  1. atomic clock

    An atomic clock is a type of clock that uses the vibrations of atoms to measure time with extreme precision. The most common type of atomic clock is based on the vibrations of cesium atoms, achieving accuracy within a few billionths of a second per day. These clocks form the basis for international time standards and are used in global navigation satellite systems, research, telecommunications and other scientific endeavors.

  1. Atomic clock

    An atomic clock is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS. The principle of operation of an atomic clock is not based on nuclear physics, but rather on atomic physics and using the microwave signal that electrons in atoms emit when they change energy levels. Early atomic clocks were based on masers at room temperature. Currently, the most accurate atomic clocks first cool the atoms to near absolute zero temperature by slowing them with lasers and probing them in atomic fountains in a microwave-filled cavity. An example of this is the NIST-F1 atomic clock, the U.S. national primary time and frequency standard. The accuracy of an atomic clock depends on the temperature of the sample atoms—colder atoms move much more slowly, allowing longer probe times, as well as having reduced collision rates—and on the frequency and intrinsic width of the electronic transition. Higher frequencies and narrow lines increase the precision.−914
