In addition to increased accuracy, the development of chip-scale atomic clocks has expanded the number of places atomic clocks can be used. In August 2004, NIST scientists demonstrated a chip-scale atomic clock that was 100 times smaller than an ordinary atomic clock and had a much smaller power consumption of 125 mW .
This is a list of some experimental laboratory atomic clocks worldwide. This list is incomplete; you can help by adding missing items. (March 2013) Name
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
In 2013 Bathys Hawaii [52] introduced their Cesium 133 Atomic Watch [53] [54] [55] the first watch to keep time with an internal atomic clock. Unlike the radio watches described above, which achieve atomic clock accuracy with quartz clock circuits which are corrected by radio time signals received from government atomic clocks, this watch ...
The Bulletin of Atomic Scientists tracks man-made threats and focuses on three main hazard areas — nuclear risk, climate change and disruptive technologies — to determine the clock's placement.
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 fewer than four years to test and build, and was developed by Steve Jefferts and Dawn Meekhof of the Time and ...
