Abstract
A method of manufacturing an electron gun component, in which the electrodes are positioned in a jig by means of positioning means which are located at the edge of the electrodes. The method does not use pins to position the electrodes. In an exemplary embodiment, the electrodes are stacked in the jig with clearance. The positioning means are located at the vertices of a polygon which comprise the apertures in the electrodes. If an electrode is tubular in shape, the positioning means and the apertures in the electrode are preferably located in one plane.
