<p>In one embodiment, an electron emission cathode and a method for its manufacture comprise an electrically conductive flat structure (1) defining an emission surface, into which a slot pattern (7a, 7b) is incorporated, preferably by electro-erosion or laser cutting, such that a current conductor (I), defined by the slots of the slot pattern, is formed between two terminals (9a, 9b) in order to conduct a heating current, the width of the slots and the material thickness of the flat element in significant areas of the same being less than the width (D) of the current conductor (I). <IMAGE></p> |
