This review concerns the theory of the avalanche multiplication of high-energy (0.1–10 MeV)
electrons in a neutral material, a newly discovered phenomenon known as runaway …

Microwave discharges (MD) are widely used as a source of non-equilibrium low pressure
plasma for different applications. This paper reviews the methods of microwave plasma …

A 670 GHz gyrotron with record power and efficiency has been developed in joint
experiments of the Institute of Applied Physics, Russian Academy of Sciences (Nizhny …

We report the observation of two-dimensional plasma filamentary arrays with more than 100
elements generated during breakdown of air at atmospheric pressure by a focused …

Recent studies of 110 GHz microwave discharges in air at atmospheric pressure have
demonstrated formation of a large array of quarter-wavelength-spaced plasma filaments …

We present a comprehensive model of plasma dynamics that enables a detailed
understanding of the ways the air plasma induced in the atmosphere in the wake of a laser …

Regular two-dimensional plasma filamentary arrays have been observed in gas breakdown
experiments using a pulsed 1.5 MW, 110 GHz gyrotron. The gyrotron Gaussian output beam …

A scheme is proposed for detecting a concealed source of ionizing radiation by observing
the occurrence of breakdown in atmospheric air by an electromagnetic wave whose electric …

Gas breakdown in the millimetre-wave frequency band is an interesting phenomenon in
nonlinear dynamics such as self-organized structure formation. We observed the transition …

Electron density and neutral gas density have been measured in a non-equilibrium air
breakdown plasma using optical emission spectroscopy and two-dimensional laser …
