摘要： A photomultiplier includes a photoelectric surface for photoelectrically converting incident light and emitting electrons, and a plurality of stages of dynodes for multiplying the electrons. The photomultiplier includes a first dynode array including box-and-grid dynodes arranged in a vessel and a second dynode array including in-line dynodes arranged in the vessel. A dynode having a curved secondary electron emitting layer opposes both a secondary electron emitting layer of a last stage dynode of the first dynode array and a secondary electron emitting layer of a first-stage dynode of the second dynode array.

摘要： This invention relates to an electron multiplier unit and others enabling cascade multiplication of electrons through successive emission of secondary electrons in multiple stages in response to incidence of primary electrons. The electron multiplier unit has a first support member provided with an inlet aperture for letting primary electrons in, and a second support member located so as to face the first support member. The first support member is provided with a focusing electrode functioning to alter trajectories of the primary electrons, in order to guide the primary electrons to the inlet aperture. These first and second support members hold an electron multiplication section for the cascade multiplication and an anode. The electron multiplication section comprises at least a first dynode of a box type and a second dynode having a reflection type secondary electron emission surface located so as to face the first dynode and arranged to receive secondary electrons from the first dynode and to emit secondary electrons to a side where the first dynode is located. The anode is located at a position where the secondary electrons emitted from the first dynode do not directly arrive, and the second dynode alters a travel path of secondary electrons so as to be kept in a space between the first and second support members.

摘要： Support electrodes are provided for individually supporting a plurality of dynodes arranged inside of a vessel of an electron tube, such as photomultiplier tube. A black spacer formed from a ceramic material is disposed between the support electrodes. The black spacers are formed with elemental composition having content of MnO suppressed to 3 wt % or less. Current leaks, which are the cause of dark current, and abnormal generations of light during photomultiplication can be reduced, thereby improving the signal-to-noise ratio of the electron tube.

摘要： This invention relates to a semiconductor photo-electron-emitting device for emitting photoelectrons excited from the valence band to the conduction band by incident photons on a semiconductor layer. The device includes a Schottky electrode formed on the emitting surface on a surface of the semiconductor layer, and a conductor layer formed on a surface opposite to the emitting surface. A set bias voltage is applied between the Schottky electrode and the conductor layer to accelerate photoelectrons generated by the excitation of incident photons to the emitting surface and to transfer the accelerated photoelectrons from an energy band of a smaller effective mass to an energy band of a larger effective mass.

摘要： A photomultiplier for receiving incident light on a photocathode, and cascade-multiplying electrodes emitted from the photocathode by a secondary electronic effect of a plurality of dynodes, whereby the incident light is detected. The photomultiplier includes a slowing-down electrode for decelerating those of secondary electrons emitted from a dynode on the first stage to a dynode on the second stage which have a higher speed. Because of the slowing-down electrode the secondary electrons having a higher speed are selectively decelerated, whereby a transit time spread of the secondary electrons emitted from parts of the first stage-dynode to the second stage-dynode is relatively decreased.

摘要： An electron lens electrode for guiding photoelectrons emitted from a photocathode to an electron multiplier section is arranged between the photocathode and the light-incident portion of a sealed container, and an opening is formed at a portion of the electron lens electrode opposing the light-incident portion. Incident light reaches the photocathode through the opening without being scattered or absorbed at all. The transmittance of light incident on a photomultiplier is improved, and the output waveform is uniformed, resulting in an improved S/N ratio.
