Scintillating fibre 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 recent issues of the RD-17 project at CERN for fast and precise readout of scintillating fibre arrays, as well as for upgrade of position-sensitive photomultipliers. Excellent matching of scintillating fibre and position-sensitive photomultiplier, in particular in time characteristics, allowed to realise high detector performances, typically represented by spatial resolution of ∼ 125 μm as well as time resolution better than 1 ns with detection efficiency greater than 95 %.
