Solderless, In-Parallel Coils of Superconducting Wire

Superconducting wire improves devices such as superconducting electromagnets by requiring power and space in high magnetic fields. Coils of superconducting wires can be used to make Helmholtz coil(s) which is an arrangement of coils with in-series connection and are designed to extend an electromagnetic field over a larger area in devices such as the MRI used for imaging the entire body. This technology specifically addresses the complications that arise when using a high temperature superconducting wire in a series of complicated windings such as the Helmholtz coil to extend the superconducting, electromagnetic field. Slitting the super conducting wire into two pieces from the middle of the wire so that two, separated halves of wire derive from one piece and remain connected at the ends and allow the design of Helmholtz coil to be made from just one continuous super conducting wire. Any sever between two or more super conducting wires would require a joint to electrically connect the wires which inherently will have less conductivity than the superconducting wire. Less conductivity at this joint fouls and disables the ability of the connected superconductors from reaching true persistent current operation.

Applications

  • MRI may be the largest commercial market, especially when helium consumption is prohibitively expensive or difficult
  • ‘Battlefield MRI’ - DoD application
  • Magnets for motors, generators (e.g., wind turbines), energy storage (SMES)
  • At low temperatures, HTS have very high upper critical fields – useful for fusion, colliders, & high-field NMR/MR

Problem Addressed

  • Adding electrical joints such as solder or weld to connect super conducting wires inherently adds resistance to a circuit of superconducting wires or a series of wires wrapped in coils such as Helmholtz coils.
  • High temperature superconducting wire does not require liquid helium for operation

Competitive Advantages

  • Customized equipment gives patients more effective therapy
  • Customized equipment “fits better” and therefore can cause the user to feel better/more confident while coping with this condition
  • Reducing the disability factor of paralysis patients reduces extra burden placed on society
