  Why the fuck would anyone with a heartbeat put sailors on a steel ship they were smacking with the largest emps they could muster at the time is beyond me.

I hear its the fastest direct rout to Norfolk...

Drift Step Recovery Diode (DSRD) - Its a very Russian thing to do...

Prof Alexei Kardo-Sysoev of Ioffe Physics Institute, St. Petersburg Russia

100 kV pulses, to rise times on the order of 1 ns

Read this about ten times:

1. Energy is stored in an inductor at low voltage, then the current is broken quickly by use of opening switch, such as a Drift Step Recovery Diode (DSRD). The current goes to the load forming a short pulse. The load voltage during the pulse is an order of magnitude higher than the initial voltage used to store energy in the inductor. Therefore the high voltage exists only during a very short (several nanoseconds) pulse length, and only in a very small portion of the circuit (output cable). This has obvious safety advantages, and the arcing problems are not so severe as for high voltage DC.

How fast of a rise is fast enough?

200ps?

200ns?

With 100kv, rise probably doesn't matter as you have so much potential. 1us is probably good at this voltage.

Of course it takes more than a fast pulse.  You need high impedence to the pulse, high surface area/mass, and then you have to catch it.

Well I would guess that it depends on the efficiency of the setup and what you want out. I need to quit thinking and get back to trying!

Seeing the way the TPU spools up I am beginning to think that it is a low power device but accumulating output over a number of revolutions before it is sent to load.. this is just a guess... Im guessing it is not over 3kv maybe even lower.

Im trying to finish a big project and then I am planning on locking myself in my lab at home for about a month. The questions are piling up.. Lab fridge is stocked up.. Pizza shop on speed dial.. Three phase humming eagerly...

Iv got a big 0-10kv Power Designs supply and a pair of freshly calibrated Wavetek 5ns pulse generators that just showed up so I can get more precise test points. I have a number of Mil spec. 5kv triodes sent in a care package from the motherland..

Maybe you will be cooking pizza with a new oven by the end of the year!

I got coils to wind...
