Greg et.al. IEEE stuff is just too expensive for single purchase. I have
found, to my sorrow over 40 odd years, that they also do not contain
<real> information, that is, info of actual use, because some other
company or person might actually benefit. In other words, the papers are
markers in the sand.
Now, this is my own opinion, a bit harsh, admittedly. Of course the
citations do need to be mentioned.
BTW, any published material generated with government funds that is not
classified belongs to the people, and is not copyrighted. I wonder if
that includes IEEE papers? that is, if anyone buys one, it can be copied
or distributed without restriction?
Not being in the lawyer class, I can't say for sure...
Thanks

When I scan/read the 1984 IEEE document, “Lifetime and Reliability of
Rubidium Discharge Lamps for Use in Atomic Frequency Standards”
by Aerospace Corp., Efraton-Ball, and EG&G.
https://ieeexplore.ieee.org/document/1537723/
The failure of the rubidium lamps used on early NAVSTAR satellites,
was the reason for in-depth studies of the Rb lamp, its lifetime and
failure mechanism.

Hi -
I later tried that method on my R&S XSRM rubidium, with good progress.
I
have reported on that on the list way back. It took two attempts, one
just to realize that I needed to keep the pinch at the top, because
that
is where the hot atoms go.
Essentially, the thin film of rubidium will consume too much of the
radiation to emit any useful amount of pumping light. Heating it has
the
rubidium go into gas and then collect somewhere cold, so it's just
about
making sure that somewhere cold isn't the glass where it is to emit
light.
My XSRM have however other issues that I need to attend to.
Cheers,
Magnus
