These atoms oscillate between two energy. In the splitting of the frequencies in the D line of the cesium atom we will see 9.192631770 GHz, this is one second exactly, (or what humans have chosen to be. Further improvement is practically impossible to achieve with this method of electron excitation. Ready to learn more? Contact your local Microsemi sales office to find the right clocks and frequency reference products and technologies for your needs. The caesium atomic clock operates by utilizing vapourised caesium-133 atoms that move between magnets at each end. Current cesium atomic clocks already use a very narrow resonance strontium atomic clocks achieve a higher accuracy with only one second in 15 billion years. Known as the SA.45s Chip Size Atomic Clock (CSAC), it could be yours for just 1500. (Courtesy: Symmetricom, Inc.) Researchers in the US have developed the world’s smallest commercial atomic clock. Microsemi is also the leading provider of gas-cell atomic clocks, including the Chip Scale Atomic Clock (CSAC), the world’s smallest and lowest-power atomic clock, and the Miniature Atomic Clock (MAC). The worlds first commercially available chip-scale atomic clock: the Symmetricom SA.45s. They give the standard measure of time: the electron resonance frequency of the caesium atom is 9,192,631,770 cycles per second. These clocks are a vital part of the internetand mobile phone networks, as well as Global Positioning System (GPS) satellites. On a weighted average basis, Microsemi atomic clocks provide over 90% of the input to Universal Coordinated Time (UTC). Microsemi is the world’s only commercial provider of cesium beam-tube clocks, used in national labs around the world. One of its most important uses is in the ‘caesium clock’ (atomic clock). Microsemi Leadership in Atomic Clock Technology Quartz clocks also tend to vary more with temperature. atomic clocks, the cesium atomic clock has a special place, since the current unit of time is based on a microwave transition in the Cs atom. (Courtesy: Vector Atomic) Atoms are the world’s most precise timekeepers so much so that the second is defined as exactly 9 192 631 770 ticks of a caesium-based atomic clock. Atomic Clock is a precise clock with an electrical oscillator regulated by the natural vibration frequencies of an atomic system, such as a beam of cesium atoms, ammonia atoms, or rubidium.Ītomic clocks are inherently more accurate than quartz clocks, because their source of oscillation depends on atomic characteristics, while quartz clocks depend on the precision of the manufacturing process used to create the quartz crystal.
