  • Patent number: 11139097
    Abstract: A linear actuation assembly includes an electromagnetic coil configured to allow electric current to pass therethrough in either direction creating magnetic flux based on the electric current and its direction. The electromagnetic coil defines a center axis, an inner diameter, and first and second sides. A first set of magnets is disposed in end-to-end relation adjacent the first side of the electromagnetic coil at the inner diameter thereof. A second set of magnets is disposed in end-to-end relation adjacent the second side of the electromagnetic coil about the inner diameter thereof.

  • Patent number: 11094439
    Abstract: Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly—which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways—is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.
