19th Day of Christmas: Frequency Standard

This Advent during the 24 days leading up to Christmas I thought it would be fun to have a quick introduction of scientific apparatus, in particular tools used in atomic physics research. This is a way to say thanks to their hard work for our research, and a look at how many things are really needed to make a laboratory work!

Frequency Standard

Not all, but many atomic physics experiments involve¬†precision time. It might be to measure a frequency very precisely, or to synchronise the sense of time for multiple devices so they agree on what’s being measured. This is where the frequency standard comes in. Frequency standards are devices that provide a very stable frequency/time signal to other equipment. They contain some very stable oscillator inside, and they output a very precise standard reference frequency, most often a 10MHz or 5MHz signal.
