It is a short pulse of a few hundreds of ns. I had to put 100 Ohms of resistance to get the pulse down to 100 Amps so I can measure it. The spark is MUCH more intense (sounds like a gun being fired) without the resistance and just limited by stray inductance. The peak current with the resistance in the circuit is early what I would expect where the resistance dominates the circuit impedance. 1000 Amperes is an estimate as I have no easy way to measure it directly. Somewhere from 500 A and up.
The capacitor weighs about 30 lbs! By careful adjustment of the gap I can get it to become a relaxation oscillator. It sounds like a machine gun. My wife says I should keep it to a minimum lest the SWAT team shows up. My experiments have been known to adversely affect electronic gadgets, like my wristwatch and a camera. But if one really needs to know what a piece of equipment can take, this setup can do it. The pulse is far above what secondary lightning protectors can handle.

Not sure about the gain or directivity but that's alot of power! Hopefully it's just a pulse or two in the microsecond range. And hope you're in the desert. Very interesting indeed!

New content will only be posted to Odysee though. I am currently working on a new video using my home built EMP generator. Nothing like a 1000 Ampere, 15 kV high voltage pulse to spice up the day! I am also working on a Marx generator to get extremely high voltage pulses as well. If you don’t hear anymore from me, I may have been vaporized.

(I am at about 1500 miles of running in 2021 so far at age 74, much of it at 110 degrees F in the Southern Nevada desert this summer.) Each channel now has one video with lots coming soon. Some of the engineering videos are snippets from the demonstrations of my seminars, including the virtual ones coming up shortly.
