In many operations such as breaking a circuit, arc initiation, ion emission from molten metals, the ensuing plasma interacts with electrodes, even in low voltage (3 V) conditions. The physics of metal behaviour in such cases is discussed, and the evi

Ionization currents in spectroscopically pure helium between plane parallel silver electrodes at separations up to 0.75 cm were measured in the range 6 leq E/p leq 100 v cm-1 mmHg-1 and 3 leq p leq 115 mmHg where E is the applied electric field and p

The dependence of the secondary emission from the cathode on the energies of the impinging positive ions is of importance in the mechanism of the corona, or asymmetric, discharge through gases. In particular, it is important to find whether positive

In elucidating the phenomena of breakdown it is necessary first to find the general mechanism by which the various processes of ionization interact to produce the necessary amplification of current, and then to identify the particular ionization proc

This paper describes a theoretical investigation of the mechanism of ejection of secondary electrons at the cathode surface in electric discharges in hydrogen. Theoretical estimates of the magnitude of the coefficient δ/α (due to photons) are obtai

The arc phase of electrical contacts of the type used in low-power communication engineering is discussed from the point of view of the fundamental processes which occur both in the arc column and at the electrode surfaces. A theory of electrode eros

It was shown in part I that there is a need for further experimental data on the drift velocity W of ions in gases such as nitrogen and argon where there are still unresolved problems. In addition, measurements of quantities such as the diffusion coe

The time rate of growth of ionization currents in a gas in a uniform electric field greater than that corresponding to the static sparking potential is investigated theoretically. This theoretical analysis is then applied to the breakdown of a gas at
