TORCH探测器提供低动量粒子识别,结合飞行时间(TOF)和切伦科夫技术,在10米的飞行距离内实现2-20 GeV/c之间的带电粒子pi/K/p分离。测量需要70 ps的单切伦科夫光子的时间分辨率。为了实现精确的光子检测,我们开发了具有高精度TOF测量电子器件的定制微通道板光电倍增管(MCP-PMT)。该电子设备可从MCP-PMT测量超过阈值的时间,并具有10千兆以太网读数功能。本文报道了一个5120通道的系统,目前仪器的MCP-光电倍增管对的设计和性能,但有能力读出十个定制的MCP-光电倍增管设备在未来。
The TORCH detector provides low-momentum particle identification, combining Time of Flight (TOF) and Cherenkov techniques to achieve charged particle pi/K/p separation between 2–20 GeV/c over a flight distance of 10 m. The measurement requires a timing resolution of 70 ps for single Cherenkov photons. For precision photon detection, customised Micro-Channel Plate Photomultiplier Tubes (MCP-PMTs) with high precision TOF measurement electronics have been developed. The electronics measures time-over-threshold from the MCP-PMT and features a 10-Gigabit Ethernet readout. This paper reports the design and performance of a 5120-channel system which currently instruments a pair of MCP-PMTs, but has the capacity to read out ten customised MCP-PMT devices in the future.
