We describe new versions of high-harmonic gyrotrons with axis-encircling electron beams
developed on the basis of two (80-keV pulsed and 30-keV continuous wave) experimental …

Coherent subterahertz radiation is achieved in an electron cyclotron maser (large-orbit
gyrotron configuration) operating at a higher cyclotron harmonic in the continuous-wave …

A recently proposed method of decreasing the ohmic losses in long gyrotron cavities is
thoroughly studied. Its workability is proved using various simulations. A fourth-cyclotron …

We describe the small-signal theory of a backward-wave gyro-oscillator with a sectioned
quasi-optical system with the zigzag path of the operating wave beam. This theory explains …

A number of application require compact low-power gyrotrons with relatively low operating
currents. In order to provide the start of such gyrotrons, one should use long-length …

A typical problem of the development of high-harmonic short-wavelength gyrotrons, namely,
the competition between the operating wave and a parasitic fundamental-harmonic wave, is …

A typical problem of gyrotrons operating at high harmonics of the electron cyclotron
frequency is the suppression of parasitic near-cutoff waves excited at lower harmonics. In …

In low-power gyrotrons with weak electron-wave interaction, there is a problem of
determining the optimal length of the operating cavity, which is found as a result of a tradeoff …

We describe the small-signal theory of a travelling-wave-tube (TWT) gyro-amplifier with a
sectioned system of quasi-optical mirrors ensuring the zigzag path of the operating wave …

In this article, the possibility of obtaining an automodulation output signal in a powerful
(megawatt-level) gyrotron is investigated. Self-modulation of the output power can be …
