TORCH飞行时间探测器的时间分辨率为15 ps，在10 m的飞行路径上可探测到10 GeV/c动量的π/K粒子。切伦科夫光子在10 mm厚的石英板上产生，聚焦到微通道板光电倍增管（MCP-PMT）阵列上，测量光子到达时间和空间位置。半尺寸（660× 1250× 10 mm 3）TORCH演示器模块在CERN的8 GeV/c质子-π介子混合束流中进行了实验。采用了与工业合作伙伴合作开发的有源面积为53× 53 mm 2、粒度为64× 64像素的定制方形MCP-PMT。单光子的定时性能和光子产率已被测量为辐射器中的光束位置的函数，给出与预期一致的测量结果。TORCH在LHCb升级II的高光度运行中的预期性能已经被模拟。
The TORCH time-of-flight detector is designed to provide a 15 ps timing resolution for charged particles, resulting in π/K particle identification up to 10 GeV/c momentum over a 10 m flight path. Cherenkov photons, produced in a quartz plate of 10 mm thickness, are focused onto an array of micro-channel plate photomultipliers (MCP-PMTs) which measure the photon arrival times and spatial positions. A half-scale (660× 1250× 10 mm 3) TORCH demonstrator module has been tested in an 8 GeV/c mixed proton-pion beam at CERN. Customised square MCP-PMTs of active area 53× 53 mm 2 and granularity 64× 64 pixels have been employed, which have been developed in collaboration with an industrial partner. The single-photon timing performance and photon yields have been measured as a function of beam position in the radiator, giving measurements which are consistent with expectations. The expected performance of TORCH for high luminosity running of the LHCb Upgrade II has been simulated.
