Techniques are described for a wind power generator in which a refrigerant such as liquid helium and/or helium gas is applied to superconducting magnets via thermally conductive flexible structures. These structures thermally couple the refrigerant channels to the magnets, and/or to a thermally conductive structure (e.g., metal plate) to which the magnets are thermally coupled. The thermally conductive flexible structures may be arranged so that motion of the magnets relative to the cryogenic channels that cool the structures during heating and/or cooling of the magnets does not result in damage to the thermal connection between the channels and the magnets. The stationary stage of the generator may house a cooling station, and transfer the refrigerant to the rotary stage via a suitable rotary union.

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.

TECHNIQUES FOR QUENCH DETECTION IN SUPERCONDUCTING MAGNETS
Techniques for early detection of a local normal zone in superconducting magnets are provided. A superconducting magnet may include an insulated superconductor that is arranged along the primary non-insulated winding of the magnet. If a portion of the primary winding heats up, this may cause the insulated superconductor co-winding to also heat up. A quench may be detected by connecting ends of the co-winding to a voltage meter because heating of the co-winding may produce a measurable change in its resistance.
Quench detection apparatuses and methods for high-temperature-superconducting (HTS) cables are described. Electrical signals are transmitted along a metallic coolant-carrying waveguide of the HTS cable. The transmitted signals are detected and the transmission and/or absorption properties of the coolant-carrying cable determined. Changes in the properties indicative of heating of the HTS cable associated with quench are detected.

Techniques are providing for mitigating overcurrents in superconducting magnets by adding a closed loop of superconductor to the magnet that acts as an electromagnetic shield. A time-varying external magnetic field may induce a current in the closed loop, thereby generating a magnetic field that opposes the external magnetic field, and reducing the amount of current induced by the external magnetic field in the primary current-carrying superconductor of the magnet. As a result, the effect of overcurrents can be reduced or removed.
Described is an insulative layer for use in systems utilizing a high temperature superconductor (HTS). The insulative layer comprises a first layer of an insulative material, a second layer of an insulative material and a third layer of an electrically conductive material disposed the first and second layers. The electrically insulating material of the first layer and the electrically insulating material of the second layer are both resistant to grinding forces. The third layer is provided from a material having a resistance to oxidative degradation, weather, and radiation, as well as resistance to abrasive and fictional wear at cryogenic temperatures. In one application, the insulative layer may be disposed at an interface between a toroidal field (TF) coil and a central solenoid (CS) of a high temperature superconducting magnet.
Techniques are described for improving quench damage resiliency in non-insulated (NI) high temperature superconductor (HTS) magnets. The techniques may include tuning an amount of HTS tape within turns of a winding of an NI-HTS magnet to reduce variation in critical current across the winding, and/or may include adjusting the turn-to-turn resistance of the windings by adjusting turn-to-turn spacing between windings and thereby reduce variations in joule heating between turns during a quench.
Techniques are described that allow for HTS cables to be solder-filled more easily, quickly, and with a reduced degradation to the performance of the HTS in the cable. In particular, a channel within an HTS cable may include a primary channel into which the HTS is arranged, in addition to a secondary channel that provides an increased hydraulic cross-section through which the solder can flow. The secondary channel may be connected to the primary channel (e.g., as a side-channel). If the secondary channel has an opening within the primary channel that is smaller than the HTS material being placed in the primary channel, the HTS material is not at risk of moving into the secondary channel, which can provide a space proximate to the HTS material and the primary channel through which the solder can freely flow.

When the current to be measured is a plasma current in a tokamak, the current sensor may be placed behind shielding tiles on the inner wall of a vacuum vessel that contains the plasma. Another current sensor may be placed on an external wall of the vacuum vessel, and the outputs subtracted to measure a current flowing through only the vessel itself.

Techniques are described for lowering strains applied to superconducting material in a superconducting magnet by arranging structural partitions between turns of the superconducting material that intercept and transfer strain to a mechanically stronger structure, such as the housing of the magnet. A structural partition may be formed with a feedthrough slit so that the superconducting aterial can easily pass through the partition. A number of structural partitions may be interspersed between groups of turns of super-conducting material in a magnet so that forces can be sufficiently distributed by the partitions throughout the magnet. At the same time, the number of structural partitions may be selected to minimize the amount of space within the magnet occupied by the partitions that could otherwise be occupied by current-carrying superconducting material.

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.
Techniques are described for a wind power generator in which a refrigerant such as liquid helium and/or helium gas is applied to superconducting magnets via thermally conductive flexible structures. These structures thermally couple the refrigerant channels to the magnets, and/or to a thermally conductive structure (e.g., metal plate) to which the magnets are thermally coupled. The thermally conductive flexible structures may be arranged so that motion of the magnets relative to the cryogenic channels that cool the structures during heating and/or cooling of the magnets does not result in damage to the thermal connection between the channels and the magnets. The stationary stage of the generator may house a cooling station, and transfer the refrigerant to the rotary stage via a suitable rotary union.

TRITIUM INJECTION TECHNIQUES AND RELATED SYSTEMS AND METHODS
Techniques are described for delivering a metered flow of tritium gas to a fusion power system at a constant (or substantially constant) flow without feedback control being necessary, and while allowing all (or almost all) of the tritium in a reservoir to be delivered to the system. A constant pressure (isobaric) tritium injection system is described comprising a process chamber, at least part of which is flexible, and a regulating chamber arranged adjacent to the process chamber. Tritium in the process chamber may be pushed out of the injection system by managing the pressure of a regulating gas in the regulating chamber. As the pressure of the regulating gas increases, this causes the process chamber to be compressed due to the flexible portion(s) of the process chamber, thereby increasing the pressure of the tritium gas.
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.

Techniques are described for forming a defect-tolerant superconducting magnet. The techniques may be based on current sharing processes within a stack of high temperature superconductor (HTS) tapes in operation. Application of these techniques may allow HTS tapes containing defects to be utilized to produce a magnet that has a lower critical current than a comparative magnet that contained only defect-free HTS tapes, but with increased flexibility in the design and fabrication of the magnet. In addition, because the magnet may comprise HTS tapes that include defects, the cost of the magnet may be substantially lower than a comparative magnet that comprises only defect-free HTS tape.

FIELD QUALITY CORRECTION IN NO-INSULATION SUPERCONDUCTING MAGNETS BY ADJUSTABLE CURRENT BYPASSES
A magnet system and method of operating may be used in connection with operating a superconducting electromagnet, for example in a tokamak. The magnet system includes a coil having windings retained within a non-insulated structure, so that current can pass both along the windings to generate a magnetic field, and between the windings. The amount of current passing through the coil is trimmed using a bypass circuit, coupled in parallel to the coil terminals. The bypass circuit is controlled on the basis of measurements of the field components to divert current from passing through the field coil. In this way, the magnetic fields of each of multiple field coils can be brought into mutual uniformity.
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.

Structures and methods enable emergency or rapid shutdown of an energized no-insulation (Nl) 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.

Schemes are described for conductor and coolant placement in stacked-plate superconducting magnets, including arranging coolant channels and conducting channels within the plates on opposing faces. If the two types of channels are aligned with one another across the plate stacks, the plates may be stacked such that the cooling channel in one plate is adjacent to the conducting channel of the neighboring plate. By stacking a number of these plates, therefore, cooling may be supplied to each conducting channel through the cooling channels of each neighboring plate. Moreover, by aligning the two types of channels, the stacks of plates may have improved mechanical strength because mechanical load paths through the entire stack that do not pass through any of the channels may be created. This arrangement of channels may produce a very strong stack of plates that can withstand high Lorentz loads.
