I looked... I wish they had part numbers in their catalogs that I could compare against the

>Warning #2 - I don't know what your background is, but a multistage high voltage Marx generator is an extremely ambitious undertaking. Triggering and erection can be capricious, and can depend hugely on the geometric distribution of the components. If you can find it, a book called "High Power Electronics" put out by Tab a few years ago discusses some of these problems. If you go for 600kV, the whole shebang will need to be in a tub of oil or else be spread out over a large area, with spheres, graded surfaces, etc.

I've decided to stick with something less ambitious -- 100-150kV. I'm planning to start it relatively low key and work up to a high-current unit. I'm thinking of working up from 10-20A peak current at 100 kV to 1-2 kA peak current at 150 kV, gaining experience and information as I go.
Thank you for the book recommendation; I am sure it will come in handy. I looked for it on Fatbrain, and they list it as out of print. Does anyone have any good ideas about where to get it, or any other good sources?
As for my background, I majored in Applied Physics.
