A lot vs. Alot: 9 Grammatical Pitfalls
|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.
