So you just need a bigger jar.

Switching and discharge within a few 10s of ns? I doooonn’t thang sew! :grrr: :bug:

that depends on the size of the wire. if 50 ns is the needed rise time (= 1/2 wave, ie: 10MHz), and you can tolerate a .006 ohm resistance, the skin effect limits the wire dimensions (in copper, ρ = R·Area / length = 1.68×10^−8 Ω·m; skin depth= 20.5 μm @10MHz) to a length no more than 7.2 x the circumference.

“The effect was first described in a paper by Horace Lamb in 1883 for the case of spherical conductors, and was generalised to conductors of any shape by Oliver Heaviside in 1885.”
