A flux compression generator (FCG) is a device generating a high-power electro-magnetic pulse by compressing magnetic flux with the help of explosion. The physical properties of components and materials used for FCG manufacturing and available on the

In this paper, we review and compare HPM sources operating without a magnetic field to guide the electron beam that are capable of producing high-power microwave (HPM) pulses with a duration of about 100 ns. The proposed analysis summarizes multi-yea

Design of helical flux compression generator with double-end initiation is described. The developed design approach makes it possible to increase the power in the load by 60\% and shorten the rise time of the pulse by 83\% in comparison with a conven

The electrostatic cumulation of current density in relativistic vacuum diodes with ring-type cathodes is described theoretically and confirmed experimentally. The distinctive feature of the suggested cumulation mechanism is a very low energy spread o

We consider the effects of shot noise and particle energy spread on statistical properties of Cherenkov and quasi-Cherenkov superradiance emitted by a relativistic electron beam. In the absence of energy spread, we have found the root-mean-square dev

Shot noise, intrinsic to the ensemble of nonisochronous electrons-oscillators, is the cause of statistical fluctuations in cooperative radiation generated by single-pass cyclotron-resonance masers (CRMs). Autophasing time --- the time required for th

A drastic cumulation of current density caused by electrostatic repulsion in relativistic vacuum diodes with ring-type cathodes is described theoretically and confirmed experimentally. The distinctive feature of the suggested cumulation mechanism ove

We study the features of cooperative parametric (quasi-Cherenkov) radiation arising when initially unmodulated electron (positron) bunches pass through a crystal (natural or artificial) under the conditions of dynamical diffraction of electromagnetic

We use quantum-electrodynamical approach to study the initial stage of Dicke superradiance from a system of two-level atoms. Applying the zeroth-order Magnus approximation, we obtain the expression for the mean number of quanta emitted in the presenc
