We report the results of measurements performed using a tracking detector based on 835 mu m scintillating fibres read out by two position-sensitive photomultipliers. A six-layer hodoscope consisting of 1.2 m long fibres has been built and tested using cosmic rays. Subsequently, two such hodoscopes have been assembled and tested using a hadron beam at the CERN PS. The efficiency per plane is found to be about 70% and the point resolution about 130 mu m. The signal-to-noise ratio is about 2.4 and is dominated by crosstalk in the position-sensitive photomultipliers.

Abstract
We report the results of measurements performed using a tracking detector based on 835 mu m scintillating fibres read out by two position-sensitive photomultipliers. A six-layer hodoscope consisting of 1.2 m long fibres has been built and tested using cosmic rays. Subsequently, two such hodoscopes have been assembled and tested using a hadron beam at the CERN PS. The efficiency per plane is found to be about 70% and the point resolution about 130 mu m. The signal-to-noise ratio is about 2.4 and is dominated by crosstalk in the position-sensitive photomultipliers.File in questo prodotto:
