Abstract: A segmented photomultiplier tube having an electrode which, in its higher part acts as a focusing electrode for distributing photo-electrons on both sides of an axial plane, while in its lower part forming a collection cage, the photo-electrons undergo a first multiplication at the portions of the lateral walls, which are folded towards the axial plane. Apertures in a median plate of the electrode are covered by a highly transparent grid. The electrode is completed by a central partition which extends along the median plate just to the proximity of an input dynode of a laminated multiplier. A bar having a small cross-section may be provided, centered on the axial plane and receiving a potential near the potential across the photocathode. A plurality of these tubes can be arranged in a mosaic pattern for mapping luminous events.

Abstract: There is provided a photomultiplier in which a transmittance of an incident light and a photosensitivity is high and a hysteresis characteristic is excellent. Therefore, in the present invention, a photocathode 16, dynodes 17a to 17c and an anode 18 are supported between insulating material substrates 12a and 12b provided in a glass bulb 11. A transparent conductive film 19 is formed on an inside wall surface of a light entrance portion 15. The transparent conductive film 19 electrically contacts with a pad 20 which is led through a terminal 14 to the outside. The same potential as the photocathode 12 is applied through the pad 20 to the transparent conductive film 19. The incident light directly impinges on the photocathode 16 through the glass bulb 11 and the transparent conductive film 19 at a place corresponding to the light entrance portion 15. As a result, the incident light reaches the photocathode 12 with not being interfered at all, and the transmittance of the incident light is improved. Since a predetermined potential is applied to the transparent conductive film 19, the change of the potential of the inside wall surface of the glass bulb 11 is performed at high speed, and the hysteresis becomes extremely small.

Abstract: A photomultiplier tube in which the a semiconductor photodiode serves as the anode and receives the electrons from the photocathode. The particular geometry for the focusing electrodes in the tube involves a two part structure with one part, the anode focus electrode, in close proximity to the semiconductor photodiode. The second part of the focus structure is a grid focus electrode with two different diameters, located approximately midway between the photodiode and the photocathode and operating on a low voltage. Together the electrodes create a focusing electric field so that the electrons from the large area photocathode are efficiently delivered to the small area of the semiconductor photodiode. The mounting of the photodiode is also designed to act as a termination to furnish superior timing characteristics.

Abstract: An optical waveguide photocathode for converting optical signals to electrical signals has an optical waveguide, a semiconductor covering the end of the optical waveguide, a first transparent electrode disposed between the end of the waveguide and the semiconductor, and a second electrode disposed adjacent to and spaced from the semiconductor. An electric potential is applied between the first electrode and the second electrode. The waveguide, first conductor, and semiconductor are relatively pointed at the end to produce high electric field strength at the semiconductor thereby enabling semiconductors with high work functions to be used. The relatively small area of the semiconductor illuminated by the waveguide reduces the dark current, making the device more sensitive to low level signals. The device may be used in a streak tube or a photomultiplier.

Abstract: The image contrast in an image display tube having a channel plate electron multiplier (2) is improved by preventing secondary electrons emitted from the face of an input dynode (26) from straying to channels located at a relatively large distance from their origin. This is done by disposing a grid (24) at a short distance from the input dynode (26). If the grid (24) is held at a positive voltage relative to the input dynode (26), stray secondary electrons will be attracted toward the grid (24). Alternatively, if the grid (24) is held at a negative voltage relative to that of the input dynode (26), the secondary electrons will be induced to enter channels close to their origin.

Abstract translation: 具有通道板电子倍增器（2）的图像显示管中的图像对比度通过防止从输入倍增极（26）的面发射的二次电子偏离位于与其原点相对较大距离的通道而被改善。 这通过在与输入的倍增电极（26）短距离处布置网格（24）来完成。 如果电网（24）相对于输入的倍增电极（26）保持在正电压，则杂散二次电子将被吸引到电网（24）。 或者，如果电网（24）相对于输入的倍增电极（26）的电压保持在负电压，则二次电子将被诱导进入接近其原点的通道。
