THERMIONIC FLAT ELECTRON EMITTER |
摘要 |
A thermionic flat electron emitter has an emitter arrangement with an emitter plate having slits therein that produce serpentine current paths. The emitter arrangement has a structure that, in operation, causes the electron density of the emitted electrons to be lower in the central region of the emitter plate than in a region adjoining the central region.
