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: Schemes are described for joint geometry and placement in superconducting magnets. According to some aspects, a joint may be implemented in a modular component of a superconducting magnet, such as a plate that includes a spiral superconducting path, with the joints providing electrically conductive connections between the superconducting paths of adjacent plates. A joint may be installed and coupled to the component (e.g., plate) after its fabrication, thereby providing freedom in design of both the joint and the component. In at least some cases, the joints may be arranged to be flush with a surface of the component after installation into the component so that neighboring instances of the components may be stacked flush with one another, thereby putting joints from the neighboring components into intimate contact with one another.

Abstract: A pressure gradient CVI/CVD process includes providing a furnace defining an outer volume. Porous structures and ring-like spacers are assembled in a stack with a ring-like spacer between each adjacent pair of porous structures. The stack of porous structures is disposed between a bottom plate and a top plate in the furnace, wherein the bottom plate, the stack of porous structures, and the ring-like spacers define an enclosed cavity. A channel provides fluid communication between the enclosed cavity and the outer volume. A gas composition is introduced into the enclosed cavity. A portion of the gas composition flows through the channel. A pressure gradient is maintained between the enclosed cavity and the outer volume. The gas composition in the outer volume is provided at a pressure of at least about 15 torr. The porous structures are densified.
