Low temperatures enhance magnetic coercivity to overcome field strength limits, while HTS tapes, with high operating temperatures and critical fields, are widely used in high-field devices. Amid global helium shortages, developing liquid-helium-free cooling technologies has become a key trend. Utilizing its advanced light source facilities, NSRRC develops HTS magnets and cryogenic permanent magnet undulators, establishing key technologies in design, vacuum, thermal control, soldering, cooling, and measurement to promote diverse applications in scientific research and industry.

This program develops engineering technologies for cryogenic permanent magnet undulators and high-temperature superconducting (HTS) tapes, including magnet design, coil fabrication, soldering, cooling, temperature control, UHV environments, and measurement. These capabilities provide a foundation for advancing HTS applications in scientific research and industry.

HTS tapes exhibit superconductivity above 77 K with high critical fields, while cryogenic permanent magnets significantly enhance magnetic intensity, making them ideal for low-loss power transmission and high-field devices. Recently, HTS tech has been applied in power systems, energy storage, wind generators, medical accelerators, maglev trains, fusion energy, electron microscopes, and MRI.
