この発明は超電導線を巻回して成る超電導マグ

れている。 Conventionally, superconducting magnets are constructed by winding a superconducting wire around a core or bobbin made of metal such as stainless steel, copper, or aluminum alloy.
Since it is necessary to electrically insulate between the superconducting wire being wound and the metal winding frame, a sheet of mylar, nylon, etc. is wrapped around the outer circumference of the winding frame, and the superconducting wire is wound on top of it. There is. Insulation between the collar at the end of the winding frame and the winding wire is achieved by gluing a thin plate of Bakelite, Teflon, glass, epoxy resin, or the like.

る。 However, in such conventional structures, the sheet of Mylar or other material wrapped around the outer circumference of the reel often ruptures due to the pressure of the multi-layered winding wire under tension, and as a result, insulation may become impossible. be. Furthermore, a thin insulating plate that is attached as a spacer between the collar of the winding frame and the winding wire has the disadvantage that the adhesive may peel off at extremely low temperatures, or it may be deformed due to a difference in shrinkage rate from the material of the winding frame itself.

することにある。 The purpose of this invention is to eliminate these drawbacks by applying polytetrafluoroethylene or its copolymer (trade name: Teflon) to the surface of the main body made of aluminum or aluminum alloy that comes into contact with the superconducting wire being wound. An object of the present invention is to provide a winding frame for a superconducting magnet that is coated with a Teflon coating (hereinafter referred to as Teflon coating).
以下この発明を添附図面を参照してさらに説明

ている。 The drawings show an embodiment of the present invention in cross-sectional view,
Reference numeral 1 denotes a winding frame body made of aluminum or aluminum alloy, and on the outer circumferential surface 2 and inner surfaces 3a, 4a of the ends 3, 4 of this winding frame body 1, for example, Japanese Patent Publication No. 51-1654 or Japanese Patent Publication No. 52 A Teflon coating 5 formed by Taflam coating described in Japanese Patent No. 39059 is applied, and a superconducting wire 6 is wound thereon to constitute a superconducting magnet.

化を妨ぐことができる。 With this structure, in the superconducting magnet spool of the present invention, the surface of the Teflon coating 5 has a very small coefficient of friction, so that the electromagnetic force generated during excitation of the superconducting magnet prevents the winding and the spool from collapsing. As a result, it is possible to reduce the deterioration of the characteristics of the superconducting magnet, that is, the quench phenomenon in which the superconducting magnet changes to a normal conductive state due to a local temperature increase due to frictional heat. Furthermore, by increasing the thermal conductivity between the winding frame and the winding wire by the Teflon coating, the cooling effect can be increased, thereby preventing the properties of the superconducting magnet from deteriorating.

である。 As explained above, the superconducting magnet winding frame according to the present invention does not use spacers such as mylar sheets for insulation, Teflon, Bakelite, etc. as in the past, so it not only does not have the above-mentioned disadvantages caused by them, but also has the above-mentioned problems. As explained above, it is useful for preventing deterioration of the characteristics of superconducting magnets.
