X-ray image intensifier with electron optics coating |
摘要 |
An x-ray image intensifier has an electrode system for focusing electrons, produced by the incidence of x-radiation on the input luminescent screen, onto the output luminescent screen. An electrode of the electrode system is applied as a coating to the interior of a one-piece electrode substrate, which forms the envelope of the vacuum vessel of the x-ray image intensifier, and a voltage is applied to the coating so that the potential field continuously increases in the space between the input luminescent screen and the output luminescent screen.
