I'm looking for a link to point to an explanation (at a basic level) of
the difference between Rb and Cs references, and what the tradeoffs are.
I googled a bit, but all I got were some explanations of the differences
in things like vapor pressure, etc.
What exactly are you looking for? A comparison of Rb vapor cell
standards vs Cs vapor cell standards? Or a general comparison
why different kind of standards are built with Rb and Cs?
For the former, there is a paper that has some of the details
why Cs was choosen over Rb for the CSAC in one of the papers.
(Which I currently cannot find...)
For the latter, there is no easy answer and a lot come from
technicalities (difference in handling) and what people were
able to build. There are some fundamental differences in which
elements get you what kind of stability for different kinds of
atomic clocks, but I have seen very little on that and it's quite
spread over various papers and books.
precisely why I asked..
The wikipedia article isn't bad in terms of covering the gas cell vs
beam in words, but I was hoping for something with pictures..
Encyclopedia Brittanica, perhaps.. except that they only talk about
caesium beam
