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