変わるように円上に配置する。この配置では多極磁場の
極数は永久磁石の個数に等しい。In a conventional configuration of a permanent magnet that generates a multipolar magnetic field, the permanent magnets are arranged in a circle so that the direction of magnetization alternates along the radial direction or the circumferential direction. In this arrangement, the number of poles of the multipole magnetic field is equal to the number of permanent magnets.

ラズマに対する安定化効果を高めるために多極磁場の極
数を増加するとそれに応じてプラズマ容器の周囲に並ぶ
永久磁石の数が多くなるのでプラズマ診断装置を装着す
るのが困難になる。(Problem to be solved by the invention) Plasma diagnosis is essential for plasma improvement, but in order to increase the stabilizing effect on the plasma, increasing the number of poles of the multipole magnetic field will cause the number of poles to line up around the plasma container accordingly. Since the number of permanent magnets increases, it becomes difficult to attach the plasma diagnostic device.

Solved by magnetic field generator.

場の極数を減することなく永久磁石の数が半減される。Effect) The greater the number of poles in a multipolar magnetic field, the greater the stabilizing effect on plasma. When multiple permanent magnets arranged in a circle are magnetized in the circumferential direction and in the same direction, these permanent magnets strengthen each other and become equivalent to other permanent magnets existing between them. The number of poles is doubled. That is, the number of permanent magnets is halved without reducing the number of poles of the multipolar magnetic field.

できる。(Effects of the Invention) According to the present invention, since a large space is created between the permanent magnets, not only can a plasma diagnostic device be attached, but also a cooling pipe can be installed to process the heat from the plasma flowing along the lines of magnetic force. Space can be easily secured. The number of lines of magnetic force per permanent magnet penetrating the plasma is approximately 1.5 times that of the conventional method, which is economical. Since the number of poles that can be allowed in the same space can be doubled compared to the conventional method, breakthrough performance can be expected.
