CäsiumOszillatoren
CäsiumOszillatoren, often referred to as cesium oscillators, are a type of atomic clock that utilizes the energy transition of cesium atoms to generate highly accurate timekeeping signals. The fundamental principle behind their operation is the specific frequency of microwave radiation required to induce a transition between two hyperfine energy levels of the cesium-133 atom's ground state. This frequency, defined as exactly 9,192,631,770 Hertz, serves as the basis for the definition of the second.
A cesium oscillator typically consists of a cesium beam tube, a microwave cavity, and electronic components
The accuracy and stability of cesium oscillators are exceptional, making them the primary standard for time
