Rubidium actually has a deep red colour to it, it was found using the 
flaming new flame spectroscopy method and is named so from the ruby-red 
colour it has. So you have a combined spectrum of the Argon and rubidium 
to get that colour.

Oh, and it's a 36 mm wide optical path in there... complete with a 
copper reflector for the lamp. Ah well.

This is a better start:

Is your atomic clock slow? Does it grind a little and needs lubrication? 
Does it run out of atoms? Then it's time to go to the atomic clock 
watchmaker and get it checked against a frequency standard.

There is also a bad pub in the second picture-text. "Oh, and I actually 
don't know of any clock which isn't built with atoms"

Jörgen Stedje was really enjoying himself. He read up on the LPRO 101 
and I added bits and pieces. When doing the review of the article, it 
was really just minor details and corrections, some rephrasing to get 
the technical details into decent shape. It's indeed a good article.

Not that there isn't caesiums in that lab, but we decided to concentrate 
it to rubidiums just to get one aspect clear, but still touching on the 
advanced stuff.

Probably not too much. There might be some IPR issues involved, but I 
can ask. I think Jörgen would love the extra attention. :)

He has written many good articles, including one about the Aricebo 
laboratory. As always many good photos.

Cheers,
Magnus
