Streamers, sprites, leaders, lightning: from micro- to macroscales
Ute Ebert, Davis D. Sentman
"Streamers, sprites, leaders, lightning: from micro- to macroscales" was the theme of a workshop in October 2007 in Leiden, The Netherlands; it brought researchers from plasma phys…
Experiments on propagating and branching positive streamers in air
T. M. P. Briels, E. M. van Veldhuizen, Ute Ebert
This proceedings paper from 2004 contains figures of discharges in different gap lengths at the same potential that are not available elsewhere. The 2004 abstract: The evolution of…
Moving boundary approximation for curved streamer ionization fronts: Solvability analysis
Fabian Brau, Benny Davidovitch, Ute Ebert
The minimal density model for negative streamer ionization fronts is investigated. An earlier moving boundary approximation for this model consisted of a "kinetic undercooling" typ…
Positive and negative streamers in ambient air: measuring diameter, velocity and dissipated energy
T. M. P. Briels, J. Kos, G. J. J. Winands +2
Positive and negative streamers are studied in ambient air at 1 bar; they emerge from a needle electrode placed 40 mm above a planar electrode. The amplitudes of the applied voltag…
Positive and negative streamers in ambient air: modeling evolution and velocities
Alejandro Luque, Valeria Ratushnaya, Ute Ebert
We simulate short positive and negative streamers in air at standard temperature and pressure. They evolve in homogeneous electric fields or emerge from needle electrodes with volt…
Multiple X-ray bursts from long discharges in air
C. V. Nguyen, A. P. J. van Deursen, U. Ebert
A lightning surge generator generates a high voltage surge with 1.2 microsec. rise time. The generator fed a spark gap of two pointed electrodes at 0.7 to 1.2 m distances. Gap brea…
