Abstract

We have succeeded in constructing a superconducting permanent magnet system capable of generating 3.2 T by melt-processed bulk superconductors. The trapped field was measured in the open gap between the magnetic poles settled face to face after the pulsed-field magnetization technique called the 'IMRA' method operated at 38 K. A novel face-to-face field generator has been composed by a pair of wide magnetic poles installed with seven bulk superconductors arranged in one plane. The magnetic pole is 150 mm in diameter. The performance of the magnetic field by the field cooling method by a 5 T conduction-cooled superconducting solenoid reached 1.4 and 0.9 T at the centre of the vacuum chamber surface and at the centre of the open space between the magnetic poles with a gap of 34 mm. The intense magnetic fields are investigated for application in various industries such as the magnetic separation technique and so on in the Iwate CREATE (Collaboration of Regional Entities for the Advancement of Technological Excellence) project supported by the Japanese government.
