を防止するためのライナ７が配置されている。 In a torus-type nuclear fusion device, a plasma 1 is confined within a vacuum vessel 2, as shown in FIG. The vacuum vessel 2 is constructed by alternately arranging thick ring parts 3 and bellows parts 4 in the torus direction, and around them are a toroidal magnetic field coil 5 and a poloidal magnetic field coil for generating and maintaining plasma. 6 are arranged respectively. Further, a liner 7 for preventing radiant heat from the plasma 1 is arranged on the inner surface of the vacuum container.

溶融して、穴があく虞れがあつた。 Incidentally, when plasma is generated or extinguished, an induced current flows in the vacuum vessel, but as mentioned above, the vacuum vessel is composed of the thick ring 3 and the bellows part 4, which is a high resistance part. 4, a high voltage is generated between adjacent thick rings 3. Moreover, this high voltage is very likely to be discharged in the torus direction between the liners at the upper part of the bellows part due to the toroidal magnetic field B t directed in the torus direction of the vacuum vessel. For this reason, in the conventional structure shown in FIG. 2, there was a risk that electric discharge would occur between the adjacent liners 7A and 7B, and that the bellows portion 4 would melt due to the arc generated during this electric discharge, creating a hole.

れて、ベローズ部４が破損される虞れがある。 In addition, in order to prevent the occurrence of such discharge between adjacent liners, it is conceivable to provide a sufficient gap between adjacent liners 7A and 7B, as shown in FIG. This adjacent liner 7A, 7
Since the bellows part 4 is directly irradiated with high-temperature plasma through the gap between B, there is a risk that the bellows part 4 will be heated by this radiant heat and be damaged.
本発明の目的は、上記した従来技術の欠点を除

アークからベローズ部を効果的に保護し得るトー
ラス型核融合装置用真空容器を提供するにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a vacuum vessel for a torus-type nuclear fusion device that can effectively protect a bellows portion from radiant heat of plasma and discharge arc between adjacent liners, while eliminating the drawbacks of the prior art described above. .

る。 In order to achieve this object, the present invention is characterized in that a predetermined gap is provided between adjacent liners, a bellows cover is disposed astride between the liners so as to cover the gap, and this cover is supported by the bellows portion. shall be.
以下、本発明の一実施例を第４図について説明
する。 An embodiment of the present invention will be described below with reference to FIG.

れている。 In this embodiment, adjacent liners 7A and 7 are supported by each thick ring portion 4 via a liner support 8.
B are arranged with a sufficient gap. Also,
These liners 7A and 7B are placed so as to cover this gap.
The bellows part 4 is straddled between the liners 7A and 7B.
A bellows cover 10 is arranged on the side and is supported on the intermediate ring 9 via a bellows cover support 11.

ズ部４が溶融されることもない。 In this way, since a sufficient gap is provided between adjacent liners 7A and 7B, these liners 7A and 7B
Since no discharge occurs between 7B and this gap is covered with the bellows cover 10,
It is possible to prevent the bellows portion 4 from being heated by the radiant heat of the plasma. Further, even if a discharge occurs between the adjacent liners 7A and 7B, the arc caused by the discharge is blocked by the bellows cover 10 and does not directly hit the bellows portion 4, so that the bellows portion 4 will not be melted.
