Multibeams TWT of O-type with sheet electronic beams

The mathematical model of a multibeam TWT with sheet electronic beams on a wavy bent rectangular waveguide with use of waves Hm0 is formulated. Features of designs and interaction of electronic beams with waves Hm0 are noted. Calculation results of multibeams TWT are resulted, it is shown, that a fourbeam TWT has rated output power of 11 W, gain of 31 dB at frequency of 559 GHz.
