Abstract: Described are concepts directed toward systems, structures and techniques to create low-resistance, high current capacity, demountable solder joint connections. Such systems, structures and techniques may be used to simultaneously create low-resistance, high current capacity, demountable solder joint connections at multiple locations between no insulation (NI) superconductors and in particular between NI high temperature superconductors (HTS) such as may be used in NI-HTS magnets.

Abstract: Systems, methods, and devices to facilitate insertion of certain leads with electrode(s) into patients are described. Leads can be implanted to work in conjunction with a cardiac pacemaker or cardiac defibrillator. A lead for cardiac therapy may be inserted into an intercostal space associated with the cardiac notch of a patient. Devices for delivery may include, for example, a delivery system coupled with an electrical lead and having a handle, a component advancer and insertion tips. The handle is configured to be actuated by an operator and the component advancer is configured to advance an electrical lead into the patient. The insertion tips can be configured to close around the electrical lead within the component advancer, to push through biological tissue, and to open to enable the lead to advance into the patient. The electrical lead can also be maintained in a particular orientation during the advancement into the patient.

Abstract: A high capacity current lead (10) comprises components that are electrically coupled using indium joints. The current lead includes a heat exchanger having a portion at room temperature (100) and a portion (200) within a vacuum cryostat. The room-temperature portion is temperature controlled against both overheating and over-cooling. The cryogenic portion (200) of the heat exchanger is electrically coupled to a coolant boiling chamber (300) using indium joints. The boiling chamber (300) has a lid and a base that may be electrically coupled using indium joints, or they may be brazed. The boiling chamber (300) is surrounded by a vacuum lid that may be electrically coupled to the base using indium joints, or brazed. The base is electrically coupled to a superconductor module (400) having high-temperature superconductor (HTS) tapes for conveying current to a device, such as a superconducting electromagnet.

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: Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

Abstract: 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.

Abstract: A rapid quenching line can be suitable for use with hot coil at, or above the metal strip's recrystallization point. Hot coil can be uncoiled by a low tension uncoiler using a non-contacting hold-down device. The metal strip coming off the hot coil is rapidly quenched (e.g., at rates of at or above 100° C./s or 200° C./s) through multiple quenching zones. Coolant can be removed, such as with an air knife and/or a wiper (e.g., an ultra-compliant wiper). Steam can be collected from earlier quenching zones and be repurposed to provide humid air to the metal strip, such as at regions where the temperature of the metal strip is at or below the Leidenfrost point. The cooled metal strip can pass through a bridle to increase the tension in the metal strip before the metal strip is optionally lubricated and then recoiled or otherwise further processed.
