Abstract: A microchannel plate assembly includes a plurality of microchannel plates that are aligned along a common axis and coupled together. The microchannel plates each have an object-side surface and an image-side surface and the assembly has respective interfaces between the image-side surface and the object-side surface of adjacent microchannel plates. At least one ion barrier film is disposed on at least one of the microchannel plates, but only on the object-side surfaces in the interfaces.

Abstract: A metal side tube (2), a glass faceplate (3), and a stem plate ( ) constitute a hermetically sealed vessel (5) for a photomultiplier tube. An edge portion (20) is provided at on open end (A) of the side tube (2). The edge portion (2) is embedded in the faceplate (3) in such a manner as to strike on the faceplate (3). Accordingly, high hermeticity at a joint between the side tube (2) and the faceplate (3) is ensured. The edge portion (20) extends upright in an axial direction of the side tube (2), so that the edge portion (20) can be embedded as close to a side face (3c) of the faceplate (3) as possible. This structure increases an effective sensitive area of the faceplate (3) to nearly 100%, and decreases dead area as close to 0 as possible. As described above, the photomultiplier tube (1) according to the present invention has enlarged effective sensitive area of the side tube (3) and enhanced hermeticity of the joint between the faceplate (3) and the side tube (2).

Abstract: A photomultiplier uses an avalanche photodiode as a position-sensitive anode. The envelope of the photomultiplier has a flat input end. Electrically conductive regions mounted to the input end are configured to produce at the input end a potential distribution characteristic of a photomultiplier with a spherical-type input end as measured in a transverse plane immediately adjacent the spherical-type input end. A photocathode is located inside the photomultiplier and is electrically connected to the electrically conductivew regions. Advantageously, the envelope has flat sides and a square cross-section; in this instance, conductors are run along the sides to produce within the envelope a potential distribution characteristic of a photomultiplier which is cylindrical in cross-section, as measured at flat surfaces having the same shape as the envelope.

Abstract: Reduced ion feedback in an electron multiplier (EM) is achieved by applying a higher than normal bias voltage to the EM and degassing the EM with a relatively high concentration of self-generated particles as a result of the applied bias voltage.

Abstract: An image intensifier tube and a method of making same are disclosed wherein veiling glare caused by the amplification of off axis light is reduced. Included is a non-reflective, near infrared light absorbing first layer formed on the face plate of the tube adjacent any surface at which off-axis light could otherwise be reflected to the photoemissive device associated with the face plate and an electronically conductive second layer formed on top of the first layer. Such coatings are preferably formed by sputter deposition.

Abstract: In a laminated channel plate electron multiplier, an apertured metal sheet (32) is disposed at a small distance (30 .mu.m) from the outer surface of the input dynode and is used to provide a small negative field for turning back stray secondary electrons which have sufficient energy to follow trajectories across the input side of the input dynode. More particularly, the areas between the apertures of the input dynode (22) are masked by a material (34) having a secondary electron emission coefficient of less than 2, which material (34) is provided on the outer surface of the apertured metal sheet (32), the metal sheet (32) being spaced from the input dynode (22) by an insulating material (36). A potential of the order of -10 V relative to the input dynode is applied to the apertured metal sheet (32).
