Misaligned Analysis of the 15 T Magnet in Super-X Facility

Abstract

The Super-X facility for testing large size superconducting conductors is making significant progress. However, the magnetic force between two coils arises when the centers of their respective magnetic fields do not coincide. Coil misalignment is nearly unavoidable during the installation of magnets which will lead to this eccentric force. In particular, for suspended background magnet in Super-X facility, the eccentric force amplifies the stress on structural components, thereby potentially compromising the magnet's safe operation. Therefore, it is imperative to evaluate its impact on the structural components of the magnet. The pull rope structure of the background magnet is elaborated upon in this article, followed by the analysis of the electromagnetic force generated under different eccentricities of the magnet. Subsequently, the stresses on the structural components of the magnet with and without the pull rope structure are analyzed separately. The results demonstrate that the presence of a pull rope structure is crucial for withstanding magnet eccentricity. Thus far, it can be concluded that the mechanical performance of the magnet still meets the design requirements, taking into account coil misalignment.
