Update. They tested it and it works.

Fascinating.

For Polywell applications, would this be a method of avoiding the cusps created by the close approach of the rings?* In effect, make each ring-generated magnetic field ignore the presence of the others? Confinement advantages? Structural advantages?

Maybe not, we want current carrying superconductors to create magnetic fields outside the ring casings. Would the ferromagnetic part of the shield attract the magnetic field generated by the internal superconductors?

*I forget which name is applied to those cusps.

For Polywell, I see it possibly useful for test probes and/or support structures that don't affect the "ideal" B field.
