Exploding Wires, by Stephen P. Hansen
Steve Hansen, who runs the lovely site the Bell Jar about vacuum technology, recently put up a pamphlet he wrote called "Exploding Wires". It was formerly available through Lindsay Publications, now a free PDF download.
It's only 11 pages, but it's a very good start for someone who's never done any HV work before; it's very practical. It pushes off the HV power supply
issue to the ARRL Handbook, but is otherwise fairly complete in terms of constructing a first test apparatus and putting metal marks on a medium. The
author is fond of the blues and greens from copper wire. There's a nice diagram for a drop relay built of hardware-store parts; this is a way of
discharging the capacitor remotely. There's also a rather interesting set-up for doing explosive forming by detonating a wire under water; no chemical
boost required.
Consider this a learning primer, rather than any kind of authoritative source.

I used to get Steve's Bell Jar news letter. It was great. I also posted about exploding wires on my MySpace page. It makes lots of noise.
I'm the one who wrote the X-ray project at http://www.belljar.net/xray.htm
Lol, I still glow in the dark!

It's a good article. One thing I didn't really get until recently is
that the Crookes tube is actually Victorian-era technology. So for that hipster who really wants that steampunk frisson, an X-ray gun is just the
thing. But they'll have to find or fabricate their own tube; no fair repurposing later tube technology as you outline.

Hazard to Other Members, due to repeated speculation and posting of untested highly dangerous procedures!

The interesting thing with exploding wires is that the localized explosion can potentially be more powerful than a chemical explosion.
Wire explosions have even been successful at initiating fusion:

I would like to have one of these Marx generators:

(starting at only 8500 USD!)

I have made several Marx Generators and Cockcroft Walton Generators and the CW design is more robust (IMO). Below is an Excel spreadsheet for working
out your needs (on either actually).
This is the standard CW schematic for the single doubler: expanding this to several lengths will get some serious energy.

Here are other examples where a doubler is made into a quad. The importance of quality materials cannot be overstressed.
