Electrode Erosion by Spark Discharges
British Journal of Applied Physics, 1950Theoretical estimates of the areas of electrode hot-spots are made from a consideration of the lateral spread of the electrons and positive ions due to diffusion and their space charge. Areas thus found show that very high current densities of the order 106 A/cm2 are possible in typical short spark gaps at atmospheric pressure.

Physical Review, 1940
The breakdown of a uniform field is considered to occur by the transition of an electron avalanche proceeding from cathode to anode into a self-propagating streamer, which develops from anode to cathode to form a conducting filament between the electrodes.

Thermalization of a spark discharge
Journal of Applied Physics, 1975A thermalization process that depends on both localized and channelized Ohmic heating of a plasma in a spark discharge is proposed. A satisfactory quantitative description of a spark current pulse observed in a recent experiment by Barreto, Reynolds, and Jurenka is given in terms of the proposed process.

Spectral Phenomena in Spark Discharges
Physical Review, 1930Two methods are described for measuring the differences in the time of appearance of the spectrum lines in sparks. The first is a refinement of the Kerr cell method previously used and a detailed description of its use is included. The criticisms of Gaviola of the method are shown not to apply.
