Abstract
We have succeeded in constructing the world's first superconducting permanent magnet system capable of generating a strong magnetic field of 3.15T using a pair of meltprocessed bulk superconductors as trapped field magnets. The magnetic field was measured in a 2mm open gap between the magnetic poles set face-to-face after magnetization by the pulsed-field magnetization (“IMRA”) method operated at 35K. The strong field generator is composed of Smbased 123 bulk superconductors, vacuum pumps, pulsed-field coils and GM-cycle refrigerators with compressors. The performance of this compact field generator exceeds those of conventional rare earth magnets or large-scale electromagnets by far. Various application candidates for the strong field generator, such as magnetic separation systems, motors/generators, and a magnetron sputtering apparatus, are proposed in this report.
