Developing of EOS Model with Elliptical Beams for THz Devices

This report presents a design of an electron-optical system (EOS) with triple electron elliptical beams. A current of each beam is 31 mA and a dimension is 300×600 ¼m2. A magnetic field of 0,55 T is used for focusing of electron beams. A technology of fabrication and assembly of a model of EOS that contains a dispenser cathode, anode, collector and magnetic system is presented. In the course of experimental investigation of a model in impulse mode total current of 93 mA was obtained at cathode temperature of 1100°C and grid potential 900-1000 V. The realized design of a model with elliptical beams demonstrates the feasibility of creating of THz TWT on the basis of a similar EOS.
