Interesting article, the home-brew triggered gap is especially neat. Marx
Generators have traditionally faired poorly against Tesla Coils in terms of raw
spark length, since their slow firing rates squelch the wonderful shot-to-shot
buildup that Tesla Coils enjoy. Replacing the sparkgaps and charging
resistors with solid-state switches however might allow the Marx Bank to be a
serious contender in the 'arc-length vs power' arena. Solid-state switching
would allow the Marx to run well up into the 100's of Hz, allowing exploitation
of the shot-to-shot buildup effect. Below is a link to some recent prototype
development work towards this end:

A 550kV[peak] coil [the 120L50K at Hunter's Point Naval Shipyard] can generate
about a 25' arc at 360 BPS. I'm keen to find out what a 500kV Marx Bank can do
at the same rep rate into a suitably elevated electrode. GL.

Hey y'all: In the current issue (July 2004) of Conformity magazine 'The
engineer's guide to worldwide regulatory compliance' there is a feature article
titled 'Build Your Own Marx Generator' by Mike Harrison of the
UK. It features three projects aptly named Marx1, Marx2 and (you get the idea).
