Bert,
Just read this and must comment to seeing this one myself a year or two
ago. I think that the coil with each micro discharge is ringing up and
down. Just like you note in the form of a relaxation oscillator. The
time constant would have to do with the gas in the tube or the body
ground resistance (probably hundreds of megohms. The capacitance is
small and thus the relatively short time constant.
There are other senarios such as pre-charged air movement over the body
from the approach to the system, etc, etc. Who can figure all this stuff
out???!!!
