Re: Fast quenching spark gaps - External Series Gap on Rotary Gap

If your electrodes pass through the rotor disk axially, then you can use the
opposite side of the RSG as a sparkgap as well.  This goes from 2 high speed
gaps to 4 high speed gaps.  We usually use around a 24 inch dia. disk for
magnifier design as the extra ft/sec really helps quenching by reducing the
electrode presence time considerably.
