Photomultiplier tube having a metal-made sidewall |
摘要 |
A photomultiplier tube which obtains a large decrease in manufacture time, prevents generation of gas within the envelope, prevents deterioration of electron multiplier assembly (dynodes), and greatly reduces noise. The envelope includes an all-metal cylindrical sidewall, at one end of which is an annular, flange-shaped, metal sealing area. The stem of the photomultiplier tube has another annular flange-shaped, metal sealing area. These two sealing areas are welded together. Also a metal exhaust tube is connected to the stem by resistance welding. The metal exhaust tube is severed using pinch-off seal at the final stage of the photomultiplier tube production.
