The evaluated accuracy u B reports of various primary frequency and time standards are published online by the International Bureau of Weights and Measures (BIPM). In May 2013 the NIST-F1 cesium fountain clock reported a u B of 3.1 × 10 −16. However, that BIPM report and the other recent reports are based on an evaluation that dates to 2005. [4]
The first caesium clock was built by Louis Essen in 1955 at the National Physical Laboratory in the UK [1] and promoted worldwide by Gernot M. R. Winkler of the United States Naval Observatory. Caesium atomic clocks are one of the most accurate time and frequency standards, and serve as the primary standard for the definition of the second in ...
The rack mounted units in the background are HP 5071A cesium beam clocks. The black units in the foreground are Sigma-Tau MHM-2010 hydrogen maser standards. An atomic clock is a clock that measures time by monitoring the resonant frequency of atoms. It is based on atoms having different energy levels.
In 1967, his cesium "flying clock" was used in flights around the world to bring timekeeping accuracy down to about 0.1 microseconds. In 1972 and 1976, these same clocks were used in flight tests verifying Albert Einstein's theories of special and general relativity , [ 4 ] showing that time does slow down the faster you move or the closer you ...
