Abstract :
The rapidity of a current "chop," occurring when a vacuum arc spontaneously extinguishes, is measured for a low current tungsten arc. The time required for cessation of the arc is found to be 2-5 ns. An estimate of chopping current verifies the notion that a minimal current is necessary for the existence of an arc.
