This PFI: AIR Technology Translation project focuses on translating III-V Nitride piezoresistive microcantilever based neutron detector technology to fill the critical technology gap in the neutron detection area arising out of severe worldwide shortage of He-3. The translated technology has the following unique features: (i) vacuum enclosure of the microcantilever sensors, which will result in highly sensitive detection of nuclear radiation, as well as protection of the sensor from environment and unwanted radiation enhancing sensor reliability; (ii) possibility of using arrays of sensors realized through microfabrication techniques, which can offer imaging capabilities and directionality information; (iii) the usage of bimodal detection technique and two functionalization layers to perform highly efficient and unique detection of neutrons. Thus, it provides exemplary performance, cost savings and efficiency when compared to the leading competing neutron detection technology based on Boron-10 in this market space. The project accomplishes this goal by using a relatively inexpensive material with unique material properties and adopting a design strategy involving the design features mentioned above, resulting in a novel neutron detector prototype. The partnership engages Savannah River National Laboratory to provide guidance in the He-detection market space and other aspects including prototype testing and technology commercialization, as they pertain to the potential to translate the technology along a path that may result in a competitive commercial reality. The potential economic impact is expected to be in several tens of millions of dollars in the next eight years, which will contribute to the U.S. competitiveness in this highly critical neutron detection market space. The societal impact, long term, will be in the creation of high-tech workforce and a safer society with vastly mitigated nuclear related threats.

本PFI: AIR技术翻译项目重点翻译III-V型氮化物压阻微悬臂中子探测器技术，以填补世界范围内氦-3严重短缺导致的中子探测领域的关键技术空白。翻译后的技术具有以下独特的特点：(1)微悬臂传感器的真空封装，将导致对核辐射的高灵敏度检测，并保护传感器免受环境和有害辐射的影响，提高传感器的可靠性；（ii）使用通过微加工技术实现的传感器阵列的可能性，可以提供成像能力和方向性信息；（iii）利用双峰探测技术和两个功能化层对中子进行高效和独特的探测。因此，与市场上领先的基于硼-10的中子探测技术相比，它具有卓越的性能、成本节约和效率。该项目通过使用具有独特材料特性的相对便宜的材料，并采用涉及上述设计特征的设计策略，从而实现了这一目标，从而产生了一种新型中子探测器原型。该合作伙伴关系与萨凡纳河国家实验室合作，为氦探测市场空间和其他方面提供指导，包括原型测试和技术商业化，因为它们涉及将技术转化为可能导致竞争性商业现实的路径的潜力。预计未来8年的潜在经济影响将达到数千万美元，这将有助于美国在这个高度关键的中子探测市场领域的竞争力。从长远来看，其社会影响将是创造高科技劳动力和一个更安全的社会，大大减轻了与核有关的威胁。
