Abstract
Abstract An improved cathode for a sputtering system includes a metal cylinder and strips of material bonded to the inside of the metal cylinder and/or material sprayed onto the inside of the metal cylinder. The strips may have various specified compositions and/or configurations and/or other characteristics which enhance the ability of the sputtering system to deposit films of high temperature superconductor material on substrates.
