摘要:

回顾并总结了低温制冷机传导冷却的超导磁体系统的发展历程和最新研究进展.与传统的液氦浸泡冷却方式不同,低温制冷机传导冷却系统主要依靠低温下固体之间的热传导对超导磁体线圈进行冷却.基于小型低温制冷机的研究进展,集中讨论超导磁体中的制冷机传导冷却系统;结合传导冷却的超导磁体应用,讨论传导冷却中低温制冷机性能、低温恒温器传热以及加速冷却等技术要点,对低温制冷机传导冷却磁体系统的发展进行了展望.

Abstract:

A review of recent advances and research of cryocooled superconducting magnetic system was given. Cryocooled superconducting magnet coils are cooled by thermal conduction between solids in low temperature, compared to the convective heat transfer in liquid helium bath. The research of conduction cooling system in superconducting magnet was discussed based on the development of cryocooler. Typical designs of conduction cooling systems were illustrated and compared. Key technical issues about cryocoolers, heat transfer in conduction cooled coils and cool down time reduction were discussed. The development tendencies of the cryocooled superconducting magnetic technology were forecasted.
