You can NOT use the 14 inch spark discharge to calculate the potential ---
this is the long streamer formed after your plasma has "grown" to a
great distance. With the coil you have described your true output
is around 150 max!!! If you single shot pulse it you will find your
true spark length. Then this value can be multiplied x 26.5 kV/cm to
get the correct output potential.
I know everyone likes to tell their friends they have a 1/2 million
volt coil, but it just isn't right. Our large Big Bruiser coil puts
out an awesome 28 ft long spark running at 26 kVA and yet the true
output voltage is only 833 kV --- it doesn't even break the 1
million volt level!!
