WOW, Is this a proven design? I have been in electronics for 40 years and
just never got around to building a coil. After my initial investment, I
want to make sure that this works the first time with minimal additional
expenses. Any Ideas on where to get the Tungsten for the RSG?
Oh yea , I LIKE MY LITTLE PIG!!!

Use a height to dia ratio of 4.5:1. This fixes the length at 90 inch
winding length for a 20 to 24 inch dia coilform. Divide this length
by 1,400 turns to get the wire OD --- determines wire gauge. Use
silver-tinned stranded wire with 1 kV PVC insulation. It should work
out around 18 AWG at this power level. Torroid should be 52 inch dia
x 16 inch cross section ---
can be made with metal mesh. Contact me off-list for construction photos.
If you are going high power you must use a large dia sec coil form to
extract the most performance possible --- why waste the energy? V
= -L Di/dT so to maximize L (inductance) it goes up as square of the
coilform radius and also the square of the number of turns, ie, L =
r^2* n^2 / 9a + 10b.
16 inch dia x 10 electrode RSG running at 3450 RPM or close to that
--- fast quenching. Need current limiting at 70 pri Amps to pump
15.5 kVA into the system. Primary cap = 0.2 uF 50 kV pulse duty rated.
