"based on the parameters of three 100 m long iron-based superconducting tapes. They explored and perfected the process of coil development, and set up the test system of iron-based superconducting coil in high field... higher magnetic field using seven large-sized iron-based superconducting double pancake coils (DPCs) was demonstrated with promising results... generated central magnetic field strength 1.03 T in 20 T background field of WM3 water-cooled magnet surpassing previous record"
