Sites of Initiation of Explosive-Emission Processes on the Surface of Single-Crystal and Coarse-Grained Polycrystalline Copper

Results of a study of sites of vacuum breakdown initiation on the electrolytically polished surface of single-crystalline and coarse-grained polycrystalline copper are presented. The coincidence of cathode erosion traces with sites of dislocation outcrops has been established.
