Hi Terry and All,
                          Well about the magnet or foil covered non-magnet 
both deflecting the beam
I find that in the 2 ft by 6 ft tube with 6 foot discharge, when it is 
trying to do a ~6 inch wide arc I do not want near the wall of the tube, 
(usually under less vacuum), I place a couple of old ion pump strong 
magnets so the arc heads away from that wall and more to where I want it. 
As we are talking ~1100 volt ignite then ~185 volt maintain arc currents 
(at up to 10 amps) across the 6 feet arc path and there is a .75 inch 
Plexiglas tube wall, I know it's magnetic, as the magnets are outside at 
room pressure and the arc, with electrodes are on the vacuum side of the 
system.
Even if you run the thing down to ~500 microamps with just striations and 
very small post ignite voltages, you can push with ~6 to 8 inches away, 
these displays with the magnet. Just like a computer speaker magnet neat 
the monitor or electric pencil sharpener near the monitor, stray magnetic 
fields deflect the electrons.
It would be interesting to have an electromagnet of the bar type for a more 
open field out further into the streamers and have that electromagnet 
pulsed at the same frequency as the RF in your system (if you could get the 
L and C of the magnet to work into that range) and see the frequency 
synchronized pulsed magnetic fields' effects.
As you are using a solid state (I think) pulse keying circuit in the driver 
you could grab the sync pulse timing signal from there, opto-isolate it 
then drive a DC device and supply for that Electro magnet. Could have cool 
effects.
Keeping the high voltage arc off the RF pulsed electromagnet could be done 
by placing the magnet inside a 5 gallon plastic bucket and hanging it over 
the coil. You could even phase shift the field to rotate it exactly where 
you get best effect.
Mike
