(King, Robert W.).   The phenomenon was first observed () by Thomas A. Edison as a passage of electricity from a filament to a plate of metal inside an incandescent lamp. The classical example of thermionic emission is the emission of electrons from a hot cathode into a vacuum (also known as thermal electron emission or the Edison effect) in a vacuum tube.

A vacuum tube, an electron tube, or valve or, colloquially, a tube, is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve uses the phenomenon of thermionic emission of electrons from a heated cathode and is used for a number of fundamental . In high frequency thermionic tubes of the triode, tetrode or pentode type having a cathode, an anode and one, two or three grids it is advantageous to make the grids from pyrolytic graphite, a material well known for its mechanical and thermal by: Later developments, involving the transistor, have since almost entirely replaced the vacuum tube as a low-power, low cost mass produced device. It has not however been possible to replace the specialised high-power high-frequency transmitting devices, such as the klystron, magnetron and travelling-wave tube by any solid-state : P. R.
