摘要： PURPOSE:To improve the mechanical strength of the title magnet and, at the same time, to improve the electric characteristics by uniformizing the stress distribution in the radial direction of a winding section by winding a double conduit conductor by a prescribed number of turns and preventing the occurrence of shearing force between the conductor and an insulating materiel. CONSTITUTION:A winding section 4 is constituted by housing a superconducting wire 6 in the first conduit 5 together with a coolant and winding a double conduit conductor 8 holding the first conduit 5 by a prescribed number of turns after the second conduit 7 is arranged so as to cover the outer peripheral part of the conduit 5. During the course of constituting the winding section 4, the stress distribution in the radial direction of the winding section 4 is made uniform and the occurrence of shearing force between the double conduit conductor 8 and an insulating material 9 is prevented by gradually increasing the thickness of the second conduit 7 in the radial direction from the inside diameter side to the outside diameter side of the winding section 4. Therefore, the mechanical strength can be increased and, at the same time, the electrical characteristics can be improved.
