Marx Generator - Theory, construction, and operation of a Marx generator. How to build one and how to make real big sparks with it. - http://members.tm.net/lapointe/MarxMain.html
Pulsed Power Marx Generators - A marx generator is described as a device which uses a network of resistors, capacitors, and spark gaps to produce a brief, ultra-high power electrical impulse. - http://home.earthlink.net/~jimlux/hv/marx.htm
Marx Generator and Febetron - A Marx Generator produces a short, but very high voltage pulse by charging a stack of capacitors in parallel to a lower voltage and then switching them in series. The switching is usually done by spark gaps. - http://www.ee.ualberta.ca/~schmaus/elect/ftron.html
