A pulsed drift tube has been used to measure the electron drift velocity in methane over the range of E/N from 10 to 1000 Td. In addition, measurements of the positive ion mobility and ionization coefficient have been made over the range of E/N from

We have calculated α and η, the ionization and attachment coefficients, and (E/N) *, the limiting breakdown electric‐field–to–gas‐density ratio, in SF6 and SF6 mixtures by numerically solving the Boltzmann equation for the electron energy d

An experimental technique has been developed for the absolute measurement of the density of a surface charge on a dielectric. The apparatus is described and includes provision for producing the surface charges by electron and ultra-violet irradiation

Measurements have been made of the charge density produced on dielectric surfaces by contact with metals of known difference in work function in vacuo. The injected charge density is dependent on the metal work function and, therefore, described by e

An experimental investigation has been made of the incipient condensation of water vapour on gold by observations of light scattering. Results have been obtained for surfaces well washed by condensation and for surfaces which, after having been washe

Charge carrier mobility has been determined for four characterized polythenes in vacuo, using a surface charge dissipation technique. The mobility has also been examined in two of these polythenes impregnated with iodine. The values of mobility obtai

Contact between a metal sphere and plane specimens of a synthetic polymer has been investigated experimentally. The area of contact has been determined, for a range of contact loads, by measurement of the surface charge retained by the polymer after
