A superferric design was chosen in which the magnetic field is shaped by an iron yoke. For the dipole magnets only the superconducting coils are in a cryostat. These magnets are manufactured by Elytt Energy (Spain). The multiplets, assemblies of quadrupoles and higher order multipole magnets, are completely immersed in a liquid Helium bath.
Along the direction of the magnet ends, the axial gaps of the single pancake coils increased sequentially by 1.89 mm. Compared to the superconducting magnet with fixed gaps, using the same length of superconducting tape (4813.42 m), the critical current and storage energy of the optimized superconducting magnet increased by 20.46% …

Producing such strong fields requires superconducting magnets, but all previous fusion magnets have been made with a superconducting material that requires frigid temperatures of about 4 degrees above absolute zero (4 kelvins, or -270 degrees Celsius). In the last few years, a newer material nicknamed REBCO, for rare-earth …
These materials also expel magnetic fields as they transition to the superconducting state. Superconductivity is one of nature's most intriguing quantum phenomena. It was discovered more than 100 years ago in mercury cooled to the temperature of liquid helium (about -452°F, only a few degrees above absolute zero).
