A 50 cm diameter, 1.7 cm thick disc of NaI(Tl) scintillator has been mounted to permit edge viewing by four photomultipliers. Energetic heavy ions passing through the scintillator at different positions cause a variation in the division of light among the photomultipliers. We have achieved a performance close to the expected limit for 670 MeV/n· ·neon. Calculations of expected response using an optical model agree well with the measurements.
