HYPERION's toroidal-field coils are D-shaped windings of REBCO high-temperature superconductor that produce the main confining field, reaching 16.84 T at the conductor. Their shape minimises bending stress, and a robust case and intercoil structure contain the enormous Lorentz forces.
Common questions
The breeder, HYPERION. They are its main confining magnet, D-shaped REBCO windings reaching 16.84 T at the conductor. The linear burner has no toroidal field — it confines its plasma in a straight solenoid instead.
The geometry is conventional tokamak practice, but the REBCO high-temperature-superconductor construction at 16.84 T is at the field frontier. Kronos maps the conductor, joints and structure in its open REBCO study (DOI 10.5281/zenodo.21842514).
