To test my proposed ion hypothesis, run the coil in a vacuum. (nothing
to ionize!) I am positive the spark length of all coils would drop by
80-90%. This experiment can't be done on a large scale, but seems an
obvious and conclusive test to anyone who has studied electrical
discharges.

Be prepared for no sparks being recorded at 1/1000 second! With 360
breaks per second, the chances of obtaining any sort of image is only 1
in 3. Still those images which are captured might prove very
interesting. Problem- On an image, what period of the discharge are we
observing? Without some sort of sync in the exposure, tied to the gap or
discharge phenomena, we would still be quessing at what is going on.
