中国科学院战略性先导科技专项（Ａ类）“先进核用材料研发与示范应用”项目四课题一“先进表征评价技术”2023年度课题年度工作报告

针对核用材料先进微观表征技术方法学研究，团队调研了多种先进表征技术，初步形成了材料表征和装置研发思路，为后续辐照损伤定量研究奠定了方法学基础。同时，团队积极协调同步辐射/中子谱学等大科学装置资源，面向核用材料的微结构表征需求，初步设计了相关的技术流程与实验方案。

For the methodological research on advanced microscopic characterization techniques for nuclear materials, the research team has investigated a variety of advanced characterization techniques and initially developed ideas for material characterization and apparatus development, laying a methodological foundation for subsequent quantitative studies on irradiation damage. Meanwhile, the team actively coordinated resources from large-scale scientific facilities such as synchrotron radiation and neutron spectroscopy, targeting the microstructure characterization requirements of nuclear materials, and initially designed relevant technical procedures and experimental schemes.
