The new clock is an upgrade of the existing 5071A, which has been a major component in international time systems for 30 years. It is a three-unit height (3U) 19-inch rackmount box, which can be ...

They release optical light, as opposed to the microwave light given out by cesium, effectively dividing the second into about 50,000 times as many “ticks” as a cesium clock can measure.

To do this, a high-powered laser light is trained on an atom of cesium-133, which subsequently excites its electrons into phasing between energy levels at exactly 9,192,631,770 vibrations over a ...

A common kind of atomic clock uses a form of cesium called cesium-133. In this case, microwave energy interacts with atoms belonging to a form of cesium called cesium-133.

The high level of accuracy has now also been demonstrated in a new type of clock that has the potential to measure time and frequency 1000 times more accurately than the caesium clocks that currently ...

The different types of states are separated, and the high energy atoms decay to the low state, emitting light of the same characteristic frequency, which for cesium-133 atoms is precisely ...

Atomic clocks are based on the fixed frequency of light absorbed or emitted from atoms which have precisely defined energy levels. The idea of using light frequencies to measure time was first ...
