    • The present invention relates to a photomultiplier having a fine configuration capable of realizing stable detection accuracy. The photomultiplier has a housing whose inside is maintained vacuum, and a photocathode, an electron-multiplier section, and an anode are disposed in the housing. In particular, one or more control electrodes disposed in an internal space of the housing which surrounds the electron-multiplier section and the anode are electrically connected via one or more connection parts extending from an electron emission terminal of the electron-multiplier section. In this configuration, due to a voltage, instead of the applying between an electron entrance terminal and the electron emission terminal of the electron-multiplier section, being applied between the electron entrance terminal and the control electrodes, an electric potential gradient which is increased gradually from the photocathode side toward the anode side is formed in the electron-multiplier section, and a sufficient electric potential difference is provided between the electron emission terminal of the electron-multiplier section and the anode, which makes it possible to obtain stable detection accuracy.
    • 本发明涉及具有能够实现稳定的检测精度的精细结构的光电倍增管。 光电倍增管具有内部保持真空的壳体,并且光电阴极,电子倍增器部分和阳极设置在壳体中。 特别地,设置在外壳的内部空间中的一个或多个控制电极,其围绕电子倍增器部分和阳极通过从电子倍增器部分的电子发射端延伸的一个或多个连接部分电连接。 在该结构中,由于电压而不是在电子入射端子和电子倍增器部分的电子发射端子之间施加,而被施加在电子入射端子和控制电极之间,逐渐增加的电位梯度 在电子倍增部形成从光电阴极侧朝向阳极侧,在电子倍增部的电子发射端与阳极之间设置充分的电位差,能够得到稳定的检测精度。

    • A hermetically sealed vessel for a photomultiplier tube made of a side tube (2), a faceplate and a stem plate. The side tube is made by assembling a plurality of plates (80) with a curled end. An end face (81a) on a corner (81) at an open end of the side tube facing the faceplate is at a higher level than the faces other than the end face (81a). When being heated, the end face (81a) is deeply embedded into the faceplate, which enhances the joint between the side tube and the faceplate. Because the whole open end of the side tube (2) facing the faceplate is embedded into the faceplate, the joint between the side tube (2) and the faceplate is ensured, thereby improving throughput for the joining operation. The side tube is readily integral with the faceplate, which contributes to enhanced hermeticity of the sealed vessel.
    • 用于由侧管(2),面板和杆板制成的光电倍增管的气密密封容器。 侧管通过组装具有卷曲端的多个板(80)制成。 在面向面板的侧管的开口端的角部(81)上的端面(81a)比除了端面(81a)以外的面高。 当加热时,端面(81a)深深地嵌入面板中,这增强了侧管和面板之间的接合。 由于侧管(2)的面向面板的整个开口端嵌入面板中,因此确保侧管(2)与面板之间的接合,从而提高接合操作的生产量。 侧管易于与面板一体化,这有助于增强密封容器的气密性。
