The effect of electron irradiation of K-208 glass on the contamination of its surface by high molecular weight compounds

The effect of electron irradiation of K-208 glass on the process of deposition of the products of thermostimulated gas emission from a high molecular weight composite is studied. The samples are irradiated in a vacuum chamber at a pressure of 10−4 Pa with electrons with an energy of 30 keV at flux densities ranging from 1010 to 2 × 1011 cm−2 s−1. The sample surfaces are investigated by the methods of atomic force microscopy (AFM). It is shown that the formation of impurity films is significantly affected by the surface structural changes caused by electrostatic discharges, the nature of which depends on the electron flux density. © 2015, Pleiades Publishing, Ltd.
