Hi,
I have published another measurement, this time of streamer current impulses
of very high amplitude:
http://sthlmteslacoil.se/measurements.html
I have also added some wild speculations, please feel free to comment.
not so wild.. I suspect that if you look at the capacitance of your
topload, and the inductance of the streamer (use 1 uH/meter), plus the
ground return to the coil (so, maybe 4x streamer length) you may find
you're in the right place for a resonance.
You could *test* this by putting a wire in place of the streamer, and
then driving the coil with a short impulse from a signal generator (or
any sort of oscillator) and looking at the waveform. You might also try
shorting the secondary from top to bottom for this test.
