Electron density fluctuations accelerate the branching of streamer discharges in air
A. Luque, U. Ebert
Branching is an essential element of streamer discharge dynamics but today it is understood only qualitatively. The variability and irregularity observed in branched streamer trees…
Probing photo-ionization: simulations of positive streamers in varying N2:O2 mixtures
Gideon Wormeester, Sergey Pancheshnyi, Alejandro Luque +2
Photo-ionization is the accepted mechanism for the propagation of positive streamers in air though the parameters are not very well known; the efficiency of this mechanism largely…
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…
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…
The multiscale nature of streamers
Ute Ebert, Carolynne Montijn, T. M. P. Briels +4
Streamers are a generic mode of electric breakdown of large gas volumes. They play a role in the initial stages of sparks and lightning, in technical corona reactors and in high al…
