Annotation

The results of AFM-researches of the glass K-208 samples are presented surfaces irradiated with electrons with energies of 20÷50 keV at a particle flux density φe = 3,0•1010 ÷ 1,0•1011 cm –2s–1. The samples were irradiated in a vacuum chamber at pressure of 10–4 Pa. Shown that changes in morphology of glass K-208 upon irradiation with medium-energy electrons occur due to electrostatic discharges, which resulted in forming microprotrusions and discharge channels, as well as due to forming of gas-filled bubbles.
