Description
【発明の詳細な説明】 〔発明の技術分野〕 この発明は、超電導装置に関する。[Detailed description of the invention] [Technical field of invention] The present invention relates to a superconducting device.
最近超電導装置は大型化と共に多方面に利用さ

Recently, superconducting devices have become larger and are being used in a variety of fields, and research in various fields is progressing.

に冷媒の蒸発量が激しく使用不可能及び爆発の危
険性も含んで重要な箇所である。 The cryogenic container in which the superconducting coils are housed uses liquid helium as a refrigerant, so the outer periphery of the container is vacuum insulated and the amount of heat intrusion is kept to a minimum, resulting in problems such as the brittleness of the material at low temperatures and the generation of high stress due to electromagnetic force. This is an important location because the conditions overlap and harsh usage conditions result in the container breaking, refrigerant leaking into the vacuum tank, reducing the degree of vacuum, and the amount of refrigerant evaporating so much that it becomes unusable and poses the risk of explosion.

が大きいため、強力に押える必要がある。 Therefore, regarding the method of tightening and installing superconducting magnet devices, etc., if the force transmission and sealing are performed at the same location at the temperature of the cryogenic container (-200°C or less), the welded parts will be extremely damaged due to the cryogenic temperature. It becomes brittle and cracks occur due to stress, which can cause leaks. In particular, superconducting magnets have a large electromagnetic force, so they must be held down strongly.

を最小限に決める必要があり、応力的にも厳しさ
を増している。 However, in terms of performance, it is necessary to set the safety factor of the member to the minimum in relation to the amount of heat penetration, and the stress is also becoming more severe.

With the superconducting device according to the invention, the force of the superconducting coil acts parallel to the axis of the bolt, and as a result acts only at right angles to the side plate. As a result, no force is applied to the side plate in the direction in which it contacts the superconducting coil, that is, in the parallel direction of the side plate, so no force is applied to the seal, and a complete seal is therefore possible. It has excellent effects.
