を変更することで対応していた。By the way, the G 2 assembly is a part for determining the divergence angle of the electron beam or the minor axis and major axis of the electron beam. Then, in response to various requests from users as final products, the size of the opening of the slot was changed each time.

ビームの液状に効き６現実的ではなかった。In order to make the electron beam horizontally long, the slot may be horizontally long. However, when changing the shape of the electron beam by using the one-stage slot, it is necessary to bring the slot opening size closer to the electron beam passage hole diameter of the G 2 electrode, depending on the desired characteristics.
In this case, extremely high accuracy is required when the G 2 electrode and the slot are combined, and the error during assembly is large, and it is not effective for the liquid state of the electron beam.

限界があるという欠点があった。By the way, since the slot to be assembled with the G 2 electrode of the conventional triode section is composed of a single plate, when the characteristics required by the customer are varied, There was a drawback that it was necessary to prepare various kinds of parts with different horizontal and vertical aperture dimensions. In addition, with the configuration with only one slot, the above-mentioned characteristics required by the customer, specifically, the change in the thickness of the electron beam from low current to high current, the setting of the focus voltage, the electron beam thickness, etc. There was a drawback that there was a limit to the control of the characteristics to satisfy it sufficiently.

The effective plate thickness of the slot can be increased by stacking it with the slot 3 which serves as a spacer having a large opening portion between the slot 3 and the slot 2. Further, at this time, since the opening of the first slot 3 serving as a spacer is large, the accuracy control during the assembling may be performed substantially only between the G 2 electrode 1 and the second slot 2. Thus, there is an advantage that the divergence angle of the electron beam can be finely controlled by changing the effective plate thickness of the slot.
