Title:
光電子増倍管及びその製造方法
Document Type and Number:
Japanese Patent JP4132305
Kind Code:
B2
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.
