密歇根州立大学即将建立的稀有同位素束设施（FRIB）提供了一个获得世界上一些最专业的科学资源的新机会：放射性同位素。随着FRIB完成其提供稀有同位素束的基础科学使命，将形成过量的有用放射性同位素。为了使FRIB束达到高纯度，许多同位素被丢弃和未使用。如果被收集，这些未使用的同位素可以用于从医学治疗和诊断到核安全等各种应用的新研究。鉴于FRIB将有能力创造约80%的所有可能的原子核，FRIB的收获将为获得基础和应用科学研究中感兴趣的大量同位素提供快速途径。为了充分利用这一机会，需要进行基础设施投资，以收集和纯化未使用的同位素。对FRIB同位素收获的投资将为关键同位素应用的开发提供强大的资源。2010年，美国能源部核物理科学办公室主办了第一届“FRIB同位素收集研讨会”，召集来自不同领域的研究人员讨论同位素收集的科学影响和技术可行性。在首次会议之后，组织了一系列两年期讲习班。2016年在密歇根州立大学举行的第四次研讨会上，社区选择准备一份正式文件来展示他们的发现。本报告是工作组的产出，其中吸收了广泛的科学专家的意见和讨论。
The upcoming Facility for Rare Isotope Beams (FRIB) at Michigan State University provides a new opportunity to access some of the world's most specialized scientific resources: radioisotopes. An excess of useful radioisotopes will be formed as FRIB fulfills its basic science mission of providing rare isotope beams. In order for the FRIB beams to reach high-purity, many of the isotopes are discarded and go unused. If harvested, the unused isotopes could enable new research for diverse applications ranging from medical therapy and diagnosis to nuclear security. Given that FRIB will have the capability to create about 80% of all possible atomic nuclei, harvesting at FRIB will provide a fast path for access to a vast an ay of isotopes of interest in basic and applied science investigations. To fully realize this opportunity, infrastructure investment is required to enable harvesting and purification of otherwise unused isotopes. An investment in isotope harvesting at FRIB will provide a powerful resource for development of crucial isotope applications. In 2010, the United States Department of Energy Office of Science, Nuclear Physics, sponsored the first 'Workshop on Isotope Harvesting at FRIB', convening researchers from diverse fields to discuss the scientific impact and technical feasibility of isotope harvesting. Following the initial meeting, a series of biennial workshops was organized. At the fourth workshop, at Michigan State University in 2016, the community elected to prepare a formal document to present their findings. This report is the output of the working group, drawing on contributions and discussions with a broad range of scientific experts.
