A short history of a new generation of vacuum microwave devices - travelling wave tubes (TWT) is presented. Conventional single-beam tubes have been compared with multibeam ones of the same output parameters. The multibeam tubes show much lower supply voltage and higher efficiency. Computer codes for multibeam TWT design have been described and discussed. Some codes, although mentioned in numerous publications, are not commercially available and other cannot be sold outside USA (eg. synthetic code CHRISTINE). Problems of generation and precise focusing of many parallel beams with high current density. In the presented work only commercial codes were used. Simulation results of existing electron gun obtained with E-gun code and Omni Trak code have been compared with the experimental data. Omni Track, HiPi and Magnum Codes (Field Precision) were also used for simulation of the system for generation, focusing and collecting for multibeam TWT with seven beams. The initial parameters for the TWT were calculated using a synthetic code SYNTWT (Istok).
