NISTF4

The NIST-F4 atomic clock, developed by the National Institute of Standards and Technology (NIST), is one of the most accurate timekeeping devices ever made. If it had started running during the age of dinosaurs, it would still be accurate to within just one second today.

The clock works by tracking the natural vibrations of cesium atoms. These atoms are cooled and tossed upward in a fountain-like motion. As they rise, they pass through microwave radiation, which causes them to "tick." The clock counts 9,192,631,770 of these atomic ticks every second to measure time with extreme precision.

NIST-F4 helps keep the official U.S. time and plays a crucial role in systems like GPS, global communications, and financial transactions-ensuring they stay perfectly in sync. It's currently under review to be officially certified as one of the most accurate clocks in the world.

The NIST-F4 Atomic Clock: A New Benchmark in Precision Timekeeping

Developed by the National Institute of Standards and Technology (NIST), the NIST-F4 atomic clock ranks among the most precise timekeeping instruments ever built. Remarkably, if it had been running since the time of the dinosaurs, it would still be accurate to within just one second today.

This extraordinary accuracy comes from tracking the vibrations of cesium atoms. Cooled and launched upward in a fountain-like arc, the atoms pass through microwave radiation that makes them “tick.” The clock counts exactly 9,192,631,770 of these atomic ticks per second to maintain flawless time.

NIST-F4 plays a vital role in keeping official U.S. time and is essential to technologies like GPS, global communications, and financial networks—ensuring seamless synchronization across the globe. It is currently undergoing review for certification as one of the most accurate clocks ever made.
