New atomic clock will remain precise for 300 million years
A new atomic clock has been launched in the US that is three times more accurate than the previous generation, and will not lose a second for 300 million years.
The US Department of Commerce's National Institute of Standards and Technology (NIST) launched the NIST-F2 atomic clock to serve as a new civilian time and frequency standard alongside the current NIST-F1 standard that it improves upon.
NIST-F2 has been in development for a decade, and when NIST reported the performance data to the International Bureau of Weights and Measures (BIPM) in Paris, France, the monitoring group said that it was the world's most accurate time standard.
Discussing the applications of such accuracy, NIST physicist Steven Jefferts, lead designer of NIST-F2 said:
'If we've learned anything in the last 60 years of building atomic clocks, we've learned that every time we build a better clock, somebody comes up with a use for it that you couldn't have foreseen'
