Re: [TCML] High Power Static Gaps

[vgreat@xxxxxxx]

I my experience with single static gaps, it is not spark lenght that is diminished but RUN TIME.? The contact points foul so quickly. I have tried the vacuum cleaner aproach, used a Nitrogen gas purge, and used a massive air purge.. all to limited improvement.. The static gap that worked the best for me was the multiple parrellel copper pipe approach. I believe this was a Richard Quick design discussed on this forum in the late 90's.??

Hi All,
 
I'm curious about the spark lengths achieved by others using a single  static 
vacuum aspirated gap, (I believe the one designed by Gary Lau if memory  
serves)? It uses a vacuum cleaner motor, PVC pipe and two large copper tubing  
end 
caps with holes in the middle for the electrodes.
 
What are the limiting factors with this type of gap? Can it be scaled up  for 
higher power? It's a beautifully simple and elegant design, without the need  
for any close tolerance machine work like with rotaries, and it's much safer  
too.
