Xenon Arc Transients, Electrical and Optical

Abstract
The growth of the luminous area of a high current discharge in an electronic xenon-filled flashtube has been studied by means of a sequence of timed short-exposure photographs taken with a magneto-optic shutter. Electrical measurements show that the tube conductance is approximately proportional to the luminous area of the arc channel. The ionized gas has a volume conductivity of about 90 mho/cm averaged over the luminous path during the buildup for the conditions investigated.
