Description
Compact high-temperature superconducting (HTS) trapped field magnets hold great potential for advanced industrial/research equipment, medical devices, and electrified transportation, offering unique advantages over conventional permanent magnets and electromagnets. While superconductors use zero electrical resistance to sustain high currents and generate substantial fields, traditional HTS bulk and stack structures are constrained by geometric limitations, mechanical robustness, and scalability. With advancements in 2G HTS coated conductors, there is growing interest in utilizing these tapes to develop large and stable trapped field profiles. This presentation explores innovative magnetization mechanisms and design optimizations for HTS trapped field magnets based on 2G HTS tapes, focusing on HTS-stacked ring magnets, hybrid HTS-stacked ring designs, their mechanical stress responses, and trapped field closed-loop HTS coils under field cooling magnetization. By addressing these challenges, we aim to advance the development of compact, portable, and high-performance HTS magnets for applications in scientific research, advanced medical devices, maglev transportation and HTS machines.
