SuperMag New Energy Achieves Milestone Progress in Development of 25 T-Class High-Temperature Superconducting Toroidal Field Model Magnet
Recently, SuperMag New Energy has achieved two milestone progresses in the development of its 25 T-class high-temperature superconducting toroidal field model magnet: following the completion of R&D and testing of the first panel-type high-temperature superconducting single pancake coil, the company has initiated batch manufacturing of panel-type single pancake coils; meanwhile, the self-developed 24 cm² low-resistance detachable joint has completed prototype fabrication and performance testing in the liquid nitrogen temperature range, with an equivalent joint resistance of approximately 33 nΩ. These two progresses correspond to two critical aspects: stable manufacturing of single pancake coils and low-loss interconnection of multiple units. The project has advanced from the single-component process validation stage toward multi-pancake manufacturing and model magnet system integration. The single pancake coil is not an ordinary component in the model magnet, but rather a fundamental unit integrating conductor, panel structure, insulation, electrical connection, and testing interfaces. Each single pancake requires independent manufacturing and inspection, and also serves as the foundation for subsequent multi-pancake stacking, magnet excitation, and cryogenic operation.
