Just some food for thought. The safety gaps on my neons when using the
srg are set to about .25". The total gap length in the rotary is about
.12" for 2 gaps, .24" for 4 gaps, and .48" for 8 gaps. The 2 gap system
gives the best performance as previously outlined. I am definitely seeing
resonance charging since the meter directly across the neon secondary can
get to 20kv+ but the safety gaps do not fire when the cap matches the
neon and the primary is tuned accordingly and the terminal capacitance on
the secondary is large enough.
I am setting up a second srg which will run in parallel with a the
first gap. By adjusting the firing point of each srg separately I will be
able to cause 2 firings per half cycle and I will be able to adjust
exactly when each firing will occur. This may help to show if 2 firings
per cycle will process more power. If it works, it will bw a simple
matter to implement the extra contacts on a single rotor. I would still
like a mathmatical solution to this problem.
