I've built several pulsers with gaps in oil, not primarily for quenching,
but they ran at PRFs (pulse rep freq) up to 1 kHz. They were all annular,
with oil pumped through the electrodes. When the arc jumps, it is in a gas
environment, so the electrode wear will probably be not too different from
air. I would stick to tungsten or Cu-W alloy, if possible. The arc will be
very short, so good machining will be needed to maintain good spacing.

Subject: [TCML] fluid quenched rotary spark gap
I'm planning to build a synchronous rotary spark gap with the terminals
inside a fluid tight plastic box and filled with dielectric oil. This
should cut down on the noise, allow me to use steel electrodes because
of the lower temperatures, and it should quench like a champ. Has anyone
had any experience building one of these?
