An atomic clock is based on a system of atoms which may be in one of two possible energy states. A group of atoms in one state is prepared, then subjected to microwave radiation. If the radiation is of the correct frequency, a number of atoms will transition to the other energy state.
NIST-F1. NIST-F1 is a cesium fountain clock, a type of atomic clock, in the National Institute of Standards and Technology (NIST) in Boulder, Colorado, and serves as the United States' primary time and frequency standard. The clock took less than four years to test and build, and was developed by Steve Jefferts and Dawn Meekhof of the Time and ...
Department of Defense master clock. United States Naval Observatory. Washington, D.C. United States. 18 cesium atomic clocks and 4 hydrogen maser clocks. Cs, H. National Institute of Information and Communications Technology. Koganei, Japan [ 13 ] Optical lattice clock.
The study of physics itself could be revolutionized by using nuclear clocks alongside atomic clocks, according to Zhang. Monitoring and comparing frequency ratios in the two types of clocks over ...
NIST physicists Steve Jefferts (foreground) and Tom Heavner with the NIST-F2 cesium fountain atomic clock, a civilian time standard for the United States. NIST-F2 is a caesium fountain atomic clock that, along with NIST-F1, serves as the United States ' primary time and frequency standard. [1] NIST-F2 was brought online on 3 April 2014. [1][2]
A chip scale atomic clock (CSAC) is a compact, low-power atomic clock fabricated using techniques of microelectromechanical systems (MEMS) and incorporating a low-power semiconductor laser as the light source. The first CSAC physics package was demonstrated at the National Institute of Standards and Technology (NIST) in 2003, [1] based on an ...
