Abstract

A prototype of a vertex detector with polystyrene scintillating fibres and cells with liquid scintillator using CCD readout has been studied. For the polystyrene fibres of 150 μm diameter the number of clusters per unit track length is n0 = 3.17 mm−1 with a straight-line rms residual σp ⋍ 70 μm and a track impact parameter precision δp ⋍ 35 μm. For the detector with the cells with liquid scintillator n0 is obtained to be 3.10 mm−1 and σliq ⋍ 68 μm, δliq ⋍ 33 μm. The two-track resolution is 110 μm.
