Thermion (Noun)
Meaning
An electrically charged particle (electron or ion) emitted by a substance at a high temperature.
Classification
Nouns denoting natural objects (not man-made).
Examples
- The thermion emitted by the heated filament was accelerated by the electric field and collided with the anode.
- At high temperatures, the metal surface emitted a stream of thermions that contributed to the electrical conductivity of the gas.
- The thermion emission from the cathode was enhanced by the application of a strong electric field.
- In the thermionic converter, the thermions emitted by the heated cathode were collected by the anode, generating an electric current.
- The thermion emission current from the metal surface was measured as a function of temperature to determine the work function of the material.
