Abstract: A photomultiplier tube enhanced in simplicity of mounting and flexibility, a photomultiplier tube unit enhanced in photomultiplier tube assembling efficiency when unitized, and a radiation detector enhanced in assembling efficiency for a plurality of photomulitiplier tubes. The photomultiplier (1) has an enclosed container (5) easily screw-fixed in a preset place due to a screwing means (30) provided in a stem plate (4). The result is that the photomultiplier (1) can be very easily attached or detached to enable even unskilled persons to simply mount it in a preset place accurately by screwing.

Abstract: A side tube includes a tube head, a funnel-shaped connection neck, and a tube main body integrally along a tube axis. The size of the cross section of the tube head perpendicular to the tube axis is larger than the size of the cross section of the tube main body perpendicular to the tube axis. The radius of curvature at curved corners of the tube head is smaller than the radius of curvature at curved corners of the tube main body. The length of the tube head along the tube axis is shorter than the length of the tube main body along the tube axis. A photocathode is formed in a region inside the tube head on one surface of the faceplate that is connected to the tube head. The multi-anode type photomultiper tube having the above-described structure can guide light effectively onto the photocathode, and has a high strength.

Abstract: A photomultiplier cuts out light reflection from each focusing piece or unuseful electrons from being emitted from photoelectronic face by forming an oxide film over the surface of each focusing piece of a focusing electrode. The oxide film is formed over the surface of each secondary electron emission piece of the first and second stage die node to cut out the reflection from each secondary electron emission piece, so that unuseful electrons by reflected light are prevented from being emitted from the photoelectron face. Further, a light absorbing glass partition is provided in a light receiving face plate to suppress crosstalks between channels.

Abstract: A multiple section photomultiplier tube (10) constructed as a matrix of several independent tubes (14) in one envelope (12). The photocathode (28) to dynode (31-38) spacings are isolated by a separator configuration (20) built with walls which interlock in cooperating slots, and each photocathode operates with its own independent dynode cage (26). The separation configuration (20) are buit-up of a shield structure which is composed of sheets and constitute an array of single chambers. One dynode (35) in each cage (26) is maintained electrically independent, and its connection is brought out of the envelope independently. This permits independent adjustment of the gain for each of the tube's multiple sections (14), so they can be adjusted to the same response for a standard radiation signal in an area. The entire tube can then be used to monitor a large area for radiation, and will yield the same response over its entire cathode area.

In this way, the transparency window (5) is equipped with hollow parts (8) and thick parts (23) corresponding to the non-hollow parts, the surfaces of said hollow parts (8) being covered with a light-emitting layer (2).

Abstract: A technique is provided for manufacturing a multi-anode photomultiplier tube (82) for use in positron emission tomography (PET) detectors (16). One or more optical properties within an entrance window (86) of the multi-anode photomultiplier tube (82) are altered at a focal spot (100) via a laser (94). The focal spot (100) is translated relative to the entrance window (86) for creating a three-dimensional pattern (103) within the entrance window (86). This three­dimensional pattern (103) having the one or more optical properties altered is adapted to control the spreading of optical photons (87) within the entrance window (86).
