Abstract:

Research was undertaken in May 1951 to develop a high current density electron gun of the line-focus type. Two types have been developed. One design uses a single potential anode with an elliptical shaped cathode to concentrate the current into a narrow ribbon-like beam which is less than .040 inch wide. The second design uses a two potential gridded anode structure. The current is concentrated by a factor of 10 from the cathode to the narrowest part of the beam, where the current density is 1 amperesq.cm.
