Superconducting applications require numerous superconducting connections between devices operating at cryogenic temperatures. Conventional NbTi superconducting wires face challenges due to their bulk, complex assembly, and are susceptible to crosstalk and mechanical instability. There is a need for a conductor device that is space-efficient, reduces electromagnetic interference, and ensures reliable and reproducible connections in cryogenic environments.


A schematic of the novel conductor device (100) is shown in the below figures. The conductor device comprises multiple superconducting wires (10) encapsulated in a polymer material (20), forming a flat, self-supporting cable. The encapsulation material provides electrical insulation, maintains the relative positions of the wires and enhances mechanical stability. The conductor device is manufactured using an extrusion process, which simplifies production and allows for customization in wire number and length. The design includes flattened end sections (11) for easier connections and a shielding layer (31) to protect against electromagnetic interference, ensuring reliable performance in low-temperature conditions.
