ELECTRON MULTIPLIER TUBE HAVING ELLIPSOID-SHAPED ELECTRODE SURFACES

摘要

An electron discharge device with a series of electrodes, one or more having an interior ellipsoid-shaped cavity wall surface, a portion of which is formed of, or coated with, electron emissive material. Electron communication from or to a preceding or succeeding electrode, respectively, is provided through an input aperture and an output aperture, respectively, in each of the interior ellipsoid-shaped cavity wall surfaces. Various means of accelerating electrons, emitted from each ellipsoid shaped cavity wall surface, through the output aperture thereon, to the succeeding electrode are provided.
