摘要：

Potassium glass was irradiated by 10, 30 and 50 keV electron beams of various diameters and the time decay of potassium x-radiation was measured. These measurements were complemented by SEM observation of the etched cross sections of exposed areas and potassium depth concentration profiles in order to observe structural changes in the glass. Whilst the temperature increase remained low, the length of the incubation period was inversely proportional to the specimen current density and a possible explanation of this phenomenon was suggested.
