摘要： To reduce the size of a photomultiplier tube (1), a side tube (2) is fixedly secured by welding to a stem plate (4) while an inner surface (2c) of the lower portion (2a) of the side tube (2) is maintained to be in contact with an outer edge (4b) of the stem plate (4). As a result, there is no projection like a flange at the lower portion of the photomultiplier tube (1). Therefore, though it is difficult to perform resistance welding, the outside dimensions of the photomultiplier tube (1) can be decreased, and the side tubes (9) can densely abut to one another even if the photomultiplier tubes (2) are arranged when applied. Hence, high-density arrangement of photomultiplier tubes (1) are realized by assembling metallic stem plate (4) and the side tube (2) by, for example, laser welding.
摘要翻译：为了减小光电倍增管（1）的尺寸，侧管（2）通过焊接牢固地固定在杆板（4）上，而侧管（2）的下部（2a）的内表面（2c））保持与杆板（4）的外边缘（4b）接触。结果，在光电倍增管（1）的下部没有像凸缘那样的凸起。因此，虽然难以进行电阻焊接，但是即使在施加光电倍增管（2）时，也可以减小光电倍增管（1）的外部尺寸，并且侧管（9）可以彼此紧密地邻接。因此，光电倍增管（1）的高密度配置通过例如激光焊接组装金属杆板（4）和侧管（2）来实现。

摘要： A photomultiplier tube has a side tube with a stem plate fixed on one end and a faceplate fixed on the other. The side tube is formed of metal, and at least the portion of the stem plate contacting the metal side tube is formed of metal. The side tube and stem plate are fused together by laser welding or electron beam welding to form an airtight vessel, such that the outer edge of the stem plate does not protrude further externally than the outer surface of the side tube.

摘要： A photomultiplier tube unit including photomultiplier tubes densely assembled and thereby having an improved light sensing efficiency. The outer surfaces (2b) of metal side tubes (2) of photomultiplier tubes (1) are in facial contact with one another, and thereby a high-density arrangement of photomultiplier tubes (1) are achieved. The side tubes (2) can be electrically connected to one another, and therefore the side tubes (2) can be easily made equipotential. As a result, it is unnecessary to electrically connect the stem pin (10) to the side tube (2) of each photomultiplier tube (1), facilitating the assembling of the photomultiplier tube unit. When a required photomultiplier tube (1) in a device (e.g., a gamma camera) having thus-united multiple photomultiplier tubes is replaced with a new one, the troublesome work of replacing photomultiplier tubes one by one is obviated, simplifying the replacement work.

Glass parts may be bonded to all the glass receiving parts. The glass parts may be bonded by applying glass to the glass receiving parts and hardening the glass and each may have a generally dome-like convex shape.

摘要： A photomultiplier tube, a photomultiplier tube unit, and a performance-improved radiation detector for increasing a fixing area of a side tube in a faceplate while increasing an effective sensitive area of the faceplate. In the photomultiplier tube, a side face (3c) of the faceplate (3) protrudes outward from an outer side wall (2b) of a metal side tube (2), so that a light receiving area for receiving light passing through a light receiving face (3d) of the faceplate (3) is increased. The overhanging structure of the faceplate (3) is conceived based on a glass refractive index. The overhanging structure is aimed to receive light as much as possible which has not been received before. When the metal side tube (2) is fused to the glass faceplate (3), a fusing method is adopted due to joint between glass and metal. Joint operation between the faceplate (3) and the side tube (2) is reliably ensured. Accordingly, the overhanging structure of the faceplate (3) is effective.

摘要： A metal side tube (2), a glass faceplate (3), and a stem plate (4) 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).
