electron multiplier
noun
Electronics.
- a vacuum tube containing a number of dynodes that serve to amplify the flow of electrons from the cathode by means of secondary emission.
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
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.
- â—† 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.
