Abstract
A cathode of a crossed field device includes a first electrode and a second electrode disposed about and dielectrically spaced from the first electrode. In a preferred embodiment the electrode comprises a pair of electrodes, a first one of the pair being a masking electrode disposed about and dielectrically spaced from the first electrode and a second one of the pair being an emitter electrode disposed about and dielectrically spaced from the masking electrode.
