- NIST-F2 abstract "NIST-F2 is a caesium fountain atomic clock that, along with NIST-F1, serves as the United States' primary time and frequency standard. NIST-F1, a caesium fountain atomic clock used since 1999, has a fractional inaccuracy of less than δf/f < 5 × 10−16. The planned performance of NIST-F2 is δf/f < 1 × 10−16. The clock will not lose a second for at least 300 million years.NIST-F2 was brought online on 3 April 2014.".
