Regarding my Cockroft-Walton multiplier which I plan for a CW type tesla
coil and marx generator circuit:

 >From the responses, there were some concerns regarding the use of a standard
NST connected to a C-W multiplier because of its
center-tapped ground terminal.

What is the best way to implement an NST into a C-W multiplier.  I think KEN
mentioned to have two C-W multiplier arrays on either side of the
center-tapped ground, but I think this would lead to a configuration that
has a floating output.  I would ideally want to have my marx generator
referenced to earth-ground.

Also, what types of values were you guys typically use for capacitors for
your big cap charging circuits.
I'm currently looking at some TDK 1000pF, 40kV capacitors, and based on my
charge current, I'll still get about 400-500V
ripple at the marx generator capacitors during charging.  I could reduce
charge current, but that would increase charge time which may or may not be
desirable.
