Low-dose inspection for nuclear threats using monochromatic gamma-rays is a novel method to detect shielded nuclear material (SNM) with a potential to significantly outperform currently employed methods. The key advantage of the method we are pursuing is in low dose (20 mrad), ability for high-speed screening, accuracy in identification of nuclear materials, and relatively low cost and simplicity in design and operation. The advantages are achievable through use of ultra-compact superconducting accelerator technology applied to sources development, which can be tailored to produce multiple monoenergetic gamma rays and/or neutrons. Furthermore, monoenergetic sources coupled with the development of advanced radiation detectors and a new information science-driven approach for system design and data analysis have a potential to create unprecedented performance of the system in view of safety, efficiency and accuracy. The unique and innovative approach to the design is the enabling factor for future SNM detection technologies. Integration of the novel method of monoenergetic source generation through use of a new generation of ultra-compact accelerators with advanced imaging detectors has a potential for a paradigm shift in the ability to rapidly and accurately clear objects from nuclear threats. Moreover, this interdisciplinary work requires a broad combined expertize in the areas of compact hadron accelerators, monochromatic gamma-ray sources, detectors, and algorithms making our team particularly well-suited for the task. This research combines several new and high-risk ideas and, if successful, could bring about revolutionary advances in the methods to detect shielded SNM, with broad impacts and benefits to the welfare and security of the nation and society and promote the diversity and public understanding of science and engineering.

使用单色伽马射线对核威胁进行低剂量检查是一种检测屏蔽核材料（SNM）的新方法，其潜力有可能胜过当前使用的方法。我们正在采用的方法的主要优点是低剂量（20 MRAD），高速筛选的能力，识别核材料的准确性以及相对较低的成本和设计和操作的简单性。通过使用应用于来源开发的超导超导加速器技术，可以实现这些优点，该技术可以量身定制以生产多种单词伽玛射线和/或中子。此外，单核资源以及高级辐射探测器的开发以及用于系统设计和数据分析的新信息驱动的方法有可能在安全，效率和准确性方面创建系统的前所未有的性能。设计设计的独特而创新的方法是未来SNM检测技术的推动因素。通过使用新一代的超紧凑型加速器与高级成像探测器的新一代源代源生成的新方法的整合可能会导致能够快速，准确地清除核威胁的物体的能力范式转移。此外，这项跨学科的工作需要在紧凑的强子加速器，单色伽马射线来源，探测器和算法方面具有广泛的专业化，这使我们的团队特别适合这项任务。这项研究结合了几个新的和高风险的思想，如果成功，可以在检测屏蔽的SNM的方法上带来革命性的进步，并对国家和社会的福利和安全产生广泛的影响和利益，并促进对科学和工程学的多样性和公众的理解。
