atomic clock, electric or electronic timekeeping device that is controlled by atomic or molecular oscillations. A timekeeping device must contain or be connected to some apparatus that oscillates at a uniform rate to control the rate of movement of its hands or the rate of change of its digits. Mechanical clocks and watches use oscillating balance ...

Atomic clocks based on alkali atoms can be divided into four main categories. Fountain clocks (Clairon et al., 1991; Kasevich et al., 1989; Zacharias, 1953), the most accurate atomic clocks at present, are large devices that often take up the better part of an entire room and require several hundred watts of power.There exist perhaps 10 such instruments worldwide and each typically takes ...

2018-8-22 25 thoughts on “ Synchronizing “atomic” clock’s final tock? Time may no longer be synchronous ” . Kit June 25, 2020 at 2:32 pm. Even though NIST WWVB is still alive and transmitting, it’s a failed tech for me. The signal is so weak that the only chance I have of getting my clock to synch up is to place it on the sill of an open window facing toward Ft. Collins, which is nowhere ...

Laboratory optical atomic clocks achieve remarkable accuracy (now counted to 18 digits or more), opening possibilities for exploring fundamental physics and enabling new measurements. However, their size and the use of bulk components prevent them from being more widely adopted in applications that require precision timing. By leveraging silicon-chip photonics for integration and to reduce ...
