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 p-n junction surrounding boron as a neutron-conversion material. A gamma-ray detector will be readily incorporated into the same monolithic piece in order to eliminate false-positives. As part of this development effort we will fabricate prototype detectors. The neutron detection efficiency of our best prototypes will be tested in collaboration with Battelle. Our solid-state neutron detectors are expected to have much larger neutron sensitivity and lower power requirements than conventional detectors. These features will enable hand held neutron detectors for customs inspection and other fissile-material detection applications. The low power requirements will also enable wireless neutron detectors for container monitoring applications. In addition, we anticipate that large detector areas can be manufactured at costs below those of conventional neutron detectors for portal screening applications.
