Hi,
I am at present fiddling around with several projects,
as i suspect many of you are too.
One of my projects wants a very brief sharp rise pulse,
achieved as minimally and easily as possible.
This wants the rising pulse to be as fast as i can make it.
I am considering a very simple circuit of a tiny air gap
across a small capacitor fed from a couple of meg-ohms to
about 100 v or so.
My question is about the speed of air breakdown, are
modern high frequency transistors faster than a tiny spark ?
I'm referring here to the rise time, not the repetition rate
that i may or may not achieve.
If transistors are faster, i will start on a different track
for this project.
Personally i would think that voltage breakdown of air
would be about as fast as it gets, but i don't really know.
Cheers, John
