British Dictionary definitions for electron multiplier

electron multiplier

noun

physics a device for amplifying and measuring a flux of electrons. Each electron hits an anode surface and releases secondary electrons that are accelerated to a second surface; after several such stages a measurable pulse of current is obtained

Scientific definitions for electron multiplier

electron multiplier

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.♦ 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.
