Volkhova T. The works regime optimization of autophase devices of superhigh frequencies

The dissertation is devoted to create new optimization nonlinear models of autophase devices of superhigh frequencies (nonlinear model with space charge for non relativistic autophase devices and double-measured nonlinear model for autophase free electrons laser). The analytical models of the autophase lamp of progressive wave with azimuthally symmetric and nonsymmetric field and the noncogerent frequency transformer's accounting space charge field were created. The optimization of the autophase energy transformation mechanism accounting space charge field with variation method was done. The stability electron clots model in the free electrons laser accounting scattering electron velocities and changing noadiabatic fields was proposed. The new conditions of the clots stability were got. The double-measured nonlinear model for autophase free electrons laser accounting all new conditions was proposed.
