PURPOSE:To simultaneously assemble the coil for a magnetic sensor and an insulator by providing the coil for the magnetic sensor at the inner fringe of the insulator installed between pancake superconductive coils. CONSTITUTION:On the outer circumference of a drum 3, a pancake superconductive coil 13 and a circular disk type insulator 15 with holes are concentrically installed alternately to the direction of the axis. Among the insulators 15, at least one, e.g., in this case, the central insulator 15A provides a coil 9 for constituting a magnetic sensor adjacent to the inner fringe. For this reason, assembling of the coil 9 and the insulator 15 is carried out simultaneously and the assembling works are contrived to be simplified. |
