Abstract :
The results of calculation of a dynamic defocusing in TWT are produced on the basis of two-dimensional disc-ring model of an electronic beam. Is shown, that the smoothly varying magnification of a magnetic field in the last third of output section TWT practically eliminates a dynamic defocusing at maintenance of output parameters.
