Abstract

An experimental study is reported of the delay-time statistics for electrical breakdown in air in intense electric fields E = 100–200 kV/cm. The dependence of the statistical delay time tst for the breakdown on the gap width δ is obtained for various fields E. With E = 100 kV/cm and with an air pressure of p = 1 atm, the delay time is ∼20 nsec and depends weakly on δ in the range δ5 = 3–10 mm. As the gap width is reduced from 3 to 2 mm, tst increases sharply, reaching 3000 nsec. The gap width at which the sharp increase in tst sets in decreases with increasing E. The gap-width dependence of tst has the same nature at different pressures. The minimum delay time has been measured to be ∼8 nsec.
