This disclosure relates to an apparatus or device commonly referred to as a superconducting resonant cavity or Radio Frequency (SRF) cavity, the related components associated with the SRF Cavity, and various fabrication methods thereof. SRF cavities are used to accelerate charged particles to high energies and high velocities and various fabrication methods of said SRF apparatus. SRF cavities are used in a wide variety of applications ranging from particle accelerators, to light sources for spectroscopy, to linear accelerators for the transmutation of nuclear waste and the advanced production of tritium, to NMR and MRI imaging and spectroscopy, and proton radiation therapy for the treatment of certain types of cancer. This disclosure further describes a wide variety of means and methods for: a) the fabrication of SRF cavity structures, b) at least one or more film deposition means, and c) at least one or more heat treating means using either the Bronze Route or Internal Tin processes to form the superconducting NbSn phase on the interior surface of an SRF cavity via a solid state diffusion reaction process.

An intelligent current lead device, its design, fabrication, and methods of operation are described in this disclosure. The intelligent current lead device described in this disclosure electrically and thermally connects and disconnects one or more power sources or loads operating at one temperature reservoir with one or more machines or devices operating at either the same or a different temperature reservoir. The intelligent current lead can operate in either an active mode or passive mode. The intelligent current lead device may incorporate the use of multiple types of diagnostic sensors and instrumentation, which can be monitored, interpreted, and analyzed. The program logic of the intelligent current lead may be used to interpret the data obtained from the diagnostic sensors and instrumentation in order to adjust/actuate/switch the current lead so as to optimize its configuration to respond to requirements of an electrical load that changes with time. There are many applications that the intelligent current lead can be used in conjunction with including but not limited to: superconducting magnets, transformers, power cables, energy storage, motors, generators, fault current limiters, circuit breakers, fusion magnets, accelerator magnets, MRI magnets, NMR magnets, induction heaters, magnetic separators, among other applications.

This invention uses a novel approach for the fabrication of low temperature superconducting (LTS) magnesium di-boride (MgB) wire or cable. This approach employs the use of a 'high temperature fiber or tape' as a high performance substrate material. High temperature fiber substrates are low-cost, round, light-weight, non-magnetic, and capable of withstanding, without degradation, the high reaction temperatures necessary to form the superconducting phase of Mg&#x2014;B.

This patent application relates to the use of thin high temperature fibers, specifically optical fibers, for use as a substrate material in the fabrication of long-length low temperature superconducting and high temperature superconducting wire. The superconducting material is deposited on the fiber using either a thin or thick film deposition technique. The fiber can have a dual use in the transmission of data using either traditional optical means or the transmission of electrical current via the deposited superconductor. A buffer layer or layers is used between the high temperature fiber and the superconductor to promote grain alignment and enhance the current carrying capacity of the wire.

Smooth, patterned substrates useful in producing decorative cookware are formed by coating a base with a mixture of fluoropolymer and magnetic flakes and magnetically inducing an image in the polymer coating composition. The baked fluoropolymer release coating contains magnetizable flakes, a portion of the flakes being oriented in the plane of the substrate and a portion of said flakes being magnetically reoriented to form a pattern in the coating which is observed in reflected light, the flakes having a longest dimension which is greater than the thickness of said coating. The patterned substrate is formed by applying magnetic force through the edges of a magnetizable die positioned under a coated base to induce an imaging effect or pattern. The coating composition is then cured resulting in a smooth surface, patterned nonstick finish on the substrate.
