What is a Marx bank configuration (MBC)?

Over the years a Marx bank configuration (MBC), shown in Fig. 1a, has been used for generating high voltage fast rising pulses , , . Its advantage in comparison to some other methods, e.g. Krytons, is the short delay time and small jitter. The energy storage capacitors in a MBC are charged in parallel and discharged in series.

Can a Marx generator produce a higher voltage?

Recent Marx generator technologies have been able to produce higher voltages with a faster rise time than conventional capacitor banks, however, the high voltages and currents present in the latest stages (peaking/steepening switches) of the generators result in short switch lifetimes 23.

Why are impedance-matched Marx generators the next-generation pulsed-power drivers?

Impedance-matched Marx generators are the next-generation pulsed-power drivers because of their long lifetime (> 10,000 shots), repeatability (> 0.1-Hz), fast rise time (~ 100-ns), and high energy delivery efficiency (~ 90%).

Do Marx generators have a pulse forming line?

To achieve even faster rise times using Marx generators, they need to be equipped with a pulse forming line (PFL) like the Z pulsed-power facility at Sandia National Laboratories (SNL) 24.

How many stages are in a Marx bank circuit?

The Marx bank circuit comprises 17 stages, each stage comprising a single 2N5551 transistor. It has been found that a MBC does not work with a larger load resistance RL ; this can be explained from the slow charging of the junctions, resulting in their primary mode of breakdown only.

Where is a Marx generator triggered?

Conventional Marx generators are triggered from the stages furthest from the load, whereas TITAN is triggered from the stages closest to the load (we have called those stages-1, 2, and 3 in our design). The maximum voltage present in the module appears in the closest stages to the load where the external triggering system is connected.
