Abstract: Described is a cable comprising a plurality of high temperature superconductor (HTS) components, a plurality of electrically conductive segments extending along a length of the cable, each of the plurality of electrically conductive segments comprising one of the plurality of HTS components, and an electrically insulating material arranged between adjacent ones of the plurality of electrically conductive segments.

Abstract: Structures and methods enable emergency or rapid shutdown of an energized no-insulation (NI) superconducting magnet, without damage due to thermal effects of a quench. A resistive bypass wire is coupled between electrical terminals of the magnet coil, and does not pass significant current during normal magnet operation. When rapid shutdown is required, the bypass wire is cooled below its critical temperature, adding a superconducting current path in parallel with the magnet coil. A portion of the coil is then heated above its critical temperature, interrupting current flow through the coil. Hot spots near the coil leads are mitigated through the use of a conductive structure, such as copper cladding, that carries away excess heat due to the quench. This heat may be deposited in a resistive matrix, such as a steel plate, over a duration of seconds and without compromising other magnet design parameters.

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.

Abstract: A motive magnetic system includes a first coil configured to produce a constant magnetic field. The first coil includes a support structure having a groove and a high temperature superconductor (HTS) cable comprising a metal at least partially filling the HTS cable. The cable is disposed in the groove. A second coil is configured to produce an alternating magnetic field. The first coil and the second coil are positioned so that the constant magnetic field and the alternating magnetic field interact to cause a magnetic force between the first coil and the second coil that causes motion between the first and second coil.

Abstract: Ions are released over time from an ion source into a beam area proximate a central axis. A radiofrequency (RF) system with a variable frequency and variable voltage accelerates the ions in orbiting trajectories expanding outward from the central axis. The ions are accelerated to different extraction energy levels within a given design range at a shared extraction radius from the central axis. An RF-frequency versus ion-time-of-flight scenario is set such that the frequency versus time scenario is the same for any ion extraction energy from the given design range, and a constant-or-variable-RF-voltage versus ion-time-of-flight scenario is adjusted to provide ion acceleration from injection to extraction for ions with different respective extraction energy levels within the given design range; and the ions are extracted at the different energy levels at the shared extraction radius.

Abstract: A method of connecting prefabricated pieces of an HTS cable onsite is disclosed. This quick and reliable procedure of connecting pieces of HTS cable adds to the flexibility of designing and installing power transmission and distribution grids. The joint can also be dissembled such that it can be dismantled for replacing the cable on one side of the connection. The joint can then be reassembled with a new cable in its place. This facilitates repairing the electrical grid in case of local damage to the cable, as well as reconfiguring the grid in case this is required. The complexity of creating demountable HTS cable joints is due to the necessity to create and maintain continuity of several media across the joint along the length of the cable. Various combinations of design options satisfying these requirements are possible.

Abstract: Various SMES systems that include two magnets in a single cryostat are disclosed. These dual SMES systems can be used, for example, to provide uninterrupted power to a data center. The two coil sets are arranged such that they are magnetically decoupled from each other. In one embodiment, a toroidal coil set is used as the primary coil set. The toroidal coil set has a plurality of toroidal field (TF) coils extending radially outward and evenly spaced in the circumferential direction. The second coil set may be a solenoidal coil set having a main coil and a plurality of shielding coils. The toroidal coil set may be disposed in the space between the main coil and the shielding coils of the solenoidal coil set. Alternate designs are also presented.
