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 hermetically sealed vessel for a photomultiplier tube made of a side tube (2), a faceplate and a stem plate. The side tube is made by assembling a plurality of plates (80) with a curled end. An end face (81a) on a corner (81) at an open end of the side tube facing the faceplate is at a higher level than the faces other than the end face (81a). When being heated, the end face (81a) is deeply embedded into the faceplate, which enhances the joint between the side tube and the faceplate. Because the whole open end of the side tube (2) facing the faceplate is embedded into the faceplate, the joint between the side tube (2) and the faceplate is ensured, thereby improving throughput for the joining operation. The side tube is readily integral with the faceplate, which contributes to enhanced hermeticity of the sealed vessel.

Abstract: A photocathode and an electron tube in which the photocathode plate can be securely fixed without using any adhesive. Even under the severe condition that a high vibration resistance is required or thermal stress occurs because of great temperature variation, it can be used widely for an image intensifier, a streak tube, or a photomultiplier. The photocathode plate of the photocathode is sandwiched between a faceplate and a support plate. First pins embedded in the faceplate are joined to the support plate. Therefore, the photocathode plate can be readily fixed securely to the faceplate without using any adhesive.

Abstract: A readout circuit for an imaging detector that improves resolution and increases field of view in a display compared to traditional readout circuits. The readout circuit comprises two or more amplifiers that receive a row or column of outputs from the imaging detector. Subtraction circuitry, included in the readout circuit, receives the signals from the amplifiers, determines a fractional value of the sum of the signals, and subtracts the fractional value from each signal thereby producing both positive and negative signals. A rail to rail amplifier operating from a signale voltage supply eliminates one polarity of the signals making the signals unipolar. A combining circuit receives the unipolar signals and combines them to produce two readout circuit outputs that are transmitted to a computer to be displayed.

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: An end-on photomultiplier tube has a fused quartz dome covering its light-receiving face plate or window and further has its photocathode interfaced with the window and with the tube vacuum. The dome is a partial hemisphere so shaped that, in combination with the window thickness, the two members form a true hemisphere centered on the cathode. An incident light beam passing through the dome and directed onto the cathode center is reflected back into the dome from both the inner and outer interfaces of the cathode. The exterior surface of the dome lying in the path of these reflected beams is aluminized and, since the radius of curvature of the dome is centered on the cathode, these reflected beams are normal to the aluminized surface and thus re-reflected and reimaged back onto the cathode center. The arrangement achieves quantum efficiency gains by permitting a multiple photon traversal of the cathode and by controlling the angle of incidence to promote maximum interface reflectance. Also the reduction in size of the effective photocathode area minimizes photomultiplier dark current.
