ABSTRACT:
A multibeam electron gun comprises two spaced successive electrodes individually held in position from a common electrically-insulating support. One electrode comprises a single metal plate having at least three electron-beam defining first apertures therein. The other electrode is a composite structure comprising a support plate and a second metal plate having at least three electron-beam-defining second apertures therein. Each of the first and second plates includes substantially triangularly-shaped alignment apertures which are mutually aligned so that the beam-defining apertures are aligned along common axes.
