You may not be able to drive all that power at 2500V, certainly not easy with a doubler sagging down,
Do you really need to measure that fast?  If not, then the switching speed can be 80 or 60 or 50 kHz, and
maybe 6 of those needed to ramp up to near 2500V then settle accurately on a valued for measuring position
such as 2330V.  So overall response time would be about:  72 microseconds.  (13.8kHz rep rate.)

I also found this calculator: http://www.dicks-website.eu/coilcalculator/index.html

Yep, that's what I used.
