Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic clock that has set new world records for both precision and stability-- key metrics for the performance of a clock.

New Compact Atomic Clock Design Uses Cold Atoms To Boost Precision
2013-11-06 12:03:09

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability.

An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters.


Word of the Day
dittany
  • An aromatic woolly plant (Origanum dictamnus) native to Crete, formerly believed to have magical powers.
The word 'dittany' may come from the name of Mount Diktē in Crete, where it was supposed to grow.
