Grooved, Stacked-Plate Superconducting Magnets And Electrically Conductive Terminal Blocks and Related Construction Techniques

An apparatus, comprising:

• an electrically conductive plate having a groove;
• a high-temperature superconductor (HTS) tape stack disposed in the groove, the HTS tape stack having a spiral shape;
• and
• a conductive terminal block electrically coupled to the HTS tape stack.

A stacked-plate magnet assembly, comprising:

• a first electrically conductive plate having provided therein at least one groove having a spiral shape;
• a second electrically conductive plate disposed over said first plate, said second plate having provided at least a groove having a spiral shape such that when a first surface of the first plate is disposed over a first surface of the second plate, said grooves form a spiral channel having an opening at a first end thereof on the first plate, a helical shaped path to the second plate, and an out-going path on the second electrically conductive plate;
• an electrically insulating material disposed between the first and second plates;
• and
• a non-insulated (NI) high temperature superconductor (HTS) tape stack having a length such that said NI HTS tape stack may be disposed in the channel formed by the grooves of said first and second electrically conductive plates such that said NI HTS tape stack forms a continuous path from a first outer-most surface of the first electrically conductive plate to a second outer-most surface of the second electrically conductive plate wherein said HTS tape is configured in said channel such that in response to generated forces, said HTS tape stack distributes forces into said first and second electrically conductive plates,
• wherein said NI HTS tape stack comprises one or more HTS tapes and wherein the number, size and type of HTS tapes in said NI HTS tape stack varies along a length of said NI HTS tape stack.
