Re: 20 joules at 100 bps vs 4 joules at 500 bps - any difference?

Hi John,

Seems like one could attach a "side wart" to the toroid that had a larger ROC then the other side would be the breakout point (maybe a toroid whose major diameter instead of following a circular path would follow an eliptical path as looked upon from above). The wart would increase the capacitance and yet the original toroid would shield the wart from changing E Field in the direction of breakout. Maybe one could see then how much the extra capacitance contributes to streamer growth and how much the E field "reach" contributes. I'm bettting that both help but dont know for sure.

I suppose this may indeed be the reason why certain coils
don't benefit much from higher breakrates.  The toroid field may
be too small to support longer sparks as power is added via
higher breakrates.  What evidence is there that the field of
the coil itself rather than the toroid dia can limit the spark
length? (Ignoring coil breakdown issues.)
I remember there were some postings about this
a few weeks ago but I wasn't following it too closely.
