We have studied the performance of a scintillating glass fiber-optic plate with minimum ionizing particles. The target is composed of terbium activated cladded-glass cores in a matrix of 25 Â¿m spacing. The plate was viewed by a three-stage, electrostatically focussed image intensifier. Particle tracks were observed with a width consistent with the resolution of the device. Details of the detection system and future developments are discussed.
