In 2001, Japanese physicist Hidetoshi Katori proposed a new type of atomic clock that only loses a second every 30 billion years, a period longer than the current age of the universe. The ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

R esearchers have developed a new approach in optical atomic clocks that brings forth a major goal in science: the redefinition of a second. The fundamental unit of time could soon be based on ...

Microchip Technology has introduced its second-generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC), model SA65-LN. It features a lower profile height and operates in a wider temperature range, ...
