Experimental study of the spatio-temporal development of meter-scale negative discharge in air

P. O. Kochkin, A. P. J. van Deursen, U. Ebert

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

Growing discharge trees with self-consistent charge transport: the collective dynamics of streamers

Alejandro Luque, Ute Ebert

We introduce the generic structure of a growth model for branched discharge trees that consistently combines a finite channel conductivity with the physical law of charge conservat…

Why isolated streamer discharges hardly exist above the breakdown field in atmospheric air

A. B. Sun, J. Teunissen, U. Ebert

We investigate streamer formation in the troposphere, in electric fields above the breakdown threshold. With fully three-dimensional particle simulations, we study the combined eff…

Streamers in air splitting into three branches

L. C. J. Heijmans, S. Nijdam, E. M. van Veldhuizen +1

We investigate the branching of positive streamers in air and present the first systematic investigation of splitting into more than two branches. We study discharges in 100 mbar a…

PTFE treatment by remote atmospheric Ar/O2 plasmas: a simple reaction scheme model proposal

E. A. D. Carbone, M. W. G. M. Verhoeven, W. Keuning +1

Polytetrafluoroethylene (PTFE) samples were treated by a remote atmospheric pressure microwave plasma torch and analyzed by water contact angle (WCA) and X-ray photoelectron spectr…

High order fluid model for streamer discharges. II. Numerical solution and investigation of planar fronts

A. H. Markosyan, S. Dujko, U. Ebert

The high order fluid model developed in the preceding paper is employed here to study the propagation of negative planar streamer fronts in pure nitrogen. The model consists of the…

High order fluid model for streamer discharges: I. Derivation of model and transport data

S. Dujko, A. H. Markosyan, R. D. White +1

Streamer discharges pose basic problems in plasma physics, as they are very transient, far from equilibrium and have high ionization density gradients; they appear in diverse areas…

Dual view FIDA measurements on MAST

C. A. Michael, N. Conway, B. Crowley +11

A Fast Ion Deuterium Alpha (FIDA) spectrometer was installed on MAST to measure radially resolved information about the fast ion density and its distribution in energy and pitch an…
