Abstract
The disclosed embodiments include embodiments such as an X-ray tube cathode filament system. The X-ray tube cathode filament system includes a substrate and a coating disposed on the substrate. In this cathode filament system, an electron beam is emitted from the coating but not from the substrate. The electron beam is produced through the use of the thermionic effect.
