Peculiarities of Optimizing the Subsystems of a Continuous-Wave Gyrotron with a Generation Frequency of 0.26 THz at the Fundamental Cyclotron Resonance

Abstract

We present the results of developing the main units of a gyrotron operated in the continuous-wave regime with a generation frequency of 0.26 THz. To improve selection of the operating mode in a oversized electrodynamic system, the gyrotron works at the fundamental cyclotron harmonic, which anticipates the use of a cryomagnet with a maximum magnetic field of 10 T, which does not require filling with liquid helium. The results of optimizing the electron-optical system, the cavity, and the quasi-optical converter of the output radiation are presented, and the control system, which is developed for the gyrotron setup, is described.
