とが多い。[Detailed Description of the Invention] [Technical Field of the Invention] Superelectric wires constituting superconducting magnets are often wound without the surface of the wire being covered with an insulating material, either to improve cooling inertia or due to constraints in the manufacturing process. It often forms a broken wire coil. In such cases, it is necessary to electrically insulate the wires by 1%, and generally the wires are wound with an insulating spacer sandwiched between the wires.

いことが明らかになっている。In order to operate a superconducting magnet stably, it is necessary to remove disturbances that destroy the superconducting state, but most of the disturbances that make a superconducting magnet unstable are due to local movements of the coils of the superconducting magnet. . However, the superconducting wires that carry the current that make up the superconducting magnet try to move to a stable position due to the strong magnetic force generated by the magnet's magnetic field. At this time, super η1. The conductor is sandwiched between insulating spacers, which generates heat between the conductor and the insulating spacers. It has become clear that this heat generation often destroys the superconducting state.

触面との間には明確な関係が確定されていなかっブこ。By the way, glass fiber reinforced plastic (hereinafter referred to as FRP), which has excellent mechanical strength, is widely used for the insulating spacer. Most of the FRP used for spacers is formed by laminating glass cloth impregnated with uncured resin and then heating and pressing the layers. For this reason, significant anisotropy appears in the physical properties between the lamination direction and the other direction, and this example also applies to the coefficient of friction. That is,
The coefficient of friction for movements in contact with the surface of the glass cloth is small, and the coefficient of friction for movements in contact with the surface perpendicular to the surface of the glass cloth is very large. F for conventional spacer
The way RP was used was determined by the cheap availability of the material, and no consideration was given to the friction coefficient, so there was no clear separation between the stacking direction of the glass cloth of the spacer and the contact surface of the superconducting wire. The relationship has not been confirmed yet.

It is necessary to provide insulating spacers and installation methods for superconducting magnets that are in contact with each other and are unlikely to cause conductive breakdown.

を得ることが出来る。1. To the FRP spacer and super installed as above. 'The coefficient of friction between the conductive wires is much smaller than in the case shown in Figure 1, so the amount of heat generated by the movement of the superconducting wire to a stable position is also small, making it a superconductor where nπ haze 11 is less likely to be breached. You can get magnets.
