DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nuclear fusion device, and particularly to a structure of a transition portion between boroidal magnetic field coils.

A nuclear fusion device creates a magnetic field wall in a vacuum container and confines plasma within the magnetic field wall, and there are various types depending on the method of generating this magnetic field. For example, in a torus-shaped fusion device, a plurality of toroidal magnetic field coils are wound around the vacuum vessel to apply a magnetic field along the circumference of the vacuum vessel, creating a plasma inside the vacuum vessel. Although the plasma is completely confined, various voloidal magnetic field coils placed concentrically with the vacuum vessel generate a circular magnetic field to control the plasma position.

By the way, in a small toroidal fusion device of this type, the voloidal magnetic field coil 1 is usually placed outside the toroidal magnetic field coil 3 that completely surrounds the vacuum vessel 2, as shown in FIG. be. In addition, in the figure,
The C-C line indicates the center of the torus. Therefore, since the voloidal magnetic field coil 1 can occupy a relatively large space, there is no need to pay special consideration to its structure.

However, when it comes to a large tube that generates a strong magnetic field, the structure shown in FIG. 1 increases the size of the entire device, which is not a good idea from both a structural and cost standpoint.

Therefore, as shown in FIG. 2, the space between the vacuum container 2 and the toroidal magnetic field coil 3 is effectively used to arrange all the voloidal magnetic field coils 1i1B. If they are arranged in the same way, the following spatial problems arise.

In other words, various poloidal magnetic field coils are arranged according to their respective purposes in consideration of the magnetic field distribution for plasma control, but in order to make effective use of space, in the same type of poloidal magnetic field coils, for example, from coil IN to It is sequentially connected to coil IB. FIG. 3 is an enlarged perspective view of this connecting portion, and FIG. 4 is a view taken along arrow A in FIG. 3. As can be seen from these figures, at the transition section X where the ends la and lb of each coil IA and IB are connected by the crossover wire 4, the height dimension is 1 tera-y compared to the other sections. If the unwinding wire 5 for canceling the unnecessary magnetic field caused by the current at the transition section is also considered, an extra space corresponding to the height of about two turns is required. In other words, at the transition section X between each coil, at least one
Because extra space is required for the height of the tan
It is difficult to effectively arrange the poloidal magnetic field coil 1 in a narrow space between the vacuum vessel 2 and the toroidal magnetic field coil 3, and there is a drawback that the control characteristics by the coil 1 are deteriorated.
