    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. 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.

The photomultiplier comprises a housing whose inside is maintained vacuum, and, in the housing, a photocathode, an electron-multiplier section, and anodes are disposed. The electron-multiplier section has groove portions for cascade-multiplying photoelectrons as electron-multiplier channels, and the anodes are constituted by channel electrodes corresponding to the groove portions respectively defined by wall parts. In particular, at least parts of the respective channel electrodes are located in spaces sandwiched between pairs of wall parts defining the corresponding groove portions.

    摘要: A photomultiplier tube, a photomultiplier tube unit, and a performance-improved radiation detector for increasing a fixing area of a side tube in a faceplate while increasing an effective sensitive area of the faceplate. In the photomultiplier tube, a side face (3c) of the faceplate (3) protrudes outward from an outer side wall (2b) of a metal side tube (2), so that a light receiving area for receiving light passing through a light receiving face (3d) of the faceplate (3) is increased. The overhanging structure of the faceplate (3) is conceived based on a glass refractive index. The overhanging structure is aimed to receive light as much as possible which has not been received before. When the metal side tube (2) is fused to the glass faceplate (3), a fusing method is adopted due to joint between glass and metal. Joint operation between the faceplate (3) and the side tube (2) is reliably ensured. Accordingly, the overhanging structure of the faceplate (3) is effective.

    摘要: A metal side tube (2), a glass faceplate (3), and a stem plate (4) constitute a hermetically sealed vessel (5) for a photomultiplier tube. An edge portion (20) is provided at on open end (A) of the side tube (2). The edge portion (2) is embedded in the faceplate (3) in such a manner as to strike on the faceplate (3). Accordingly, high hermeticity at a joint between the side tube (2) and the faceplate (3) is ensured. The edge portion (20) extends upright in an axial direction of the side tube (2), so that the edge portion (20) can be embedded as close to a side face (3c) of the faceplate (3) as possible. This structure increases an effective sensitive area of the faceplate (3) to nearly 100%, and decreases dead area as close to 0 as possible. As described above, the photomultiplier tube (1) according to the present invention has enlarged effective sensitive area of the side tube (3) and enhanced hermeticity of the joint between the faceplate (3) and the side tube (2).
