Field emission properties of a blade cathode based on a carbon foil

摘要

The goal of the research is property investigation of blade cathode based on TEG (thermally expanded graphite). The cathode-modulator assembly was placed into a glass bottle (anode) with a conductive coating by ITO (Indium tin oxide), which was previously covered by phosphor. Tests were performed in an evacuation chamber at a pressure of about 10−6 Torr.
