PROGRESS OF SUPERCONDUCTING MAGNET SYSTEM DIRECTLY COOLED BY CRYOCOOLER

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.
