In fact, this might be a good application for using inductors as the
charging impedance in the Marx. You'd choose the impedance low enough so
that the caps can charge in the required time between breaks, but high
enough that it doesn't damp out the 100 kHz oscillation from the TC.  

I assume that you calculate the primary tank capacitance as the bank's
erected capacitance (i.e. Cstage/Nstage)
