As I have only one capacitor available at the moment, I cannot
distinguish energy from voltage effect.

We are working on arranging $$$ for that. We are talking about >35000$
money. Last year I applied for four scholarships to buy a fast camera,
got none :(

I need to find a way to record (see) the streamer elongation. Need to
measure the current into the streamer.

Absolutely. Need for measurement as above.

Yes. At the moment I have very tight gap, resulting in quenching after
the fourth (!) notch.

No. Where?
