Paper Abstract

We report on recent advances in the development of powdered Lu2O3:Eu scintillator screens. The Lu2O3:Eu scintillator has excellent intrinsic material properties including high density (9.5 g/cm3), high average atomic number (63), and a peak emission of 610 nm. We have characterized the performance of screens fabricated from this material in comparison with commercial Gd2O2S:Tb screens. This paper presents resolution in terms of MTF(f), noise properties in terms of NPS(f), and overall NEQ(f), obtained by coupling the screens to a CCD detector. We have included sample radiographic images that demonstrate the ability to produce high quality images. These screens are currently under development, and further improvements in performance are expected with optimization of the scintillator and fabrication methods.
