I'm wondering if it could be an issue of the trigger pulse adding the
needed energy to maintain the arc channel while it is firing? I realize
that the current isn't that high (maybe Terry or  Mark could put there
pearson on the trigger lead so that we would get an idea of the trigger
currents?) but the voltage is higher then the tank voltages, Since
voltage is "the speed of the river" the electrons of the triggered pulse
would move faster then the tank voltages. I'm wondering if it could be
that while the tanks energy is oscillating back and forth, the triggered
pulse is holding a path open so that it doesn't have to reform an arc
path to travel?
I've seen that adjusting the dimmer not only moves the pulse point down
the sine wave, But also changes the "time" that the trigger pulse is on.
Also when my dc pwm circuit was running, it liked longer pulse
duration's then short. I can't see any reason why this would effect the
output, Because we would assume that once the arc channel in the gap is
produced it should maintain itself until enough energy drains from the
tank to shut it off? But what we actually see is that for some reason
the efficiency is brought up if the tank energy has a "path" to follow
that is pre made (or close to pre made)?
Would it be possible to rectify the 120 vac driver pulse coming from the
dimmer, Then use a transistor to turn each driver pulse into a higher
frequency pulse? I'm thinking that if the triggered pulse could be made
at a high frequency, Then the tanks arc path would have an even more
continuous path to follow?

I think it was around "6" or something like that?

I really want to test some gap spacing data, I think the stsg could be
made to fire on the second notch just by closing the spacing up a tad.
It is a very tight difference, but when the spacing\air flow is set so
that the tanks energy maintains a channel until the energy has passed
back and forth twice, it will then shut down on the second notch.
so if someone really wanted to try first, second, or third and more
notch quenching, it could be done by simply adjusting the gap.
