V. Agoritsas et al., FAST READOUT OF SCINTILLATING-FIBER ARRAYS USING POSITION-SENSITIVE PHOTOMULTIPLIERS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 357(1), 1995, pp. 78-86
Experimental results obtained with commercially available PSPMs couple
d to 0.5-mm diameter scintillating fiber arrays show space resolution
of < 200 mu m and time resolution better than 1 ns with a detection ef
ficiency of about 90%. In addition, the preliminary studies indicate t
he feasibility of separating double-tracks with a minimum distance of
3 mm using this technology.
