Surface Studies of Electrodes Used in Spark Gaps
Abstract
Protrusions on the surfaces of electrodes used in high voltage spark gaps lead to local field enhancements, which lower the self-breakdown voltage of the spark gap. Stainless steel, brass, and copper-tungsten electrodes have been tested in a 5-30 kV, 4-25 kA, .1- .6 Caul/shot, unipolar, pulsed spark gap with N2 gas or air. The heights and bases of variously shaped protrusions on the surfaces of these electrodes have been measured using stereo pair micrographs from a Scanning Electron Microscope.
