Abstract-Gyrotron with a sectioned cavity based on excitation of a far-from-cutoff operating mode
A typical problem of weakly relativistic low-power (especially in the case of operation at high cyclotron harmonics) is the use of long ensuring extremely high diffraction Q-factors for the operating near-cutoff waves. As a result, a great share of the rf power radiated by is spent in Ohmic losses. In this paper, we propose to use a sectioned with π-shifts of the wave phase between sections. In such a a far-from-cutoff axial mode of the operating having a decreased diffraction Q-factor is excited by the in a gyrotron-like regime.
(This paper is focused basically on the problems of the gyrotrons operating at high cyclotron harmonics in the terahertz frequency range)
