ABSTRACT:
Flat and slightly convex pyrolytic graphite grid electrodes are very suitable for use in electric discharge tubes, are example in ion sources, cathode-ray tubes, travelling waveguides and transmitter tubes. It has proved possible to manufacture such electrodes by manufacturing the grid and the grid holder of the pyrolytic graphite electrode from one piece of pyrolytic graphite. Such integral grid electrodes have very good mechanical and thermal properties.
