In this paper optical space and time resolved measurements on the later development of Kanal (streamer) and Townsend discharges in nitrogen are treated. In both discharges fast luminous fronts (the so called ionizing waves) arise: in the streamer discharge between the primary streamer stage and the spark stage, and in the Townsend discharge during the transition to the glow. For the streamer di...

We designed and conducted a series of primordial-soup Miller-Urey style experiments with deuterated gases and reagents to compare the spark-discharge products of a "deuterated world" with the standard reaction in the "hydrogenated world". While the deuteration of the system has little effect on the distribution of amino acid products, significant differences are seen in other regions of the pro...

Diffuse discharge opening switches usually operate with gas mixtures containing attachers when short opening times are desired. For arc free discharge 1nitiation, a preionization source should produce a sufficient electron density at the time when the voltage rises across the discharge. Therefore, a preionizer must have 1) a short rise and fall time, 2) sufficient power, and 3) a sufficiently p...
