Re: RQSG Cylindircal style question

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.

Hello All
In the process of upgrading my coil and I plan on upgrading or
building a new cylindrical style RQSG.
I've forgotten where I've placed the power specs. Does anyone know
how many segments and gap spacing I would need
for a 12,000v @90ma input with 8 series 942c20p15k? I'm upping from
my previous input of 12,000v @60ma.
Perhaps it's not advisable without a larger cap value?
Thanks for your time
Vinnie
