This is something I'm not very clear on.  Is there a difference between
a discharge and a plasma?  Inside the central electrode I imagine that
the electric potential is fairly flat but it's sitting at -20 to -50 kV
relative to the grounded chamber, throw in some low pressure gas and you
have a Crookes tube.  A lot of these guys test their set-ups with
nitrogen before they run with deuterium, do they still get the pretty
"star" with non-fusing gases?
