Modular High Voltage Pulse Generators

FAST RISETIME, LONG LIFE

The Mini Marx™ generators provide fast risetime and exponentially decaying pulses. The generators are housed in a compact, moveable, aluminum tank and constructed in standardized modular stages designed to provide lifetimes in excess of 100,000 shots.

VARIABLE PULSE AMPLITUDE

Pulse characteristics include a continuously variable pulse amplitude over a 3:1 range. This is accomplished by controlling the charging voltage and tank pressure. Pulse width depends on capacity and load. For a four-stage Mini Marx™ with four capacitors per stage and a 50 ohm load the pulse width is approximately 100nsec.

MANY APPLICATIONS

Typical applications of these Mini Marx™ generators are as trigger generators for high voltage pulse power systems, as laser drivers, and for many other applications requiring a compact and reliable source of high voltage pulses.

REPETITIVE MODE

With minor modifications, the Mini Marx™ generators can operate in a repetitive mode with frequencies up to several pulses per second.
