I guess you could do that if you only can oriented it there. However, I 
just wanted to play a bit safe and not overheat it... and then I did 
warm it up quite a bit anyway. Contaminating my lab with rubidium and 
glas splitter seems easier to handle than the oven and kitchen... but I 
don't think it is much of a danger anyway...

Well, a heat gun isn't a huge investment but it came in handy for this. 
If you seem the same thing, then try it and see if you get it operating 
again. I did actually learn this trick from a description for a smaller 
rubidium than I tried it on.

Well, it did not escape from the glas ampule, so it is still safe there. 
Rubidium by itself doesn't need to be a lot in there to work, but Xeon 
might escape. However, temperature and trimming of the RF source should 
be checked first... before giving up on the lamp.

Well, I tough that someone would get inspired. Seems to have triggered 
two so far.
