I see it like this as illustrated on the snapshot of the current trace below:

The slope of the green line represents the initial inductance lasting apx. 3 divisions.
The slope of the red line represents the saturation inductance
The blue line at the bottom represents the V/R limit (you call it "the capacity of the wires").

Right.  Now my other argument is that on the small toroid (why is toroid a spell-check error), the length of leading slope(green) may be so short that it's missed.

Maybe because the small toroid saturates so early that you cannot observe its "green line" ....or maybe the core has such small permeability and such high saturation point that it never saturates making the steep "green line" appear as if it was the "red line".

It is also possible that you have flux leakage just like shown here.

P.S.
"Toroid" is not a misspelled word.
This board has some issues with the spell-checker - see here.

@all,

While waiting on some parts like MOSFET drivers, i hooked up a KT926A transistor together with 2x 1N5408 DSRD's etc. to check if i can find any trace of the 1Kv/1ns pulse we need.
Max. pulse seen was about 130V :-(
Guess I will need some more sweeping of the repetition frequency (now 15Khz) and varying the pulse width.

Looks like the KT926A transistor is not fully saturating.
When a BJT is fully saturated, the voltage measured across its emitter and collector should be close to zero (almost a short circuit).

Also, remember that you can avoid the emotional stress and electronic hazards caused by the pulse width suddenly jumping up from the ns to μs scales, by altering your monostable multivibrator (made with U3), to the one shown here.

Hi everybody. It took me some time to figure out that the website had moved.
@itsu
I used your idea of a trimpot in series with the 100ohm resistor in the monostable, but instead of 10k, I used 1k. It works pretty well from 150 ns up to 1.5 us, with no jumps. I have sharp pulses at the 1N5408, but amplitude is about 120 to 150 volts. I have a limitation, which is the 40 MHz response of my oscilloscope, so it is possible that the amplitude is much bigger, but I'm not able to measure it. Suggestions?Verpies?
