Abstract

With advancing demands in frontier science, maximizing both the magnetic field strength and diameter of superconducting magnets has become increasingly significant. However, as these parameters grow, the complexity of mechanical analysis for the magnet intensifies. Enhancing the structural stability of superconducting magnets through binding wires is a crucial challenge. Therefore, this paper proposes a numerical method to determine the requirements of binding layers. The finite element numerical method was used to comprehensively analyze the stress generated during the winding, cooling, and excitation of the 12T STM superconducting magnet being developed by the High Magnetic Field Laboratory of China (CHMFL). The required winding forces and number of binding layers for the magnet was determined, effectively improving spatial utilization and preventing shifts or quenching through elasticity theory. This method may also be applied broadly to the mechanical analysis and binding layer determination of other large-aperture, high-field superconducting magnets.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
