Are Atomic Clocks Affected by Ambient Temperature?

Click For Summary
SUMMARY

Atomic clocks, specifically the NIST-F1 Cesium Fountain Atomic Clock, are not directly affected by ambient temperature in terms of timekeeping accuracy. However, their ultimate precision is influenced by temperature due to the broadening of atomic transition lines caused by heating the atoms to form a gas. Newer atomic clock designs utilize laser traps to hold atoms at low temperatures, significantly enhancing accuracy by minimizing this temperature-related broadening.

Are atomic clocks such as the NIST-F1 Cesium Fountain Atomic Clock

http://tf.nist.gov/cesium/fountain.htm"

sensitive to the ambient temperature

Or do they keep very accurate time regardless of the ambient temperature?

They aren't affected by the outside temperature, but their ultimate precision does depend on temperature. The atoms used are heated to form a gas and because of the temperature the lines of atomic transitions are slightly broadened - some newer designs use atoms held (almost) motionless at low temperatures in laser traps to improve the accuracy.
