Abstract

The results of modeling the sub-millimeter TWT electron optical system with a low-voltage control based on the experimental data of the planar array cathode-gate structure with carbon nanostructures are performed in this work. It is shown that the cathode-gate structure including in the analyzed field emission electron gun manufacturing by lithographic processes and CVD technologies may provide the formation a long electron beams with current density of 15,5 A/cm².
