Desynchronization of striations in the development of ionization turbulence
Abstract
Nonlinear properties of ionization instability in an argon glow discharge are demonstrated experimentally and numerically. Dislocation-like topological defects indicate strong nonlinearity which desynchronizes the wave of stratification. The evolution of a defect sensitively depends on striation amplitude and leads to spatio-temporal chaos. In a chaotic state movement of striations is interrupted by evolution of defects and resembles a directed stochastic motion of colliding, annihilating and creating particles.
