Title (EN) MULTI-GRID ELECTRON GUN WITH SINGLE GRID SUPPLY
(FR) CANON À ÉLECTRONS À GRILLE MULTIPLE À ALIMENTATION À GRILLE UNIQUE
Abstract:
(EN) Some embodiments include a system, comprising: a high voltage enclosure; a cathode disposed in the high voltage enclosure; an anode disposed in the high voltage enclosure; a plurality of grids disposed in the high voltage enclosure between the cathode and the anode; a voltage source configured to generate a common grid voltage; and a voltage divider disposed in the high voltage enclosure, configured to generate a plurality of grid voltages based on the common grid voltage, and configured to apply at least two of the grid voltages to the grids.
(FR) Certains modes de réalisation comprennent un système, comprenant : une enceinte à haute tension ; une cathode disposée dans l'enceinte à haute tension ; une anode disposée dans l'enceinte à haute tension ; une pluralité de grilles disposées dans l'enceinte à haute tension entre la cathode et l'anode ; une source de tension configurée pour générer une tension de grille commune ; et un diviseur de tension disposé dans l'enceinte haute tension, configuré pour générer une pluralité de tensions de grille sur la base de la tension de grille commune, et configuré pour appliquer au moins deux des tensions de grille aux grilles.
