Abstract: An external grid-controlled hot cathode array electron gun, including an insulated cathode base, a filament, a plurality of hot cathode emission elements, and a grid-controlled structure is disclosed. In one aspect, the grid-controlled structure includes an insulated grid-controlled structure body and a plurality of through holes. One side of the grid-controlled structure body abuts against the cathode base to clamp the filament between the grid-controlled structure body and the cathode base and the plurality of hot cathode emission elements are inserted into the plurality of through holes respectively.
