ABSTRACT:
A microtip emissive cathode electron source has a series of cathode conductors carrying a plurality of microtips and a series of grids. Each of the electrodes of at least one of the series is in contact with a resistive layer having meshes, a group of the microtips facing each mesh. A conductive element faces the interior of each mesh in front of the group of microtips corresponding to the mesh and is in contact with the resistive layer.
