DESCRIPTION OF SOME PHENOMENA IN ELECTRIC ARC CATHODE REGION
RÉSUMÉ
Photographic observation of the cathode tip and near electrode region of an electric arc, working at atmospheric pressure in argon permitted to observe some interesting phenomena, which take place in this region, e.g. existence of a "dark zone" between the plasma column and the cathode, low frequency (f<0.1Hz) fluctuations of emitted light, existence of several hot spots on the cathode surface at the same moment, movements of the arc spot and modification of the cathode surface structure.
