摘要： The present invention relates to a photomultiplier that realizes significant improvement of response time properties with a structure enabling mass production. The photomultiplier comprises a sealed container, and the sealed container includes a hollow body section, extending along a tube axis, and a faceplate. The faceplate has a light incidence surface and a light emission surface on which a photocathode is formed. In particular, the light emission surface is constituted by a flat region, and a curved-surface processed region that is positioned at a periphery of the flat region and that includes edges of the light emission surface. A surface shape of the peripheral region of the light emission surface of the faceplate is thus intentionally changed in order to adjust the angles of emission of photoelectrons from the photocathode positioned at the peripheral region. Thus, the spread of transit times of photoelectrons propagating from the photocathode to a first dynode is thus reduced effectively and made not to depend on the emission positions of the photoelectrons.

摘要： The present invention concerns a photomultiplier having a lamination structure of fine mesh dynodes arranged at predetermined intervals, capable of detecting photons even in a high magnetic field. This photomultiplier is arranged so that hollow pipes penetrating electrodes for supporting the fine mesh dynodes define the lamination structure of an electron multiplier unit. This arrangement permits the intervals between the fine mesh dynodes to be accurately controlled, thereby obtaining the photomultiplier production errors of which are well suppressed and preventing that the fine mesh dynodes are ripped.

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： In an electron tube, an insulating tube protrudes inside an envelope. One end of the insulating tube is connected to the envelope. An avalanche photo diode (APD) is provided on the other end of the insulating tube. A ground voltage is applied to the envelope and a positive high voltage is applied to the APD. Photoelectrons which are emitted in response to an incident light on a photocathode are converged by an electrical field in the envelope and enter the APD. Thereafter, the incident photoelectrons are amplified and detected. Since a positive high voltage is not exposed to the envelope, the electron tube can easily be handled and is excellent in safety.

摘要： An insulating tube has one end and another end. An avalanche photodiode (APD) is provided outside the one end of the insulating tube. The another end of the insulating tube is air-tightly connected to an outer flange through a stem inner wall. Capacitors electrically connected to the APD are provided in the insulating tube. The capacitors remove direct current components from signals that the APD generates when detecting electrons.

摘要： A photocathode is formed on a predetermined portion of the internal surface of an envelope of an electric tube. An avalanche photodiode (APD) is provided inside the envelope. The APD is surrounded by a cover and a tubular inner wall. A manganese bead and an antimony bead serving as evaporation sources are disposed in the vicinity outside the inner wall. The manganese bead and the antimony bead are surrounded by a tubular outer wall. The manganese bead and the antimony bead generate metal vapor to thereby form the photocathode. In forming the photocathode, the cover, inner wall, outer wall prevent the metal vapor from being deposited on the APD or an unintended portion inside the electron tube.
