Abstract

PURPOSE:To improve dimensional accuracy and magnetic field performance by reducing the strain of a vessel by adopting a double structure of an inner coil vessel assembled by welding a thin member and an outer coil vessel assembled by mechanical coupling. CONSTITUTION:An inner coil vessel 2 is formed, in order to contain superconductive coil winding 1 and refrigerant, in a completely sealed structure by welding. Since the vessel 2 is thinly formed, even if it is assembled by welding, strain by welding is minimized. An outer coil vessel 3 is so formed of a thick metal plate member as to fixedly support the winding 1 durably against a generated electromagnetic force. The vessel 3 of the thick structure is assembled by mechanical coupling means, and no problem of strain by welding occurs. Thus, they can be mounted without strain due to welding to enhance dimensional accuracy and magnetic field performance.

As a conventional example of superconducting coil device, Japanese Patent Publication No. 6050329
Examples include those disclosed in Japanese Patent Publication No. According to this prior art, as shown in FIG. 1, a superconducting coil winding is housed in a coil container, a wedge member is driven between the superconducting coil winding and the coil container, and the superconducting coil winding is placed in the coil container. Structures in which conductive coil windings are fixed have been disclosed in the prior art. The coil container has the function of accommodating the superconducting coil winding and a refrigerant to maintain the winding at a predetermined cryogenic temperature, and the function of storing the strong electromagnetic force generated when the superconducting coil winding is excited. In contrast, it has the function of fixedly supporting the superconducting coil winding. Therefore, although the coil container has a single container wall in the illustrated example, it is formed with a considerably thick wall in order to achieve the latter function.

In the coil winding fixing structure of the conventional superconducting coil device described above, no consideration is given to the distortion of the coil container caused by welding when manufacturing the coil container. In other words, when a superconducting coil device becomes larger and the coil container structure described above is adopted and the coil container is hermetically sealed by welding, the thickness of the container wall is considerably large, so it is difficult to assemble the coil container. During welding, the wall of the coil container is distorted, which deforms the superconducting coil winding housed and fixed inside the coil container, resulting in a problem that a predetermined designed magnetic field performance cannot be obtained.

In FIG. 1, 1 is a ring-shaped superconducting coil winding, 2 is a ring-shaped inner coil container located inside, and 3 is a ring-shaped outer coil container located outside. As is well known, the superconducting coil winding 1 is constructed by arranging a large number of basic coil windings with gaps between them.

An inner coil container 2 accommodating the superconducting coil winding 1 is formed of a thin metal plate. The inner coil container 2 accommodates the superconducting coil winding 1 and the refrigerant. Since the refrigerant must be contained, the inner coil container 2 is formed into a completely sealed structure using welding.

In order to satisfy these conditions, the outer coil container 3 is formed with a thick wall structure.
