Just fooling around to ballpark things for a multi coil setup.

Secondary 12" in diameter, 48" winding, #20 wire, spacewound for about 750 
turns about 37-38 mH, 22 pF Cself
Topload, 8-12" tube, 48 diameter overall - about 52 pF

Fres(sec) = about 100 kHz

Primary, flat spiral, copper pipe, 6-8 turns, 48" OD, 20" ID (i.e. 4" 
clearance from sec bottom - about 50 uH

Cpri needs to be about 0.06 uF

Charged from DC source at 11-15 kV... here's the problem.. I'd like to be 
able to put around 5kW through the system, and with the fairly small cap, 
you can only store around 6 Joules/bang, and at 200 bang/sec, that's only 
1350 kW.

Ideas: Use resonant charging, so Vpri can be twice source voltage: say, 
20-25 kV, so Ebang = 12-18 J, => 2400-3750 kW

Could reduce Lpri, which would increase Cpri, and hence Ebang (for the same 
voltage)but it strikes me, as a gut feel thing, that going to 5-6 turns on 
the primary is pushing things.

Suggestions, comments?
