        Ahh, I see what you're saying Morgon.  I'm still curious about
something though (maybe this is a real dumb question, but I'm not
seeing it): why not process the electrodes before heating up the unit in
the oven?  Sure, the emitter coating will burn off and the resulting
particles will leave the emitter and then grab on to the inside surface
of the tube somewhere.  Will they not ultimately be released when the
unit is heated in the oven, and everything is then fine?  It would seem
to me this would have to work, otherwise normal electrical bombarding
would suffer from the coating particles adhering to the inside of
the tube when the electrodes are heated up (because the rest of the
glass is still at approx. 500F degrees, where it would be in the oven).

        If this would work, it seems a lot easier to me: process the
electrodes with the induction heater, *then* oven-pump the unit.  Now the
only thing that has to get into the oven is the tubulation connected
to the pumping manifold.

        What am I missing?

        Thanks!
