I have one that has 6 gaps and a fan but it's a bitch to adjust it.

Hi Vinnie,

My cut on static spark gaps is based on a fixed voltage drop for each
gap surface (1) plus the drop (or loss) in the spark channel (2).

The first loss #1 would suggest having only one gap to keep the
number of copper-air interfaces down.  The down side to only having
one gap is it needs to handle the entire power loss.  Maybe the
answer to your question is use as few a number of gaps that you can
still keep cool.  Good air supply, large surface area, and reasonable
length pipe all help to spread the heat out.

Terry has built a SG with many many gaps where each gap is very
small.  I have tried his scheme and it worked very well.  In my case,
each gap was a little wider than Terry's so clogging of the gap was
less a problem. I switched to SRSG's before exploring the best
tradeoffs so I didn't try to minimize the number of gaps.

Gerry R.
