“…Figures 3 and 4 show the transient glow duration plotted against overvoltage for nitrogen and air at various values of gas pressure and gap spacing. In agreement with the results of other authors (Buss 1930, Farish 1965, Farish and Tedford 1967 Figure 4. tg plotted against A V in air.…”

“…The 10.8 cm diameter uniform-field electrodes and discharge vessel employed in the present work have been described in detail previously (Blair and Farish 1967). The impulse generator, shown in figure 2, was of the switched-cable type; it produced single, flat-topped voltage pulses of up to 50 kV, 1.7 ps long, with a rise time (10%-90%) of 20 ns.…”

“…Rogowski et al (1927) and Buss (1930) noted that, when static breakdown took place between uniform-field electrodes in air, the voltage across the gap collapsed in two steps. The first step was associated with the onset of a diffuse glow discharge and the second with the subsequent formation of a filamentary arc discharge.…”

The duration of the transient glow discharge preceding the arc stage of uniform-field gas breakdown has been measured for nitrogen and air. These measurements have been made for gaps up to 3 cm at gas pressures of 300 and 500 Torr, in the overvoltage range 4%less-than-or-eq, slantΔVless-than-or-eq, slant20%. It has been shown that the glow duration is strongly dependent upon the equivalent series circuit resistance, and this explains the poor agreement between the results of previous investigations.During spark conditioning, a form of breakdown consisting of a very diffuse glow, with no subsequent arc discharge, has been observed. Some of the factors affecting the occurrence of this interesting phenomenon have been studied.

“…These negative ions SF 6 can easily release electrons at a very low energy of only 0.05 eV [17], so that the electrons are readily supplied from such negative ions by electric field detachment [18] or photoionization in front of the streamer.

“…A recent experimental study (Blair and Farish 1967) suggests that the simultaneous generation of more than one initial electron by a single irradiation particle in a discharge gap is important for the analysis of the experimentally obtained statistical distribution of breakdown time-lags by the Townsend mechanism. An irradiation, a single particle of which can generate more than one initial electron both, or either, at the cathode and in the gas, as used in the above study, will here be called high-energy-particle irradiation.…”

Recent experimental work suggests that the simultaneous generation of more than one initial electron by a single irradiation particle in a discharge gap has important effects in the statistical distribution of breakdown time-lags by the Townsend mechanism. To take account of these effects, earlier theories, as given by Legler, are extended in the present paper. General formulae for time-lag distributions are obtained and typical numerical examples are compared with a digital computer simulation study to confirm the consistency of the calculations and to find the limitation due to approximation. An approximate, but direct, method of measuring the formative time-lag distribution when breakdown is initiated by a single electron is suggested.
