Properties of the plasma shell of a low-inductive vacuum spark are investigated. High-frequency oscillations in the range 1–120 MHz are registered in the current circuit. Spectral measurements of the plasma elemental composition and temperature are performed. The presence of oscillatory processes is also observed in spectral emission lines. Ring formations (with periods of 0.15–0.3 mm) and cellular structures (with sizes of 0.1–0.5 μm) are fixed on the electrode surface. Plasma waves are suggested to explain the registered oscillatory processes.
