On the self-structuring of plasma in simple and multiple double layers

Summary form only given. Experimental investigations showed that when a positively biased electrode is immersed into cold diffusion plasma, at a certain threshold value of the applied voltage, a fireball spontaneously appears in front of it. It was proved that this complex space charge structure is bordered by an electrical double layer, which in certain experimental conditions is able to self-structure as concentrically multiple double layers. This new plasma entity is capable of certain specific nonlinear dynamics. A fractal theoretical model based on the scale relativity theory was built in order to explain the plasma self-structuring and the multiple double layers nonlinear behavior. The experimental and theoretical results were found to be in a good agreement.
