Hi
With a common Cockroft Walton mountage the last stages
will take lower input, because the capacitive
reactance is adding. A solution is increasing the
frequency but this will expand the costs of the
mountage.


You can try a simetrical configuration like this:

With a 15 kv NST the output voltage  (theoretical)
would be around 84.6 kv.
For 60 mA from the NST you can experiment with 1-10 nF
caps.
