Hairpin Circuit: Strange Spark Gap Behavior

[mikrovolt]

Among the variety of discharges are the stinging rays.
The video shows the exploding wire experiment. (As a visual that is close to the other stinging rays)
Is there good reason to raises the question of just why they are special ?

One author writes about Tesla's experience with these rays.
He offers this document on why these Tesla rays are special.

SHOCKING DISCOVERY

Spark Gaps :: Radiant Effect

Is it repeatable? Can this be shown ? Is it a mystery or a fluke ?

Another very old spark gap. operates fairly quiet but has the popcorn sound, this erratic irregularity smooths as the resistance decreases
The (dielectric) vacuum also relates to the density of the spark. We can see a wider diffused stream when rarefied.
further vacuum would quiet the noise however there appeared the mysterious dark space.
There was seen plasma cup shaped with depression and the negative electrode eroded and fine
metal deposited on glass around it.

The comments below the video has information. A detailed schematic would however be useful.

Museum Geneve built an awesome replication of the De la Rive big egg vacuum tube.
This really helps to appreciate the oval shape and the precise use of electric magnet.
I like how the early science was about discovery more than making things and stuff.
Many characteristics can be studied with this latest replication.

Quick update

Just wanted to let you guys know that I continued to research and experiment with my Hairpin circuit, and have so far upgraded every single part of it:

- Switched to a 50Hz 15kV iron core NST, since the 34kHz version shorts the circuit due to its high frequency
- Upgraded from 10mm to 22mm copper bars, since Tesla said "the thicker the copper bar the better it is for the success of the experiments, as [the effects] appear more striking."
- Use lower impedance connections to minimize reflections due to impedance mismatches
- Increased capacitor size for better resonance
- Built an advanced Tesla air quenched spark gap replication

You can see the spark gap in action here with a 24mm gap distance:
