44.86 T Magnetic Field Achieved with "Pocket-Type" High-temperature Superconducting Coil
Recently, a research team led by KUANG Guangli and JIANG Donghui from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science, Chinese Academy of Sciences (CHMFL), successfully developed a “pocket-type” high-temperature superconducting (HTS) coil. The coil, wound with domestically produced REBa₂Cu₃O₇₋ₓ (REBCO) tapes, generated 28.20 T at zero field in a liquid helium bath and produced an additional 10.36 T inside the 34.5 T steady-state magnetic field of the WM5 water-cooled magnet. Together, the system achieved a record combined magnetic field of 44.86 T.
