Prospects of Creation of Pulsed 1 THz High-Harmonic Gyrotrons of the Kilowatt Power Level for Plasma Applications

The possibility of creating gyrotrons operating at the frequency of 1 THz with the output wave power at the level of several kilowatts is being investigated. Such gyrotrons should be used to provide a gas-discharge plasma; this is a way to create a stable point-like source of extreme ultraviolet radiation. In this work, we discuss possibilities for experimental realization of pulsed 1 THz third-cyclotron-harmonic large-orbit gyrotrons with the kW level of the output wave power. In particular, the use of complicated schemes of operating gyrotron cavities aimed to both improve the selectivity of the high-harmonic operating and to increase of the output power is described.
