Lots of data on continuous arcs.
Lots of data on single shot discharges.
Lots of data on 60 Hz breakdown (but steady state)
Lots of data on gas breakdown with RF, but not from electrodes, rather, in
waveguides.

Almost no data on spark growth with a repetitive pulsed RF source.

Another good reference is Bazelyan and Raizer, "Spark Discharge", published
by CRC press.


However, as all those authors point out, spark growth, in a repetitive
system, "is not well understood".
