Nanorod Array Solid State Neutron Detectors

In this Phase I SBIR project, Synkera proposes to develop and commercialize solid-state neutron detectors of a unique architecture that will enable sensor modules for a variety of operating environment. The neutron detectors are based around nanoporous anodic aluminum oxide, and will be fabricated using a combination of gas-phase and solution-based deposition methods. The detectors will incorporate a schottky junction surrounding a neutron-conversion material. As part of this development effort we will develop the deposition methods required for the various components of the detector and use modeling to evaluate the feasibility of the design. Our solid-state neutron detectors are expected to have much larger neutron sensitivity toward fast neutrons than conventional detectors at a lower weight and much lower power requirements. These features will enable solid state neutron spectrometers meeting all the NASA requirements on weight, volume, and power. We anticipate that large detector areas can be manufactured at costs below those of conventional neutron detectors.
