Experimental study on hard X-rays emitted from metre-scale negative discharges in air
P. O. Kochkin, A. P. J. van Deursen, Ute Ebert
We investigate the development of meter long negative discharges and focus on their X-ray emissions. We describe appearance, timing and spatial distribution of the X-rays. They app…
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…
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…
Experimental study of hard X-rays emitted from meter-scale positive discharges in air
P. O. Kochkin, C. V. Nguyen, A. P. J. van Deursen +1
We investigate structure and evolution of long positive spark breakdown; and we study at which stage pulses of hard X-rays are emitted. Positive high-voltage pulses of standardized…
Probing background ionization: Positive streamers with varying pulse repetition rate and with a radioactive admixture
S. Nijdam, G. Wormeester, E. M. van Veldhuizen +1
Positive streamers need a source of free electrons ahead of them to propagate. A streamer can supply these electrons by itself through photo-ionization, or the electrons can be pre…
Probing photo-ionization: Experiments on positive streamers in pure gasses and mixtures
S Nijdam, F M J H van de Wetering, R Blanc +2
Positive streamers are thought to propagate by photo-ionization whose parameters depend on the nitrogen:oxygen ratio. Therefore we study streamers in nitrogen with 20%, 0.2% and 0.…
