Re: Spark Gap Gasses Experiment
This is precisely the case. I gave a paper at ITS in 1992, on
spark gap technology, dealing with this very phenomenon.

Interesting. I wonder if perhaps the purpose of the airflow is to cool
the metallic faces to keep hot "cathode spots" from forming. Once a hot
spot would form, the breakdown voltage would be greatly reduced (just my
guess) since the hot spot would then be maintained via metallic arc
(since all the energy would continue to flow through that location).
This operation is opposed to the conventional wisdom that the air blast
interrupts the damped waveform (which, according to Terry's
measurements, is not the case)...
Comments anyone? Let the flaming (or arcing) begin! :)
