In situ measurement of electrical conductivity of alumina under electron irradiation in a high voltage electron microscope

Radiation induced conductivity (RIC), thermally stimulated conductivity (TSC) and radiation induced electrical degradation (RIED) are major concerns of insulating ceramic materials under the effects of flux, electric field and temperature and may lessen their performance in fusion reactors. In situ measurements of the electrical conductivity of single crystal α-Al2O3 (alumina) using the standard electric guarding technique has been performed …
