Re: Primary Q's and Spark Gaps

You wrote: 

The quenching action from a multi-section gap as you describe comes 
from the many plasma-to-metal interfaces.  The more metal that can be 
introduced into the gap, the better.  As is written somewhere in _High 
Power Electronics_ (I think), spark quenching action can ONLY take 
place at these interfaces.  Essentially, the metal is sinking the heat 
out of the spark, and the more surfaces that are interposed, the better 
job it can do.
