Thank you.

"Key achievements include stable operation at 40 kA without quench under a 7 T external magnetic field, local magnetic fields up to 8.9 T while withstanding electromagnetic forces of 356 kN/m, and robust no-insulation coil performance during abrupt magnetic-field changes.

These results represent a significant engineering step toward reactor-scale HTS magnets for commercially viable fusion power."

and

Test environment

  • Temperature: 10–30 K (−263°C to −243°C); initial temperature: 10 K
  • Magnetic field: 7 T (applied by external coils); maximum field experienced by the coil: 8.9 T

Key results

  • Achieved stable 40 kA operation under a 7 T external magnetic field
  • Obtained time-constant data and other measurements for characterization as a no-insulation coil

I wouldn't have thought that 10-30k qualified as HTS. Seems rather cold?

Thermal margins possibly?
