Abstract
A fusion reactor includes a fusion plasma reactor chamber. A magnetic coil structure is disposed inside of the fusion plasma reactor chamber, and a structural component is also disposed inside of the fusion plasma reactor chamber. The structural component couples the magnetic coil structure to the fusion plasma reactor chamber. A superconducting material is disposed at least partially within the structural component. A plurality of cooling channels are disposed at least partially within the structural component. An insulating material is disposed at least partially within the structural component.

1-17. (canceled)
A method for protecting an object configured to be at least partially immersed in a plasma, comprising:
- applying a magnetic field around a superconducting material;
- and
- cooling the superconducting material to a temperature sufficient to cause the superconducting material to exclude the magnetic field, wherein the superconducting material is disposed at least partially within the object.
