New approach to design of electron-optical system of powerful tethrodes with grid control

The goal of this paper is to describe a new approach to design of electron-optical system of powerful tethrodes. Was presented the use of simulated electronic multi-beam flow this electron deceleration at anode. Using calculating o electron trajectory and experimental study was designed a cathode-grid assemble with control and acceleration grid. It was shown, that such approach it is possible to design a powerful tethrode higher output power and efficiency rather then by standard tethrode.
