Electron multiplier for use in photoelectric electron-multiplier tube, has anode placed between dynode before last dynode and last dynode, where last dynode has conductors electrically insulated with respect to each other

摘要

The multiplier has a piling common to channels and having a dynode, intermediate dynodes, a dynode (2) before last dynode and a last dynode (11) in a direction of path of electrons. An anode (3) is placed between the dynodes (2, 11). The dynode (11) has conductors (87-89, 97-99, 107-109) electrically insulated with respect to each other, where each insulated conductor has an electric connection. An independent claim is also included for a photomultiplier tube.
