Multifilamentary superconducting cable and a method of manufacturing it

摘要

A Nb-Ti or Nb-Zr low temperature superconducting (LTS) wire is coat with molten AgN03 which is then decomposed to form a uniform silver metal (Ag) coating on the LTS wire. A uniform coating of molten Al or Al alloy is formed on the Ag coated LTS wire and then solidified. A bundle of the coated LTS wires is inserted into an Al or Al alloy tube and cold worked to form a multifilamentary LTS cable comprising the Ag coated LTS wires each surrounded by an Al or Al alloy matrix.
