Adtran today launched the latest additions to its Oscilloquartz optical cesium portfolio, expanding access to precision ...

The new clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say.

Unless, of course, you work at CERN and built “the most accurate pendulum clock ... With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one ...

These optical clocks are still being assessed, but already now, some are 100 times more accurate than cesium clocks. They will therefore become the future basis for the worldwide definition of the ...

But cesium clocks are no longer the most accurate clocks available. In the past five years the world’s most advanced atomic clocks have reached a critical milestone by taking measurements that ...

Cesium fountain clocks such as NIST-F4 are a type of atomic ... This month, the NIST team reported that NIST-F4's frequency measurements were accurate to within 2.2 parts in 10 to the 16th ...

A new atomic clock at the National Institute of Standards and Technology in Boulder is helping researchers count seconds to ...

caesium clocks Right now, the world defines one second ... Only results from well-prepared crystals are kept to ensure accuracy. This method not only boosts performance but makes the clock scalable.

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these ...

Each time the pulse rate could be compared with an accurate timing device on earth. Match with Cesium. If earth time does indeed slow down relative to the pulsar clock in January, and speed up ...

That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second. These optical clocks are still in the testing phase, but some of them are ...
