  • Device for generating cold plasma in a vacuum chamber and use of said device for thermo-chemical processing
    Patent number: 9011655
    Abstract: A device for generating a cold plasma in a vacuum enclosure includes a cathode body having hollow chambers for confining the plasma. Magnets are placed around each hollow chamber for creating a magnetic field forcing electrons to rotate about the field lines. The cathode body cooperates with an element for circulating a coolant to extract the heat generated by an intense ion bombardment at each of the hollow chambers.
    Type: Grant
    Filed: February 1, 2008
    Date of Patent: April 21, 2015
    Assignee: H.E.F.
    Inventors: Philippe Maurin-Perrier, Hervé Chavanne, Laure Poigt
