    Abstract: A smart susceptor assembly including an electromagnetic flux source such as one or more inductors, a geometrically complex-shaped susceptor having one or more contours, and a cladding on or over the susceptor. The cladding can alter both the thermal performance and the electrical operation of the smart susceptor assembly. With regard to thermal performance, the cladding can function as a passive heat exchanger to dissipate thermal energy across the surface of the susceptor. With regard to electrical operation, the cladding can provide a current path after portions of the susceptor heat and become low or non-magnetic.

  • Patent number: 10084366
    Abstract: An apparatus and method for charging a superconductor, such as a high temperature superconductor (HTS), in-situ, including a superconductor that is magnetized by a magnet. A surface area of the magnet is smaller than a surface area of the superconductor and the magnet scans the surface area of the superconductor to magnetize the superconductor one portion at a time. An additional compression superconductor may be used to compress the magnetic flux from the magnet such that the magnetic flux exits the compression superconductor via an aperture on the surface of the compression superconductor and then impinges the surface of the superconductor being charged. The superconductor is assembled in a machine prior to being magnetized and may be cooled prior to magnetization.
