Analyzing of the characteristics of low-voltage multibeam mean-power electro-vacuum distributed MW amplifier with transverse interaction on the base of multielectrode electron-optical system with a matrix graphite field emitter array

This paper considers a two-stage distributed multibeam microwave amplifier containing a high-voltage multielectrode electron gun with a matrix graphite FEA and two identical two-dimensionally periodical WISs designed as a multistage ladder structure in a rectangular waveguide. The analyzed results are presented for the electrodynamical characteristics of the waveguide and electron-optical systems.
