TORCH（Timing Of Internally Reflected Cherenkov Photons）是一种用于低动量粒子识别的飞行时间探测器。它最初被提议用于LHCb实验升级。TORCH采用模块化设计的石英散热器板。带电粒子通过该辐射器产生的切伦科夫光子的一部分通过全内反射传播，它们在边缘出现，随后聚焦到快速的位置敏感的单光子探测器上。记录的光子的位置和到达时间用于精确地重建它们在石英中的轨迹和传播时间。正在进行的研发计划旨在通过实现一个完整的探测器模块来展示TORCH的基本概念，并已按照以下主要开发路线组织：具有所需粒度和寿命的微通道板光子探测器，专用快速前端电子设备，保留由单光子提供的皮秒定时信息，以及高质量石英辐射器和聚焦光学器件，最大限度地减少光子损失。本文报道了在实验室和带电粒子束试验中成功取得的TORCH结果。它还将介绍最终全尺寸模块原型的最新发展。
TORCH (Timing Of internally Reflected CHerenkov photons) is a time-of-flight detector for particle identification at low momentum. It has been originally proposed for the LHCb experiment upgrade. TORCH is using plates of quartz radiator in a modular design. A fraction of the Cherenkov photons produced by charged particles passing through this radiator propagate by total internal reflection, they emerge at the edges and are subsequently focused onto fast, position-sensitive single-photon detectors. The recorded position and arrival time of the photons are used to precisely reconstruct their trajectory and propagation time in the quartz. The on-going R&D programme aims at demonstrating the TORCH basic concept through the realization of a full detector module and has been organized on the following main development lines: micro-channel plate photon detectors featuring the required granularity and lifetime, dedicated fast front-end electronics preserving the picosecond timing information provided by single photons, and high-quality quartz radiator and focussing optics minimizing photon losses. The present paper reports on the TORCH results successfully achieved in the laboratory and in charged particle beam tests. It will also introduce the latest developments towards a final full-scale module prototype.
