The National Institute of Standards and Technology has set a new world record for the most accurate aluminum ion-based ...

However, aluminum is tricky. The element is difficult to measure with lasers, as well as cool to absolute zero. But when ...

Jacobson/NIST After two decades of tinkering, scientists at NIST have unveiled the world’s most accurate atomic clock, a ...

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 ...

A special kind of clock. Cesium fountain clocks such as NIST-F4 are a type of atomic clock—a complex, high-precision device that extracts timing pulses from atoms.

The Golden Standard of Timekeeping. NIST-F4 is a cesium fountain clock, which is considered the cream of the crop - there are fewer than 20 of its kind operating in the entire world.

Adtran today launched the latest additions to its Oscilloquartz optical cesium portfolio, expanding access to precision timing across a wider range of network environments. The new OSA 3200 SP and ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

Optical atomic clock achieves record accuracy redefining the second. 21 Jan 2025. Germany’s PTB develops clock that “ticks” at laser frequency 100,000x faster than microwave cesium clocks. ... an ...
