  • Ion accelerator arrangement
    Patent number: 7247992
    Abstract: For an ion accelerator system having a special magnetic field structure with an alternating predominantly longitudinal and crosswise progression of the magnetic field, a geometry of the ionization chamber having a non-cylindrical shape of the chamber wall that is adapted to the progression of the magnetic field is proposed.
    Type: Grant
    Filed: December 13, 2003
    Date of Patent: July 24, 2007
    Assignee: Thales Electron Devices GmbH
    Inventors: Günter Kornfeld, Gregory Coustou, Norbert Koch
  • Ion accelerator arrangement
    Patent number: 7247993
    Abstract: The invention relates to an ion accelerator arrangement which uses a combination of a magnetic field having a cusp structure and a cross-section of an ionisation chamber that is extended in one direction transversally in relation to the longitudinal axis. This enables the ionic current to be advantageously scaled.
    Type: Grant

  • Plasma-accelerator configuration
    Patent number: 7084572
    Abstract: The invention relates to various advantageous embodiments of a plasma-accelerator configuration, especially for the configuration and design of electron sources used for ionizing the working gas and/or neutralizing the discharged plasma jet.
    Type: Grant
    Filed: June 24, 2002
    Date of Patent: August 1, 2006
    Assignee: Thales Electron Devices GmbH
    Inventors: Günter Kornfeld, Werner Schwertfeger, Roland Lenz, Gregory Coustou
  • Plasma accelerator system
    Patent number: 7075095
    Abstract: A multistage plasma accelerator system includes at least one intermediate electrode between the plasma chamber between electrodes that include each other. An especially good efficiency can be achieved by way of an uneven distribution of potential to the potential stages formed by the plurality of electrodes having a high potential gradient of the last stage, when the plasma beam emerges, and by a special shape of the magnetic field prevailing in the plasma chamber of the last stage.
