SUPERCONDUCTING PERMANENT MAGNET

WIPO Patent Application WO/2004/097865

A1

A strong magnetic field generator generating a wide magnetic field space by exciting bulk superconductors as pseudo permanent magnets. The superconducting permanent magnet (11) comprises magnetic pole assemblies (13) each holding a magnetic pole (22) formed by arranging a plurality of superconducting bulk bodies (21) side by side in a vacuum vessel (15) in a thermally insulated state, a frame (12) holding at least the magnetic pole assemblies (13) in a desired orientation and movable while the magnetic pole assemblies (13) are mounted thereon, refrigerating sections (29) of refrigerating machines (18) fixed to the magnetic pole assemblies (13), and vacuum pumps fixed to the magnetic pole assemblies (13) through vacuum piping. The superconducting permanent magnet (11) is characterized in that each magnetic pole (22) in the vacuum vessel (15) is secured through a heat insulating resin based structural material (23) to the flange of the magnetic pole assembly (13) to which the vacuum vessel (15) is secured.
