摘要

We present the results of the initial stage of studying the gyrotron-type devices with a novel electrodynamic system in the form of a zigzag quasioptical transmission line. The basic concept of the considered modification was proposed for the first time in 2018, particular versions of such devices with calculation results were described in a publication of 2021, and the first successful experiments were carried out and reported in early 2024. The electrodynamic system under discussion consists of mirrors that direct a quasioptical Gaussian beam along a zigzag trajectory in such a way that it periodically intersects the electron beam at the right angle. At the points of these intersections, electron-wave interaction occurs at a frequency close to the cyclotron frequency of electrons having initial transverse velocities. The work treats the features of such devices and the results of their theoretical analysis in detail and presents the results of the first experiments.
