The heart of NIST's next-generation miniature atomic clock -- ticking at high "optical" frequencies-- is this vapor cell on a chip, shown next to a coffee bean for scale. Conventional vapor cell atomic clocks are about the size of a deck of cards, consume about 10 W of electrical power and cost about $3,000.
As for price, an atomic clock worthy of space travel could cost around a few million dollars, according Gramling, with crystal oscillators coming in substantially cheaper. But, Patla said, you get ...
Atomic clocks can also be isolated from environmental effects to a much higher degree. Atomic clocks have the benefit that atoms are universal, which means that the oscillation frequency is also universal. This is different from quartz and mechanical time measurement devices that do not have a universal frequency.
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
An antiques dealer offered the couple $6,500 for the clock, but they decided not to sell it. The man was obviously glad he waited to sell, and he was clearly shocked by how much the clock's value ...
The expected performance of a single-ion nuclear clock was further investigated in 2012 by Corey Campbell et al. with the result that a systematic frequency uncertainty (accuracy) of the clock of 1.5 × 10 −19 could be achieved, which would be by about an order of magnitude better than the accuracy achieved by the best optical atomic clocks ...
La Crosse Technology introduced the radio-controlled clock, commonly (but incorrectly) called an "atomic clock" after the extremely accurate timepiece behind the radio signal it uses as a reference, into the United States commercial market in 1991. [3] [4] In 2004, the company was awarded a license to sell The Weather Channel branded weather ...
The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight - the theoretical point of annihilation. That is one second closer than it was set last year.
