X-RAY TUBE EMITTER
Last updated:
Abstract:
An emitter for a closed x-ray tube includes an emitter body formed of a low work function emitter material, the emitter body having a major surface and a secondary surface. The major surface is adapted for emission of electrons from the low work function material. The emitter assembly is adapted to reduce an emission current density emitted from the secondary surface of the emitter body, as compared to the major surface.
