In this review we describe a transient type of gas discharge which is commonly called a
streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers …

The review provides an up-to-date overview and discussion of phenomena related to
positive streamer breakdowns in short uniform and non-uniform field (corona) gaps. The …

Guided ionization waves, or plasma streamers, are increasingly important for many
applications in spanning materials processing and biomedicine. The highly reproducible …

We investigate the development of metre long negative discharges and focus on their x-ray
emissions. We describe appearance, timing and spatial distribution of the x-rays. They …

Streamer discharges are the primary mode of electric breakdown of air in lightning and high
voltage technology. Streamer channels branch many times, which determines the …

We study negative streamers in ambient air using a 2D axisymmetric fluid model. Depending
on the background electric field, we observe accelerating, steady and fading negative …

A numerical model with physical timing and grid spacing of 3 m is applied to studying the
progression (including step** and branching) of negative lightning stepped leader. The …

We study the development of a negative discharge of about 1 MV driven by a Marx
generator in an air gap of 1–1.5 m, at standard temperature and pressure. We show the …

Atmospheric electricity has been intensively studied during the last 30 years after the
discovery in 1989 of different forms of upper atmospheric electrical discharges (so–called …

We use the Low Frequency Array (LOFAR) to probe the dynamics of the step** process of
negatively charged plasma channels (negative leaders) in a lightning discharge. We …
