- Аннотация: When irradiating K-208 and CMG glasses by 20-keV electrons with flux densities of 10(10) < phi(e) < 2 x 10(11) cm(-2) s(-1) in vacuum 10(-4) Pa, electrostatic discharges accompanied by plasma emission and destruction of glass surfaces were observed. Examination of glasses by atomic force microscopy (AFM) showed significant difference in structural changes of surfaces of K-208 and CMG samples irradiated by equal flux densities within the range from 2.0 x 10(10) to 9.0 x 10(10) cm(-2) s(-1) that can be explained by different mechanisms of removal of charge accumulated in glasses. Surface discharges generating channels on surfaces of K-208 and CMG glasses appear when phi >= 7.4 x 10(10) cm(-2) s(-1) and phi >= 8.7 x 10(10) cm(-2) s(-1) respectively. In average, if radiation conditions are the same and phi >= > 1.4 x 10(11) cm(-2) s(-1), the channels are 1.5 times deeper in K-208 than in CMG
