Capacitor bank trigger challenge

[digh]

Did Chris Hagen of National Securities Technologies, Tallboy DPF Las Vegas, have these problems with switches? For that matter did the DPF F-1000 in Warsaw? Rezwan had mentioned collaboration among the various DPF groups, Chris Hagen especially. Great idea. Any useful feedback?

and you do! the one spark gap in the middle is the DPF device, itself.
seems we want the rise time for 0 to 30 kV to be ~ 10 ns; and to hold at ~ 1.25 MA for 1 µs.

To combat inductance in the LPP’s setup, it would be useful to know where the stray magnetic fields are found during a shot.

Repeatable timing is imperative. I would design my own spark gaps tubes with high intensity UV LEDs (or lasers) to trigger ionization. This way the system could trigger upon demand.

I seem to recall seeing some comment about the switches you don’t like are the ones you’ve tried so far. No matter which they were.
