I am reading with interest your comments, but I notice a possible
problem: Q only affects significantly the output of a CW coil. A
capacitor-discharge coil has its output voltage fundamentally
limited by the energy stored in the primary capacitor at each
operation cycle. The output voltage cannot exceed:
Vomax=Vin*sqrt(C1/C2)
where C1 is the primary capacitance and C2 the total secondary
capacitance, what includes the secondary self-capacitance and
the terminal capacitance (a bit smaller that the sum of both, as
separately measured or calculated). Higher Q is certainly good,
however, because losses in the coil will be smaller. The limit
value is only reached in a lossless Tesla transformer.
