制冷机直接冷却的超导磁体系统进展

PROGRESS OF SUPERCONDUCTING MAGNET SYSTEM DIRECTLY COOLED BY CRYOCOOLER

与液氦浸泡冷却相比，制冷机直接冷却的超导磁体系统具有安全性好与操作维护方便等许多优点，特别是近年来在高温超导体和气体制冷机的研究方面出现了突破，大大加速了制冷机冷却技术的发展，得到了日益广泛的应用。

Compared with that cooled by immersion in a pool of liquid helium,the superconducting magnet system directly cooled by cryocooler has many advantages such as safety and easy operation,etc.In particular,in recent years,big breakthroughs have been won in the research of high Tc superconductor and gas cryocooler.These breakthroughs greatly speeded up the development of cryocooler cooling technology which has found more and more applications. This paper gives a review of the important progress in the research of cryocooler cooled superconducting magnet system in recent years.
