Thanx
So the area also helps reduce the resistance of the gap.  So guess there
is another advantage than just cooling.

Can I ask what is a strip capacitor?
Just curious.

Luke: Yes the large area has two advantages; The total resistance of a
large
area gap greatly reduces gap resistance. When mounted vertical the gap
is
self cooling. When the small space of the series gap fires the total gap
spacing drops to minimum by the ion cloud conduction within the large
pipe
area dropping the total capacitor charge to a low voltage delivering a
large
ammount of total capacitor discharge power to the primary coil.  In
contrast
the safety gap dampens over voltage but dose not discharge the capacitor
charge acting like a voltage limitor not a spark gap. The same basic
service
but totaly different results.
             I use plate discharge spark gap discharge in my gas lasers.
The
large space involved produces another action not noticed on small spark
gaps. That is a traveling wave action. I start  the discharge at one end
of
the laser and the arc travels the length of the tube with the light to
compound the intensity at the output end of the laser. THIS DELAY LINE
TRAVELING WAVE IS NOT SEEN ON TC SPARK GAPS, Because they are not 1
meter
long and the capacitors are not strip line capacitors.
