Superconductive magnet

Abstract

Abstract PURPOSE:To obtain a compact and stable superconductive magnet by a method wherein insulating materials are fixed to the circumference of compound superconductive conductors and lubricating materials are applied to the outsides of the insulating materials or low friction spacers are positioned for winding. CONSTITUTION:In layers composed by winding compound superconductors, interlayer insulating materials 3, such as glass fiber inserted epoxy resin, cloth inserted phenol resin, are buried in and fixed to the suitable places at the layer sides of stabilizing materials 2 and spacers 4 are inserted and positioned between the spaces facing these interlayer insulating materials 3. Electromagnetic force acting on the layers is transferred to the conductors through the interlayer insulating materials 3 and the spacers 4. Meanwhile, in the spaces between conductor turns, interturn insulating materials 5 are fixed to the insides of the turns of the stabilizing materials 2 and spacers 6 such as ethylene tetrafluoride having low friction coefficient are inserted and positioned at the middle of the interturn insulating materials 5. This does not generate friction heat involved in conductor transition on the surfaces of the conductors and a compact and stable magnet can be obtained.
