Abstract

A sectioned oscillator (twystron with the self-exciting input section) is studied as a method for realization of the regime of trapping and adiabatic deceleration of electrons in CARMs. It is shown that the achievement of almost total trapping of the electron beam and, therefore, of a high electron efficiency, is possible when the first section is a Bragg cavity with the distributed feedback. Experimental realization of the CARM-twystron in the regime of trapping at the fundamental cyclotron harmonic with the wavelength of 8 mm, the electron beam current and voltage of 100 A and 500 kV respectively, and the estimated output RF power of 20 MW ith the efficiency of 40-50%, is being in the process
