Spark Gaps and other means of switching
« on: November 29, 2007, 04:59:48 PM »
I'm hoping that people that have experiences with spark gaps and other means of switching suitable for Tesla-type devices will share there knowledge here:

The Theory and Design of the Triggered Spark Gap - T.J. Williams - the classic design guide for triggered gaps

Attached is "A Comparison of High Voltage Switches"

Eric Dollard mentions a "multiplicative" effect with spark gaps:

Quote
The action of the spark gap has a multiplicative effect also.  Consider Steinmetz' analysis: "Continual or cummulative oscillations involve an energy supply to the system.  If the energy supply is less than energy dissipation the OSC damps as a transient with reduced u.  If the supply equals the dissipation the OSC is continuous.  If the supply is greater the OSC is cumulative.
He mentions in another paragraph that he only encountered the "jamming together of electrons" when using spark gaps as the rate of rise of EMF is much greater by the spark method and he adds that strong impulses to not seem possible by "shunt" methods.  Then he goes of into plasma effects and other stuff.  Fascinating actually.
