Doppler cooling limit:Laser-Cooled Atoms: Cesium – Uncertain Principles Archive,03-09-2013· Cesium was a very early target for laser cooling experiments, because of its importance as the standard reference for the SI second. Back in the 60’s or so, Jerrold Zacharaias had pointed out that a lot of problems with atomic clocks could be made better by orienting the clock vertically, and letting the atoms go up and fall back down through a single microwave cavity.Caesium - Wikipedia,Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium.

    Atomic clock - Wikipedia

    In August 2004, NIST scientists demonstrated a chip-scale atomic clock. According to the researchers, the clock was believed to be one-hundredth the size of any other. It requires no more than 125 mW, making it suitable for battery-driven applications. This technology became available commercially in 2011. Ion trap experimental optical clocks are more precise than the current caesium standard.NIST-F1 Cesium Fountain Atomic Clock | NIST,It is now approximately ten times more accurate than NIST-7, a cesium beam atomic clock that served as the United State's primary time and frequency standard from 1993-1999. Technical Description NIST-F1 is referred to as a fountain clock because it uses a fountain-like movement of atoms to measure frequency and time interval.Caesium - Atomic Mass - Atomic Weight - Cs,Caesium is a chemical element with atomic number 55 which means there are 55 protons and 55 electrons in the atomic structure.
