[TCML] 8 inch tesla coil design

[jeremyee@xxxxxxxx]

Hey group. It has been a long time since I have been on here and I wanted to pass a design by you guys to see if I have anything weird. Below are some inputs to and outputs from TeslaMap:

15 kV, 120 mA NST bank 
30 nF MMC 
8.625 inch secondary with 1160 turns of #23 magnet wire (74 mH) 
6 in by 30 in toroid (31.6 pF) 
Tuned primary at 14 turns for 112 uH 
Resonant at 87 kHz 

One of my main concerns is sizing the toroid for maximum breakout voltage but keeping the number of primary turns down to minimize resistive losses. At 14 turns I feel like I am a little too high. I am using a static gap with about 6 parallel copper couplings. My secondary aspect ratio is about 3.5:1 (is this ok?). I really appreciate any insight into my design. Thanks!
