Cockcroft-Walton Multiplier

I'm building a voltage tripler to charge a capacitor bank (20,000uf 450V)
I see halfwave series and halfwave parallel multipliers. Are these both
called Cockcroft-Walton multipliers or is it just the series type?

On this page; http://home.earthlink.net/~jimlux/hv/cw1.htm it says.

"The output V/I characteristic is roughly hyperbolic, so it serves well for
charging capacitor banks to high voltages at roughly constant charging
power."

The page shows a series multiplier, does that line apply to parallel
multipliers to?

Should I build a series or parallel multiplier? My caps can handle the
voltage
of the parallel.

I'll be charging from 120vac, 20 amp outlet. I want to charge as fast as
reasonable, I have 110 amp diodes so no concern there. But how do I size my
multiplier caps? I have 20uf, 40 uf and 1800uf caps on hand.
I suspect I'll want a series resistor to limit the current, but, do I want
it at the
ac input or between the tripler and the capacitor bank?
Thanks, Mike
