Abstract

We have developed and studied the performance of scintillating glass fiber-optic plates composed of: (1) Terbium activated cladded-glass cores in a matrix of 15 um spacing; and (2) Cerium activated cladded-glass cores in various matrices of 6-25 um spacing. The fluorescence properties of the base glasses and the fiber-optic plates have been studied extensively using Xe lamp and pulser laser spectrometers. The response of the fiber-optic devices to high energy charged particles was measured using 10 GeV/c particles at the SLAC test beam facility and 100 GeV/c particles at Fermi lab. The plates were viewed with a three-stage, gateable image intensifier. Particle tracks and nuclear inter actions were recorded on film. We observe 5 detected flourescence photons per millimeter for minimum ionizing particles for the Terbium glass and 3 detected photons per millimeter for the Cerium glass. The test results indicate that the scintillating glass fiber-optic plates can be used as high resolution tracking detectors for both fixed target and colliding-beam experiments in high energy and nuclear physics.
