Abstract
The electron-emission characteristics of dielectrics irradiated with electron beams with a current density of about 10−5 A cm−2 have been experimentally investigated. An ambiguous relationship between the secondary electron-emission properties, the charged-surface potential, and the positive and negative charges accumulated in the surface region of dielectric targets is demonstrated. The character and values of various experimentally observed time charging constants, inconsistent with a number of theoretical models and estimates, are qualitatively explained.
