Stellarator Toroidal Field Magnet Structure.

A possible way to manufacture the complicated bent and twisted shape while holding the superconducting tapes in place and with low stress.

Structure to hold tapes (Teflon)

Stainless Steel Casing

Wendelstein 7-X made in Germany, for example.

Stellarator TF Magnet Doc

Japanese LHD

Modified with a twisty shape to minimize stress on HTS ribbons.
