摘要： A glass container has a faceplate, a side tube, and a bottom. A photocathode is formed on the inner side of the faceplate. The glass container includes a first dynode, a second dynode, a screen focusing electrode, a dynode array, and an anode. The screen focusing electrode consists of a first screen, a second screen, a flat plate, and an aperture. The first screen is provided on the first dynode side of the aperture and extends across the lower end of the first dynode towards the photocathode. The second screen is provided on the second dynode side of the aperture and extends across the lower end of the second dynode towards the photocathode. A Venetian blind type is provided as the dynode array. The first dynode, the second dynode, the dynode array, and the anode are maintained at the potential which is higher than that of the photocathode. Electrons emitted from the photocathode in response to incident light thereon efficiently impinge on the dynodes regardless of where the electrons are emitted. The electrons are multiplied and then detected by the anode.

摘要： In this photomultiplier tube 1, light incident on a light-receiving faceplate 3 is converted into photoelectrons by a photosensitive surface 3a, and the photoelectrons strike a dynode 4 to emit many secondary electrons. The secondary electrons are then collected by a mesh-like anode 5. Since the anode 5 is disposed to be parallel to the photosensitive surface 3a, the photoelectrons emerging from the photosensitive surface 3a can easily pass through a mesh portion 5a, and many photoelectrons can be made to strike the dynode 4. As the number of photoelectrons incident on the dynode 4 increases, the number of secondary electrons from the dynode 4 increases. This improves the gain characteristics of the photomultiplier tube 1. Since a secondary electron emission surface 4a of the dynode 4 is tilted with respect to the anode 5, photoelectrons having passed through the anode 5 obliquely strike the secondary electron emission surface 4a of the dynode 4.
摘要翻译：在该光电倍增管1中，入射到受光面板3上的光被光敏表面3a转换为光电子，并且光电子撞击倍增极4以发射许多二次电子。二次电子然后被网状阳极5收集。由于阳极5被设置为平行于感光表面3a，从感光表面3a出射的光电子可以容易地通过网孔部分5a，并且许多光电子体随着入射到倍增极4上的光电子的数量增加，来自倍增极4的二次电子的数量增加。这改善了光电倍增管1的增益特性。由于倍增极4的二次电子发射表面4a相对于阳极5倾斜，所以通过阳极5的光电子倾斜地撞击倍增极4的二次电子发射表面4a 。
