Results from a beam test of a scintillating fibre hodoscope with multianode photomultiplier read-out — •Carlos Ayerbe Gayoso and Patrick Achenbach — Institut für Kernphysik, Universität Mainz, 55099 Mainz

A scintillating fibre hodoscope has been designed as an electron detector with the future kaon spectrometer at MAMI. A prototype detector has been tested near the focal plane in one of the three existing spectrometers. A timing resolution of less than 1 ns (FWHM) width with detection efficiencies of 99% has been measured with 4 layers of 0.83 mm diameter multiclad fibres. Spatial resolution and the effect of cross-talk between neighbouring channels were studied in detail.

Performance of a prototype with a Cockroft-Walton voltage multiplier as PMT base is also presented.
