SPECTROSCOPIC ANALYSIS OF PREBREAKDOWN-PHASE FROM POSITIVE CORONA INTO SPARK IN N2
G.H. BauerInstitut fuer Physikalische Elektronik, Universitaet Stuttgart, F.R.G.
Abstract
The propagation of prebreakdown (streamer) from a quasistationary positive point-to-plane corona into spark in N2 is investigated by spatial and time resolved spectroscopic methods. Two luminous fronts, starting from the anode point, are found to traverse the gap before the bright spark occurs which is correlated to the collapse of the applied voltage. An evaluation of the spectroscopic results and their correlation to the electric current give information about data like diameter, velocity of the first front (streamer) and its gas temperature, electron energy, electric field and number resp. density of electrons.
