| 20090045741 | Photomultiplier - The present invention relates to a photomultiplier having a fine structure capable of realizing high detection accuracy by effectively suppressing cross talk among electron-multiplier channels. 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. | 02-19-2009 |
| 20090218944 | Photomultiplier - 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. | 09-03-2009 |

| 20090305450 | METHOD FOR MANUFACTURING PHOTOELECTRIC CONVERTING DEVICE - The present invention relates to a manufacturing method of obtaining a photoelectric converting device which can sufficiently maintain airtightness of a housing space for photocathode without degradation of the characteristics of the photocathode. In accordance with the manufacturing method, on the side wall end face of a lower frame and a bonding portion of an upper frame forming an envelope of the photoelectric converting device, a multilayered metal film of chromium and nickel is formed. In a vacuum space decompressed to a predetermined degree of vacuum and having a temperature not more than the melting point of indium, these upper and lower frames introduced therein are brought into close contact with each other with a predetermined pressure while sandwiching indium wire members, and accordingly, an envelope having a housing space whose airtightness is sufficiently maintained is obtained. | 12-10-2009 |
