ABSTRACT:
A vacuum vessel is configured by hermetically joining a faceplate to one end of a side tube and a stem to the other end via a tubular member. A photocathode, a focusing electrode, dynodes, a drawing electrode, and anodes are arranged within the vacuum vessel. The dynodes and the anodes have a plurality of channels in association with each other. The drawing electrode is placed on electrically-conductive supporting pins penetrating the stem. The dynodes are stacked with insulating members interposed between one another. Since the supporting pins and the insulating members are arranged coaxially, each electrode can be fixed by applying pressure in z-axis direction. At the same time, emission of light between the anodes and the drawing electrode can be suppressed, thereby enabling noise to be reduced.
