Abstract: Flexible films or sheets for forming high-breakdown strength, high-temperature capacitors are disclosed. Amorphous metal oxides and nitrides, preferably SiO2 or HfO2, with a dielectric constant (k) greater than 2 and stacks of oxides and nitrides formed over conducting substrates may be formed. The dielectrics may be formed by reactive sputter deposition of the amorphous materials onto cooled substrates. The cooled substrate allows the films to be amorphous or nanocrystalline and results in films that can be flexed and that can be rolled into cylindrical shapes. An important application for these dielectrics is in high energy-density wound capacitors.

Abstract: Commercially available coaxial cables have been used successfully in single shot electromagnetic launcher and other pulsed power applications. The use of a coaxial cable interface between power source and pulsed power load reduces external magnetic fields and also aids in standardizing the interface, enhancing inter-changeability between a variety of power supplies and loads. As pulsed power systems continue to become more energetic and as the importance of repetitive operation increases, the use of commercially available cables becomes impractical because of the large number required for appropriate energy transfer. The cable according to the invention overcomes many problems encountered in the use of conventional cables. It incorporates a large area, flexible conductor in both the current feed and current return path, and matches these conductor cross-sections to provide uniform current paths.

Abstract: The terminations provide a means for connecting coaxial power cables carrying tens to hundreds of kiloamperes of pulsed current to electrical devices without producing arcing or melting during operation; and also provide mechanical support at cable ends where otherwise unsupported ends would be damaged due to magnetic force acting on current carrying members. To avoid contact arcing (1) the contact supplies mechanical support to the cable at the termination, to prevent magnetic forces from moving the conductor in any direction which would loosen the contact; (2) the connector is installed with sufficient force to meet the a given resistance criterion, and the force is maintained during the expected life of the cable and termination; (3) a smooth, well-defined surface is provided at the surface of the connector where it interfaces with the mating system contact.

Abstract: A flowing gas source of vacuum ultraviolet line radiation system capable of perating efficiently at low pressures and low power levels. The system includes a source body assembly having nozzle member with an orifice on one end for sustaining an electrical discharge; a vacuum vessel for providing an evacuated region outside the orifice; a cooling jacket over a gas tubular element; and an insulator mounted upon the tubular element by vacuum coupling separating the source body electrically from the vacuum vessel. The vacuum ultraviolet radiation is derived from an electrical discharge sustained in a gaseous/vaporous media which flows through a differentially pumped orifice. The inherent differential pumping at the nozzle orifice results in a reduced gas load to instrumentation which may be operatively connected to the output port of the vacuum vessel.
