Thanks all for you opinions. I had never considered hydrogen or ammonia masers as a do-it-yourself project. Seems like this could keep me busy for quite a while!

I don't know about hydrogen or amonia MASERs, but there was an article in the "Amateur Scientist" part of "Scientific America" once about how to make your own CO2 LASER. I know it used a fire extinguisher for the source of CO2!! Given CO2 LASERs are powerful and invisable (wavelength = 10.7um), I doubt that sort of thing would be published today for amateurs to do!!
The MASER was in fact invented before the LASER and I have some reconllection it was an amonia MASER, but I may be wrong on that. Need to leave in 5 mins to get a train, so no time to check the web.
From reading what others have said, I can't help feeling trying to make your own Rb or Cs source is a bit of a waste of time really, but then one could say the same about doing jigsaw puzzles, only to put htem back in the box, yet my Dad loves doing them!!
