Pulsed electron field emission from prepared conductors
Abstract
The feasibility of using dielectric coatings to suppress the electron emission of metal cathodes subjected to pulsed electric fields is studied. It is found that dielectrics could suppress emission completely up to 300-400 kV/cm, and unlike bare metals, could partially suppress emission after having passed significant current at fields up to 0.6 MV/cm.
