TORCH探测器正在开发用于低动量粒子识别，结合飞行时间和切伦科夫技术，在10米的飞行距离上实现高达10 GeV/c的带电粒子pi/K/p分离。这要求单个光子的时间分辨率达到70ps。基于现有的可扩展设计，火炬读出系统的生产和测试已经在过去的一年里进行了，并且一种具有128通道的新型定制微通道板（MCP）光电倍增管器件已经被仪器化。本文将介绍用于测试光束飞行时间测量的读出系统的研制及其性能。我们还将讨论TORCH系统与TimePix3望远镜之间的通信和数据对齐，以便提供航迹重建。
The TORCH detector is being developed for low-momentum particle identification, combining time-of-flight and Cherenkov techniques to achieve charged particle pi/K/p separation up to 10 GeV/c over a flight distance of 10m. This requires a timing resolution of 70 ps for single photons. Based on an existing scalable design, production and testing of a TORCH readout system has been undertaken over the past year, and a novel customized Micro Channel Plate (MCP) photomultiplier device with 128-channels has been instrumented. This paper will report on the development of the readout system which is being used to measure time-of-flight in a test-beam, and its performance. We will also discuss the communication and data alignment between the TORCH system and the TimePix3 telescope in order to provide track reconstruction.
