Description
Summary:A research of the vacuum spark plasma properties in the near-electrode area is considered. Results of the observations of the high-frequency electrical oscillatory discharges in the 1-110 MHz range are presented. Plasma element composition and temperature have been analyzed with a spectrometer. It contains the study of the microrelief of the electrode surface. Also observations of the 80-350 nm cellular structure formation are represented. Finally, it describes a proposed possible mechanism of the surface formations occurrence.
