にある。In the figure, the plasma is an annular vacuum vessel 2.
arises within. A winding frame 3 is provided along the vacuum vessel 2 to surround the vacuum vessel 2, a helical coil 4 is wound around the winding frame 3, and a guide 5 for guiding the helical coil 4 is provided between the helical coils 4. It is provided.
The helical coil 4 is tightened and fixed by a band 6. A plurality of toroidal coils 7 are provided around the outer periphery of the helical coil 4 along the vacuum vessel 2 at predetermined intervals. The outer periphery of the toroidal coil 7 is held by the support 8 and held in a predetermined position. In the conventional device configured in this way, the edge calcoil 4 is located close to the vacuum vessel 2.
Since the toroidal coil 7 is arranged around the outer circumference of the helical coil 4, the toroidal coil 7 is called the main coil and is an important coil for stably confining the plasma. It has become difficult to apply a magnetic field effective to confine the plasma 1 generated inside the container 2 to the plasma 1. In particular, the helical coil 4 uses a dedicated winding frame 3 as a core for winding, and this winding frame 3 is arranged between the vacuum container 1, the toroidal coil 7, and the helical coil 4, and the winding frame 3 The hemicoil 4 and the toroidal coil 7, especially the toroidal coil 7, must be placed at a position away from the plasma in the vacuum vessel 2 only in the space that is closed.
With the toroidal coil 7, it becomes difficult to apply a magnetic field to the plasma 1 that is effective for confining the plasma. In order to make the magnetic flux generated by these coils effectively act on the plasma, it is sufficient to increase the magnetic flux, but this does not effectively confine the plasma, and improvements in this point are strongly desired. The present invention has been made in view of the above points, and its purpose is to:
It is an object of the present invention to provide a nuclear fusion device that can stably and efficiently confine plasma by increasing the magnetic flux generated by the coil even if it has a helical coil.

能となり磁束を大きくする必要もなくなる。In this embodiment shown in the figure, a toroidal coil 9 is disposed close to the vacuum vessel 2, and a support 10 for supporting the toroidal coil 9 is disposed around the outer periphery of the toroidal coil 9. The lever 9 is supported on the inner peripheral side of the support 10. A plurality of toroidal coils 9 are arranged at predetermined positions along the annular vacuum vessel 2, and a plurality of supports 10 are similarly arranged corresponding to the toroidal coils 9. Furthermore, in this embodiment, a helical groove 12 for accommodating the edge calcoil 11 is provided on the outer periphery of the support 10.
is provided, and using this support 10, the hemical coil 11 is accommodated in the groove 12 of the support 10,
The edge calcoil 11 is supported and fixed by a band 13 from its outer periphery. The support 1 is arranged in an annular shape around the outer periphery of the vacuum vessel 2 and is placed in the electromagnetic field created by the toroidal coil 9 and the helical coil 11, so it is not possible to prevent the coil from being made of magnetic material such as metal. It is preferable to use a non-magnetic material, such as glass fiber reinforced plastic, because it disturbs the magnetic field and prevents a uniform magnetic field from acting on the plasma. In the structure shown in this embodiment, the toroidal coil 9, which plays a main role in confining the plasma 1,
Since it is provided on the outer periphery of the vacuum vessel 2 which can be close to the plasma, it is possible to confine the plasma effectively and efficiently, and there is no need to increase the magnetic flux.

き核融合装置に採用する場合には非常に有効である。In particular, since the support 1 for supporting the toroidal coil 9 also serves as support for the helical coil 11 and the helical coil 11 is housed in the groove 12 of the support 10, the support frame for the helical coil 11 is The helical coil 11 can be placed closer to the plasma 1 compared to a case where the helical coil 11 is provided separately, and the space can be used more effectively and the helical coil 11 can be placed closer to the plasma 1 compared to a case where the coil is provided separately. , the diffusion of the plasma 1 can be further prevented, magnetic flux can be effectively applied to the plasma 1, the plasma can be stably confined, and the configuration can be simplified. Furthermore, by forming the support 10 from a non-magnetic material, there is an effect that a uniform magnetic field can be applied to the plasma 1. According to the nuclear fusion device of the present invention described above, a plurality of magnetic fields are provided around the outer periphery of the vacuum vessel, which is configured in an annular shape and in which plasma is generated, surrounding the vacuum vessel. A toroidal coil that generates is arranged, a support for supporting the toroidal coil is provided on the outer periphery of the toroidal coil, and a hemline-shaped groove is provided on the outer periphery of the support, and the hemline coil is supported within this groove. Therefore, there is nothing that impedes the magnetic flux between the toroidal coil and the vacuum vessel, and the magnetic flux of the toroidal coil, which is the main coil for confining the plasma, can effectively act on the plasma. Moreover, since the support supporting the toroidal coil is used to support and fix the helical coil, magnetic flux can be applied to the plasma more effectively than when a support frame for the helical coil is provided separately. This makes it possible to confine plasma stably and efficiently without increasing the magnetic flux generated by the coil, making it extremely effective when used in nuclear fusion devices.
