Description:

The present technology employs electrically insulating coatings on the superconducting wire. The novel technology employs semiconducting or resistive coatings in lieu of insulating coatings which allows smaller, more compact, and less expensive electromagnets and also allows the opportunity to eliminate expensive and complicated quench protection systems. Resistive coatings mitigate delays in reaching full field during ramping and minimize eddy current losses in the superconducting magnet during field changes in comparison to no-insulation coatings.

Advantages:

  • Enable faster ramping times compared to no-insulation coils
  • Resistive coatings mitigate delays in reaching full field during ramping and minimize eddy current losses during field changes
  • Enable a more compact superconducting magnet which allows higher magnetic fields by reducing the amount of superconducting material required to achieve a given magnetic field and by reducing the ancillary system requirements for cryostats and refrigeration
  • Enable the superconducting coil to be self-protected
