Thread: Plasma Tubes Big & Small

    Default Plasma Tubes Big & Small

    Here's a manly plasma tube, coming out of the '85 Plasma Kinetics model 451 copper vapor laser. The tube is 78" long with the center section being 6.5" diameter. The bore looks like 2" and the windows are 4" diameter. Only way I can get the covers off to hammer them back into place is to take the whole thing apart so I can move it around.

    For contrast, here are the smallest plasma tubes in the collection. Smallest is about 4" long, probably from a gun sight or other pointer.

    This is what I see when I look down the bore. The head was apparently dropped, as the water jacket is dimpled where it sat in the plexiglas cradles. I'll open it up later this week and clean it out. I wonder why that piece of metal is bent up into the beam path like that? Doesn't look like damage.
