る嫌いがあつた。 Therefore, in conventional large torus-shaped magnetic field generating coils, when two pancake-shaped coils are combined into one block, the pancake-shaped coil usually has a large manufacturing error during the winding process.
The error in the winding dimension of the two pancake-shaped coils is adjusted to the dimension of the larger winding one, and an insulator is attached to the smaller winding end to absorb the dimension, and a reinforcing ring is provided on the outside of this. . That is, the inner circumference of the reinforcing ring is machined to match the larger of the two pancake-shaped coils. In addition, to adjust the position between multiple coil blocks, install an insulator to absorb dimensions between the center column and the outer periphery of the reinforcing ring so that the outer periphery of the reinforcing ring is on a concentric circle from the center column. This is done by However, with this method, there is a large difference in the spring constant of two pancake-shaped coils in the same coil block due to the presence or absence of the above-mentioned size-absorbing insulator against the strong electromagnetic force directed toward the center column. I didn't like that the magnetic centers of the two pancake-shaped coils would shift significantly. In addition, in this case, the magnetic center of each coil block is displaced differently with respect to the outer ring of each coil block, so the magnetic center of the entire magnetic field generating coil does not form one circumference around the central column. , especially for fusion devices,
There was a concern that the stability of the plasma generated in the magnetic field would decrease.

核融合装置用コイルを提供するにある。 The present invention has been made in view of the above points, and its purpose is to reduce the non-uniformity of the magnetic field caused by manufacturing errors of the coil block, and to increase the stability of the plasma generated in the magnetic field. To provide coils for nuclear fusion devices.

ものである。 In the present invention, the inner diameter of the outer ring is machined to match each pancake-shaped coil so that the magnetic centers of the two pancake-shaped coils coincide,
Both pancake-shaped coils are held directly by the reinforcing ring against the strong electromagnetic force directed toward the center column, and the magnetic center can be adjusted with other blocks by using the outer periphery of the reinforcing ring or the legs. The desired purpose is achieved by cutting or overlaying so that the magnetic center of each block is on one circumference centered on the central pillar.
