Collaborative Research: ARI-MA: Nuclear Data Measurements Using Gamma Rays and Radiation Detector Development

该合同的主要目标是对国内核探测办公室（DNDO）感兴趣的锕系元素和其他材料进行NRF截面测量。这项工作将在三角大学核实验室（TUNL）使用高强度伽玛射线源（HIGS）进行。开发和操作伽马射线束检测系统所需的数据包括用于同位素鉴定的核共振荧光（NRF）数据和用于鉴定裂变材料的光子中子反应数据。此外，这些数据对于用于分析爆炸前和爆炸后材料的核法医技术的应用也很重要。这项研究将由两家机构的研究小组合作进行：杜克大学和北卡罗来纳农工州立大学（NC A&amp；T）。其他合作者包括来自劳伦斯利弗莫尔国家实验室、洛斯阿拉莫斯国家实验室和太平洋西北国家实验室的物理学家。这项研究将在以下四个方面为DNDO的使命作出贡献：(1)与开发货物非侵入式检查技术以降低辐射威胁风险相关的科学；(2)与开发对引爆前和引爆后材料进行核取证能力相关的科学；(3)新型辐射探测器技术的科学与工程；以及(4)开发对DNDO使命和履行国土安全部职责重要的新技术所需的科学人力。该项目将为几所大学的研究生和本科生提供研究机会，包括杜克大学、北卡罗来纳州a&t州立大学、北卡罗来纳州立大学和佛罗里达a&m大学。该研究将在TUNL教育丰富的环境中进行，该环境目前约有45名博士学位研究生。由于TUNL的研究小组通常很小，学生们可以以学徒的方式与教师和博士后密切合作。北卡罗来纳农工学院的研究小组和佛罗里达农工大学的学生的参与还有一个额外的好处，那就是让这些传统黑人大学的学生在使用前沿粒子和伽马射线探测技术以及开发与解决高度优先的国家安全问题相关的实验技术方面获得经验。

The main goal of this award is to make NRF cross-section measurements on actinides and other materials of interest to the Domestic Nuclear Detection Office (DNDO). This work will be carried out using the High Intensity Gamma-ray Source (HIGS) at the Triangle Universities Nuclear Laboratory (TUNL). Among the data needed for developing and operating gamma-ray beam inspection systems are nuclear resonance fluorescence (NRF) data for isotope identification and photoneutron reaction data for identifying fissile materials. In addition, these data are important for applications in nuclear forensic techniques applied to analyzing pre-detonation and post-detonation materials. The research will be carried out by a collaboration of research groups from two institutions: Duke University and North Carolina A&T State University (NC A&T). Other collaborators include physicists from Lawrence Livermore National Laboratory, Los Alamos National Laboratory and Pacific Northwestern National Laboratory. This research will contribute to the mission of the DNDO in four categories: (1) science relevant to developing technologies for non-intrusive inspection of cargo to reduce risk of radiological threats, (2) science important for developing capabilities for performing nuclear forensic on pre-detonation and post-detonation materials, (3) science and engineering of novel radiation detector technologies, and (4) the scientific workforce needed to develop new technologies important to the mission of DNDO and to carry out the duties of the Department of Homeland Security. The project will provide research opportunities for graduate and undergraduate students at several universities including Duke University, NC A&T State University, NC State University and Florida A&M University. The research will be conducted in the educationally rich environment at TUNL which currently has about 45 PhD degree graduate students. Because research groups at TUNL are typically small, the students have the benefit of routinely working closely with faculty and postdocs in an apprenticeship style. The involvement of the research group from NC A&T and with students at Florida A&M have the added benefit of giving students at these Historically Black Universities experience with using leading edge particle and gamma-ray detection technologies and developing experimental techniques that are relevant to addressing high-priority national security issues.
