Aims of investigation: studying of single-particle dynamics in combined external magnetostatic pump field of free-electron laser/maser and elucidation of impact of walls of ideally conducting regular drift-tubes on charged-particle dynamics. Investigation method: complementary analytical calculations and numerical modeling in the framework of totally three-dimensional electromagnetic model using methods of physical electronics. Analytical expressions for the trajectories of test electrons in the magnetostatic pump field of planar hybrid free-electron laser/maser are obtained and numerically modeled, in the Darwin model using the method of Green's function induced charge and current densities on the walls of indefinite circular cylindrical drift-tube are calculated and concepts of their efficient numerical simulations was being developed.
