High-temperature superconductors (HTS) are indispensable for producing magnetic fields exceeding 20 T, a subject that has attracted substantial research efforts in recent years. This study aims to develop a conduction-cooled all-HTS magnet capable of generating a 20 T magnetic field with a 50 mm room temperature bore. The magnet has been designed to operate at a maximum temperature of 20 K...

This work presents a graded parallel-wound (GPW) coil technique for high temperature superconductor (HTS) magnet consisting of multiple pancake coils. The coil is wound by parallel-stacked HTS tapes, all the coils are connected in series, so that they have a same transport current. The key idea is to assign number of parallel-stacked tapes to pancake coils on different position of the magnet:...

The central magnetic field of current all-superconducting hybrid magnets used in engineering applications is limited to below 40 T, primarily due to challenges such as screening-current-induced stress (SCIS)and high background magnetic field. SCIS significantly impacts the electromechanical performance of insert high-temperature superconducting (HTS) coils, particularly under high background...
