A type of such an ‘intelligent superconductor tape’ requires incorporation of specific thin films in the superconductor architecture. The PLD tool will enable fabrication of those films,” said Selvamanickam. Thin films are very thin layers of material that scientists can deposit or apply onto surfaces to achieve unique properties not seen in a bulk form of the material. They offer a wide range of benefits and are utilized in various industries, including electronics, energy, optics, sensing and others. Although magnet quenches are fairly routine, in 2008 at CERN’s Large Hadron Collider, a magnet quench caused damage to more than 50 superconducting magnets. The PLD will also be used in other projects led by Selvamanickam and other faculty and underwritten by the U.S. Navy, including improving energy storage and propulsion systems, enhancing high-performance of solid-state, flexible batteries and reducing fuel consumption and surface corrosion of ships.
