Abstract
Apparatus for depositing and tailoring anisotropic properties of ceramic oxide-superconductor films onto the outer surface of fibers, wires, rods, and bars and onto the inner surface of tubes, as well as onto the surface of disc-shaped substrates, employs first and second vacuum chambers, a cylindrical magnetron structure positioned within the first vacuum chamber, a disc-shaped cold cathode positioned within the first vacuum chamber for providing a beam of energetic electrons for injection into a plasma region of the cylindrical magnetron structure, and a ring-shaped cold cathode positioned within the second vacuum chamber for providing a disc-shaped beam of electrons impinging upon the deposited film for annealing it. The magnetron cathodes comprise either single metal elements or mixtures thereof. A planar magnetron and a line-shaped cold cathode that produces an electron beam impinging on the surface of a planar substrate to provide a uniform strip heat zone are employed for depositing superconducting thin films of metal oxide ceramic materials onto the surface of wide area planar substrates.
