Dr.,
With all due respect: 18-24" DIAMETER secondary!?

You jest, of course.

Dan:

Usually you set up the pig for testing with a climbing arc on the output.
Then, if you set your current reactor to draw around 40 Amps on the primary
circuit you could match a .05 uF or .06 uF in the primary.

Run a asynchronous RSG at 1725 RPM with around 12 electrodes on a 16 in.
dia. G-10 disk (1/2 in thick).  This will give you a good start.  I would
suggest a sec coil of around 18-24 in. dia with an aspect ratio of 4.5:1.
Oscillator base height around 22 inch (pri elevated at 24 in above ground
level).
