摘要： A vacuum vessel (18) is configured by hermetically joining a faceplate (13) with one end of a side tube (15) and hermetically joining a stem (50) with another end via a ring-shaped side tube (37). Within the vacuum vessel (18), a focus electrode (17), dynodes (Dy1-Dy9), an anode (25), and a dynode (Dy10) are arranged from the side of a photocathode (14) provided to the faceplate (13). The dynode (Dy10) is supported on spacers (33) and a positioning protrusion (31) provided on the stem (50). The anode (25) is placed on support members (21). The focus electrode (17), the dynodes (Dy1-Dy9), and the anode (25) are stacked with inter-layer members (23) interposed therebetween, the inter-layer members (23) being located coaxially with the support members (21), to ensure high anti-vibration performance. Because the anode (25) and the dynode (Dy10) have no insulating body therebetween, light emission is suppressed and noises can be reduced.

摘要： 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.

摘要： A vacuum vessel is configured by hermetically joining a faceplate (13) to one end of a side tube (15) and a stem (29) to the other end via a tubular member (31). A photocathode (14), a focusing electrode (17), dynodes (Dy1-Dy12), a drawing electrode (19), and anodes (25) are arranged within the vacuum vessel. The tubular member (31) is disposed on the periphery of the stem (29), and supporting pins (21) and lead pins (47) penetrate and are fixed to an extending section (32) that protrudes from the tubular member (31). The supporting pins (21) and the lead pins (47) are arranged in cutout portions (49, 24) of the dynodes (Dy1-Dy12) and the drawing electrode (19), thereby allowing effective areas of each electrode to be enlarged. Further, protuberant sections (33) are formed on the connecting sections of each pin with the stem (29), thereby facilitating thickness control of the stem.
