Dr Jacinda Ginges, from UQ’s School of Mathematics and Physics, said the unusual atom – made up of an ordinary caesium atom and an elementary particle called a muon – may prove essential in ...

Caesium is having a moment, after being featured in the news recently, as the element in the radioactive capsule that went missing, and was subsequently found, in Western Australia’s outback.

Offering performance that far exceeds best-in-class magnetic cesium devices, the OSA 3300-HP is the industry’s first commercial high-performance optical cesium atomic clock.

The atomic clock used in modern timekeeping uses lasers to manipulate atoms of cesium-133 along a frigid shaft. Then microwaves blast into a huddled bundle of these atoms, and triggers their ...
