Modeling of discrete interaction processes in traveling-wave tube with resonator slow-wave structures of microwave and EHF ranges
P. 405-412.
In this paper, a model describing the discrete interaction of a traveling-wave tube (TWT) with resonator slow-wave structures (SWSs) is considered. The problems of development of TWT are analyzed, and the approaches to finding solutions for these problems are considered. When simulating a TWT section, a chain of sextapoles with combined field and current terminals is used. The developed model served as a basis for the development of the software complex VEGA which will be used later for the design of TWT in microwave and EHF bands.
