Thanks a lot! That was exactly what i was looking for.
It took me a while to read the paper
Moin,
For some time now, i'm wondering why the microwave cavity of Cs
beam standards is U shaped. Ie why does the Cs beam fly first
trough the first subcavity, leaves it, flies a substantial
length trough free space, passes the second subcavity and
then goes to the detector.
If the interaction

The tube is like an interferometer. Think of two telescopes
spaced apart x meters. It has the resolving power of an x
meter diameter telescope. It doesn't have the light gathering
power of an x meter telescope.
There is sufficient RF power to flip the state of all the Cs
atoms, so additional
