  • Channel spark source for generating a stable focused electron beam
    Patent number: 7183564
    Abstract: In a channel spark source triggered by gas discharge for generating a stable focused electron beam, a gas supply for a hollow cathode thereof is provided which generates in the hollow cathode a pressure differential so that the multiplication of charge carriers in a trigger plasma of a trigger plasma source connected to the hollow cathode provides for a reliable gas discharge and the formation of a stable electron beam which exits the arrangement and which does not damage the internal passages of the arrangement.
    Type: Grant
    Filed: August 11, 2004
    Date of Patent: February 27, 2007
    Assignee: Forschungszentrum Karlsruhe GmbH
