摘要： An envelope has a glass bulb body and a cylindrical glass bulb base. The glass bulb body includes an upper hemisphere and a lower hemisphere. The upper hemisphere is curved in a substantially spherical shape. The lower hemisphere is substantially curved in a spherical shape and connects the upper hemisphere and glass bulb base. A photocathode is formed on the inner surface of the glass bulb body. An avalanche photodiode is disposed on the glass bulb body side relative to an intersection between an imaginary extended curved surface of the lower hemisphere within the glass bulb base and an axis. When light enters the photocathode, electrons are emitted from the photocathode. The electrons are converged at the position above and in the vicinity of the APD by an electrical field in the electron tube, so that the electrons enter the APD in an efficient manner and are detected satisfactorily.

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.

摘要： The invention relates to a photocathode and the like having such structure for holding a photocathode plate on a light transparent member with good reliability and workability. In the photocathode, claw portions of a holding member fixed to the light transparent member is pressed against the lower surface of a supporting plate so that a photocathode plate is sandwiched between the light transparent member and the supporting plate. Thus, the supporting plate is pressed against the photocathode plate, so that the photocathode plate is pressed against the light transparent plate by the supporting plate. This allows the photocathode plate to be held reliably by the light transparent member. This simple configuration further provides good workability in assembling.
摘要翻译：本发明涉及一种具有这样的结构的光电阴极等，该光电阴极等具有良好的可靠性和可加工性的将光电面板保持在透光构件上。在光电阴极中，固定在透光构件上的保持构件的爪部被压靠在支撑板的下表面上，使得光电阴极板夹在透光构件和支撑板之间。因此，支撑板被压在光电阴极板上，使得光电阴极板通过支撑板压靠在透光板上。这允许光电阴极板被透光构件可靠地保持。这种简单的配置进一步提供了良好的组装可操作性。

摘要： In an electron tube, one end of an insulating tube is protruded toward the inside of an envelope, and an avalanche photodiode (APD) is provided on the one end of the insulating tube. Another end of the insulating tube is connected to an outer stem of the envelope. Alkali sources are provided inside the envelope. The alkali sources are disposed inside the envelope and generates alkali metal vapor to thereby form a photocathode on a predetermined part of the internal surface of the envelope. The alkali sources and insulating tube are isolated from each other by a separating member. When the electron tube is manufactured, the alkali metal vapor that is generated from the alkali sources is not deposited on the insulating tube due to existence of the separating member. This prevents voltage resistance between the envelope and APD from being decreased and the electrical field in the electron tube from being adversely affected, thereby preventing incident efficiency of electrons to the APD from being decreased.
