Yes, I know what you mean. I had a streamer get nasty with me last week
while adjusting the TSG gap to
"not" conduct without the trigger, when it shot a rather very strait
streamer 90 inches almost
perfectly horizontal stopping just in front of my face! That was enough of
that.

Have you tried the breakout points to protrude from the edge (center)?
Points of charge should build
around the edge.

I understand a lower bps allows more time to charge the cap to a higher
voltage, but I'm not sure how
this accounts for the gas burner effect. That in itself would be very
interesting to study. I wonder
what other conditions are present to cause such an effect. I've heard of
it, but never expereinced it.

Sounds good. Keep us posted.

Take care,
