Hi,
  I was thinking the same thing but with a complex controller. The idea is 
that a short burst of high current (large value cap?--include diodes to 
attempt to stop ringing) is supplied to a electro-magnet every half cycle 
in order to "trigger the gap".This idea stems from a former post where 
breakdown voltages were given, showing a lower breakdown voltage with 
magnetic flux applied. Also, if is not to complex,  a current detecting 
device could be used to tell when the first notch is reached, triggering 
another magnetic pulse to quench the gap. To sum it up a sync trigger and a 
event(first notch) trigger for a single electro-magnet.
Feasible, with a lot of work or just random ramblings.
Cheers,
John

about making the main spark gap electrode holders into a coil of lets say
1/4" copper tube or 12 gauge to make the electro magnets to quench the
gap.Using the current that flows thru the gap itself to supply the flux
necessary for quenc hing.Seems to me that this could turn out to be a pretty
efficient set up.
