火炬飞行时间探测器的设计目的是在大范围的动量范围2−10GeV/c内提供粒子识别。该探测器利用带电粒子穿过10毫米厚石英板产生的瞬间切伦科夫光。光子通过全内反射传播，并聚焦到由位置敏感微通道板光倍增管(MCP-PMT)探测器组成的探测器平面上。其目标是实现70ps的单光子计时分辨率，通过结合来自大约30个检测到的光子的信息，提供每个带电粒子15ps的计时精度。MCP-PMT探测器是与商业合作伙伴(Photek Ltd，UK)共同开发的，提供了一个相当于8×128像素当量粒度的方管，有效面积为53×53 mm 2。一个大型火炬演示器，尺寸为660×1250×10 mm 3的石英板，由一对带有定制读出电子设备的MCP-PMT读出，已在CERN PS的测试束活动中得到验证。初步结果表明，所要求的性能接近达到要求。给出了LHCB实验中全尺寸火炬探测器的预期性能。
The TORCH time-of-flight detector is designed to provide particle identification in the momentum range 2− 10 GeV∕ c over large areas. The detector exploits prompt Cherenkov light produced by charged particles traversing a 10 mm thick quartz plate. The photons propagate via total internal reflection and are focused onto a detector plane comprising position-sensitive Micro-Channel Plate Photo-Multiplier Tubes (MCP-PMT) detectors. The goal is to achieve a single-photon timing resolution of 70 ps, giving a timing precision of 15 ps per charged particle by combining the information from around 30 detected photons. The MCP-PMT detectors have been developed with a commercial partner (Photek Ltd, UK), leading to the delivery of a square tube of active area 53× 53 mm 2 with a granularity of 8× 128 pixels equivalent. A large-scale demonstrator of TORCH, having a quartz plate of dimensions 660× 1250× 10 mm 3 and read out by a pair of MCP-PMTs with custom readout electronics, has been verified in a test beam campaign at the CERN PS. Preliminary results indicate that the required performance is close to being achieved. The anticipated performance of a full-scale TORCH detector at the LHCb experiment is presented.
