According to reports, with a "cross-temperature hole" structure of the superconducting magnet with a split gap of 134mm electromagnetic structure, the coil maximum magnetic field of 13.5T, split gap between the coil electromagnetic attraction of up to 235 tons. In order to overcome the influence of the huge electromagnetic force on the superconducting performance of the superconducting gap, the mechanical structure and heat transfer structure of the superconducting magnet are optimized, and the optimal design scheme of the electromagnetic - stress - heat transfer structure is obtained. The cooling load of the superconducting magnet system is 1 ton, and the cooling load of the superconducting magnet system is reduced to 3.8K ultra-low temperature by the conduction cooling technology, which ensures the stable operation of the superconducting magnet system and get rid of the superconducting magnet System on the liquid helium, liquid nitrogen and other dependence.
Researchers have pointed out that large-caliber high-field superconducting magnets with "cross-over-temperature" structure not only provide users with large magnetic field application space, but also can provide conditions for real-time observation of sample test process, Materials processing, magneto-optics and magnetochemistry.
Recently, the system has passed the expert group of test acceptance, the indicators have reached the design requirements. China University of Science and Technology Institute of the successful development of large-caliber "cross-temperature hole" high field superconducting magnet system, marking the complex structure of high-field superconducting magnet design and manufacturing technology into the international advanced ranks.
