Electron-multiplier meaning

An electronic component used in photomultipliers, particle detectors, and electron microscopes, in which single electrons may produce a large current by inducing secondary emission of electrons when they strike an anode.

A device that amplifies a stream of electrons by causing it to strike electrodes at successively higher potentials: secondary electrons produced at each electrode increase the quantity of electrons in the stream.

An electrical component in which a single electron can create a large current flow. Electron multipliers are used in photomultipliers, particle detectors, and electron microscopes. &diamf3; In tube electron multipliers , electrons released from a cathode collide with a dynode or anode, causing release of more electrons through secondary emission ; this process is generally repeated through a number of stages to achieve great amplification of current. Electron multipliers are also called electron amplifiers.
