Abstract

PURPOSE:To eliminate the generation of deformation in a hole part of an electrode further maintain stable quality of focusing. CONSTITUTION:Two intermediate cups 14 having an electrode provided with burrings 14a are provided between a G3 electrode cup 12 and G3 electrode bottom 13. This burring 14a is utilized, and deflection of the electrode is suppressed further prescribed work can be ended without contacting the electrode to a hole part of the cup 12. Accordingly, the work can be performed without causing the deformation of a bridge 12a in the hole part of the cup 12 to obtain a stable focus characteristic.

あった。In the conventional electron gun assembly method, there are several manufacturing steps using the beam passage as a guide, but especially the span setting step in which the cathode (l!: G) and electrode are set and fixed at a certain distance. In the conventional electron gun as shown in FIG. 1, the pin 1 of the span set can only be guided by the hole in the G3 electrode cup 12 and the hole in the G3 electrode bottom 13. Therefore, the bridge of the hole The deformation of 2a is unavoidable and has the disadvantage of deteriorating focus characteristics.
