ABSTRACT:
A dynode constituting an electron multiplier or a photomultiplier may be provided with eight rows of channels each defined by an outer frame and a partitioning part of the dynode. In each channel, a plurality of electron multiplying holes may be arranged. In specified positions of the outer frame and the partitioning part of the dynode, glass receiving parts wider than the outer frame and the partitioning part may be provided integrally with the dynode. 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. Each dynode may be formed after the dome-like glass part may be bonded to the glass receiving part.
