Regime of trapping and adiabatic deceleration of electrons in a sectioned electron RF generator

As a method for the realization of the regime of trapping and adiabatic deceleration of particles in relativistic RF electron autooscillators, the scheme of the twystron with a self-exciting input section and an output section where the deceleration of electrons is provided by profiling the parameters of the system is suggested. It is shown that for a wide range of parameters, almost total trapping of the particles and, therefore, high-efficiency stable RF generation, can be achieved.
