Abstract :
A conduction-cooled superconducting magnet was designed, fabricated and tested. A two-stage Gifford-McMahon (GM) cryocooler with the second-stage cooling power of 1.5 W at 4.2 K is used to cool the superconducting magnet from room temperature to 4.2 K. The superconducting magnet has the operating current of 105.5 A, the effective warm bore size of 250 mm, the maximum center field of 4.5 Tesla. The superconducting magnet will be used for the material processing. In this paper, the detailed design, fabrication and test are presented.
