摘要
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. Each electrode has cutout portions that overlap in a stacking direction, and supporting pins and lead pins are arranged in the cutout portions. A bridge is provided in a concave section arranged between unit anodes, and the bridge is cut off after the anode plate is placed on stem pins. Effective areas of each electrode and the anode are secured sufficiently, thereby allowing electrons to be detected efficiently.
