Abstract :
The three-dimensional self-consistent mathematical model of a relativistic gyro-TWT with an irregular electrodynamic system (EDS) was described in Kuraev (1979) and Kuraev et al. (1988). The problem of the efficient optimization of gyro-TWTs over the frequency band is discussed. The optimized waveguide profile and magnetostatic field distribution are determined and the atomic function is defined to solve equations. The application of atomic functions in the approximation of the waveguide profile and the magnetostatic field distribution makes it possible to predict new effective mechanisms of interaction in a gyro-TWT with an irregular electrodynamic system and inhomogeneous magnetostatic fields
