TORCH - a Cherenkov based Time-of-Flight PID Detector for the LHCb Upgrade at CERN — •Klaus Föhl for the TORCH collaboration — now at II. Physikalisches Institut, Heinrich-Buff-Ring 16, Justus Liebig University Giessen, D-35392 Gießen
TORCH is proposed for the LHCb experiment at CERN to provide positive particle identification for low momentum (2 to 10 GeV/c) kaons, and is currently in the Research-and-Development phase. In general TORCH is a large-area (6×5 m2) precision time-of-flight DIRC-type detector wall, where a fraction of the produced Cherenkov light is propagating by total internal reflection inside a 10 mm thick amorphous fused silica radiator plate, and entering at the edges into readout optics that focusses them onto fast, position-sensitive single-photon detectors. An overview of the required large-scale focussing optics, the micro-channel plate photon sensor development, and the custom-made electronics will be given. Recent results achieved in the laboratory and in charged particle beam tests will be reported, and the latest developments towards a final full-scale module prototype will be introduced.
