Abstract

The current technology for fast neutron detection imaging is limited in achieving the required high spatial resolution, strong neutron discrimination, and practical time of manufacturing. Traditional fabrication methods require days of thermal polymerization and hundreds of man-hours to produce average resolution pixelated scintillator arrays. The present work helps to eliminate this limitation by developing an additive manufacturing technique to construct such detectors for use in in dual particle imaging applications. In this work, fast-, light-curing resins are used in a prototype automated assembly machine, capable of layering of individual light-cured resin layers and optical segmentation with a self-bonded specular reflector, allowing production of precision one-dimensional scintillator arrays in relatively short fabrication times. Results shown include the design of the scintillator fabrication setup and the characterization of the additively manufactured arrays through analysis of individual resin slabs, adhesion of resin slab to segmentation foils, scintillation resin response to radiation, and the repeatability of the finalized multilayer array procedure.
