PHOTOMULTIPLIER TUBE AND ITS USING METHOD

摘要

A plurality of conductive partitioning members (25) are provided such that each conductive partitioning member (25) is located between two corresponding adjacent anode pieces (21) to partition two adjacent channels. Since the conductive partitioning member (25) has been applied with a potential between the final stage dynode potential and anode potential, electrons emitted from each channel (A) of the final stage dynode (8) can be led appropriately to a corresponding anode piece (21) and emission of electrons from the corresponding anode piece (21) to an adjacent anode piece (21) can be suppressed. Consequently, crosstalk is prevented at the anode and resolution of energy can be enhanced for each channel.
