Abstract

PURPOSE:To allow stable winding of a coil while maintaining the control of tension and accurate positioning by a method wherein flat and angular dummy wires having the same diameter as that of a superconductive wire are lapped in two layers on the internal diameter inside and drawn out along the wire one by one. CONSTITUTION:A dummy band plate 7b is lifted up with winding bolt 9a to press the lower half of a superconductive wire 3. Then, the winding bolt 9b is loosened to draw out the dummy band plate 7a'. A superconductive wire 3c is preliminaliry placed at the position of the band plate 7a', and the lower half of the superconductive wire 3c is half fixed by applying pressure with a band plate 7a' by means of the bolt 9b. After that, the bolt 9a is loosened to draw out the band plate 7b', and the superconductive wire 3c is inserted into a specified position with a beating block 10, etc. under this condition. The superconductive wire 3c placed in the specified position is subjected to tension in the direction of 3b to maintain a accurate position, thereby allowing easy winding without loosening.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention is an electron storage system that uses an electron accelerator to store '1' particles at high energy! This article relates to a method of winding a dipole superconducting coil used in 1J.

[Technical background of the invention and its problems]

As the electron storage ring becomes smaller and has higher energy, it has become necessary to use a curved wheel-shaped twin-shaped deflection coil with high magnetic force using a superconducting image. As a conventional technology, there is a superconducting image straight-tube dipole deflection coil developed at Fermi Research Institute in the United States. In order to prevent quenching due to the high magnetic force exerted on the dipole deflection coil, the tension of the winding is carefully controlled, the coil is integrally molded with resin, and the coil is preloaded and fixed by applying pressure to the MR laminate. ing.

To eliminate the above-mentioned problems, a new attempt is made to use a curvature dipole coil (in which further agglomeration 'JR occurs).

[Purpose of the invention]

The object of the present invention is to provide a winding method that eliminates the various problems that occur with the transition from the straight cap type superconducting coil described above to the curved type superconducting coil, and ensures tension management and position accuracy control of the superconducting wire. With the goal.

[Summary of the invention]

This invention is a winding method for stably manufacturing a curvature dipole winding coil.
This is a method in which two rectangular dummy wires of approximately the same size as the superconducting wire are laminated on the inner diameter side, and the wires are wound while being pulled out sequentially to ensure tension control and position accuracy control.

〔Effect of the invention〕

This invention is for tension management of a curvature dipole winding coil.

It is possible to secure position accuracy control and stably manufacture coil winding using a simple method.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained in detail. In order to explain the present invention in detail, first, the process of manufacturing a dipole winding coil will be explained with reference to FIGS. 1 to 5. FIG. 1 shows an overall view of the winding frame on the winding machine.

A solder ring winding frame 1j11 is attached to the flat base 2 to regulate the shape of the coil. Superconducting wire (or normal i-conducting wire)
3 is the winding frame type 1. It is wound around the upper core 4 starting from 3a and continues to wind up to 3b.

The diagonal guides to prevent the coil winding from unraveling are 5a and 5b.

6a and 6b. Curvature type diatomic winding has slack on the inner diameter side, tension management and position'! Since it is difficult to ensure blueness control, two layers of dummy strips 7 are installed on the inner diameter side.
, 7b and built-in guides 8a, 8b to position and advance the winding.

The winding procedure will be explained with reference to FIGS. 2 to 5. First, as shown in FIG. 2, the dummy band plate 7b is pushed up using the hoisting bolt 9a, and pressure is applied to the lower half of the superconducting wire 3.

Next, slightly loosen the hoisting bolt 9b and remove the dummy strip plate 7a'.

The superconducting wire 3C is temporarily placed at the dummy band plate 73' that was removed in FIG. In Figure 4, wind up the wire again) 9b (- Apply pressure to the lower half of the temporarily placed superconducting wire 3C with the dummy band plate 7a' and semi-fix it.) Loosen the dummy band 9a. Remove plate 7b'.

In this state, the superconducting wire 3C is pushed into a fixed position using a pushing block 10 or the like.

The superconductor @3C placed in position in Figure 5 is 3 in Figure 1.
A predetermined tension is applied in the b direction, and positional accuracy can also be ensured. The outer diameter side is convex, making it easy to wind the coil without sagging. The dummy band plate 7 is generally made of a resin such as vinyl chloride, which has a low coefficient of friction and is flexible.
