Title:

PHOTOMULTIPLIER

Document Type and Number:

WIPO Patent Application WO/1999/063575

Kind Code:

A1

Abstract:

To reduce the size of a photomultiplier (1), a side tube (2) is secured by welding to a stem plate (4) while an inner wall face (2c) of the lower end (2a) of the side tube (2) is maintained to be in contact with an edge face (4b) of the stem plate (4). As a result, there is no projection like a flange at the bottom of the photomultiplier (1). Therefore, though it is difficult to perform resistance welding, the outside dimensions of the photomultiplier (1) can be decreased, and the side tubes (9) can densely abut to one another even if the photomultipliers (2) are arranged when applied. Hence, high-density arrangement of photomultipliers (1) are realized by assembling metallic stem plate (4) and the side tube (2) by, for example, laser welding.
