Abstract
High resolution imaging gamma-ray detectors were developed using Hamam atsu's 5 '' diameter R3292 position sensitive PMT (PSPMT) [1] and a va riety of crystal scintillator arrays. Special readout techniques were used to maximize the active imaging area while reducing the number of readout channels. Spatial resolutions approaching 1 mm were obtained i n a broad energy range from 20 to 511 keV. Results are also presented of coupling the scintillator arrays to the PMT via imaging light guide s consisting of acrylic optical fibers.
