmable gate array (FPGA)-based time-to-digital converters (TDCs) are employed in the DTOF detector. This article reports the results of the first phase of project where the timing electronics with 128 channels has been constructed and its performance has been evaluated. Including the uncertainty of system clock distribution and synchronization, the intrinsic timing resolution of the electronics is better than 10-ps rms. Taking fast microchannel plate photomultiplier tubes (MCP-PMTs) as Cherenkov photodetectors and adopting time-over-threshold (TOT) measurement for time walk correction, the measured single-photon time resolutions are better than 40-ps rms. The test results confirm that the proposed timing electronics has advantages of high precision and high integration, which is highly demanded in future picosecond timing detectors.
