POSITION-SENSITIVE DELTA-E DETECTOR

A method is described for simultaneously measuring the interaction position and energy loss in a thin scintillator for energetic charged particles. Wave shifting optical fibers embedded in a scintillator combined with a Hamamatsu R2486 crossed wire anode, position sensitive photomultiplier tube are used, A prototype detector gave 2.4 mm FWHM position resolution for minimum ionizing cosmic rays. Studies to extract a single pulse linear in position from the phototube pulses using neural networks are described.
