Developments in Gd2O2S based pixelated-metallic aperture arrays

Radiographic imaging represents a vital capability within non-destructive assessment, quality control and fundamental science. This study focuses on Gd2O2S:Tb3+ based scintillating composites incorporated into pixelated-metallic aperture screens, attached to amorphous silicon-based flat panels. Performance metrics are explored through coupled MCNP6- FRED simulations; here, scintillation light transport is investigated as a function of pixelated screen geometry and optical characteristics. For the first time, we demonstrate image acquisition with a 100 micron thick pixelated metallic aperture screen. The results demonstrate promising improvements to x-ray interaction rates while maintaining image quality.
