Professional Equipment for Serious Research

This page describes our Marx generators

Very useful in the fields of high energy physics. Marx generators are simple in theory: a stack of capacitors are charged in a parallel configuration to a voltage "E" and then discharged in series with a voltage of "nE" where "n" is the number of capacitors charged. The discharge now has an equivalent energy equal to that of all the charged capacitors at a very high voltage. This discharge is very fast (into the nano second time period) providing the monstrous peak powers necessary for many physics, electronic, electrical, chemical and nuclear research projects. See our download for more information.

Marx Impulse Generators for Higher powered Professional Research

Available Systems from our Labs allow charging voltage from zero to full value with manual and +5 volt fire control. Systems are complete and require 115 or 230 vac for operation. Discharge shaping resistors are available per your requirement or use as is for fast discharge. Typical charging times/cycles is 4 to 7 events per minute with a rise time of 5 to 8ns and pulse duration of 50ns. System must not be in proximity to sensitive electronic equipment without suitable discharge shaping resistors.

Marx Generator

Available Systems From Our Labs

Below is a chart showing the models of Marx generators that are turn-key ready to use. The information should give a sufficient idea of the product capabilities. These designs may be modified at your request and you are welcome to submit variations that may fit your research project.

All systems allow charging voltage from zero to full value with manual and +5 volt fire control. Systems are complete and require 115 or 230 vac for operation. Discharge shaping resistors are available per your requirement, or use as-is for fast discharge.

Typical charging times/cycles is 4 to 20 events per minute with a rise time of < 100ns down to 3.5ns (with the proper setup) and pulse durations of < 600ns down to < 50ns. System must not be in proximity to electronic equipment without suitable discharge shaping resistors.

We offer downloads of setup and operational instructions for two of our items to give an idea of what is involved:

SuperMarx Generators for Serious Research

Intended for research labs studying lightning effects on aircraft and other sensitive equipment.


SuperMarx Generator

This is an example of a large SuperMarx generator, capable of simulating full-scale lightning strikes.

Nothing compares to an item being testing with full-sized, full-value inputs.

Computer models are great: they have the benefits of being inexpensive and allowing nearly unlimited simulations. But computer models also have limitations and aren't always correct, because they run code which is created by people, to calculate formulas, which are based on gathered data from a finite number of real-world experiments. So while computer models can give accurate simulations under previously-tested conditions, they can quickly lose accuracy in new situations or untested parameters.

Small-scale physical models have the advantage of being real-world and also less expensive than full-scale testing, but a scale model is different from the real thing, and the forces and results will behave differently. In short, models don't always scale up accurately.

To get real results of how things will actually happen, full-sized testing is the only way to go. There are no substitutes. And that's where a SuperMarx Generator comes in -- full size, with full results.

Custom installation is available, if needed. Please contact us with your requirements.
