2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).
We present the results of experiments on generation of sub-nanosecond 90-GHz superradiant (SR) pulses with a record peak power of ~150 MW. Such pulses are produced based on excitation of a surface wave in an oversized waveguide with 2D (double-period

Low inertial transition of the field emission into explosive electrons emission at the cathode and related fast-rise-time electron beam formation are of interest in a phase-stable excitation of relativistic high-power microwave oscillators. We presen

We present the results of experiments on generation of high-power superradiant (SR) pulses by an extended electron bunch moving in a cylindrical surface-wave structure with two-dimensional periodical corrugation. In such a structure, azimuthally prop

Delay stage of pulsed breakdown in air gap lasts longer than the time of electron free acceleration from the cathode to anode. When the voltage rise time in the gap is comparable with this time interval and electric field strength is sufficiently hig

We develop two approaches for coherent summation of Cherenkov superradiance (SR) pulses in order to obtain generation of electromagnetic fields of extremely high intensity. The first method is associated with correlating the phase of SR emission to t

We present an analysis of the characteristics of the noise from a magnetized high-current electron beam at a nanosecond-long interval since the explosive electron emission onset on the graphite cathode by applying accelerating pulses with an amplitud

The first experiments on the observation of short pulsed superradiant (SR) emission with the excitation of a surface wave by a relativistic electron bunch moving in an oversized corrugated waveguide were performed. Subterahertz SR pulses with a centr

For relativistic Cherenkov devices, we investigate the process of high-power microwave pulse generation with its phase correlating to the sharp edge of an e-beam current pulse. Our theoretical consideration is referred to quasi-stationary and superra

The stability of the injection of short electron beams and the dynamic processes that occur during their transport were experimentally studied. Beams of energy 200-300 keV, current of 1-1500 A, and duration of 0.05-3 ns with a current rise time of 30
