ABSTRACT

A self-consistent two-dimensional nonlinear theory has been formulated of a relativist O-type TWT with slow-wave structure TWT. This structure represents an arbitrarily-irregular smooth waveguide in which the electron interaction forces are averaged. Equations of excitation have been derived by the coordinate transformation procedure.
A solution to the problem of optimizing the relativist O-type TWT efficiency has been found using the atomic functions to approximate the sought-for optimal slow-wave structure profile. A new mechanism for the efficiency-optimized interaction has been disclosed, enabling the process of phase synchronized focusing of an electronic packet (its center is coincident with the nodal point of field forces) to be sequentially repeated and the power to be extracted from an electron bunch (the mode of the bunch is kept at a maximum of the retarding field phase).
