Abstract
The field-induced prebreakdown currents that flow between vacuum-insulated high voltage electrodes in the field range 10-30 MV.m-1 result from a "non-metallic" electron emission mechanism which is localised at micron-sized anomalous surface inclusions. The present paper reports on recent experimental evidence, including emission image and spacially-resolved energy analysis data, which suggests that the emission is derived from a field-induced hot-electron mechanism (FIHEE) associated with metal-insulator-metal (MIM) microstructures.
