Re: [TCML] High Power Static Gaps

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.
The literature has references to gaps of this type (generally, not with the specific construction you describe) running at multiple kilowatt power levels. The Marx blast gap is a good example. It actually used air blowing out through the center hole in the electrode.
