摘要: The secondary ionization coefficient γ of a CaO film electrode is investigated taking into account the difference in breakdown voltage obtained by repeated applications. Such measurement performed under sinusoidal 0.5 Hz. If acts as cathode, gradually decreases and converges to an almost constant value after several breakdowns. From results, determined for each using Townsend’s criterion. first lower than those subsequent breakdowns, particularly steady state. considered originate from accumulated charges on electrode.
