Oscillations of the Positive Column Plasma Caused by Propagation of Ionization Wave and the Two-Dimensional Structure of Striations
Abstract
Time resolved measurements of the electron energy distribution function (EEDF) and plasma potential in longitudinal and radial directions under the presence of S- and P- striations in neon were performed. The potential was measured with high spatial resolution by means of simultaneous displacement of electrodes relative to stationary probe in different radial positions. A method of decomposition of the spatio-temporal structure of the potential is proposed. The potential is shown to be composed of the plasma oscillations and the ionization wave potential Experiments revealed two-dimensional structure of the striation potential field. Qualitative considerations of the origins of this structure are discussed.
