| Abstract Scope |
Traditional fabrication methods for polymer fast neutron detectors can require weeks of thermal polymerization and labor-intensive processes to achieve sufficient dimensional resolution geometry. This work addresses these limitations by developing additive manufacturing techniques to faster construct detectors with comparable dual-particle performance. In this work, rapid light-curing polymers produced with additive manufacturing techniques have shown feature resolution below the mm scale while maintaining fast curing speeds and light output comparable to industry standard scintillators. The developed automated assembly machine designed around a set of programmable robot arms is shown to be capable of dual alternating layering of light-cured polymer layers and optical segmentation with self-bonded enhanced specular reflector. This allows the production of high-precision two-dimensional arrays in short fabrication times. Results include the design of the additive manufacturing setup, prototype automated assembly, and characterization of the produced geometry. Analysis covers polymer formulation, component emission spectra, process repeatability, and scintillation radiation response. |
