You have to love those Cockroft-Walton voltage multipliers; no
single component has to withstand the entire output voltage.

Did you know about the trick of using larger capacitors (or same-size
capacitors in parallel) in the lower stages to reduce output ripple?

Yes, and I don't see where that is a trick. I thought that was common?

It probably is, but I have seen physics students build them from
the original 1951 paper by James D. Cockcroft and Ernest T. S.
Walton with equal value capacitors. I probably should look up the
original paper and see if it mentions larger capacitors near the
bottom of the stack.
