Hot cathode

In vacuum tubes and gas-filled tubes, a hot cathode or thermionic cathode is a cathode electrode which is heated to make it emit electrons due to thermionic emission.This is in contrast to a cold cathode, which does not have a heating element.The heating element is usually an electrical filament heated by a separate electric current passing through it. Hot cathodes typically achieve much ...

One World Marching in Time to the Cesium Clock | PSI, Inc.

Jan 05, 2018· The 1955 Cesium Atomic Clock at the National Physical Laboratory, UK. It kept time to a second in 300 years. A "cesium (-beam) atomic clock" (or "cesium-beam frequency standard") is a device that uses as a reference the exact frequency of the microwave spectral line emitted by atoms of the metallic element cesium, in particular its isotope of atomic weight 133 ("Cs-133").
