Abstract: We describe a new microwave synthesizer chain to produce the 9.192 GHz Cs frequency currently being developed in a cooperation of PTB and NPL India. In this synthesis a 9600 GHz YIG ...

Abstract: We report on measurements of frequency shifts in a high-performance microwave cesium vapor cell atomic clock based on coherent ... the future demonstration of a CPT-based cell clock with ...

This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location ...

The Mid-Century Modernist movement was more than an aesthetic or material shift in the United States, as it was a response to a rapidly changing world. Emerging after World War II, this ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use ...

BOULDER, Colo. — A new cesium fountain atomic clock at the National Institute of Standards and Technology (NIST) in Boulder is making time more accurate by fractions of a second. It took a team of ...

In 2011, two teams of scientists created an uproar after revealing they had separately mutated the H5N1 bird flu virus to spread among ferrets through the air, something it didn’t do naturally. The ...
