Seems to me, for a high-Q secondary you have Fr>>F-ringup (underdamped)
If the ring-up frequency = Fr, you have a criticaly damped pulse
transformer, right?

You mean two loose coupled resonators, K around .1? A detailed analysis is in
"A high potential Tesla coil impulse generator for lecture demonstrations
and science exhibitions by Kenneth Skelden, Alastair Grant and Slan Scott,
in that great little American Journal of
Physics, 65 (8) August 1997, pages 744 to 754." recommended and graciously
offered by Winfield Hill (his tech's will fax you it, see his
sci.electronics.design post)
