I don't recall for certain if it was NeonJohn or another guy, or even what group it was in. Could've been the old geigercounterenthusiasts group on yahoo. This was some time ago, when we were laughing about the insane overreaction to breakage of CFLs in school classrooms. I've never tried opening a tube in a controlled fashion myself, but have seen tiny droplets in broken ones, usually near the ends of the tube.
Been playing with glass laser tubes a little the last week. Found that Gammex patient positioners used both red and green HeNe before diodes took over. Got one that won't lase though the plasma tube is a nice bright pink. It hisses or buzzes continuously but no beam output. The PS is good as it lit up a couple of similar size d tubes last night when I tried. I need to completely remove it and try sighting through the bore. It's possible it's leaking and coming up in pressure slowly and is now dead. I was looking at the metal evac/fill tube where it's crimped off and wondering about the possibilities of re-gassing... I have a couple of those metal tube ends with some defunct old tubes I got from Laser Sam a couple years back for experimenting. More interests, less time...
