SCINTILLATING-FIBER DETECTORS USING POSITION-SENSITIVE PHOTOMULTIPLIERS

Scintillating fibre technology has made substantial progress, and has demonstrated great potential for fast tracking and triggering at high luminosity experiments in Particle Physics. This talk presents some re cent issues of the RD-17 project at CERN for fast and precise readout of scintillating fibre arrays, as well as for upgrade of position-sens itive photomultipliers. Excellent matching of scintillating fibre and position-sensitive photomultiplier, in particular in time characterist ics, allowed to realise high detector performances, typically represen ted by spatial resolution of similar to 125 mu m as well as time resol ution better than 1 ns with detection efficiency greater than 95 %.
