Cesium Atomic Clock Accuracy

Cesium Atomic Clock Accuracy. To turn the cesium atomic resonance into an atomic clock, it is necessary to measure one of its transition or resonant frequencies accurately. Very accurate clocks can be constructed by locking an electronic oscillator to the frequency of an atomic transition.

The best way of understanding how an atomic (cesium) clock works, in my opinion, is to divide it to a couple of individual parts. Atomic clocks keep time by the vibrations of their atoms, which is more than 9 billion vibrations a second in the most commonly used cesium (also spelled as caesium) atomic clock. Other electronics in the atomic clock count this frequency.

Crystal clock accuracy is defined in terms of ppm or parts per million and it gives a convenient way of comparing accuracies of different crystal specifications. Atomic clocks are designed to detect this frequency, most of them today using atomic fountains; .is a cesium fountain atomic clock developed at the nist laboratories in boulder, colorado. Today's atomic clocks mostly still use cesium.
