This paper presents the results of experimental testing of diode electron guns with sheet and multiple electron beams based on thermionic minicathodes for TWT of terahertz frequency range. The results of study in pulse mode of impregnated thermionic blade cathode with linear dimensions 0.1×0.7 mm with a current density of 114 A/cm2 are presented. A version of the five-beam electron gun is proposed...
In this paper we present the computer analysis of magnetic focusing sheet electron beam with low perveance in the electron-optical systems with an electron gun based on thermionic cathode with a current density of 100 A/cm2 at the distance of tunnel 25 mm. The results of experimental study in the diode mode of impregnated thermionic cathode with linear dimensions 0,1 × 0,7 mm have shown the feasibility...
