Zusammenfassung: | A directly heated thermionic flat emitter has an emission surface divided by slots into interconnects that have respective terminal lugs forming power leads arranged at a peripheral edge. A number of segments are connected by respective narrow webs to the outermost interconnects of the emitter but have no connection to one another. The webs are arranged and dimensioned such that practically no current can flow from the interconnects to the segments and so that thermal conduction to the segments is largely suppressed. |
