OK, I'll start asking specific (and ignorant) questions.

What are the important measurement parameter(s) of the spark? current,
I'd guess. others?

What is the optimal spark voltage range?

How do you measure? Standard shunt techniques? ...?

Is the spark long lived enough to measure directly?

What is the relationship of gap to spark current?

How do you tell between a short and a spark?

Is there a range of spark currents that allow one to adjust electrode
gap via PID or similar algorithm?

What effect on the spark does the electrode shape and/or material have.


By the way, a raster approach could be sped up by using multiple spark
electrodes. Might have to offset them a bit though I'm not sure about
that. Any reason why one should not use a bidirectional raster
approach (LR, RL, LR ...)
