AFAIK most use a Ne/N mixture these days. I am not sure whether
I have seen He used as buffer gas for Rb cells, but I do not think so.
Other noble gases (Ar, Xe, ...) popped up a few times, though.

Hi
Aging in the short term tends to be dominated by equilibrium issues. Some of
them can have “many months” sort of time constants . That makes any study like
this pretty hard to do.
Worst case is when a short term effect has the opposite sign from the long
term. You go through a really flat
Hello Time-Nuts,
For the past several months I have been investigating the change in
aging rate of a rubidium oscillator with change in pressure. This has
been done with an operating oscillator in a temperature controlled
vacuum chamber.
Obviously, the frequency changes (a lot) with pressure
