We present and analyze characteristics of the runaway electron flow in a high-voltage (the
voltage rise rate of up to 1.5 MV/ns) air-filled electrode gap with a strongly nonuniform …

High-voltage picosecond breakdown of an atmospheric-pressure air-filled coaxial line in the
radial electric field of a propagating transverse electromagnetic wave has been studied both …

The conditions under which runaway electrons are generated in a gas diode with a strongly
nonuniform electric field created by electrodes of specific geometry have been investigated …

The main aim of the present paper is to clarify the influence of the SF 6 fraction in the SF 6/N
2 mixture on the breakdown voltage. For this, the two-dimensional axisymmetric fluid model …

The mechanism of runaway electron generation at gas pressures from a few atmospheres to
several tens of atmospheres is proposed. According to this mechanism, the electrons pass …

The results of an investigation of a self-sustained subnanosecond discharge in nitrogen at a
pressure of 6 atm are presented. A high voltage pulse with a front of approximately 770 ps at …

The first results of study of the compression of a picosecond runaway electron flow in an air
electrode gap by a pulsed guiding magnetic field increasing along the electron trajectory by …

A mechanism for the initiation of explosive electron emission at the interface between the
cathode and a dense gas is proposed. It is based on the accumulation of positive ions …

We investigate the formation of a secondary flow of runaway electrons with energies on the
order of 100 keV in an air gap after the passage of a primary picosecond flow of similar fast …

The generation of energetic electrons by the streamer with a negatively charged head is
analyzed using a self-consistent two-dimensional Particle-in-Cell Monte Carlo collision …
