ETER超导磁体设计与制备中的若干关键力学问题

超导磁体是目前正在研制和建造中的大型新能源装置即国际热核聚变实验堆（ITER）的核心部件，主要用于约束等离子体在有限环状空间内的流动，其力学研究直接涉及磁体结构安全性以及等离子体的稳定运行时间．我国承担着ITER超导磁体制备的任务包并取得成效，但由于磁体设计和制造涉及材料科学、力学、电磁学等多学科的交叉，同时也涉及超导复合线缆绕制与测试分析等一系列关键性技术问题，目前这一领域的研究不管是国内还是国外尚远未满足越来越多的大型超导科学装置的需求．本文主要介绍了ITER超导磁体从CICC导体的复杂制备到运行过程中所涉及的力学、超导物理等相互耦合作用的基础理论与实验研究方面的国内外现状以及存在的主要问题，其中也简要介绍了兰州大学电磁固体力学研究组在超导电磁系统相关方面的部分研究进展与成果等．

Review on some key issues related to design and fabrication of superconducting magnets in ITER

As one of the core components of new energy-resource installation of International Thermonuclear Experimental Reactor （ITER）, the superconducting magnet is designed and fabricated for constraining the plasma flow in a finite ring-shaped space. The related mechanical property and analysis are more important for stability of the superconducting magnet and stable runtime of the plasma in ITER. Our nation has been taking part in the international project of ITER and undertaking the procurement package of the fabrication of superconducting magnet. Since the design and fabrication of the huge superconducting magnet involve the multidisciplinary of material science, mechanics and electromagnetic science, as well as plenty of key technology issues in the process of superconducting composite conductor winding and measurements, the present progress in such research area conducted in both home and abroad is extremely lacking for the more and more demands of huge-sized superconducting magnets and equipments. The review presents some national and international progress of theoretical and experimental investigations and related multi-field coupling issues from the conductor fabrication to the operation about the ITER superconducting magnet. Some research progress and work of superconductivity mechanics conducted in group of the electromagneto-solid mechanics in Lanzhou University are also addressed briefly in the paper.
