ABSTRACT:
A multibeam electron gun comprises two spaced successive electrodes individually held in position from a common electrically-insulating support. Each of the electrodes has at least three beam-defining apertures therein. Each of the electrodes also has two dissimilarly shaped alignment apertures therein which are mutually aligned so that the beam defining apertures are accurately aligned along common axes in a statically determined manner.
