TORCH is a large-area, high-precision time-of-flight (ToF) detector designedto provide charged-particle identification in the 2-20 GeV$/c$ momentum range.Prompt Cherenkov photons emitted by charged hadrons as they traverse a 10mmquartz radiator are propagated to the periphery of the detector, where they arefocused onto an array of micro-channel plate photomultiplier tubes (MCP-PMTs).The position and arrival times of the photons are used to infer the particles'time of entry in the radiator, to identify hadrons based on their ToF. TheMCP-PMTs were developed with an industrial partner to satisfy the stringentrequirements of the TORCH detector. The requirements include a finely segmentedanode, excellent time resolution, and a long lifetime. Over an approximately10m flight distance, the difference in ToF between a kaon and a pion with10GeV$/c$ momentum is 35ps, leading to a 10-15ps per track timing resolutionrequirement. On average 30 photons per hadron are detected, which translates toa single-photon time resolution of 70ps. The TORCH research and developmentprogram aims to demonstrate the validity of the detector concept throughlaboratory and beam tests, results from which are presented. A timingresolution of 70-100ps was reached in beam tests, approaching the TORCH designgoal. Laboratory timing tests consist of operating the MCP-PMTs coupled to theTORCH readout electronics. A time resolution of about 50ps was measured,meeting the TORCH target timing resolution.
