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.

Grooved, stacked-plate superconducting magnets and electrically conductive terminal blocks and related construction techniques

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.

Demountable solder joints for coupling superconducting current paths

Techniques described herein relate to systems and methods for obtaining a high temperature superconducting (HTS) cable assembly and filling the HTS cable assembly with a molten metal, such as solder.
